HOW TO SAVE MONEY & MAKE YOUR AIR CONDITIONER LAST LONGER
Replacing yourair conditioning filter regularly will make your air conditioner run smoother, improve its efficiency, can prolong the life and save you money on your utility bills. When you do not replace your air conditioning filter indoor air pollutants such as dirt, dust and grime impede the flow of clean air, forcing it to bypass the filter with this action the dirt gets carried directly into the evaporator coil. This is a bad, as the coil is the part of your air conditioner that absorbs heat, you want to keep the coil clean to keep it functioning smoothly and to prevent your compressor and fans from failing.
If you or anyone in your family suffers from asthma or other breathing problems, keeping you indoor air clean by changing the filter will keep you healthier, and breathing easier.
Where is your air conditioner filter?
Your air conditioning filter will be located somewhere along the duct that returns air from the house and to the air conditioner. Filters are often located in the air conditioner itself or in ceilings, walls or furnaces.
What kind of an air conditioning system do you have?
Many air conditioning have filters made just for that model. Air conditioning can also use different filtration methods to clean the air. To determine which system you have, remove the filter and if you are unsure of size or type take it along to the store, and get exactly the filter to fit your ac model.
How ofter do I need to change the air conditioner filter?
If your air conditioning unit is using disposable rather that reusable air conditioning filter, depending on where you live it is a good idea to check your air conditioning filter every month. If you live a rural community with dirt roads, have pets, smoke, or live in a city with a lot of pollution you may need to replace your filter every month during the summer season.
Saving money on your utility bill
If you do not change your a/c filer during heavy use you will put a heavier strain on the unit, which will work hard, and break sooner. The cost of a/c filters in nominal in comparison to added costs each month on your utilities, and having to come out of pocket for a large expenditure when you have to purchase a new a/c unit.
Remember this fact; Keeping the filter clean can lower your air conditioner’s energy consumption by 5%–15%.

Change the air conditioner’s filters regularly Dirty filters restrict air flow, reduce efficiency and worst case, can cause the evaporator to ice up. Dirty filters reduce the efficiency of the air conditioner. At present, in some cases a filter for removing harmful substances is always attached to the return opening of the circulating air conditioner. Ensure that the air conditioner’s filter is changed on a regular basis, optimally every 30 days. Cleaning a dirty air conditioner filter can save 5 percent of the energy used.
No, the power to remove particles, including micro-organisms, does not mean that filter and portable air cleaning devices are cleaning all the of the indoor air pollutants from inside your home, but these air cleaning devices do have the capability of reducing adverse health effects from indoor pollutants for individual such as children, the elderly, and people with asthma and allergies.
The use of clean air filters is your best defense against indoor air pollutants. This is the simplest way to regulate or eliminate the sources of pollutants, and to ventilate a home with clean out of doors air. While air cleaning devices may help to manipulate the levels of airborne allergens, particles, or, in a few cases, gaseous pollutants in a home, they may not remove all health hazards such as noxious gases from indoor air pollutants.
Air Pollutants Indoors
What are the pollutants that can affect our indoor air quality in a home:
* Particulate matter can includes dust, smoke, pollen, animal dander, tobacco smoke, particles generated from combustion appliances such as cooking stoves, and particles associated with tiny organisms such as dust mites, molds, bacteria, and viruses.
* Gaseous pollutants are noxious and come from combustion sources.These sources include gas cooking stoves, vehicle exhaust, and tobacco smoke. They also come from building materials, furnishings, and the use of products such as adhesives, paints, varnishes, cleaning products, and pesticides.
When you are making decisions about using air cleaning devices, consumers should also consider:
* Installation: In-duct air cleaning devices have certain installation requirements that must be met, such as sufficient access for inspection during use, repairs, or maintenance.
* Major Costs: These include the initial purchase, maintenance (such as cleaning or replacing filters and parts), and operation (such as electricity).
* Odors: Air cleaning devices designed for particle removal are incapable of controlling gases and some odors. The odor and many of the carcinogenic gas-phase pollutants from tobacco smoke will still remain.
* Soiling of Walls and Other Surfaces: Ion generators generally are not designed to remove the charged particles that they generate from the air. These charged particles may deposit on room surfaces, soiling walls and other surfaces.
* Noise: Noise may be a problem with portable air cleaners containing a fan. Portable air cleaners without a fan are typically much less effective than units with a fan.

One of the most important things to maintain on your new cooling unit is the air conditioner filter. Dirt and debris in the filter will reduce the air flow and thus the effectiveness of your conditioning unit. Once your air conditioners filtering unit becomes very clogged with dirt and debris, those dirt particles will bypass the filter and start messing up the air quality along with the machines working parts.
While some air conditioner filters can be cleaned and reused, some need to be replaced altogether. If the filter on your cooling system can be replaced, it should be done or at least checked every month or two. Just like in any machine, the frequency that you change your air conditioning filters depends on the external operating conditions. Dusty environments combined with heavy use will speed up the need for a cleaning or replacement of your systems filters.
Traditionally most simple air conditioning unit filters were made from foam, fiberglass or another washable screen type material. These air conditioner filters collect particles via a sticky surface of oil or similar substance. One draw back with foam units is that there is a risk of small foam particles mixing into the expelled air. The second is that foam air conditioner filters wear out quicker than some more modern conditioning unit filter types.
The newest type of air conditioner filter is the electrostatic mesh. Electrostatic filters are neat in the way that they filter air compared to the old “sticky grab” method. The movement of air across the air conditioners synthetic weave of fibers creates a static charge that collects the dust on the filters surface. A side benefit to this electric charge on the filters surface is that is creates ozone which helps to kill bacteria and unpleasant odors.
You should change your air conditioner filters at regular intervals because when your filter is new, it grabs up to 10% of the dust and particles that cross over its oil filmed surface. As time passes more dust gets trapped in the filter, which is a good thing, but all those extra particles will cause less air flow to get through. By keeping your conditioning unit inspected and maintained at regular intervals will not only save you money in electric bills and repairs but also keep you air quality supremely conditioned.
What is the best make of air conditioner filter? As with all types of consumer products, there will varying opinions and lots of marketing to deal with. Often when trying to find a new product the best thing to do is ask the opinion of others. Air conditioner filters are no different. There are several websites and forums where you can go and look through the consumer reviews and make a better decision as to what air conditioner filter would best suit your needs.

You have possibly heard in the news, read on the internet or news paper that the air we need to sustain our planet is getting worse. Did you see China before the olympics? Everyone wearing face mask, beacause just by being outdoors they were exposed to pollution so potent that it was equal to smoking 3 packs of cigarettes a day. What about the air in side homes in China? Do you think that the people there are wearing masks indoors? The pollution problem is not only Chinas, but the worlds problem. With trees are being cut the deforestation is going to affect all of us. The population is growing which of course leads to the addition of more automobiles on the road, and massive factories to produce all the wares the population demands. The air is starting to become extraordinarily polluted, and the clean air and clean water we take for granted everyday, may soon be unbreathable. The solution to the worlds pollution is going to global efforts from government, and citezens around the world. We can do our part to help keep our plant clean, and we can also keep ourselves healthier by keeping our indoor air in our homes clean. Pollutants in the home that can also cause acute respiratory problems, and luckly many can be prevented with proper maintance of your homes air filters.
Do you think your home air is cleaner than the air outside?
Think again……. no, the air within your house is up to ten times more polluted than the air outside. The reason behind this is the air within your place has no way to get circulated around and so the air get obstructed with all kinds of chemicals and dust. Since the majority spend up to ninety percent of their time inside this could be a major problem.
The air circulating within your home if full of dust, smoke, pollen, animal dander, tobacco smoke, particles generated from combustion appliances such as cooking stoves, and particles associated with tiny organisms such as dust mites, molds, bacteria, and viruses. Other items that can pollute your indoor air are from chemicals such as household cleaning items, but indoor pollutants can also come from sources like your fireplace, leaky gas stoves or radon an invisible gas that is trapped inside your home. It can come up from the ground, and it is undetectable, but it can cause breathing problems and cancer. If you suffer fromh asthma, enphasema, or any other respitory problems you may already be affected by the invisible pollutants in your home. With all these pollutants floating around, many invisable to the naked eye, you may not realize how toxic the air in your home is. If you have a chronic cough, runny nose, itchy eys, you may want to check your home for unseen pollutants. The long term affects of breathing polluted indoor air, can take many years to materialize, but if you live in area of the country that has a high pollution index outside as well, you may feel the affects much sooner.
You may not have many options for when you are outside, but when you are in your home, you can use air conditioner filters and furnace filters that remove dust, pollen, allergens, smoke and other particles from the air so your family can breathe easy. Change them on a regular basis, the little extra time and money you spend now may pay you back many times over, as you will be healthier, and spend less money on doctor bills and medications.
Indoor air pollution Background on the public-health impacts of indoor air pollution.
Indoor Air Pollution Fact Sheet Poor indoor air quality can cause or contribute to the development of chronic respiratory diseases such as asthma and hypersensitivity pneumonitis.
One of the most typical health issues that plague our society is dehydration.
The majority of the tissue in the body is made of water. If it loses the water, the tissue dries up.
It’s elasticity goes, and with it function declines.
Conditioning the quantity of moisture in the air with a furnace humidifier is need for your health. Dry air in your house can make your throat feel dry, and cause or irritate respiratory illnesses. The heating seasons causes folk to start having repeated attacks of winter colds.
Essentially, for many dry air is an air-quality issue. How will a furnace humidifier have effects on your comfort? Humidity in the home will have effects on your comfort. By giving up moisture to the air, your skin, throat and nasal passages dry out and crack leading to numerous physical pain. Nearly everything in your house made of wood contains some moisture. As dry air sucks that moisture out, the wood shrinks and cracks. Hardwood floors separate at the seams, furniture shrinks and cracks, and doorways warp and no longer fit their frames as the moisture is drawn off. Also, maybe the most irritating effect of dry indoor air is static shock. How often have you shuffled across the carpet, only to be insultingly stunned by the crackle of static as you reach for the light switch. It’s no fun when it happens to you, and even less so when you reach out and "zap" a friend or family member. With the capacity to grip a static charge up to twenty thousand volts, your body can also do serious damage to home PCs and other sensitive electronic devices. By maintaining indoor relative humidity at 35 % or higher with the application of a humidifier, static shocks are seriously reduced.
Are there any other advantages to installing a furnace humidifier in the home? Warm, humid summer air feels warmer than it essentially is due to the moisture it contains. That same principle is applicable to your house in the wintertime. By keeping the relative humidity within your house at the ultimate level, you can turn your thermostat down some degrees and still feel cosy. Dialing down your thermostat just three degrees can scale back your heating bill by as much as 5%.

The future is here as some heating companies have abandoned servicing oil furnaces because their liability insurance rates had increased substantially, and the quantity of oil furnaces was declining. If you live out in the country, natural gas is probably not available. The option open when you live rurally is to have a propane company install a tank. They will install the tank and supply line for almost nothing, and then regularly give large rebates on your first fill up.
Many years ago, oil was the fuel of choice for people who didn’t have natural gas service; however oil is not a clean burning fuel. If you have an old oil furnace, and you are thinking of switching to gas does yourself a favor; you might remove the back access panel on the oil furnace, and look at quantity of soot in the heat exchanger. You might be surprised at what you find. Take a look at the bottom one-third of the passageways; are they blocked by what looks like yellow bricks? If so, that is actually blocks of sulfur.
Furnaces from as recently as 20 years ago may offer half of the heat production of today’s more energy efficient models, while releasing significantly more harmful gasses into the atmosphere. You will find that natural gas furnaces emit very little gas making the need for a chimneys are a thing of the past. You can pipe from the basement to the outside as narrow as eight inches is enough for a natural gas furnace to work efficiently. However, with an oil furnace, their exhaust fumes must be heated to a higher temperature in order to rise and escape and this requires that flues be at least 18 inches wide to release harmful gasses properly.
Efficiency
Fuel oil has very high sulfur content. It has been stated that the sulfur content is around 3,000 parts per million, which would be 0.3%. For an impurity, that is a very high concentration. For an impurity, that may be an extremely high concentration. The Gas furnaces runs about 94.1% to 97.0% Efficient and compared to oil burn extremely clean Carbon monoxide levels are extremely low around 18-20 ppm (acceptable levels are anything below 75ppm) if they are properly installed.
Maintenance
Another question is do you as the home-owner want to deal with accumulated sulfur and soot removal with a yearly furnace cleaning? With an oil furnace an once a year cleaning and service call is really obligatory, as the soot must be removed from the heat exchanger. Also, the oil spray nozzle should to be replaced and the air-fuel ratio adjusted to reduce soot buildup. When the soot builds up, it begins to restrict the flow of combustion gases. If this gets bad enough, it could cause the furnace to stop working, or worse, can send combustion or noxious gases into the house.
Gas and propane furnaces do not have the same maintenance needs as oil furnaces. Gas and propane units need the air filter to be replaced monthly, and it’s a good idea to vacuum the dust off the blower every year, but you may find that gas and propane burners can get a small amount of soot buildup, but they can go 10 or 20 years with nothing more than a wisp of ash. The up keep cost on a gas or propane furnace is going to be lower than an oil furnace in you compare the maintenance costs. The maintenance on an oil burner alone could boost your heating costs if it’s done every heating season as recommended.
Furnaces manufactured after 1992 in the U S are required to have AFUE ratings of 78% or more, most furnace models today exceed these minimums. While both oil and natural gas furnaces can now provide significantly more heating power than they could earlier, technological limitations prevent oil furnaces from being able to reach the AFUE scores in the high 90% range that some natural gas furnaces already have. For every percentage point higher the AFUE rating is, the more money you will save over the life of the furnace.
Electric Furnaces
Natural gas is not only considered a clean-burning fossil fuel, but it’s also more efficient than electricity when used for household heating.
Switching from gas to electricity would run counter to many state’s energy efficiency goals because using electricity for heating is about 2 1/2 times less energy efficient than using natural gas, according to Neal Elliott, associate research director at the American Council for an Energy Efficient Economy, a Washington nonprofit that promotes efficiency.
"The bottom line for use is fuel switching," said Angela Townsend, spokeswoman for PSNC. "If the ultimate goal is to truly promote energy efficiency, an incentive program wouldn’t allow customers to switch over to electricity." It seems buying or replacing an old furnace, the gas furnace is still the better fuel efficient option.
Upgrade
Upgrading your heating equipment to natural gas will save money you money in the long haul. Making the decision to have a high-efficiency gas furnace installed will provide you with quieter and cleaner burning unit. Since a gallon of liquid propane has less energy than fuel oil (about 92,000 BTUs versus about 130,000 BTUs for oil) the actual annual heating cost may be slightly higher than with fuel oil, but the maintenance costs may even it out. Your home air will be cleaner, and you will not have to smell laden air in your home, which your lungs may thank you for later. Read up indoor air pollution here.

HVAC (heating, ventilation, air condtioning unit) Geothermal heat pumps provide the most earth-friendly home heating and cooling system available. Installing a geothermal heatpump system, you’re investing in a naural heating souce that will uses less energy, provide for our childens future as it keeps the air clean and fresh. It emits zero pollutants, in your home, and provides cost effecting heating.
During the heating season, according to EEER ( gov energy ) a ground-source heat pump supplies three to four units of heat to your home for every unit of electrical energy required to operate the system. So you get two to three kilowatt hours (kWh) of free energy for every one kWh of electrical energy you pay for. In other words, a ground-source heat pump is 300% to 400% efficient.
Don’t forget the tax incentives when you install a geothermal heat pump system.
Geothermal heat pumps are like standard heat pumps, but use the ground rather than outside air to provide heating, air conditioning and, often hot water.
As they use the earth’s natural heat, they are among the most productive and comfortable heating and cooling technologies now available.
Energy star geothermal heat pumps state that ENERGY STAR qualified geothermal heat pumps use about 30% less energy than a standard heat pump.
They are quieter than conventional systems. Very reliable 95-98%
In the winter the normal heat pump system extracts heat from outdoor air and transfers it inside where it is circulated through your home’s ductwork by a fan.
Even cold air contains a great deal of heat; the temperature at which air no longer carries any heat is well below -200 degrees Fahrenheit. That is not too common an occurace.
How Does Geothermal Energy Work?
How does geothermal energy work is a good question, and one which I have often been asked. In this article I must first explain what it is, and then how it can be made to work for man.
Geothermal energy is, literally, the heat of the earth. The heat itself derives from radioactive decay beneath the earth’s surface and, in certain locations, it is concentrated enough and is close enough to surface waters to be brought to the surface by local geological features.
Geo-energy was once thought of as nothing but a thing to wonder at, but it is thought of very differently, now, and is considered by many as one of the most promising forms of renewable energy. It is a renewable energy source because the hot water which conveys it is replenished by rainfall and the heat it brings with it is continuously produced inside the earth.
The great thing about it is that as a form of energy it is versatile and reliable and it produces electricity which generally produces none of the greenhouse gases associated with the combustion of fossil fuels.
So, geothermal energy is the power which can be generated by the harnessing of the heat beneath the Earth’s surface. Deep wells are usually used to pipe steam and hot water from deep within the Earth, up to the surface.
Geothermal heat comes from the magma in the earth’s core, and that itself is heated by the radioactive decay of uranium, thorium, and potassium present in the core. Geothermal energy is present everywhere beneath the Earth’s surface, although the highest temperature, and thus the most desirable, resources are concentrated in regions of active or geologically young volcanoes.
Though the resource is thermal energy rather than a physical substance such as gold or coal, many aspects of geothermal energy are analogous to characteristics of mineral and fossil-fuel resources.
Geothermal energy works for us when, for example, is used as to warm the water in fishing farms. The water is heated, and the warmth makes it more possible for alligators, tropical fish, and other types of fish to grow in seasons and places where they wouldn’t normally.
There are some limitations to it as a form of energy. Unfortunately, the best geothermal resources are concentrated in areas of volcanic activity and are not widely distributed. The earth’s centre is a distance of approximately 4000 miles from the surface and is so hot that it is molten, but when the heat does not rise to the surface it is too far to drill down to the center.
When used in a power station geothermal heat from the hot water from the well causes a ‘secondary fluid’ to turn into vapor, which as it expands drives the turbines to produce electricity. Since the technology used in a binary-cycle geothermal power plant is a closed-loop system, nothing is emitted to the atmosphere. After turning the turbine generator, the working fluid is condensed back into liquid, which is repeatedly vaporized by the geothermal heat in a continuing cycle.
Dry steam and flash steam power plants do emit low levels of carbon dioxide, nitric oxide, and sulfur, although reportedly at only roughly 5% of the levels emitted by fossil fuel power plants. However, geothermal plants can be built with emissions-controlling systems that can inject these substances back into the earth, thereby reducing carbon emissions reportedly to less than 0.1% of those from fossil fuel power plants.
Dry steam plants are used when the rock is very hot. They take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator. Flash plants take hot water, usually under pressure and at temperatures over twice the normal boiling point of water, out of the ground. They allow it to boil as it rises to the surface then separates the steam phase in steam/water separators and then run the steam through a turbine. The turbine also turns a generator, and from that comes the electrical power.
Temperatures in the Central Texas hydrothermal aquifers range from about 90 degrees Fahrenheit to 160 degrees F at depths from 500 to 5,000 feet. Historically these waters have seen some application in spas and therapeutic baths, but might also be developed for geothermal winter heating if used with heat pumps.
If you were to ask the average Icelander; ‘How Does Geothermal Energy Work’. He would probably say; ‘very reliably’ and, ‘our country shows how it can work very well’.
Iceland takes advantage of its incredible geological structure to use geothermal power to their advantage. Recently, it has been reported that 17% of Iceland’s total electricity production comes from geothermal energy. Iceland has reached uniquely high levels in the utilization of geothermal energy, but the resource could be better utilized globally. Iceland is very lucky when it comes to energy as it gets almost all of the rest of its electricity from Hydro-power dams.
Energy from geothermal sources today has been said to amount to less than 0.1 percent of the global world use.
Currently in the US, the author understands that, only four states generate electricity from geothermal resources. In total, this provides electricity for about 3.7 million people.
HVAC Discover the Benefits Of Geothermal Heat Pumps
Discovering the benefits of geothermal heatpump systems , is very exiting to anyone who is looking for to lower their utility bill, have a clean source of energy, and is environmentally conscience. Geothermal heat pumps tap into the earth just a few feet underground, to produce clean efficient energy that is completely under utilized. Geotheramal heat pumps are reliable, and unlike oil we will never run out of it.
The Benefits Of Geothermal Heat Pumps
A Geothermal Heat Pump (GHP) is an apparatus that extracts heat from below the surface of earth. It works on the principle that heat flows from higher temperature substances to lower temperature substances via conduction or via convection (air currents). Geothermal Heat Pumps take in heat from the earth or water bodies to provide space and water heating. This works since the earth traps nearly half the sun’s energy that is received by the earth.
Ground source heating and cooling will give great comfort and be cost-effective with environmentally-friendly technology which uses our planet’s ability to store energy as heat. Geothermal heat pump systems move the heat from Earth or from water into buildings, or from buildings right back into Earth. A little bit of electricity is employed for operating fans, pumps, controls, and a little compressor.
GHPs utilize the relatively constant temperature of the ground or water several feet below the surface as a source of heating and cooling and are appropriate for both retrofit or new homes. In addition to space heating and cooling, geothermal heat pumps can provide hot water with virtually no additional energy requirements because GHPs don’t create heat; they merely move it from one area to another.
This is a relatively new technology that can save homeowners money
Although the initial cost of a new geothermal system is generally more expensive than a traditional heating and cooling system, the extra investment is returned within five to ten years. The ground loop piping is estimated to last over fifty years, and even the internal parts have about a 25 year life span. Every year about 50,000 new geothermal heating systems are added in the United States. They’re very reasonable for most areas and can use the Earth for heating when temperatures drop and as a heat sink when it’s hot outside.
Quite a number of new residential systems come with desuperheaters, by which excess heat is transferred to the home’s hot water storage tank from the geothermal heat pump’s compressor, providing a highly efficient means of heating water. But in the spring and autumn, during which the geothermal heat pump system does not operate, the desuperheater will not provide hot water. However, because of the geothermal system’s significant advantage in efficiency compared to other water heating methods, ‘full demand’ systems using a separate heat exchanger to meet hot water needs cost-effectively are now being offered by some manufacturers.
Even though the cost of installation of Geothermal Heating Systems can be several times that of traditional heating and cooling systems, the additional costs are returned in energy savings in 5 to 10 years. This is because of the very high efficiency of Geothermal Heat Pumps .
Staying warm is important to all of us, so when we go about choosing the right heating system is pretty significant.
Selecting the fuel and heating system best suited for your needs will probably depend greatly on what area of the country and you live in. Fuel rates vary considerably by utility service area, geographic location and/or season, it is important to know your own local rates when comparing your heating system options.
Installing a new heating systemwill be less taxing, and there are some great new energy efficient models available. However when you are replacing a heating system you also have to take into consideration the age and how well maintained it is.
How well insulated is your home? Before you install your new heating system fortify the insulation in your home, calk around the window, or you’re will be losing heat, and throwing any money and energy savings literally out the window.

Heating Systems: A Quick Comparison
Heating systems come in many different forms and configurations. When choosing one for your home, it is critical that you take several factors into account: efficiency, cost, capability and maintenance. The following is a quick overview to give you some options when planning to purchase or reinstall your current heating system.
Forced Air
Forced air is the most commonplace heating system in place, especially in new construction in most parts of the country. Forced Air Heating heats air through a standard furnace using natural gas, propane, oil or electricity.
The heated air is then pushed through ductwork throughout the house by a circulating fan.
The main advantages to this type of heating system are many. The furnace, depending on size and energy source can create the highest efficiency for certain types of homes.
The unit also can accommodate a dual purpose in that it can also serve as the central source for air conditioning and ventilation as well – the only one of these heating systems that can do so. Forced air can also integrate such add-ons as filtration and humidification units.
Forced air systems can, however, have some drawbacks. The units generally require more maintenance than others. They also require an extensive system of ducts in even small homes. Ducts can take up space, alter designs and can be difficult to reach to clean and service. For small to medium homes, these units generally provide the highest efficiency at the lowest cost.
Radiant Heat
One of the most popular new systems is radiant or ambient heat. Generally, it can come in the form of a hot water tube embedded in a floor or wall – although a radiant heating system can also refer to wood or coal stoves, fireplaces or other fuel-burning heating systems placed in the open. The advantages to radiant heat are many, but so are the disadvantages. In the case of tubing laid in the floor or wall, the heat is uniform and consistent throughout the home. Architectural design is not affected as it is an "invisible" heat source, allowing for wide design choices. However, if repairs are needed, the system poses severe problems with access and potential structural upheaval.
The heating cycle is slow, as well, so it is not recommended for spaces with rapid, repeating and extreme temperature changes. Ambient heat does not offer a ventilation or air conditioning option at all. Ambient heat offers a high installation cost and a potentially very high repair cost. But the boiler heating the system, if chosen wisely, can offer a very high efficiency factor.
Hot Water Radiant
Usually knows as "hot water baseboard" heating systems, this heating option pushes hot water through tubing (usually copper) installed at the bottom of each room’s walls. The heat is circulated purely through convection, meaning that no ventilation or circulating device is needed, making the system very quiet.
While the system offers high efficiency at low installation cost, the structure can impede certain designs in homes. Repair is not usually a consideration. As with ambient or radiant heat, the choice of the boiler usually determines the efficiency of this particular style of home heating system.
Again, a separate air conditioning and ventilation unit is required.
Steam Radiant
Similar to hot water radiant, steam radiant uses a series of pipes or tubes to warm the home through convection. While the system is still in use in some older construction and in some European homes, this system is not used much in the United States.
Also similar to water radiant, the system can be very efficient when the proper type of boiler is used and powered by an appropriate fuel source which may include propane, oil, electricity or alternate energy. An air conditioning and ventilation system would be a separate system entirely.
Geothermal Heat Pumps
Geothermal Heat Pumps (GHPs) are unlike either Forced Air or Radiant heat entirely – and are perhaps the most exciting new technology offered in home heating systems. The concept of a GHP is to take heat or cold and to displace it by using long pipes running into the ground. Since the ground at the buried depth is normally a fairly consistent (and comfortable) temperature, the heat or cold is displaced, returning a comfortable temperature to the home.
The advantages are enormous efficiencies and savings – in the range of upwards of 70% over other heating or cooling sources. However, the cost and construction can be prohibitive to achieve these efficiencies. Certain home sites may not be able to take advantage of this system, and maintenance can be extremely high.
Which is Right For You?
Each system does offer advantages and disadvantages to each potential homeowner. Taking these all into consideration, particularly selection, maintenance and repair, as well as response time for service or an emergency should all be taken into consideration.
The season seem to change quickly, and soon as we prepare for winter, summer is here, and we have switch our thinking from heating to cooling our home.
Changing filters is the first must do, and it is simple enough to do it yourself. Updating your air conditioners, replacing older models with newer more efficient models can make a large impact on your utility bills. If you are not going to install a simple A/C window unit, and a central air conditioning is what is needed in our home, it is best to hire a local contractor who can size and install your air conditioner properly.
Tips:
Don’t try and fluctuate the temperature between different rooms in your home by closing channel outlets or you will unbalance the system and reduce its efficiency, and may cause your unit to work harder, and increasing your costs. When you’re away for many hours, turn the unit off. Keep the thermostat at 78 degrees in the summertime, a cushty temperature for most of us. Each degree of temperature ends up in a 4 p.c increase or decrease in your application bill.
Air leaks are a major source of energy inefficiency. If a $1 bill slips easily thru the opening around your doorway, you are losing valuable cool air and letting heat in.
Check with your local power company to see if they off rebate programs for updating, and replacing old air conditioners, furnaces, heat pumps, water heaters. and so forth with new energy efficient models.
With temperatures rising and cooling systems running for longer periods of time, it’s the ideal time to take control of your electric bills.
Set your thermostat on the highest comfortable setting. If you’re leaving for the day, turn it up a couple of degrees. Do not turn your cooling system off unless you’ll be gone for an extended period of time.
Clean or change your filters monthly. Dirty filters can increase operating costs by 20 percent. Don’t block registers and return vents with furniture or drapes.
Use a ceiling fan or portable fan to supplement your air conditioning. A fan can make you feel three to four degrees cooler (and only costs a half-cent per hour to operate) so you can set your thermostat a few degrees higher and save on cooling costs. Use in occupied rooms since fans cool people, not rooms. As a safety precaution, turn off ceiling fans when you leave your home.
For central air conditioning systems, keep the fan switch on your thermostat in the "auto" position when cooling. This gives you better cooling and humidity control. Having the fan switch "on" continuously could cost $25 extra a month on your electric bill.
Close blinds, drapes and shades during the hottest part of the day. This keeps the sun’s rays from heating your house.
If you suspect your air conditioning system is not cooling properly, have it checked promptly. A unit that is having operational problems can cause extremely high bills.
If your air conditioning equipment is older and less efficient, compensate by being extra careful about temperature settings, hours of operation and filter condition.
Use your microwave or countertop appliances for cooking instead of the oven or stove.
Make sure your home is properly insulated. In existing homes, wall insulation may be too expensive to install, so concentrate on attic and floor insulation.
In Carolina:
Ceiling: R-30
Wall: R-11 to R-19 in frame wall
Floor: R-19 in floors
What Is R-30 it a reference numer on the insulation value given to insulationg material.
Insulation is rated by thermal resistance, called R-value, which indicates the resistance to warm flow. The bigger the R-value, the bigger the insulating effectiveness. The R-value of thermal insulation relies on the kind of material, its thickness, and density. In working out the R-value of a multi-layered installation, the R-values of the individual layers are added. Installing more insulation in your house increases R-value and the resistance to heat flow.
The usefulness of an insulated wall or ceiling also relies on where the insulation is installed. As an example, insulation which is compressed won’t give you its full rated R-value. Also, the R-value of a wall or ceiling will be rather different from the R-value of the insulation itself because some heat flows round the insulation thru the studs and rafters. With careful design, this short-circuiting can be reduced.
Preparing your home for summer can help make your home more comfortable, and can save you money that will stay in your pocket, and not the utility companies coffers.
HVAC -To Heat Pump or Not to Heat Pump That Is the Question?
If you are thinking of installing a HVAC system in your new construction you would be wise to do a little research. Heat pumps have many great features that can add value and comfort to your new home.
To Heat Pump Or Not To Heat Pump?
Well, that is a great question. Anytime you are going to shell out a big chunk of money it is a good idea to get bids, and increase your knowledge base. That way you will not be kicking your self later when you find out the unit is oversized, undersized, or installed wrong.
What Is a Heat Pump?
Heating and air-conditioning systems control the temperature, humidity, and the total air quality in residential, commercial, industrial, and other buildings. You can find more information on how heat pumps work on my HVAC system page.
Create a list of questions to ask your local contractors, or home building store staff…
Is A Heat Pump Right For Your Home?
Comfort is a big consideration in any household. It makes the house a more comfortable place to live in. It makes a house a home. This is also a reason why you must take proper considerations of the necessary changes that can be implemented in the house, changes that will improve the present conditions.
One of the questions that most household dwell on is whether or not to install a heat system in the house. Of course, the comfort and safety of the family must always be the priority. Of course, deciding on the heat system also entails certain consequences that the household must prepare for.
The heating system, as the name implies, ensures the comfort of the family when the weather gets too cold. Of course, most heating systems, when not properly installed or cared for will end up as a liability. That is why one must pick the right heating system to support the needs of the family.
Is a Heat Pump the Right System for Your Home?
The heat pump system depends on the magic of obtaining heat from the cold air and processing it to be supplied to the house. This mechanism makes use of the heat pump appliance that operates on a refrigeration technology. With this at hand, instant warmth and cooling can be easily secured.
Many households have benefited and attested to the goodness entailed by installing heat pumps. There are many ways to make heat pumps an ideal companion during the cold climate.
1. Good Alternative
The heat pump is a good tool for places where electrical heat system is the only option. Not every location can get a good source of natural gas to support the traditional conditioning system. This may dispense with the electrical system. Of course, it all depends on the environment.
$$
2. Save Energy and Save Money
The heat pump is also a bestseller for its energy saving attributes. The installation procedure may take some expenses. Of course, after the installation stage, the rest comes easily.
A heat pump will produce twice amount of heat with just the same amount of energy that an ordinary and less expensive electric heating system will provide. Thus, it necessarily follows that one get to save more money in the process.
3. Consider the Condition of the House
The heat pump can also work best in a household constructed with the proper insulation. There are also energy-efficient elements that can be built in the house.
These aspects shall ensure that with just one heat pump the whole house can enjoy the warmth. These can also facilitate the heat pump to work efficiently at all times, no matter how much the weather outdoor will change or drop.
4. Size and Installation
The right heat pump must be properly chosen according to its size, whether it is to serve a cooling or heating purpose. Ascertain these aspects upon installation.
5. Length of Use
There are heat pumps ideal only for short term utilization. Some can withstand lengthy usage. In general, an air-source heat pump is not to be used over long periods and below zero temperatures. Thus, this should be considered properly with the location of the house and demands of the family members.
6. Ground Source Heat Pumps
Ground source heat pumps or GSHPs are the more effective kind. They may require more expenses for installation. Of course, they become beneficial in the long run. They can last long. They can also help the household save more money.
7. Sound Levels
Most people are discouraged of heat pumps because of the noise aspect. There is, however, an alternative to get rid of this problem.
Choose the right heat pump by buying the ones that have sound levels of, at the most, 7. 6 bels. This indicates the noise level of the outdoor pump. It is better to find sound ratings lower than 7. 6 bels.
HAVC Best Thermostat Settings to Save Energy In the Winter
Thermostat Settings to Save Energy In the Winter
What are the best settings to save energy and cut your heating costs? Well, According to
Progress energy here are some tips that will help you do just that…..
Winter
With winter temperatures falling and heating systems running for longer periods of time, it’s the ideal time to take control of your electric bills.
Keep your thermostat at the lowest comfortable setting. If you have a heat pump, adjust your thermostat in small increments to avoid the operation of the supplemental heat strip in your system. Energy consumption is much higher when the heat strip is in use. A steady setting on your heat pump thermostat produces constant comfort and minimizes the use of the less efficient resistance heat strip.
Keep the fan on your central heating unit on “auto” position. Leaving the fan on “on” can add $25 a month to your heating costs.
Install the heating thermostat on an inside wall and away from windows and doors.
Clean or replace filters every month. Dirty filters can increase operating costs by 20 percent.
By setting your thermostat back 10 degrees at night (8-10 hours), you’ll save 10 percent to 20 percent in heating costs. The lowered thermostat setting saves energy dollars by reducing the length of time the heating system operates throughout the night.
Use ceiling fans in winter to distribute heat around a room.
Close your fireplace damper when not in use. Consider glass doors to help prevent heat loss when your heating system is on.
Make sure registers are not blocked by furniture or draperies.
Use insulated or heavy curtains on windows facing the north side of the house. Keep curtains and shades closed at night or on cloudy days.
When entertaining, lower the thermostat a degree or two before the guests arrive. That way, you won’t overheat.
Older thermostats are ineffective as they operate at one setting all day 24×7. You are able to save on your use bills by installing a programmable thermostat that enables you to ascertain what times of day your heater or air conditioner will operate.
Saving on energy cost is just one of the many benefits for switching to an electronic programmable thermostat for controlling your heating and cooling system.
You can save around 10% a year on your heating and cooling bills by simply turning your thermostat back 10-15 degrees for 8 hours. You can do this mechanically without sacrificing comfort by installing an automatic problem or programmable thermostat. Do this when you will be out of the house at work, school, or other functions that take you away from your home. Your pocket book will thank you, and you will not have to sacrifice your own comfort.
High homeowner utility bills can be attributed to homeowners who fiddle with the thermostat. Find your comfort zone, program it, and then forget it.
Programmable thermostats can store and repeat multiple daily settings that you can manually override without inspiring the remainder of the daily or weekly program. When purchasing a programmable thermostat, look for the ENERGY STAR label if you enjoy saving money and being environmentally consciences.
Timers make this a very easy task to master. In the end you will find this will save you considerable amount of money by operating your air conditioner and heating system only when it’s needed.
Before you go out to buy a new programmable thermostat have a look at the one you have on the wall.
If your old thermostat is connected to thin wires coming at once out of the wall, it has low-voltage wires, which don’t present a shock danger. But if the thermostat is wired into an electric box, then it’s doubtless running off 120-volt current. Don’t attempt to replace it till you’ve consulted with an approved electrician.
If you are replacing a thermostat that contains mercury in a sealed tube, don’t throw it out with the household trash. It is important to go online or contact your local waste management agency for instructions for the proper disposal. We only have one earth, and it’s a little thing, so do your part to keep it clean.
Getting Started:
Common material your install may require different tools:
You Will Need To Gather Your Materials And Follow The Instructions On The Video:
One or two standard screwdrivers Drill and drill bit Ruler and level Screws and dry-wall anchors Programmable thermostat
WARNING
Installing a new programmable thermostat is pretty simple, but use your own judgments on whether you have the proper skills to perform this task. When installing anything that involves electricity, it is always a good idea to hire a professional if; you do not know how to cut your electricity, use a drill or handle electrical wiring. Please take into account that the few dollars your might save doing it yourself is not worth risking your life!
Hvac – an acronym for Heating, Ventilation & Air- Conditioning
Heating and air-conditioning systems control the temperature, humidity, and the total air quality in residential, commercial, industrial, and other buildings. Heat pumps, which are similar to air conditioners but can be reversed providing both heating and cooling for a home. Heat pumps uses mechanical energy to pump heat “up the temperature scale” from a cooler region to a warmer one, and it does this by changing the pressure of a working fluid called a refrigerant. Heat pumps are more complex, and because they run in both summer and winter, they often require more maintenance and need to be replaced more frequently than traditional furnaces and air condition
Heat Pumps Fall Under Different Categories Such As:
Individuals that specialize in heating, air-conditioning, and refrigeration, and they go by the terms technicians, mechanics and installers. They install, maintain, and repair systems. Heating, ventilation, air-conditioning, and refrigeration systems many times referred to as HVACR systems, these repair technicians may also be called HVACR technicians. Properly trained technicians repair, and maintain systems, but you will find that many have elected to specialize in installation, maintenance & repair, heating systems, refrigeration care, or air conditioning. Finding a technician who specializes is a brand or special equipment type is another great way to locate the right technician for the job. It always a good idea to find a technician that is familiar with our brand or type of system.
What Are the Component Units? Heating, air-conditioning, heat pumps, geothermal heat pumps and refrigeration systems are a dizzying mix of many mechanical, electrical, and electronic components. These include components such as motors, compressors, pumps, fans, ducts, pipes, thermostats, 4-way reversing valve, bi-directional expansion valve, thermal expansion valve or " TEV ", air conditioner compressor ,condensing coil, air filters, refrigerants, room thermostat, electrical switches, fuses or circuit breakers, blower fan, numerous switches, and more.
Air Conditions Systems how do they Work?
Air conditioning or heat pump compressor which compresses low pressure refrigerant gas into a higher pressure, higher temperature gas. Usually the compressor is in the outdoor portion of an air conditioning or heat pump system. The compressor is basically a high pressure pump driven by an electric motor A condenser or condensing unit: typically a condensing coil inside which high temperature high pressure refrigerant gas flows, and over which a fan blows air to cool the refrigerant gas returning it back into a liquid state (this transfers heat from the refrigerant gas to the air being blown by the fan).
A metering device which dispenses liquid refrigerant into a evaporator coil. The metering device may be basically a thin section of tubing (a capillary or "cap" tube) or it may be a bit more sophisticated thermostatic expansion valve (TEV ) which includes a temperature sensing control that can open and shut the device against refrigerant flow an evaporator coil or cooling coil: usually the cooling coil is a section of finned into which liquid refrigerant is metered and permitted to evaporate from liquid to gas state inside the coil.
An air handler and blower unit which provides a fan, that blows building air across or through the evaporator coil. The air handler blower fan unit moves building air across the evaporator coil surface in order to condition building air by cooling it (this removes moisture from the cooler air).A duct system which sends conditioned air from the air handler into the supply ducts, and which then takes air from the ducts and returns it to the cooling system air handler.
Controls and features , which include a room thermostat, electrical switches, fuses or circuit breakers, condensate handling system, and air, filters.
How Do Forced Air Heating Systems Work? When a technician installs a central forced air heating systems it works like this, a furnace heats the air, which is then, circulated via a system of metal or fiberglass ducts. Technicians must be able to maintain, diagnose, and correct problems throughout the entire system. To do this, they adjust system controls to recommended settings and test the performance of the system using special tools and test equipment. After a furnace or air-conditioning unit has been installed, technicians often asked to perform routine maintenance and repair work to keep the systems operating efficiently. Technicians may adjust burners and blowers and test for leaks. If the system is not operating correctly, they test the thermostat, burner nozzles, controls or other parts to diagnose and correct the problem as needed. During the winter heating season, air-source heat pumps cease to be effective when the outside air temperature falls below 25-35°F. To handle such conditions, they are supplied with a supplemental heating system – usually electric resistance strips to further warm the building supply air after it leaves the indoor coil. You will find that you need to hire technicians or perform the maintenance work yourself, such as replacing air filters, inspecting cleaning ducts, overhauling compressors, and maintaining other parts of the system that may accumulate dust, mold or other impurities during the operating seasons.
How Does a System Get Installed?
They follow blueprints, design specifications, and manufacturers’ instructions to install motors, compressors, condensing units, evaporators, piping, and other components. They connect this equipment to the ductwork, refrigerant lines, and electrical power source. After putting the equipment in place, they install fuel and water supply lines, air ducts and vents, pumps, damper control switches, and other components . They may connect electrical wiring and controls and check the unit for proper operation. To ensure the proper functioning of the system, furnace installers often use combustion test equipment, such as carbon dioxide testers, carbon monoxide testers, combustion analyzers, and oxygen testers. These tests ensure that the system will operate safely and at the highest level of efficiency. After making the connections, they charge the system with refrigerant, check it for proper operation and leaks, and program control systems. You will find that heating, air-conditioning, and refrigeration mechanics/technicians, and installers use a variety of tools, including hammers, wrenches, metal snips, electric drills, pipe cutters and benders, measurement gauges, and acetylene torches, to work with refrigerant lines and air ducts. They use voltmeters, thermometers, pressure gauges, manometers, and other testing devices to check airflow, refrigerant pressure, electrical circuits, burners, and other components. It is possible to fix small components yourself, but if you do not have many of these tools, you may be hard pressed to do the job correctly yourself.
Can I Buy My Own Replacement Parts? Yes, if you can find the parts yourself, you can save some of the mark up price many installation companies tack on. Don’t be timid about requesting a price for parts & service, and another price for service alone. You might be surprised on the mark up some companies charge on comparable items.Commercial HVAC systems.
