Troubleshooting Heat Pumps Problems

Is your heat pump in a need for repair? Are you facing heat pump problems? If yes, then go through this article to understand the tips for troubleshooting heat pumps.

Heat Pump Problems : troubleshooting heat pumps
Heat pumps are the mechanical devices that are configured for transferring heat from one location ( source ) to another ( sink ). In the majority of the cases, heat pumps draw heat either from the atmospheric air or from under the Earth’s surface. The former type is known as air source heat pump, while the second machinery is called geothermal heat pump. Heat pumps serve for both cooling and heating the home in extreme environmental conditions.

The technology of heat pump is used in some home appliances such as heating system, freezers and air conditioners. A heat pump works by consuming a small amount of energy for transferring heat from an area with low temperature to another with a higher temperature. It is more energy efficient in comparison to heating and cooling devices like furnaces and ACs. Nevertheless like other machinery, there are certain heat pump issues, that might arise over a period. Let’s discuss in detail about troubleshooting heat pumps.

Troubleshooting Heat Pump issues

A short knowledge about the parts of a heat pump will help in a straightforward diagnosis of the heat pump Problems. The basic parts include an evaporator ( circulating fans ), reversing valve, condenser ( refrigerator coil ) and a compressor. Prior to starting with heat pump troubleshooting, turn off the power supply at the main circuit breaker. Following are just some of the common heat pump issues and methods to troubleshoot them :

No Heat Production : If there is not any heat production, then the difficulty may be due to failure in the main power supply or overloading of the motor. In order to troubleshoot this malfunction, check the power supply and thermostat and fix them ( when necessary ). In case there’s power supply, reset the motor by pressing the reset button. Also, check the ignition of the heat pump for any defects. If none of these tips work, then you can hire a professional for proper fixation.

Inadequate Heat Production : insufficient heat production is one of the major heat pump issues. In most cases, it is caused due to obstructions in the air ducts. Other reasons for this defect could be low thermostat setting and presence of dust in the air filters. You can check these systems whether or not they are working properly or not.

Low and high Head Pressure : A heat pump issue with low head pressure can be caused by a scarcity of refrigerant, damage of the compressor and soiled evaporator. On the contrary, high head pressure regularly results from overfeeding of the refrigerant and soiled condenser. Watch these systems and recheck whether the heat pumps start working normally or not.

Freezing of Heat pump : Freezing of the heat pump unit may be caused thanks to a faulty air blower or accumulation of dust and mud in the filters and evaporators. For fixing this problem, check for the defrosting option in your heat pump unit. If there is, you can defrost it and check the compressor for any defects. Do not forget to check the calibration of the thermostat.

Noisy Heat Pump : noisy functioning of the heat pumps is caused because of the reasons like loose screws, unacceptable fixation of the belts and noise from the air channels. To fix and troubleshoot this malfunction, you can tighten the screws, check the belts and introduce a plastic insulation within the metal air channels.
