Heat pumps are amazing devices that can be used to heat and cool your building from a single unit. However, as in the case of most of other mechanical devices, heat pumps are also vulnerable to a number of issues. Discussed further in this article is a brief guide to troubleshoot different types of heat pump problems.
Heat Pump Does Not Heat: This primarily occurs as a result of motor overloading or failure in power supply. One of the best ways to troubleshoot this issue is to check the thermostat and power supply. If there is power supply, press the reset button to reset the motor.
Noisy Heat Pump: Most of the latest model heat pumps operate quietly. Hence, if any noise comes from heat pump, it may be due to problems like loose screws, nuts, or bolts. Inappropriate fixation of belts can lead to noisy heat pump. You can overcome this issue by properly securing the screws and checking the belts.
Frozen Heat Pump: This problem can occur due to a variety of reasons. For instance, air filters filled with dirt and debris can result in the frosting of heat pump. Air blower issues and defective compressor are the other reasons for heat pump freezing.
Low and High Pressure: Among the major causes for heat pump problems with low head pressure are defective compressor and evaporator issues. When it comes to high head pressure, it is usually due to contaminated condenser and overfeeding of refrigerant in the unit.
