How should I maintain my heat pump?
Here are a few tips for the proper operation of a heat pump and optimizing your energy saving:
- Do not setup backup heating systems on your thermostat; backup heating systems are usually more expensive to operate.
- Continuous indoor fan operation also can degrade heat pump performance unless a high-efficiency, variable-speed fan motor is used; operate the system on the “auto” fan setting on the thermostat.
- Proper maintenance is the key to efficient operation; the difference between the energy consumption of a well-maintained heat pump and a severely neglected one ranges from 10%-25%.
- Clean or change filters once a month or as needed, and maintain the system according to manufacturer instructions; dirty filters, coils, and fans reduce airflow through the system; reduced airflow decreases system performance and can damage your system’s compressor.
- Clean outdoor coils whenever they appear dirty; occasionally, turn off power to the fan and clean it; remove vegetation and clutter from around the outdoor unit.
- Clean the supply and return registers within your home, and straighten their fins if bent.
Have a professional technician service your heat pump at least every year, the technician can do the following:
- Inspect ducts, filters, blower, and indoor coil for dirt and other obstructions
- Diagnose and seal duct leakage • Verify adequate airflow by measurement
- Verify correct refrigerant charge by measurement
- Check for refrigerant leaks • Inspect electric terminals, and if necessary, clean and tighten connections • Lubricate motors, and inspect belts for tightness and wear
- Verify correct electric control, making sure that heating is locked out when the thermostat calls for cooling and vice versa
- Verify correct thermostat operation
