Proper operation of your heat pump will save energy. Do not set back the heat pump's thermostat if it causes the backup heating to come on -- backup heating systems are usually more expensive to operate. Continuous indoor fan operation can degrade heat pump performance unless your system uses a high-efficiency, variable-speed fan motor. Operate the system on the "auto" fan setting on the thermostat.
Like all heating and cooling systems, proper maintenance is key to efficient operation. The difference between the energy consumption of a well-maintained heat pump and a severely neglected one ranges from 10% to 25%.
Clean or change filters once a month or as needed, and maintain the system according to manufacturer's 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 in your home, and straighten their fins if bent.
You should also 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 obstructionsDiagnose and seal duct leakageVerify adequate airflow by measurementVerify correct refrigerant charge by measurementCheck for refrigerant leaksInspect electric terminals, and, if necessary, clean and tighten connections, and apply nonconductive coatingLubricate motors, and inspect belts for tightness and wearVerify correct electric control, making sure that heating is locked out when the thermostat calls for cooling and vice versaVerify correct thermostat operation.
