Proper operation of your heat pump will save energy. Don’t 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 a high-efficiency, variable-speed fan motor is used. 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 10-25%.
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 with the home, and straighten their fins if bent.
You should have a professional technician service your heat pump at least every year to help prevent deterioration of the system and its components.
