HEAT PUMP SERVICING
Proper operation of your heat pump will save energy.
You should also have a professional technician service your heat pump at least every year. The technician can do the following:
Check for refrigerant leaks
Inspect electric terminals, and, if necessary, clean and tighten connections, and apply nonconductive coating
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
Check power voltage is correct
