Heat pump repairs: 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. Consider installing (or have a professional install) a programmable thermostat with multistage functions suitable for a heat pump. Like all heating and cooling systems, proper maintenance is key to efficient operation.
If you’re heat pump doesn’t turn on at all, you likely have a problem in one of two areas:
The unit receiving power
So what can you do? Here are some tips. You can be sure that your thermostat is set to the proper setting (meaning heat if you’re looking for heat as well as the temperature you want the room to be). If you’ve recently added a new thermostat, it may not be the right kind (your thermostat must be made specifically for heat pumps), or it could’ve been wired improperly.
You can also make sure that your heat pump is receiving power. A tripped circuit breaker could be the culprit, which is an easy fix (just flip the breaker back on). If the breaker regularly trips, then you likely have a short in the electrical system that providers power to the furnace. For that you’ll want to call a heating and cooling specialist.
