Troubleshooting: Common Heat Pump Problems
A heat pump is a multi-function unit that acts as a central air conditioner that can also provide heat by reversing itself and drawing in heat from outside air. Since it’s very similar to an air conditioner, the maintenance needs to fix your heat pump are like those of a regular A/C unit. Here are some common heat pump problems. Plus the reasons those problems are occurring and some easy ways to fix your heat pump problems.
Troubleshooting: Common Heat Pump Problems
THE PROBLEM: The heat pump won’t turn on
Reason: There’s a problem with your thermostat
Solution: If you’re trying to heat your home, make sure your thermostat is set to “heat” and a higher temperature than room temp. For cooling needs, you’ll need to do the opposite. Check to make sure that the thermostat isn’t just set to “fan only”. If you’re unfamiliar with your unit, contact an HVAC professional to help walk you through the steps to set the temperature of your heat pump correctly.
Reason: Tripped breaker
Solution: Check to see if the breaker to your heat pump is on. Then check the main electrical panel in your home. The breaker may simply need to be reset by flipping over a switch.
Reason: Wiring problems
Solution: Turn the heat pump off and inspect the wiring of the unit. If you notice any spots where the wire is damaged or frayed, contact a professional immediately to fix.
THE PROBLEM: The heat pump is on but not providing heat
Reason: Dirty indoor coil
Solution: Clean the coil. If the problem persists or you can’t remove buildup, have a professional clean and inspect the entire unit.
Reason: Dirty filter
Solution: Clean or replace the filter. Make sure you’re cleaning your filter every 30 days
Reason: Indoor fan problems
Solution: Your blower drive belt may be loose or slipping. Contact a professional to properly tighten the belt and clean the fan
Reason: Leaking Valves
Solution: Contact a professional to repair or replace
Reason: Low refrigerant
Solution: If the heat pump is low on refrigerant, there could be a leak in the unit. Refer to an HVAC professional to inspect and repair the leak and then recharge the refrigerant.
THE PROBLEM: You have frost buildup on the indoor (evaporator) coil

Reason: Indoor fan problems
Solution: Your blower drive belt may be loose or slipping. Contact a professional to properly tighten the belt and clean the fan

Solution: Call an HVAC professional to inspect and thoroughly clean the coil/unit
Problem: The heat pump is leaking liquid
