Even though Ohio is in the Midwest, we do experience hot days in the summer. When your heat pump stops cooling, that’s why it’s a good thing there are steps you can take to try to get it running again before you resort to calling an expert.
Heat Pumps Stop Cooling: What to Do
- Clean the filter. Like A/Cs and furnaces, heat pumps have filters that you should clean and/or replace regularly, according to the manufacturer’s instructions. Inspect the filter monthly and replace or clean it when it looks dirty. Your heat pump user’s manual can tell you which is recommended.
- Look at the settings. Check your thermostat to see if you set it to cool instead of heat. When it’s in the cooling-related setting, set it to “automatic.” If this doesn’t work, try operating the heat pump on the “fan only” setting to ensure the fan works. Then look at the temperature settings. If the temperature is set too low, the heat pump’s cooling function won’t start.
- Investigate the power source. Perhaps there was a power outage, a blown fuse or the circuit breaker tripped. Try resetting the breaker for the heat pump. Also, check the switch on the wall or panel near the heat pump. If you can’t get it to kick on, call your HVAC specialist for assistance.
- Defrost it. A heat pump stops cooling if it doesn’t defrost long or often enough. When this is the case, run it on the “fan only” setting for 60 minutes. If the problem persists, call your HVAC technician.
- Replace the batteries. If your thermostat runs on batteries, they may be dead. Replace the batteries to see if the heat pump starts.
- Check the outside unit. Your condenser/compressor unit may not be getting sufficient airflow. Make sure no weeds, grass, dead leaves or other yard debris is blocking the flow of air.
