AC Repair: Why Is My Heat Pump Not Cooling?
Here is a simple checklist for you troubleshooters out there. DISCLAIMER: heat pumps are complex systems that utilize large amounts of electricity. Do not take any action that might bring you in contact with high voltage.
Your heat pump is blowing warm air? Or it is blowing no air? Or it’s not turning on at all? We’ll address the things that can cause problems for you, so you can hopefully prevent an AC repair bill and get right back to the business of being comfortable.
The very first thing you can do is make sure that your thermostat is set correctly. It should be set to AUTO or COOL, or to HEAT depending on the season, and the setting temperature should be, at minimum, a couple of degrees below (or above for heating) the actual temperature of the home.
Tripped Breaker and Other Miscellaneous Power Issues
One of the first things you can check yourself is whether or not your heat pump is receiving power. Most residential installations have the outdoor unit easily accessible outside the building. Turn your thermostat down a few degrees and go outside to check the unit. Be sure to give the system up to 8 minutes to cycle on after you lower the thermostat.
If it is not turning on at all, it’s possible you’ve got a power interruption somewhere. You can go check the breakers to see if they are tripped. If, however, resetting breakers doesn’t work, or they trip again, stop troubleshooting and call an AC repair professional. Power issues are not to be taken lightly.
This could also be a bad capacitor, which, fortunately for you, is one of the least expensive AC and heat pump repairs we’ll discuss today.
If your blower is turning on and blowing air, but the air doesn’t feel cold, you may have low refrigerant. You can’t check this yourself, but AC repair contractors can diagnose and fix this quickly, and it’s not the most expensive repair on this list.
In older systems that use R22 refrigerant, this could cost a little more, as that refrigerant is being phased out and current supplies are getting more expensive.
Airflow issues can also cause insufficient cooling. If your vents are blowing weakly, or not at all, check your air filters and clean them according to the instructions provided with your heat pump. Dirty filters can cause an excessive buildup of cold air inside the units themselves, making them ice over.
This insulates the coils and prevents them from cooling the air properly. You’ll have to defrost those by blowing the fan for a while before your system will work properly again. If not, call your AC repair contractor.
