Why Is It So Hot Upstairs in My House? Top HVAC Solutions
There are several reasons why your AC could be running but not cooling. As frustrating and confusing as it is, there are normally a few common issues that could be happening.
The good news? You can check a few simple things before calling a pro.
Common Issues — Why Your AC Isn’t Cooling Your Home
Let’s rule out a few common AC components that could be causing your unit not to cool.
Incorrect thermostat settings. Check your thermostat settings. Make sure you have it set to “cool” and not “fan.”
Clogged air filters. Check to see if your air filter looks clogged. A clogged air filter will definitely make cool air feel warmer.
Dirty outdoor unit. See if your outdoor unit is unusually dusty or dirty.
Blocked ducts. Investigate your vents or ducts. Ensure no furniture or rugs are blocking your vents or ducts.
Wrong sized unit. If you have a smaller unit than what your home actually needs, then your home may never feel consistently comfortable.
Leaking refrigerant. Check on your AC’s refrigerant. This is what makes the air cool. Also check for hissing, bubbling, or ice along the refrigerant lines.
Damaged heat pump. If your home has a heat pump, there may be damage to its coils or refrigerant lines.
At Home Solutions
There are a few things you can do at home to not have to call in any experts. Thermostat setting issues are super common and easy to fix. If your screen is blank, try to put new batteries in the thermostat. Make sure you have the settings calibrated correctly and set to “cool.”
Homeowners often overlook air filters. Try replacing the air filter. Change them every 1-3 months depending on the size of your home. Cleaning your outdoor unit may solve your cooling issue as well.
Make sure hot outdoor air isn’t overpowering the system — close and properly seal windows.
