But in the meantime, don’t hesitate to attempt an at-home diagnosis. Here’s a list of potential reasons why your home air conditioner isn’t working properly:

Your thermostat isn’t on the right fan setting

This is the simplest fix, and we know what you’re thinking- but seriously! It happens to the best of us.

Double-check that your thermostat is set to “cool” to keep your fan running cool air, or set to “auto” so that your fan automatically runs when your house needs cool air.

If your thermostat is set to “heat,” you have your answer! Even if it is set to “on,” this means that your fan will keep blowing air even when it’s not cooling.

Dirty air filters

Air filters should be changed every 60 – 90 days. When your filter has been collecting dirt, dust, allergens, etc. for 90+ days, it clogs up, restricting airflow and becoming useless & hazardous to you and your family’s health. It can even prevent your AC system from cooling properly.

Make sure to check your air filter every two to three months, more often if you have pets or serious allergies.

Refrigerant leak

Refrigerant is a liquid responsible for absorbing heat from the air in your system. Low or leaking refrigerant means that your air system will blow much warmer than normal. If your AC unit is low on or leaking refrigerant, call an HVAC technician ASAP. The longer you wait, the worse it will get- and refrigerant leaks can be a serious health & environmental hazard.

Circuit breaker needs to be reset

Both your outside & inside units have their own breakers. If your outside breaker flips for any reason, the inside unit will blow air at the outside temperature- meaning that in the summer, it’s HOT.

Check the breaker box and if this seems to be the problem, simply reset the circuit breaker. If this happens again, do not reset the breaker once more & risk damaging your system. Just call an HVAC technician!

Disconnected or damaged return duct

If your return duct is either disconnected or damaged, it will suck in unconditioned air from outside, from your garage, or from your attic space, and blow into your home. That means stale, musty, hot air is circulating throughout your house.

This problem will also require the help of a professional. Call (502) 443-9391.

These are just a few of the many reasons your AC unit is blowing hot air throughout your home.
