More than 87% of American homes have some form of air conditioning. Many homes have central air, while others use alternatives like window units and portable air conditioners instead. 

We rely on air conditioning to keep our homes cool and comfortable. That’s why it’s so frustrating when you have air conditioning problems.  

Luckily, we’ve outlined the most common air conditioning issues and what they mean below. Plus, you’ll learn some AC troubleshooting tips and when it’s time to call a pro to handle your AC repair.

1. My AC Unit Is Blowing Hot Air

One of the most common air conditioning issues is when the unit blows hot air instead of cold. First, make sure your unit is set to AC and not heat, as this can happen.

If that’s not the issue, you could have low refrigerant or a dirty evaporator coil caused by a dirty air filter. Your outside unit could also have lost power due to a tripped circuit or blown fuse. If you still can’t figure it out, call for repairs

2. The AC Isn’t Keeping Up with the Thermostat

If your AC isn’t cooling your house to the temperature setting on your thermostat, debris like grass or plants might be blocking your outdoor unit. It could also be a leak in your air ducts. 

It could even be an issue with your attic ventilation or a lack of insulation in your home. If you’re not sure what the problem might be, find a local AC maintenance technician to investigate. 

3. The AC Unit Won’t Turn On

If your AC won’t turn on, first check the batteries in your thermostat. If that’s not the problem, make sure the thermostat is on and set to AC mode. 

It could also be from a tripped circuit breaker or blown fuse. Try resetting your circuit breaker or replacing the fuse.  

4. My AC Unit Runs Constantly

If you’ve just had a new AC unit installed but it runs constantly, it could mean the unit isn’t large enough. 

If this is a new problem, it could point to an issue with the blower or fan. You might also have a clogged air filter, dirty condenser, or a thermostat issue. This can be a complicated problem to diagnose, so you may want to call in a technician. 

5. The AC Makes Strange Noises

AC noises can point to a range of different problems, so decide what the noise sounds like. If it’s hissing or buzzing, that could mean a refrigerant leak or an electrical problem. 

If you’re hearing banging or thumping, that’s a sign of a blower or motor problem. If you hear screeching, you might have a problem with your fan motor or compressor. It’s best to call a service technician before the problem gets worse.
