Why is My Air Conditioner Not Cooling the House?

Staying cool and dry is an essential part of being comfortable, and there’s nowhere you want to be more comfortable than in your own home. So when the air conditioner isn’t working correctly, it can be very frustrating. Your HVAC is something you probably don’t think about unless you don’t have it. So if you’re asking, “Why is my air conditioner not cooling the house,” here are some troubleshooting tips you can use to find the answer.

Check if the Air Conditioner is Running

The first step is to determine if the air conditioner is running or not. If the air conditioner is running but not lowering the temperature, there are a few things to check before you External link opens in new tab or windowcall a professional for help. First, look at your thermostat. If it’s switched to “on,” the AC will constantly run whether it needs to cool or not. You’ll want to change it to “auto.” Next, look at the air filter. If it’s filthy, a new filter may fix the problem. With a clean air filter, the air conditioning unit will be able to cool your home efficiently. Another common problem is that the circuit breaker for the air conditioner is tripped. Go to your breaker box and check it. Fixing the problem may be as simple as flipping the switch to reset the circuit. Finally, look at the air conditioning unit outside. It might need to be cleaned or have obstructions removed. If none of these steps have worked, you’ll need to call a professional to fix the air conditioning.

The Air Conditioner Isn't Turning On

If the AC doesn’t run at all, there could be a problem with the motor. Check the unit outside to ensure it’s plugged in. Inspect the cables for damage or interruptions. If all of your cables are in good shape and everything is connected, the coil may be frozen, or something might be broken within the air conditioning unit. You’ll want to call a professional for an expert repair.

The Air Conditioner Isn't Powerful Enough

Another possibility is that the air conditioner is doing everything it’s supposed to, but your expectations are a bit high and you think the AC is not cooling. Your AC is designed to maintain your home 20-25 degrees cooler than the outside air. If it’s 100 outside, an AC isn’t going to be able to keep your home cooler than 75 or 80. If you’re expecting more than that, you’ll be disappointed. If your home isn’t within the normal cooling range, it’s possible that you need a new unit or that your current AC isn’t powerful enough for your home. If you’ve put a significant addition onto your home, for example, you might need a bigger air conditioner.
