Why Is My AC Not Blowing Cold Air?

June 2, 2022

By Thomas Grant

It’s a scorching summer day in Georgia, and your home has rapidly increased in temperature.  Unfortunately, when you turn on the air conditioner, the air conditioner is running, but your house is not cooling!

There are many reasons why your air conditioning may not be blowing cold air. Knowing what some of these are can help you create a plan to fix the problem and ensure you’re able to cool down your home — particularly when temperatures are rising outside. 

If you’ve ever asked yourself: “why is my air conditioner running but not cooling the house?” We’ve got you covered! 

Here are some reasons why this could be happening to you. 

Your A/C Unit Could Have Lost Power 

A/C units pull a lot of energy, and for this reason, there could be an internal or external power problem. For example, the A/C unit could have blown a fuse or damaged the motor itself. We recommend checking your breaker box and the inside of the air conditioner unit to see if it has lost power. If this is indeed the case, it is a quick fix. Simply replacing the cooling element of your unit is all it will take to get your air conditioner back to work. 

Your Air Filter Is Dirty 

It’s easy to forget that your A/C unit has air filters that function to filter out dust and grime. Air filters are an essential part of your unit and, if not regularly cleaned, can contribute to the air conditioner not cooling your home. An unclean air filter can cause motor failure because it cannot pull the air it needs to cool your home. Therefore, it is vital to check the air filter to see if it’s brown or gray; and if so, it is time to replace it. 

Make Sure the Thermostat is Set to the Correct Setting 

Ensuring that your thermostat is in the right setting helps your air conditioner blow cold air. Sometimes, although one person has the thermostat set on the cool setting, it may get unintentionally changed to the fan setting instead. If that’s the case, your A/C is likely blowing warmer air. Again, this is a quick fix and won’t require any repairs. 

Your Compressor or Condensor is Blocked 

Your air filter is not the only part of your A/C unit with a blockage. Air compressors compress the refrigerant compound, while a condenser allows for the collection or release of heat (depending on the time of year). Debris like leaves or dirt could block these pivotal components of your A/C unit and contribute to it not cooling your home. Fixing these units could be as easy as clearing out debris. However, if removing debris does not solve the problem, a more complex issue is at hand. In that case, we recommend that you call an HVAC professional. 

Losing the functionality of your A/C unit is stressful — especially when you need it the most. If your air conditioner is not cooling your home, give our dedicated team a call today at (404) 296-6190 to allow us to assess the issue quickly.
