One of the most frustrating things that can go wrong with your air conditioner is that it stops blowing an adequate amount of air (or any air at all). If this ever happens in your home, it’s helpful to know some of the possible explanations so that you can properly troubleshoot the problem. Today we’re going to talk about 5 possible reasons why your air conditioner is not blowing air and what you can do to address the issue!

5 possible reasons why your air conditioner is not blowing air

  1. Air filter is severely clogged. Your air filter collects dust and other airborne particles to protect your cooling system and provide your home with healthier air. When your filter becomes clogged with those particles, your air handler has a very hard time pushing air past the filter. In cases where filters are severely clogged, it will become nearly impossible for your air handler to supply your home with an adequate amount of air. This issue can be fixed by simply installing a fresh filter in your air conditioner.
  2. Thermostat settings are wrong. Depending on how your thermostat is set, your air conditioner might not be blowing any air simply because it is not being told to turn on. First, check to ensure that your thermostat is in the “cool” mode instead of the “heat” mode. Next, ensure that the temperature at which you’ve set your thermostat is lower than the current temperature in your home. You might simply have a high thermostat setting, which will prevent your air conditioner from turning on until your home’s temperature rises to that level.
  3. The air conditioner is not receiving power. If your air conditioner is not receiving any power, your air handler will not be able to run. This might be the case if your air conditioner is not making any noises at all and your thermostat is set properly. You can try and fix this problem by checking to see if your circuit breaker tripped.
  4. Air registers are blocked or closed. Do you hear the sound of your air conditioner turning on, but no air is coming out of the supply registers? Or are some rooms in your home getting air while others aren’t? Check to ensure that all of the air registers in your home are open and that none of them are blocked by furniture, rugs, or other obstructions.
  5. Air handler issues. As with any major appliance, your air conditioner can sometimes run into mechanical problems. If there are issues with any of your air handler’s parts, it won’t operate properly and you should have it inspected by a professional like Jerry Kelly Heating & Air Conditioning.
