Why Is My Air Conditioner Blowing Warm Air? Determining the Reasons and How to Fix Them.

The last thing you need on a warm day is an air conditioner that blows warm air. If your air conditioner is not cooling your home properly, you might be wondering what is wrong. There are several possible causes of warm air coming from your AC unit. Some of them are easy to fix, while others require professional help. In this article, we will explain some common reasons why air conditioners blow warm air and how to fix them. If you live in Central New Jersey or nearby areas, you can contact Bill Leary Air Conditioning & Heating for reliable and affordable AC maintenance and AC repair services. We serve both residential and commercial customers with quality HVAC solutions.

Air Conditioner Troubleshooting

To solve some AC issues quickly, check these factors:

  • Are the windows open while the AC is on?
  • Are some rooms isolated from the rest of the air flow?
  • These can cause uneven cooling in your home or office.


For central AC, also verify these settings:

  • Is the thermostat at the right temperature?
  • Do the batteries in the thermostat need changing?
  • Are the fuses or breakers working properly? Wait for at least five minutes before resetting the breakers if needed.

Situations That Require Professional Air Conditioning Services

If there is not a simple solution to the problem of your air conditioner blowing warm air, you probably need to arrange for professional services with an HVAC company. Exercise caution when inspecting and handling components of the air conditioning system.

Here are a few trouble areas that may arise:

  • Insufficient refrigerant levels, resulting from leaks or poor maintenance
  • Dirty or clogged air filters, restrict air flow and reduce the effectiveness of air conditioning
  • Blocked air vents, including dust, debris, leaves, and other materials
  • Frozen mechanical components may require air conditioner repair services or replacement
  • Faulty components, including condenser fan, compressor, expansion valve, and evaporator cell
