Why is my air conditioner blowing warm air?

There are a lot of reasons why your air conditioner could be blowing warm air, and fortunately, some of them can be taken care of at home. However, for those that can’t, you have Dowd’s Mechanical, Heating & Air Conditioning available to handle all your air conditioner repairs in the Philadelphia, PA area!

There are three main reasons why your air conditioner could be blowing warm air:

  1. Issues with the thermostat settings – the thermostat is the first thing you should check when you’re having air conditioner problems because the issue could stem from incorrect thermostat settings or loose or damaged thermostat components. If adjusting the temperature doesn’t seem to fix your problem, remove the cover of your thermostat and check for loose wires. If something doesn’t look right, call us for speedy repair!
  2. Ice accumulation on the evaporator – this is another very common reason why air conditioning systems blow warm air. Ice on the evaporator coil prevents the refrigerant from extracting heat from the ducted airflow, which means the warm return air isn’t cooled before it recirculates into the living spaces. The accumulation could be due to a variety of factors, so it’s best to contact a professional to determine the root of the problem so it can be fixed.
  3. Airflow restrictions somewhere in the forced-air system – this is usually the simplest problem to fix for your AC. Just walk around your home and inspect the registers and vents and remove any items that are blocking the flow of air. Head outside and check your outdoor unit—if there isn’t approximately 2 feet of clear space around your system, start clearing things away or trimming the bushes.
