Why is My Air Conditioner Blowing Warm Air?
While there are many reasons your air conditioner is blowing hot air, here are the most common causes:
- The thermostat is set incorrectly - double-check your thermostat and make sure it isn’t set to “heat”. It may sound silly, but we’ve seen it happen before. Also, check to see if you have your thermostat set to “auto” or “on”. If it’s set to “on”, that means the fan will blow even when the air conditioner isn’t actually cooling.
- There’s a restriction in airflow commonly a result of one or more of the following: the air filter hasn’t been replaced in a long time; you haven’t had maintenance done on your AC this year (so the coils are dirty); and, the outside unit isn’t getting electricity. Restricted airflow can also cause the compressor (the part that moves the refrigerant) in your air conditioners outside unit to freeze up.
- Check to see if your circuit breaker has tripped or fuse has blown on the electrical panel to make sure the circuit is supplying electricity to the outside air conditioning unit. This is a sign that there could be a major problem and you need to call a professional immediately.
- Other causes include a problem with the compressor/outside unit or your air conditioner is low on refrigerant. You may also have a return duct that is broken or disconnected and is pulling in unconditioned air from outside or an attic space. Both of these issues require a professional’s help.
It’s important to note that if your air conditioner is getting up there in age and/or experienced more than one or two problems last season, it may be time for replacement. Choosing the right furnace or air conditioning unit is crucial to maintaining energy efficiency in your home and keeping your energy bills low.
