Why Is Warm Air Blowing from My AC?

In many ways, modern homeowners really are spoiled. We have so many appliances and systems that make our lives more comfortable and convenient at our disposal that it can be hard to imagine living without them. Of course, no such system can ever be truly 100% reliable. That is why we sometimes are faced with stark reminders of what life would be like without them. During the hottest time of the year, you’ll learn very quickly not to take your AC for granted if it is not functioning properly.

One of the most obvious signs of trouble from any AC is a system that is not blowing cool air. Shy of a complete breakdown, this is just about the clearest signal you can get to alert you to a problem with your air conditioner. It is important to remember that, like any other air conditioning problem, there are a number of potential causes of this issue. That is why it is so important to have a trained professional diagnose the problem before completing your air conditioning repairs in Miami, FL.

What’s Going On?

We understand that warm air blowing from an air conditioner is a very alarming development. That being said, there is a silver lining to this particular cloud. In many cases, there is a simple explanation for the problem that doesn’t even require professional services. Before contacting us to repair your AC, there are a few items to check.

  • Is your thermostat set properly? It sounds obvious – and it is – but you’d be surprised how frequently homeowners are tricked into alarm by an improperly set thermostat. If your thermostat is set too high, is in a “fan-only” mode, or, if you use a heat pump, is in its heating mode still, you’ll feel warm air blowing from the vents. We love seeing our customers, but you don’t need us to come over just to adjust your thermostat.
  • Did you check your circuit breaker? Many homeowners fail to realize that their indoor AC units and the compressor/condenser outside are running on separate circuits. It is possible that the fan in your air handler is operating as normal, but that the circuit that the outdoor unit runs on has tripped. If this is the case, you can simply reset the circuit breaker to get your system back up and running properly. Double-check that the outdoor unit is working before scheduling repairs.

Other Potential Issues

Unfortunately, resolving problems with an air conditioner that is blowing warm air is not always going to be so simple. You may have a refrigerant leak, for instance, which is inhibiting the air conditioner’s heat transfer process. If this is the case, repairing the leak and recharging the refrigerant promptly is necessary to avoid potentially serious damages to your system. If you notice that your air conditioner is blowing lukewarm or even hot air, and there is no obvious cause of the problem, you are going to have to schedule professional repairs as soon as possible.
