Is Your AC Blowing Warm Air?

thermometer-going-redIf so, then you have every right to be concerned. The only thing more alarming to homeowners during the height of the summer season than an AC that is blowing warm air may be an AC that has broken down entirely. While you are right to recognize that there is a problem with your air conditioner in Bolingbrook, IL, however, we want to remind you that this particular issue may not be quite as serious as it first seems. There are, in fact, several potential causes of an AC blowing warm air that you can easily rectify on your own.

That’s the good news. As always, there is another side to the coin. There is a possibility that there is no quick fix to your problem, and that you are in fact going to need professional services in order to resolve the situation. That is why it is so helpful to know what to look for in the event that your air conditioner starts to blow warm air.

The Best Case Scenarios

In the best case scenario, you are going to be able to get your air conditioner back to blowing cool, comfortable air in no time and with no help — or expense, for that matter. The first item to check is your thermostat. Yes, it sounds very obvious. No, homeowners do not always think to do so when they are worried that their air conditioner has broken down.

If your thermostat has been set to a fan-only mode, then it is still going to blow air throughout your home. However, that air is not going to be cooled down before being distributed throughout your house. It may not be quite as hot as the air outside, but it is not going to be comfortable in your living space. Simply setting the thermostat properly will reserve the problem. If you have a heat pump, you should also check to make sure that you have not accidentally switched it over to its heating mode.

If your thermostat seems to be set fine, but warm air is still blowing from the system, pop your head out the door to see if the outdoor AC unit is still running. If it’s not, then you should check your thermostat. Your indoor and outdoor units — almost certainly — run on different circuits due to the amount of power that they draw. If your breaker for the outdoor unit’s circuit has tripped, the indoor unit may continue to distribute unconditioned air throughout the house. Flipping the breaker to reset the circuit can resolve this problem.

More Serious Problems

Like we said, those are the best case scenarios. There are more serious issues that a professional will need to resolve. Notice ice on your outdoor unit? That could indicate that you have a refrigerant leak, and that the system is struggling to remove a sufficient amount of heat from the air in your home. If this is the case, continuing to run the system could do very serious damage to the compressor.

You could also have damaged ductwork trying to distribute conditioned air throughout your home. That means that they can pull hot air into the system from areas like the attic or inner wall-space. Professionally sealing the air ducts will be necessary to get the system back on track.
