Why Would My AC Blow Warm Air?

thermometer-in-the-redSummers here in Vermont are not as intensely hot as in certain Southern and Southwestern areas of our country, but things still get plenty uncomfortable when the temperature starts to rise once more. If you are serious about keeping your home cool and comfortable regardless of how hot it may get outside, you need to have a great AC installed in your home. Of course, even the best air conditioners may run into operating trouble from time to time. If your air conditioner in Springfield, VT is blowing warm air, it should be pretty obvious that something is wrong.

The good news is that the problem causing your air conditioner to blow warm air may not be all that serious. In fact, it could be a very simple case of user error. There are also some potential issues that could be quite serious, though. Following are a few items to check should you find your AC blowing warm air, as well as a couple of examples of more serious problems that could be in play. Contact us if there is no clear solution in your situation.

Simple Solutions

Since you will want to check these items before scheduling professional air conditioning repair services, let’s first start off with some potential problems that have very simple solutions. These are your best case scenarios in the event that your air conditioning starts to blow warm air. These are not the types of issues that you will require any professional help to resolve.

  • Improper thermostat settings. Yes, this sounds very obvious, but always be sure to check your thermostat if your air conditioner is blowing warm air throughout your house. Obvious as it may seem, those homeowners prone to alarm may forget to check their thermostats before dialing the phone. If your system is set to a fan-only mode, unconditioned air may be pumping through your ducts. Use a heat pump? You may have it set to heating mode accidentally. A quick adjustment at the thermostat can resolve either issue.
  • Tripped circuit breaker. Another very benign problem is that of a tripped circuit breaker. This is not as immediately obvious as the thermostat issues above, but still very easy to correct. Check your outdoor unit to see if it is running. If not, your indoor unit — which is almost certainly on a different circuit — may be up and running, but acting simply as a fan. By resetting the appropriate breaker with the flip of a switch, you can get your system back up and running properly.

Serious Situations

Unfortunately, there is no guarantee that your problem is going to be so easy to fix. There are various ailments that could cause your system to blow warm air into your home and which will require professional service.

  • Refrigerant leaks. This is one of the most serious issues that can affect any air conditioning system. If your system does not have enough refrigerant in it, then it will struggle to remove a sufficient amount of heat from your home. It will strain the system, and could result in serious damages if left unresolved.
  • Duct leaks. Perhaps not quite as serious as a refrigerant leak, but very problematic nonetheless, is the duct leak. If your air ducts are leaking, they could pull unconditioned air into the system from spaces like the attic or inner wall-space. Leaky ducts must always be professionally sealed.
