If your air conditioner is blowing out warm air, it may not yet be time to call your local cooling and heating repair charlottesville. The fact is there are a number of possible reasons that could lead to your AC unit malfunctioning in this manner. Some are simple to fix, others may indeed require you to call in the experts for a professional solution to the problem.
But you can’t get to fixing the issue if you don’t yet know what it is. Fortunately there are some basic air conditioning problems that are easy to diagnose yourself, without the need for paying big bucks just to deal with the matter.
So let’s review the most common diagnoses as to why your air conditioner is blowing out warm air instead of the cool, clean, refreshing alternative:
Yup, it may be as easy as checking the settings on your thermostat. Most of them have a switch that allows you to set your HVAC system to “cool’ and “heat”. Be sure your thermostat is set to the former and not the latter position.
While you’re at it, take a look at the switch that reads “auto” and “on”. If you have it on the latter, your system’s fan is going to blow air out of the vents even if the air conditioner isn’t running. As a result, that air will be warm instead of cool.
So take the time to give your thermostat a good examination before you decide it’s time to call your preferred repair shop to take a look at your air conditioning unit.
If your system’s airflow is the culprit, then you need to take steps to determine whether your theory is indeed correct. The first place to look is the air filter. You should change it every two-three months and failing to do so can have a detrimental effect on the proper operation of your system.
If the air filter isn’t the issue, then it’s possible your coils haven’t been serviced in some time and that they need to be cleaned.
In either case, a lack of airflow can have other consequences. The warm air is only one part of it. Your compressor could freeze up or your entire system could work a lot harder to attempt to blow cool air and that overtaxed system could just seize up at some point and stop working altogether.
Your return duct could be leaking because it’s come loose or become broken. When this occurs, your system could be sucking in warm air from outdoors or some other warm space in the home, like an attic.
If the return duct is the culprit then you will need to have your return duct diagnosed by a professional heating and cooling repair company.
All air conditioning systems need freon or refrigerant to work correctly. If your system is low on refrigerant, then the air conditioning unit will blow warm air no matter how your thermostat is set.
