“My AC is blowing hot air. Why is that?” — At Unique Indoor Comfort Heating and Cooling, we get questions like this all the time. So if that’s on your mind, keep reading. You’re in the right place, and the experts for air conditioning repair in Palatine have you covered.
Your air conditioner is one of the most important elements of your home, especially in the warm summer heat. So if you notice that the air coming out of it is lukewarm or even warmer than that, that could be a huge issue.
After all, it should blow out cold, fresh air at a moment’s notice. So the first step is to contact Unique Indoor Comfort Heating and Cooling if you notice the AC blowing hot air.
Beyond that, let’s talk about the reasons behind your air conditioner blowing hot air:
Reasons For Your Air Conditioner Blowing Warm Air
Let’s look at some of the common causes of the AC blowing lukewarm air:
The Thermostat Is Off
If your AC unit keeps blowing lukewarm air, your thermostat might not be adjusted to the right temperature. It may seem like common sense, but you should probably check the thermostat level really quickly.
You could have accidentally bumped it or adjusted it to a higher temperature. If that happens, then the fan can keep running and circulate warm air in the home.
After all, if the thermostat is on, it will continue to circulate air throughout the system — even if cooling is not working. So give your thermostat a quick check.
The Unit Might Not Have Power
Your AC needs a lot of power and electricity in order to run properly. Make sure that a circuit breaker didn’t go off or that it didn’t lose power somehow. An AC blowing warm air means that its cooling function could be without the necessary electricity.
Additionally, you could have had an HVAC tech out to your home recently. And if they turned off the outdoor unit, they could have forgotten to turn it back on. Make sure your unit is receiving power by checking the box on the exterior wall beside your unit.
Your Unit Might Be Crowded
The condenser of an air conditioner unit is responsible for releasing heat and so it needs room to ventilate properly from the top and sides.
Some homeowners make the mistake of hiring unprofessional HVAC technicians that install their AC units somewhere without proper ventilation such as a crawl space or deck underneath the deck.
However, in reality, your condenser needs at least one foot around it and five feet above it to operate properly. If not, you could be experiencing warm air.
The Air Filter Needs To Be Changed Out
Your air filter is responsible for filtering out debris and small items like dust that can get into your system. Otherwise, if your filter is clogged, your AC unit has to work harder to circulate the cool air.
This results in the indoor coil, which is also called an evaporator coil, not giving enough air blown over it. Since this contains the refrigerant within, it needs that air to cool the rest of the home.
The end result is that the evaporator coil can freeze while the AC itself overheats. From there, your compressor could actually die, if not at least overheat.
If you have ice on your evaporator coil, you need a new filter ASAP. That way the ice can melt, but you should turn the cool setting off in the meantime.
Then once the ice has melted away, you can start using the AC like normal again. If you have any doubts about this, have HVAC professionals come out and check the system for you.
