There’s a situation that no one is ready for, and it’s the moment when your air conditioner is turned on for the first time in months after the cold winter season, but only blows out warm air. For people anyone familiar with the scorching hot summers in North Texas, this is a signal that immediate action is needed. At Ellis Air Conditioning and Heating in Dallas, TX, our team of experienced HVAC technicians has been working with residents and businesses throughout the DFW Metroplex for decades on a wide variety of heating and cooling concerns including air conditioner maintenance and repairs.

If your air conditioner isn’t generating the cool air you need to make your indoor areas comfortable as the temperatures rise, the first and most important thing to do is to stay calm. While it can be surprisingly easy to get upset and frustrated when dealing with this type of situation, it can make the entire process of getting it resolved much more complicated than it needs to be. To give our customers, and our readers, a better idea of some of the most common reasons why their A/C unit might be blowing out hot air, we decided to spend a little time going over the topic.

Start by Checking Your Thermostat

This might sound like an obvious step to take, but the first thing to check is your thermostat. If your air conditioner is generating hot air, the thermostat might not be set correctly. If this is the case, then the fix is thankfully very quick, and very simple. Just turn the thermostat setting back to ‘cool’ and check if the air conditioning system starts sending cold air your way.

Depending on the type of thermostat you have, you will also want to make sure that the battery is working and that the temperature is not set too high. Remember that the ‘auto’ setting will only activate fans when the air needs to be heated or cooled. The ‘on’ setting means that the fan stays on all the time to circulate air even when the A/C unit is not actively cooling the air. We recommend that you use the ‘auto’ setting most of the time and only change it to on if necessary.

Check the Circuit Breaker

After checking the settings and battery power on your thermostat, another component that may be the source of your trouble is the circuit breaker. HVAC systems require a lot of electricity to operate. In some cases, an unexpected event could cause your circuit breaker to trip, and it will turn off the power automatically as a precaution.

To make sure this is not the case, find your control panel and look for tripped breakers that could indicate a problem. If you do find a breaker that has been tripped automatically, make sure to move it completely into the off position first, and then flip it back to the on position. If you have a blown fuse, it will need to be replaced. Also, this can be a great opportunity to label all your circuits if they are not already to avoid continued confusion down the road. 

Don’t Forget About Your Air Filters

While the air filters of your HVAC system would not be directly responsible for warm air coming from your air conditioner, dirty filters can create problems for other parts of the system including the evaporator coils. This means dust and debris can accumulate on the filters, preventing smooth airflow, and this, in turn, can harm the functionality of your evaporator coils which may prevent your air conditioner from cooling air normally.
