Reasons Why My AC Might Be Blowing Warm Air

There are various reasons that your AC might be blowing warm air. However, if you have never run into this issue, you might be feeling lost and worried that your AC isn’t going to work again without major repairs. You might be able to diagnose what is wrong with your AC unit before you ever have to call someone to come and take a look. Some fixes can be quite simple, such as a thermostat that is not set properly, while others will require the help of a skilled repair person.

A quality AC company in Lawton, OK, can easily come to your home and take a look at your AC that is blowing warm air. If you have the time to look at these common issues and see if you can resolve the issue yourself first, you might be able to save yourself some money and time. Let’s talk about some common reasons that your AC unit could be blowing warm air so that you are able to provide the AC company with more information if you do end up needing a repair expert to take a look.

Reasons That Your AC Could Be Blowing Warm Air

1.     Thermostat Settings

Sometimes, the only thing that is wrong with your AC unit is that the thermostat got changed to heat instead of cool. Maybe the temperature settings were changed, and the max temperature before the AC comes on has been increased. Another common problem is that the thermostat needs a new set of batteries.

Thermostats can also go bad, and a blank screen or a screen that no longer responds to inputs can indicate that your thermostat has decided to kick the bucket. You might be able to tackle replacing this simple part yourself, but you can always call a repair person to come and take a look if you think that your thermostat has reached the end of the road.

2.     Dirty Air Filter

Your HVAC system needs to have a fresh air filter installed on a routine basis so that airflow can be maintained and so that dust, grime, and grit can be collected and trapped inside the filter. Clogged filters will be dark, dusty, or grimy, indicating that it’s time to replace them with a fresh filter. You might be shocked to find that a simple filter change was the only reason that your AC wasn’t doing a good job.

If you are not comfortable changing the air filter in your HVAC system, just call an experienced HVAC team, and they will happily come handle this task for you.

3.     Tripped Breaker

Sometimes power surges or other power blips can cause a breaker to trip in your breaker box. The AC might be unable to start up due to a lack of power if this has taken place. Simply go to your breaker box and take a look at the switches. Many HVAC companies will label the breaker associated with the HVAC unit quite clearly.

If the breaker is tripped, simply switch it back. If the breaker flips again, there might be an issue that is causing too much power to flow through the system. You may need to have someone come and take a look at your breaker box or have an HVAC repair person come check out the power to your AC unit if the breaker keeps being flipped.

4.     Blocked Outdoor Unit

If you have an outdoor AC unit, you cannot allow it to become blocked by grass, trees, objects, or shrubs. Blocked units can overheat, leading to failure. Even if the unit has not failed, being blocked can lead to it having issues cooling down your home properly. Make sure that you keep the area around your AC unit clean and clear so that it will not be impacted by overheating or a lack of airflow.

Things That an AC Repair Person Can Come to Your Home to Fix

Sometimes, your AC is not working because something more complex is going on. Your AC unit might have frozen evaporator coils, which causes the coils in the unit to turn to a block of ice. You could also need someone to come and resolve a refrigerant leak that is leading to your AC unit being unable to blow cold air.

Issues with ducts or vents in your home can also cause problems with the AC unit operating efficiently or being able to cool your home correctly. Your unit’s compressor can also fail or there might be problems with the electrical connections that can lead to your AC unit being unable to blow cold air.

Be sure that you don’t try to resolve any of these issues if your unit is under warranty for these kinds of problems. Also be sure that you don’t bite off more than you can chew. There is nothing wrong with calling in an expert if you need assistance with the issues that you are having with your AC unit.

Reach Out to a Skilled AC Repair Person if You Need Help

If the simple suggestions in this guide didn’t resolve your AC issue, don’t be afraid to call for help. A skilled AC repair person will be happy to come to your home and take a look at your unit and your HVAC system itself. Getting an accurate diagnosis of the problem can help you to budget for repairs. In many cases, the fix is quite simple and it shouldn’t be long before you are able to access the help of your AC unit again.

If your AC needs to be replaced or needs extensive repairs, be sure to talk with your HVAC technician about your options. Sometimes it makes more sense to just replace your AC than to try to repair an older unit that is having issues. Being able to cool your home properly is key. Don’t wait until your AC has broken down to reach out for assistance from an experienced HVAC expert.
