When that warm Texas weather hits, there is nothing as important as properly working air conditioning. Your AC unit is essential to staying comfortable in the Texas summer. So, what happens when your beloved air conditioning unit stops working and starts blowing warm air instead of cold air? There are a few common issues that can lead to this problem and cause your AC unit to start blowing out hot air instead of cold.

Problem with Your Thermostat

Before you start troubleshooting different issues with your actual AC unit, take a look at your thermostat. This is a very common issue and one that is simple to fix. The first thing you should do is turn your thermostat on and off to see if resetting it fixes the problem.

Dirty Coils

If you have a dirty evaporator coil or a dirty condenser coil, it can cause the air in your AC system to come out warm. This is a common side effect of issues with dirt, dust, and debris getting caught in the system. Start by turning off the AC unit and inspecting everything visually. If you see dust build-up or debris, carefully remove it. If not, then it is time to call a professional for help.

In addition to cleaning out the coils at the moment, your HVAC professional can get you on a maintenance routine so that you can avoid this problem in the future.

Low Refrigerant

The refrigerant is one of the most important components of your AC unit. The refrigerant is designed to absorb heat and leave the air in your unit nice and cold. So, if your refrigerant is too low, then your system won’t be able to cool any air that goes through the system.

When your AC unit has low refrigerant levels, it is typically a sign of a malfunction or leak in the system. Sometimes, it may take a while to realize there is a refrigerant issue, but in some cases, there may be ice forming on the outside of your condenser. If you suspect this is the issue, call an HVAC professional right away. Refrigerant is toxic and should never be touched by anyone who isn’t a trained HVAC professional.

Circuit Breaker Issues

Your HVAC system requires a great deal of electricity, so if you have a blown or broken circuit breaker, it can cause different components to break and to stop the cooling mechanism in your air conditioning unit. If you have to keep checking the circuit breaker or turning it on with your AC unit, there is likely a larger electric issue going on with your system.
