You’ve invested in an air conditioner, so it’s only right that you get what you’ve paid for. It can be extremely frustrating to have a dysfunctional AC, let alone one that refuses to turn on. But don’t worry! There are many common reasons that an air conditioner won’t turn, and many of these problems have simple solutions.

With the help of our team, we’ve compiled a listing of all the reasons for why your AC may not be turning on, as well as both standard and complex solutions to your problem.

1) Clogged Air Filter

Changing your air filters is extremely important when it comes to the proper operation of your AC unit. Clean air filters ensure proper airflow. When dirt, dander, hair, dust, or other materials accumulate, the airflow becomes restricted. When your air filters are dirty, the humidity that’s normally absorbed from your home freezes and covers the coils with layers of ice. This can cause a need for immediate AC repairs. The best way to avoid this issue is changing your air filters regularly and cleaning your home frequently. 

2) Tripped Circuit Breaker

Circuit breakers were designed to shut off when they receive or detect an electricity overload. Breakers often trip when too many appliances are used at once or when a single appliance is old and uses too much electricity. When the circuit breaker trips, your AC won’t turn on. The best way to avoid this is to be conservative in your electricity and appliance usage.

3) Dysfunctional Thermostat

The thermostat for your unit serves as the control panel and acts as the most integral part of your system. If your thermostat is outdated, blank, broken, or needs batteries, it can prevent your AC from turning on. Some of these problems have simple solutions like replacing batteries or running a diagnostic test. However, in some instances, your thermostat may need to be replaced.

4) Faulty Motor

If you’ve experienced strange noises coming from your AC before it turned off completely, the issue may be a faulty motor. Capacitor tests are great at determining whether or not your motor still has some life in it. However, these tests are best left to those that are qualified in air conditioner repairs.

5) Dirty Condenser Lines

Another reason why your AC isn’t working may be due to dirty condenser lines, which get dirty the same way that air filters do. Condenser lines can be cleaned by locating your condenser unit outside of your home, lifting the lid, and using a wet or dry vac to get rid of the debris inside. Make sure to turn off the power source that feeds electricity into your AC before doing this. If this sounds too dangerous or complicated for you, contact a professional

6) Dirty Evaporator Coils

The same dirt, dust, dander, and hair can build up on your evaporator coils just as they come together in your filters or your condenser lines. Your AC is full of components that are likely to accumulate debris. This build-up can be the reason why your unit won’t turn on. You should schedule regular AC maintenance to ensure that your air conditioner is operating at its full capacity.
