What causes an air conditioner to stop working near O’Fallon?

If your air conditioning unit is not working, there might be a number of reasons why. Some common reasons why include:

Tripped circuit breaker - Air conditioners typically have an indoor and an outdoor circuit breaker. Make sure your outdoor breaker is not tripped. If you reset it and it trips again, you will need to contact a professional to determine what is wrong.
Dirty evaporator coils - Dust, dirt and dander can build up on evaporator coils and can cause a total breakdown of the system. Regular AC maintenance can help prevent this from happening.
Dirty condenser lines - Over time, mold and algae can grow on condenser lines, clogging them and causing the air conditioning unit to malfunction.
Faulty motor - If the unit had been making unusual sounds before it stopped working, the motor is probably broken.
Broken thermostat - If the thermostat is not working properly, it can stop the air conditioner from turning on.
