Your air conditioner sees heavy usage during the hottest months of the year. So when your air conditioner breaks, the house can quickly become unbearable. If your AC is no longer turning on, an HVAC contractor can help troubleshoot and fix the system, but it's still good to understand potential causes so you can prevent future problems. 

Why Won't My Air Conditioner Turn On?

1. Power Issues 

The most obvious reason your AC may not be turning on is if it's unable to receive power. The cause could be a tripped circuit breaker, which can happen if too many appliances are plugged in. If so, try unplugging other items with high power demands and resetting the breaker.

2. You Need a New Air Filter

Your air conditioner's air filter is important for filtering out particles. However,  if it's not changed every month, it can become clogged with excess dirt and debris over time. When it's sufficiently clogged, air will no longer be able to flow effectively. This, in turn, can cause your air conditioner to freeze. An HVAC contractor can troubleshoot your system to see if this is the issue, as well as change the air filter and recommend a maintenance schedule. 

3. Failed Motor

Your air conditioner uses a motor to power the condenser fans. If the motor is no longer functioning, the air conditioner won't work. When the motor has degraded, you can typically hear a difference when its running, and it could make unexpected noises.

4. Thermostat Issues

The thermostat lets the HVAC unit know when to kick on. If it's experiencing issues, then it may be misreading the internal temperature so the AC won't turn on. Make sure the thermostat is powered on and showing something on the display. If not, an HVAC contractor can help install the correct replacement for your system.
