It is frustrating when your AC won’t turn on. Here are five common reasons why this happens.

1. Thermostat Problem

If your AC is not turning on, first check the thermostat. Make sure the display is working, and try replacing the battery. If it still isn’t working, have an HVAC technician look at it. There may be an electrical problem, and a new thermostat will need to be installed.

2. Circuit Breaker is Tripping

A tripped circuit breaker will result in your AC unit not turning on. And, you shouldn’t keep flipping the switch for the AC system, as this can result in an electrical fire. Leave the AC off and have a technician diagnose the problem.

3. Refrigerant Leak

If your AC unit outside is not turning on, it could be because it is leaking refrigerant. When the refrigerant level is too low, it can’t cool your home. You will need a professional technician to resolve this problem. They will find the leak, fix it and recharge the refrigerant according to the AC manufacturer’s specifications.

4. Dirty Condenser

The condenser in the AC outdoor unit collects dirt, dust and other debris over time. It needs to be cleaned annually to do its job. You should schedule AC tune-ups in the fall so a technician can thoroughly clean your AC system and make sure everything is working as it should.

5. Wiring Problem

The wires that connect the outdoor AC unit to your home may break down over time. Or a connection has come loose. A technician can fix these problems for you.
