Phoenix summers don’t wait — and neither should your AC. When your air conditioner won’t turn on at all, it’s more than inconvenient. In extreme heat, it can quickly become unsafe.

7 Common Reasons Your AC Won’t Turn On

Quick DIY Checks Before Calling a Pro

You can often rule out simple problems in a few minutes:

1. Check the circuit breaker — reset if tripped.

2. Inspect the thermostat — replace batteries, ensure it’s set to Cool.

3. Replace a dirty air filter to restore airflow.

4. Check the outdoor unit — clear debris and ensure the disconnect switch is on.

If your AC still won’t turn on after these steps, it’s time for a technician.

Why Professional Diagnosis Matters

Electrical issues, refrigerant problems, or component failures can’t be safely fixed without training. Attempting these repairs yourself can damage your AC or void your warranty.
