AC Not Turning On in West Palm Beach, FL?
When your AC will not turn on at all, it can feel like an emergency in South Florida heat.

Frequently Asked Questions
Why did my AC suddenly stop turning on?
Sudden no-start problems are often tied to breakers, thermostats, drain safety switches, capacitors, or control issues.
Can a clogged drain line shut my AC off?
Yes. Many systems have a safety switch that shuts the system down when the drain line backs up.
Should I reset my breaker if the AC will not turn on?
You can try once, but if it trips again, stop and call for service because repeated trips can signal an electrical problem.
Is this usually an expensive repair?
Sometimes it is a simple fix, but the only way to know is to test the system and identify the failed component.
