AC Went Out in Florida Summer? Do These Five Things First

Before you call, check these five things — they resolve roughly 20% of emergency calls for free. Then here's what happens when you call us.

Florida humidity makes HVAC its own discipline. The same equipment that performs well in Atlanta or Charlotte will leave a Jacksonville house sticky if it isn't tuned for the climate.

The symptom

The complaint usually comes from comfort, not equipment. By the time someone calls us, the system has been struggling for weeks.

How we diagnose

Static pressure, supply temperature, return temperature, and indoor RH. None of these by themselves tell the story — together they almost always do.

What we typically change

Across recent service tickets in this category, we ended up changing duct sizing, adding a dehumidifier, or downsizing equipment. We rarely "just" repair the original problem when humidity is involved.
