AC Not Cooling in Fort Myers? Start Here

When the house starts warming up on a Lee County afternoon, these checks take a few minutes and often save a service visit.

Thermostat

Cool mode, a setting below room temperature and fan on auto. Swap the batteries if the screen is dim.

Breaker and disconnect

Check the panel and the disconnect box by the outdoor unit. Reset a tripped breaker once only.

Diagram: the disconnect box is on the wall next to the outdoor unit. It has to be on for the condenser to run.

Filter

A dark, packed filter chokes airflow and can freeze the coil. Replace it and give the system time.

Diagram: the filter sits in the air handler or behind the return grille, with its arrow pointing toward the unit.

Ice

Ice on the copper lines or air handler means switch the cooling off and run the fan to thaw it for a few hours.

Drain pan

A full pan can trip the float switch and stop the AC. That's a drain problem, not a dead system.

Diagram: water from the coil drains through a pipe. If the pan fills, a float switch can turn the AC off.

Outdoor fan

With the system calling for cool, the outdoor fan should spin. Humming without spinning needs a technician.

Write it down

Note what you checked and what happened. It helps the contractor diagnose faster.

Next step

See AC repair and send a request.

Hot afternoons

On the hottest days an older system may run nonstop and still sit a few degrees above the setting. If it catches up by evening, it may simply be at its limit; if it never does, something is wrong.
