Why is my AC running but not cooling my house in Fort Myers?

If your air conditioner is running but not cooling, it could be low on refrigerant, have a dirty coil, or a clogged drain line. These are common issues in Fort Myers due to heat, humidity, and algae buildup. We offer fast diagnostics to get your system cooling again.

What should I check if my AC stops working?

Start by checking your thermostat settings, breaker panel, and drain line. If everything looks normal and your AC still won’t turn on, call Big Air AC — we specialize in fast, reliable AC repair in Fort Myers.

Why is water leaking from my indoor AC unit?

Water leaks usually mean your drain line is clogged. In Fort Myers, algae builds up quickly due to humidity. We clear clogs and install float switches or access panels to prevent water damage in the future.

Why does my AC blow warm air during the afternoon?

This can happen when your AC is low on refrigerant, overheating, or undersized for your home. Fort Myers heat puts extreme stress on systems. We’ll diagnose the issue and recommend the best solution.

What’s a normal AC temperature split in Fort Myers?

A healthy system should have a temperature split (difference between return and supply air) of 18–22°F. If your TD is low, it could mean poor airflow, low refrigerant, or a dirty coil. We measure this on every call.
