FAQ
Why does Tampa lose outdoor AC so often?
Thunderstorm power surges trip capacitors and contactors regularly June-Sept. Surge protector ($469) prevents most of it.
Can I reset the outdoor disconnect myself?
Yes, it’s a simple switch. If it trips immediately when reset, stop and call.
Is this an emergency?
If it’s 95°F outside with kids/elderly/pets inside, yes. Call our 24/7 line. Otherwise, same-day service is usually enough.
Can I run just the indoor fan?
Fan only circulates air but doesn’t cool. OK for a few hours while waiting for repair.
How do I prevent this?
Surge protector install ($469) + annual maintenance ($249) catches capacitor wear before failure.
