Louisiana AC units work hard. Between the summer heat, pine pollen, and the occasional hurricane-season power surge, most residential systems here see more stress in one season than northern units see in three. That's why 70% of our summer calls are repair jobs — and why we keep our trucks stocked for same-day fixes on every major brand.
Common AC problems we fix every week
AC running but not cooling
Usually a low refrigerant charge, a failing capacitor, or a frozen evaporator coil. We pressure-test, leak-check, and repair — we never just 'top off' a leaking system.
AC won't turn on at all
Tripped breaker, failed contactor, dead thermostat, or burned control board. We isolate the cause in 20 minutes — not guess and replace parts.
AC blowing warm air
Restricted airflow, dirty condenser coil, failed TXV, or refrigerant issue. We'll diagnose and give you flat repair options, not a sales pitch.
Ice on the outdoor unit or lines
Low charge, restricted return airflow, or a failing blower. Never run a frozen unit — call us before compressor damage sets in.
Loud banging, grinding, or humming
Failing compressor, loose blower wheel, or debris in the fan. Loud noises almost always get worse — the sooner we look, the cheaper the fix.
Water leaking from indoor unit
Clogged condensate drain, rusted-through pan, or frozen coil. Easy fix if caught early — ceiling damage if ignored.
Our process — four steps, zero surprises
- Book in two minutes. Online or by phone. Confirmation within the hour.
- Text when we're rolling. Tech photo, live ETA, and a real window — not a 4-hour guess.
- Diagnose and quote flat. We walk you through what we found, show you the part, and quote in writing. Nothing starts without a yes.
- Fix it and back it up. Most repairs done in one visit. Every job carries a workmanship guarantee.
