What we fix
Tell us the symptom in plain English. We diagnose first, quote before we touch anything, then fix it right.

Thermostat's calling for cool and nothing happens. Usually a capacitor, contactor, or control board, and we carry the common parts on the truck.
Get it fixed
Air's moving but it isn't cold. Could be low refrigerant, a frozen coil, or a failing compressor. We find the real cause before quoting a fix.
Get it fixed
Puddles by the air handler or a stain on the ceiling mean a clogged drain line or a rusted-out pan. We clear it and stop the damage.
Get it fixed
Grinding, buzzing, or a musty smell when it runs. We track it down instead of guessing, so you don't pay for parts you don't need.
Get it fixed
The system kicks on and off every few minutes and never really cools. It's hard on the equipment and your bill. We'll diagnose why.
Get it fixed
A system that's low on charge or running worn parts works overtime. A repair often pays for itself in what it saves you every month.

Repair questions
Same day in most cases. A real person answers 24/7, seven days a week, never voicemail, and we run techs after hours in summer. If your system can't be fixed tonight, we keep spot coolers on hand so you can still sleep cool.
You pay one flat diagnostic fee, then we hand you a written repair quote before any work starts. No surprise line items and no work you didn't approve. We give you a repair quote at any system age, even on an old unit.
We diagnose first and tell you straight. If a repair buys you real time, we'll say so, even when it's the cheaper answer. We only bring up replacement when the math clearly favors it, and we show you the numbers either way.
Yes. We service every major brand, from Carrier and Trane to Rheem, Goodman, Lennox and Daikin, no matter who put the system in.
No. Our NATE-certified techs repair to manufacturer spec, which is exactly what keeps a parts warranty valid. If your system is still under warranty, we'll check coverage before quoting.
Yes, a real person, 24/7. While a lot of "24/7" competitors roll to voicemail after 5, we actually pick up and dispatch on nights, weekends and holidays.
Because moving air and cooling air are not the same thing. The blower can push plenty of air while a thermostat, outdoor unit, frozen coil, or refrigerant problem keeps the system from actually pulling heat out. That's the kind of thing we test on site instead of guessing at.
No. Turn cooling off and set the fan to on so the ice can thaw. Running a frozen system keeps cooling poorly, can make the problem worse, and makes the real cause harder to find. Once it thaws, we can check whether the culprit is airflow, a dirty filter, or the refrigerant side.
One reset is fine if it clearly tripped. If it trips again, stop. A breaker trips to protect the system and your home, and repeated resets can hide a failing motor, weak capacitor, or wiring fault and add real risk. If it keeps going, shut it off and call us.
Same-day service, honest diagnostics, and a real person on the phone 24/7. Your comfort is one call away.
