AC Repair in Gilbert, AZ
Every make and model. A $120 diagnostic, waived when you go ahead with the repair.
AC not cooling? Here's what happens when you call
Your house is getting warmer by the hour and the thermostat says the system is running. Call (480) 808-9990 or book online, and we'll send a licensed technician to your Gilbert home. Same-day visits depend on the schedule, and emergency dispatch runs 24/7.
The technician tests before replacing anything: electrical readings on the capacitor and contactor, airflow across the coil, and refrigerant pressures when the symptoms point that way. You hear the cause in plain terms and get a written price for the fix. The diagnostic is $120, and we waive it when you go ahead with the repair.

Common AC problems in Gilbert homes
- A failed capacitor. A summer of 110-degree afternoons wears them out, and then the outdoor fan or the compressor won't start.
- A dirty condenser coil. Monsoon dust packs into the fins and the system can't get rid of heat.
- A frozen evaporator coil, usually from a clogged filter or low refrigerant.
- A clogged condensate line on an attic air handler. The safety switch trips and shuts the system off so water doesn't come through your ceiling.
- A worn contactor or a fan motor with failing bearings.
Each of these needs a different fix. Adding refrigerant won't repair a leaking coil, and a new capacitor won't save a motor that's seizing. Finding the actual cause the first time is how you avoid paying twice.
Older systems and R-22
If your system went in before 2010, look at the data plate on the outdoor unit. Many from that era use R-22, a refrigerant that hasn't been produced or imported in the U.S. since 2020. What's left is expensive, so recharging a leaking R-22 system often isn't worth it. We'll show you the repair price next to a free estimate for a new system and let you decide. If a repair makes sense, that's what we'll recommend.
Before you call
Check the thermostat batteries and settings, and make sure the breaker hasn't tripped. Then look at the filter. A clogged one can freeze the coil and shut everything down. If the system runs but blows warm air, or the outdoor unit is grinding or clicking, turn it off at the thermostat and call us. Letting it run can turn a capacitor job into a compressor replacement. And if the house is getting dangerously hot, get everyone somewhere cool first.
