Signs your AC needs repair
Something feels off.
You don’t need to know the technical name. Start with what you’ve noticed.
Warm air from the vents
The system runs, but the house won’t cool. Common causes include a failing capacitor, a dirty outdoor coil, a refrigerant leak or attic duct trouble. Check the thermostat and filter first.
Weak or uneven airflow
Air barely moves, or one room stays hot while the rest is fine. A clogged filter, a struggling blower motor, a dirty evaporator coil or leaky ducts are common causes. If a fresh filter doesn’t help, call.
Short cycling or won’t stay on
The AC turns on and off every few minutes, or won’t start. A worn contactor or capacitor, a thermostat problem or a tripped safety switch can cause it. Repeated starts are hard on the compressor. Don’t wait.
New noises: buzzing, grinding, clicking
A new sound means something changed. Buzzing can point to an electrical part. Grinding or squealing often means a motor bearing is wearing out.
Ice on the lines or indoor coil
Ice on the refrigerant line or indoor coil usually means low airflow or low refrigerant. Switch to off or fan only and let it thaw. Then call. The ice comes back until the cause is fixed.
Water near the indoor unit
Water pooling near the air handler often means a clogged condensate drain line. Many systems have a float switch that shuts cooling off to prevent water damage, so the AC may stop too.
When to turn your AC off and call
Safety first.
Turn the system off at the thermostat and call if you notice:
- A burning smell
- A breaker that trips more than once
- Ice on the refrigerant lines
- Water pooling near the indoor unit
- An outdoor unit that hums while the fan won’t spin
If there’s ice, run the fan alone while you wait. Don’t reset a tripping breaker over and over, and don’t open the outdoor unit’s panels: capacitors can hold a dangerous charge even with the power off.
What we check during an AC repair visit
Talk through the problem.
A good AC repair starts with a diagnosis, not a guess.
- Thermostat and powerSettings, the breaker and power to the outdoor unit.
- CapacitorGives the motors their starting boost.
- ContactorThe switch that turns the outdoor unit on.
- Refrigerant pressuresSigns of a leak. Refrigerant isn’t used up, so a low charge means a leak to find. Handling it requires EPA Section 608 certification.
- Condenser fan motor and compressorThe outdoor unit’s moving parts.
- Condenser coilClean enough to shed heat.
- Filter, blower motor and evaporator coilThe indoor side of airflow.
- Condensate drain line and float switchSo water drains and cooling stays on.
Then you get the cause in plain language, and the price before any repair starts.
AC repair in East Valley homes
Built for Arizona heat.
Air conditioners here don’t get an easy season. All summer, the system runs for hours at a stretch, and that steady load is hard on parts that heat up as they work: capacitors, contactors and motors.
Where the equipment sits matters too. Many East Valley homes have the air handler in the attic, which gets far hotter than the living space in summer. Others use a closet or garage unit, and some have a rooftop package unit with everything in one cabinet on the roof.
Then there’s the monsoon, which the National Weather Service defines as June 15 through September 30. Storms bring power surges, flickers and outages, plus monsoon dust that coats the outdoor coil.
Whether you need AC service in Mesa, AC repair in Chandler or Gilbert, or a second opinion, we look at your system as it’s actually installed. Heat pump not heating? See heating services.

What affects AC repair cost
No surprises.
Every repair is priced on what your system needs. These factors move the number.
- The part that failedReplacing a capacitor and replacing a compressor are very different jobs.
- RefrigerantWhich type your system uses, and whether a leak has to be found and fixed first.
- Age and warrantySome parts may still be covered by the manufacturer’s warranty, which can depend on whether the system was registered.
- AccessAn attic air handler, a closet or garage unit and a rooftop unit each take different work to reach.
- More than one problemSometimes one failure has caused another.

AC repair questions
A few helpful answers.
How much does AC repair cost in Chandler?
It depends on what failed, your refrigerant type, how easy the equipment is to reach, and its age and warranty status. That’s why we diagnose first. Keenan explains the cause and gives you the price before any work starts.
What’s the most common AC problem in Arizona?
The usual suspects are failed capacitors and contactors, dirty filters and coils, refrigerant leaks and clogged condensate drains. Long, hot summers strain all of them. A diagnosis confirms which one you’re dealing with.
What is the 3-minute rule for air conditioners?
It’s the idea that a compressor should rest a few minutes after shutting off before restarting, because restarting too soon can damage it. Many thermostats build in the delay: Honeywell says its compressor protection can last up to five minutes. A “wait” message is usually that delay.
Should I repair or replace my AC?
If a repair reasonably makes sense, we’ll tell you. Age, repeat repairs and refrigerant type matter most. Our AC replacement page explains how we approach the replacement side.
Where does Keenan provide AC repair?
Keenan repairs air conditioners in Mesa, Chandler, Gilbert, Queen Creek and San Tan Valley. Give us your ZIP code when you call (480) 594-2665 or send a request, and we’ll confirm your address is in our area before scheduling.
Do you repair heat pumps and rooftop units?
Yes. Along with standard split systems, we repair heat pumps and rooftop package units. For a heat pump that isn’t heating, see our heating services page.
