AC Repair Las Vegas

Published by Colton Air Conditioning, NV license 0092120

Short answer: Colton Air Conditioning repairs central air conditioners and heat pumps in homes across the Las Vegas valley. We diagnose first and fix the failed part when it's a minor failure. Replacement only comes up when the system is finished. Open 24 hours, 7 days. Book online or call (702) 738-6976 to schedule.

What Las Vegas heat does to an air conditioner

NOAA's 1991–2020 normals for the Las Vegas airport station put the average July high at 104.5°F and the average July low at 82.0°F. With nights that warm, a condenser can run long cycles well into the evening. Heat and run time wear down the electrical parts first: capacitors, contactors and condenser fan motors. That's why most no-cool calls we see are those parts, not a dead compressor.

How the visit works

1. We start with what you noticed and when it started.
2. The technician tests the electrical side: capacitor, contactor, fan motor and compressor draw.
3. Refrigerant is checked with gauges against the manufacturer's target. If it's low, we look for the leak.
4. You hear the finding and your options before any part goes in.
5. If replacement is on the table, we explain why: age, refrigerant type, repair cost and the failure itself. See repair or replace an old AC.

The parts behind most no-cool calls

Our job records point to the same short list of parts again and again. Each one has a job to do, and each one fails in its own way.

Run capacitor. It gives the compressor and condenser fan motor the push they need to start and keep turning. A weak one can leave the outdoor unit humming without the fan spinning. The technician measures it against the rating printed on its label.

Contactor. This is the switch in the outdoor unit that sends power to the compressor and fan when the house calls for cooling. Valley heat and years of cycling pit its contact points until power stops getting through cleanly.

Condenser fan motor. It pulls air across the outdoor coil so the system can shed heat. When the motor stops, pressures climb and the unit shuts down on safety controls, or the compressor runs hot.

Transformer. It steps line voltage down to 24 volts for the control circuit. When it fails, the indoor and outdoor units both sit silent because nothing is telling them to run.

Condensate drain. Cooling pulls water out of the air, and the drain carries it away. A sagging or poorly pitched line backs up, and many systems have a float switch that stops cooling to protect the ceiling.

None of these is a reason to replace a working system. Each one is tested, confirmed, and replaced as a single part. Book online or call (702) 738-6976 to schedule.

AC repair FAQs

What's the most common AC repair in Las Vegas?

In our own records, the most common are capacitors, contactors and condenser fan motors. They're parts that heat wears out, and they're single-part repairs. See AC capacitor failure.

My AC uses R-22. Can it still be repaired?

Often, yes. The EPA ended R-22 production and import in 2020, so a leak on an R-22 system is a bigger decision than on a newer one. We'll tell you what the leak means for your system. See AC refrigerant leak.

Does a no-cool call mean the compressor is gone?

Rarely. In our records, a compressor replacement is far less common than capacitor, contactor and fan motor repairs.

Do you repair heat pumps too?

Yes. A heat pump's cooling side is an air conditioner, and we repair both sides. See heat pump repair.

Which parts of the valley do you cover?

Las Vegas, Henderson, Spring Valley, Enterprise, Southern Highlands, Summerlin and nearby areas. The repair happens at your house. Our 6545 S. Fort Apache Rd Ste 135 #467, Las Vegas, NV 89148 address is for mail only.

Are you licensed?

Yes. Colton Mechanical LLC holds Nevada contractor license 0092120.

What is a hard start kit, and does my AC need one?

A hard start kit adds extra starting torque so the compressor can get going against high pressure on a hot afternoon. We fit one only when testing shows the compressor straining to start, as we did on a job in ZIP 89074 in October 2026. It helps a healthy compressor; it can't save a failing one.

Can a bad transformer keep my AC from turning on?

Yes. The transformer powers the 24-volt control circuit that tells the indoor and outdoor units when to run. When it fails, the whole system goes quiet even though the breaker is on. The technician tests its output and looks for the short that took it out, so the new one doesn't fail too.

Why did the same AC part fail again?

A repeat failure usually means something else is stressing that part. A weak capacitor can overwork a fan motor, low supply voltage can burn contacts, and a blocked outdoor coil makes everything run hotter. On a repeat call, the technician looks for that cause before replacing the part a second time.
