LAS VEGAS
HVAC company and air conditioning contractor in Las Vegas
Colton Air Conditioning is a licensed HVAC company in Las Vegas (NV license 0092120) for AC repair, furnace repair, replacement and maintenance, from older central houses to newer tracts in 89148 and beyond. Book online or call (702) 738-6976 to schedule.
Las Vegas houses are not one kind of system. A 1990s ranch near the center of town, a two-story in Summerlin, and a newer place in the southwest can all call the same number and still need a different diagnosis.
Condensers sit in full sun. Air handlers in attics pass 140°. That is why a capacitor, a packed coil, or a drain shows up as often as a dead compressor. We open the equipment before anyone talks about a new system.
What changes from one part of town to the next
Older central and east-side houses often still have the original split system, sometimes on its second or third major repair. Southwest tracts from the 2000s are hitting the age where the outdoor unit and the furnace are tired together. Newer construction is more likely to have two systems, a builder-grade air handler, and a return that was never generous.
Some smaller homes and light commercial spaces use a rooftop package unit instead of a split. If that is what is on the roof, say so when you call. It is a different service from a condenser in the side yard.
Repair, replacement, and heat
No-cool calls, furnace mornings, and full replacements are all part of the Las Vegas route. A minor part gets repaired. Replacement comes up when useful life, refrigerant, repair cost, and repeat failures say the equipment is finished. For the full list, see our HVAC services.
Summerlin, Spring Valley, Southern Highlands, Centennial Hills, and Enterprise are not the same houses. The age of the equipment and the way it was installed change the job.
In the southwest valley, Rhodes Ranch in 89148 is a good example: it was built out by several builders over many years, so neighboring houses can have very different systems.
For the northwest valley, see heating and AC repair in Centennial Hills and Lone Mountain (89149).
AC repair in Las Vegas: what usually fails, and what we check
NOAA's 1991–2020 normals for the Las Vegas airport put the average July high at 104.5°F and the average July low at 82.0°F. A Las Vegas air conditioner is not just handling a hot afternoon. It is running long cycles from the afternoon well into the night for months. That load is why the same parts fail across the valley, whether the house is a 1990s ranch near the center of town or a 2000s two-story in the southwest.
What we see most on Las Vegas AC repair calls:
- Outdoor unit not starting. The indoor fan runs, but the condenser is silent or hums. Capacitors and contactors are common failures in sustained heat. See AC outdoor unit not running.
- Running but not cooling. A clogged filter, a packed outdoor coil, a low refrigerant charge, or a failing motor can all look the same at the thermostat. See AC running but not cooling.
- Drain and coil problems in attics and closets. An attic air handler sits in serious heat, and a clogged condensate line can overflow into a ceiling or a laundry room. A musty smell from the vents often starts there. See why your AC smells musty.
When a breaker keeps tripping or there is a hot-plastic or electrical smell, a technician checks the capacitor, contactor, wiring and compressor amp draw to find the cause before the system runs again.
On the call, we test the part that is actually failing before anyone talks about a new system. A minor part stays a repair. See AC repair in Las Vegas. Heat goes the same way in winter. See heating repair and furnace repair in Las Vegas.

FAQ
How do you decide between repair and replacement?
We look at useful life, the refrigerant, whether the failure is minor or major, the repair cost next to a new system, and whether this equipment has already been a repeat problem. A minor part stays a repair.
Do all Las Vegas houses get the same diagnosis?
No. A 1990s ranch near the center of town, a two-story in Summerlin, and a newer place in the southwest can all call the same number and still need a different diagnosis. Summerlin, Spring Valley, Southern Highlands, Centennial Hills, and Enterprise are not the same housing stock.
Only the upstairs system failed. Do both get replaced?
No. In a lot of two-story Las Vegas houses the upstairs system is smaller and carries the afternoon load. We check that unit on its own. One failed system is not a reason to sell both.
What if the unit is a rooftop package instead of a side-yard condenser?
Say so when you call. Some smaller homes and light commercial spaces use a rooftop package unit. That is a different service from a condenser in the side yard.

What are the most common AC repairs in Las Vegas?
Failed capacitors and contactors that stop the outdoor unit, dirty or packed coils, low refrigerant, and clogged condensate drains on attic or closet air handlers. Long summer run times wear these parts out. See our AC repair in Las Vegas page for how we diagnose before replacing anything.
My AC runs but the house will not cool down. What should I check first?
Look at the outdoor unit to see if its fan is running. If the outdoor unit is silent or the air from the vents is not cold, schedule an AC repair visit. Running it harder will not fix a failed part.
Do you repair furnaces and heat pumps in Las Vegas too?
Yes. Las Vegas winters are mild, but NOAA normals put the average January low at the airport at 40.5°F, so heat still matters. We handle no-heat calls, flames that drop out, and heat pumps stuck on emergency heat. See heating repair and furnace repair in Las Vegas.
My furnace smells like burning on the first cold day. Should I worry?
A burning dust or oil smell the first time the heat runs each season is normal, and it can linger for a couple of days. A gas or rotten-egg smell means leave the house right away. Don't use light switches, thermostats, appliance controls or anything that could spark. Once you're outside, call 911 and Southwest Gas (877-860-6020). A hot plastic or electrical smell means turn the system off at the thermostat and schedule a furnace repair visit.
