AC repair in Summerlin

Book online or call (702) 738-6976 to schedule.
Checks before you call
- Breaker on. If it trips again after one reset, leave it off. See AC tripping breaker.
- Warm air only: check the mode first. See AC blowing warm air.
Upstairs failed, downstairs fine
If your home has two systems, they're separate machines. We test the one that failed and measure its temperature split before anyone calls it a new air conditioner. The other system is a separate decision. See two-story temperature balance and AC not keeping up.
Side-yard condensers
If your condenser sits in a side yard with a long line set back to an attic or garage air handler, a replacement is planned for the spot the equipment already uses. Keep plants and stored items back from the coil. See dirty AC coil.
Age alone isn't a reason to replace. Useful life, refrigerant and repair cost decide it. See repair or replace an old AC, AC repair in Las Vegas and AC replacement in Las Vegas. Already have a quote? See HVAC second opinion.
Furnace repair in Summerlin
Short answer: Summerlin climbs toward the Spring Mountains. USGS puts sample points at about 2,480 feet on the east side, 2,700 feet in the middle and 3,020 feet on the west side, versus about 2,100 feet at the Harry Reid airport weather station. Gas furnaces above 2,000 feet must be derated for altitude, so the higher your house, the more the setup matters. Book online or call (702) 738-6976 to schedule.
If you smell gas, 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). Don't flip switches or try to relight anything. If a CO alarm sounds, get everyone outside and call 911.
Why elevation matters
NFPA 54 says gas appliance input ratings apply up to 2,000 feet. Above that, input is reduced by 4% per 1,000 feet or per the manufacturer's instructions. At 3,000 feet, that's about a 12% reduction. We check gas pressure and orifice setup against the manufacturer's altitude instructions, not just whether the burners light. NOAA publishes Las Vegas normals at the airport only. Its January average low is 40.5°F. There's no official figure for Summerlin.
Where the furnace is
An attic furnace needs a clear passageway, a light and a service receptacle (IRC M1305.1.3). A closet or garage furnace needs combustion air (IRC G2407), so keep the space clear. If the outdoor unit heats and cools, you have a heat pump; see heat pump not heating, heat pump emergency heat and heat pump defrost mode (steam in winter is usually defrost).
Checks before you call
- Furnace switch on, blower door seated.
- Breaker reset once. If it trips again, leave it off.
Then see heater not working, furnace flame sensor and furnace short cycling. For the full process, see furnace repair in Las Vegas and heating repair.
If the furnace still won't heat after these checks: Book online or call (702) 738-6976 to schedule.

Summerlin is a master-planned community on the west edge of the valley, named for Jean Amelia Summerlin, Howard Hughes's grandmother. Its first neighborhood, park and school were finished in 1990, and new villages are still going up toward the mountains. That shows up in the equipment. One street can have a system from the 1990s, and the next can have one that's a year old. We diagnose what's in your house, not what the neighborhood is known for.
Most of Summerlin is inside the City of Las Vegas. Summerlin South, south of Charleston Boulevard, isn't. Clark County describes it as an unincorporated town administered by the county, so the county, not city hall, handles its zoning and permits. When a replacement needs a permit, it goes to the City of Las Vegas or to Clark County, depending on which side of that line the house sits. See HVAC permits in Las Vegas.
Summerlin has community associations for its north, south, west and center areas. Sun City Summerlin, Siena and Red Rock Country Club have their own, and many villages have an HOA as well. If you plan to move or add an outdoor unit, ask your association about its review process first. For a guard-gated community, add Colton Air Conditioning to your gate guest list for the appointment day and tell us which entrance to use.
Heat pumps in Summerlin
If the outdoor unit heats and cools, it's a heat pump, and the visit covers both sides: the cooling circuit, plus the reversing valve, defrost and backup heat. A short burst of steam from the outdoor unit on a cold morning is usually defrost. Backup heat that stays on through a mild afternoon isn't normal and is worth a visit. See heat pumps and heat pump emergency heat. Book online or call (702) 738-6976 to schedule.
