Coldharbour Heating & Air is the HVAC company Summerlin homeowners call when they want a written price before the work starts and a repair guarantee that lasts a full year. Summerlin isn’t like the rest of the Las Vegas Valley. Homes here are newer, tighter, and built to handle desert heat, but that comes with its own set of HVAC demands. The elevation, the dust, the HOA screens around condensers, and the way the sun beats on rooftop units all change how heating and cooling equipment performs. Call (725) 726-3813 and a live person answers, day or night.
Why Summerlin Homes Are Different
Most Summerlin homes were built from the 1990s forward, which means stucco exteriors, tile roofs, and modern insulation are the standard. That’s good news for efficiency, but it also means the HVAC systems in these houses run hard. A tightly sealed home holds cool air well, but it also traps dust and puts more load on the blower motor and coils when filters aren’t changed often enough.
The elevation matters too. Summerlin sits around 3,600 feet, higher than the valley floor. The air is thinner up here, and that changes static pressure inside ductwork. A system that wasn’t sized for elevation will struggle to move air the way it should. We regularly see airflow issues in Summerlin homes where the equipment was spec’d like a valley-floor install.
Then there’s the HOA factor. Many Summerlin villages require condensers to sit behind stucco or wrought-iron screens. Those enclosures look clean, but they choke airflow. A compressor that can’t breathe runs hot, and a hot compressor fails early. Any honest HVAC tech in Summerlin checks the enclosure before anything else. Dust off the desert does the rest: dirty coils, clogged filters, and faster wear on outdoor components. This is the one market in the valley where filter changes every 30 to 45 days are genuinely necessary, not just recommended.
Styles & brands we work with







Our Main Summerlin Services
Summerlin homeowners call us most about two things: air conditioning that quit in July and furnaces that won’t light on a cold December morning. Each service has its own Summerlin page below.
AC Repair in Summerlin
An AC that stops cooling in Summerlin is a health issue, not an inconvenience. With summer highs routinely crossing 105°F, a failed compressor or a blown capacitor can turn a house dangerous by late afternoon. We diagnose the problem, hand you a written price, and repair it. Capacitors, contactors, fan motors, refrigerant leaks, and compressor failures are all in our wheelhouse. The desert dust shortens the life of electrical components here, so we carry common Bryant, Carrier, and Trane parts stocked locally. Read more on our AC Repair in Summerlin page.

Furnace Repair in Summerlin
Summerlin nights drop fast. A furnace that won’t fire in December leaves a house cold by midnight. We repair igniters, flame sensors, gas valves, blower motors, and control boards. The same dust that coats AC coils in summer settles into furnace burners in winter, so seasonal cleaning matters here. Most furnace repairs in Summerlin run $150 to $700, and every one comes with the 365-Day Done Right Promise in writing. Details on our Furnace Repair in Summerlin page.

AC Installation in Summerlin
Newer Summerlin homes with multi-zone and smart thermostat setups need careful load calculations, not guesswork. A replacement AC in Summerlin typically runs $3,500 to $7,500 depending on tonnage, efficiency tier, and ductwork condition. We write you a fixed price before any equipment arrives, and we schedule a firm install date. No same-day promises on installs; this is ordered, permitted, and commissioned properly. More on our AC Installation in Summerlin page.

What pushes a Summerlin job toward the top of these ranges is usually access. Attic installs take longer when the pull-down ladder is in a hot garage, and HOA condenser screens add labor. Whatever the number, you get it in writing before a single tool comes out. The Kingswell Way means the price we quote is the price you pay, period.

What Summerlin Customers Say
"Thermostat kept losing its mind. He swapped it, showed me how to use the new one, and didn't charge for a bunch of extras. In and out, friendly, done."
- Paula Kingston"New mini split for the addition. Clean install, on time two days running, and the price matched the written quote to the dollar."
- Yvonne Prewitt"AC quit on the hottest day of the year of course. Coldharbour had a tech out that evening, found a bad capacitor, and had us cool again within the hour. Charged the quote, not a penny more."
