Cold Harbour Heating and Air is the HVAC company North Las Vegas homeowners call when the cooling quits in July or the furnace won’t light on a January night. This city’s housing runs two very different directions: tight, energy-code-compliant homes from the mid-2000s boom in Aliante and Eldorado, and older 1980s-era tract homes near downtown with original split systems that have been baking in the Mojave sun for decades. The work here is cooling-heavy, heat-pump-heavy, and unforgiving when a unit fails during the 110°F stretches. Call (725) 726-3813 any hour, and a live person answers.
Why North Las Vegas Homes Are Different
North Las Vegas sits in the Mojave Desert, where the city sees more than 100 days a year above 100°F and humidity that rarely climbs past 15 percent. That single fact shapes nearly every HVAC job here. Cooling dominates the calendar from May through September, and because the air is so dry, systems are sized and tuned for raw temperature drop rather than dehumidification. A system that works fine in a humid climate can struggle here if the service technician doesn’t account for how heat affects refrigerant pressures at these ambient temperatures.
The housing stock makes the work more specific still. The post-2005 master-planned communities like Aliante and Eldorado are mostly tight, energy-code-compliant builds with high-efficiency heat pumps. Those homes have their own failure pattern: builder-grade installs from the boom years often shipped with missing filter dryers and kinked line sets, and many are now hitting the 12-15 year mark where those shortcuts surface. The older subdivisions around downtown North Las Vegas, nearer Nellis Air Force Base, trend toward 1970s and 1980s tract homes with aging, undersized rooftop package units. Those systems run hard through the summer and show their age in leaking evaporator coils and degraded flex duct.
Styles & brands we work with







Our Main North Las Vegas Services
AC repair and AC installation are the two calls our North Las Vegas office handles most often, with furnace repair picking up in the colder months. Each service has its own page with full pricing, repair timelines, and what to expect.
AC Repair in North Las Vegas
Most North Las Vegas AC repair calls start the same way: a system that was fine yesterday is blowing warm air today, and the forecast says 108°F. We work on every major brand and get a technician out the same day in nearly all cases. The common failures here run toward heat-related stress: capacitors that fail under sustained load, contactors that weld shut during long run cycles, and refrigerant leaks in coil connections that only show themselves when the system is pushed hardest. Every repair gets the 365-Day Done Right Promise in writing before we leave. AC Repair in North Las Vegas explains pricing and same-day scheduling in detail.

Furnace Repair in North Las Vegas
Furnace repair in North Las Vegas is less frequent than cooling work, but when the desert drops into the 30s on a winter night, a dead furnace is a serious problem. The older homes around downtown often have natural gas furnaces that sit dormant for nine months and then need attention when they’re asked to fire up again: dirty flame sensors, worn igniters, and failed inducer motors are the most common calls we see. We service Carrier, Trane, Lennox, Goodman, and Rheem systems as a matter of course. Furnace Repair in North Las Vegas covers typical repair costs and what a same-day visit looks like.

AC Installation in North Las Vegas
A new AC installation in North Las Vegas is a bigger decision here than in most cities because the system has to survive the full force of a Mojave summer. We walk every homeowner through the equipment selection, the load calculation, and the written fixed price before any equipment is ordered. The key local factor is heat pump sizing: undersized equipment in a 2,000-square-foot Aliante home will never hold temperature in August, while a unit sized for the newer neighborhoods may be wrong for a 1980s downtown home with older insulation and single-pane windows. AC Installation in North Las Vegas has full replacement pricing and what’s included.

What North Las Vegas Customers Say
"Furnace was short cycling all winter. They diagnosed a bad sensor instead of condemning the whole unit like I feared. Cheap fix, honest call."
- Russ Tiedemann"AC died overnight with a newborn in the house. They bumped us up the list and had it running by noon. I about hugged the guy. Fair price even on a rush call."
- Celeste Ngo"Honest to a fault. Two companies told me I needed a whole new unit. Coldharbour said mine had years left and just needed a cleaning and a part. Saved me thousands."
