Home › Las Vegas

Las Vegas runs hot: summer highs sit above 100°F for weeks at a stretch, and an air conditioner here isn't a comfort — it's safety equipment. Most homes in the valley run a rooftop or split-system unit hard for six months a year, so Las Vegas HVAC contractors see some of the heaviest cooling workloads in the country.

The valley's housing stock spans 1950s ranch homes near downtown, 1990s stucco subdivisions in Spring Valley and Summerlin, and new builds still going up on the edges. Older homes often need ductwork and insulation attention alongside a unit swap; newer homes more often need warranty service and smart-thermostat work.
