New HVAC installation in Las Vegas demands expertise in extreme-heat-climate equipment selection and sizing. The Las Vegas Valley's solar gain, desert heat, and high ambient temperatures create cooling loads that require properly-sized, high-SEER2 equipment rated for operation in extreme heat conditions. Most Las Vegas new installations specify high-efficiency central AC with gas or electric heat — standard heat pumps are generally not recommended given summer ambient temperatures exceeding 110°F. New system costs in Las Vegas run $5,500–$18,000. All work requires an NSCB-licensed contractor and a Clark County or city mechanical permit. Nevada NSCB-licensed contractors below serve Las Vegas, Henderson, North Las Vegas, Summerlin, Green Valley, and Boulder City.
