About HVAC in Las Vegas

Las Vegas sits in the Mojave Desert, where the airport weather station records average July highs of about 104°F and December and January nights near 35°F, so air conditioning carries most of the load and heating is still needed in winter. Nevada HVAC contractors are licensed by the Nevada State Contractors Board (NSCB) under classification C-21 (refrigeration and air conditioning) or its subclass C-21B (air conditioning). The companies on this page have offices in Las Vegas, Spring Valley, Summerlin or North Las Vegas; Henderson companies have their own page. Ranked by license record and years licensed, never by payment. Checked 28 October 2026.
