About HVAC in Henderson
Henderson sits at the south-east edge of the Las Vegas Valley, where the nearby Las Vegas airport 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). Every company on this page has its office in Henderson. Ranked by license record and years licensed, never by payment. Checked 27 October 2026.
