AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · system short-cycling on/off during Las Vegas heat waves. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — all of them need a technician to diagnose.
Banging, screaming, or grinding outdoor unit
Loud bangs · metal-on-metal screaming · grinding from the condenser during Las Vegas summers. Possible causes include a failing fan motor, worn compressor bearings, or a damaged fan blade. Turn the system off at the thermostat and call a technician.
Furnace not igniting or blowing cold
Furnace won't ignite · heat pump blowing cold air on a 40°F night · short-cycling. Las Vegas's heating season is short but cold snaps still happen. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.

HVAC in Las Vegas, NV: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Nevada licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Harry Reid International Airport (KLAS, formerly McCarran) is the NOAA reference station for the Las Vegas Valley. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00023169), Las Vegas records an annual mean temperature of 70.1°F, approximately 3,720.2 annual cooling degree days against 1,835.6 heating degree days, and only 4.18 inches of annual precipitation with just 0.2 inches of snow. The 2.0:1 CDD-to-HDD ratio defines Las Vegas as a cooling-dominated Zone 3B warm-dry desert climate where summer extremes regularly exceed 110°F and the extreme aridity imposes distinctive HVAC demands — from UV degradation of refrigerant-line insulation to attic temperatures that push 140°F during afternoon peaks.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Las Vegas city, Nevada) report 244,429 occupied housing units with a median year built of 1994. Heating-fuel distribution: 56.1% utility natural gas (137,016 units), 40.7% electricity (99,465 units), and 2,368 solar-heated homes. The newness of the housing stock has a practical HVAC consequence: most Las Vegas homes were built to post-1990 energy codes with proper R-value insulation and dual-pane windows from the start, so HVAC replacement work rarely faces the envelope-retrofit challenges common in older cities.
Nevada State Contractors Board
Every HVAC contractor working in the Las Vegas Valley must hold a current license from the Nevada State Contractors Board (NSCB). The relevant classification is C-21 Refrigeration and Air Conditioning, which falls under the NSCB’s Classification C (Specialty Contractor) category covering 42 distinct subcontracting fields. The detailed scope of C-21 work is codified in Chapter 624 of the Nevada Administrative Code. Verifying a contractor’s active C-21 license via the NSCB’s public license-lookup tool before authorizing work is the baseline due-diligence step. Permit fees for residential mechanical work are set by the City of Las Vegas Building & Safety Department; contact Building & Safety at 702-229-6251 for the current mechanical permit fee schedule. For current NV Energy PowerShift heating and cooling rebate amounts, see nvenergy.com/save-with-powershift directly. The federal Section 25C tax credit was terminated for installations after Dec 31, 2025 (OBBBA, P.L. 119-21).
