Las Vegas Weather and HVAC Load
Las Vegas logs 1,991 heating degree days and 3,407 cooling degree days in a normal year, based on the closest NOAA weather station. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Count on roughly 11 nights below 32°F and 136 afternoons past 90°F in a typical year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 35,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 1,991 |
|---|---|
| Cooling degree days / year | 3,407 |
| Nights at or below 32°F | 11 |
| Days above 90°F | 136 |
| Average low / high | 57.7°F / 79.9°F |
Las Vegas Housing Stock
Census figures put the median build year in Las Vegas at 1994, so a typical house here has about 32 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Las Vegas has roughly 136,000 owner-occupied homes, or 55.7% of households. The median home value is $395,300, and median household income is $70,723. We use both figures to adjust labor and pricing for this page.
Clark County had 11 hail days and 41 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.5 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage.

Nevada Permits, Efficiency Rules and Rebates
Nevada is in the DOE's Southwest region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). The Southwest also sets a minimum EER2, which measures efficiency at peak heat. Plan on a mechanical permit for most replacements in Las Vegas; the contractor normally pulls it. Before you sign, ask each bidder for their Nevada license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Get one quote for a heat pump system and one for a furnace plus AC.

How often should an HVAC system be replaced?
Most systems get replaced every 15 to 20 years. AC units and heat pumps usually wear out before gas furnaces do.
Can I replace only the AC and keep my furnace?
Yes, as long as the indoor coil and blower work with the new AC. A mismatched system loses efficiency and can void the warranty.
