Henderson Weather and HVAC Load
Henderson logs 1,835 heating degree days and 3,720 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 10 nights below 32°F and 137 afternoons past 90°F in a typical year. On the cooling side, a 2,000 sq ft house here usually needs around 4 tons. A tight, well-insulated house may get by with half a ton less.

| Nights at or below 32°F | 10 |

Henderson Housing Stock
Half the homes in Henderson were built before 2000 (Census ACS median), so the typical house is about 26 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Henderson has roughly 84,000 owner-occupied homes, or 65.6% of households. The median home value is $465,000, and median household income is $88,654. 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. In Henderson, 20.4% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.
When It Makes Sense
- Summer electric bills keep going up
- The AC is 12 to 15 years old or more
- It still runs on R-22 refrigerant
- It has had more than one refrigerant leak
What Moves the Price
- Electrical work such as a new disconnect, breaker or wiring
- The pad, permit and refrigerant (R-410A or the newer R-454B)
- SEER2 rating and whether the compressor is single-stage or variable-speed
- Tonnage, based on house size and local climate
- Whether the coil and line set also need replacing
For Henderson we raised the national figures about 38%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.
What the Quote Should Cover
- The new condenser, coil and, if needed, line set
- Startup, an airflow check and warranty registration
- The electrical disconnect and wiring
- Refrigerant charge and a leak test
- Removing the old condenser and coil
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. Expect the contractor to pull a mechanical permit for a replacement job in Henderson. If a bidder suggests skipping it, move on. Also ask for a 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 Manual J calculation. "Same size as the old one" isn't sizing.
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.
- Fall and early spring installs often come with better pricing and shorter waits.

When is the best time to schedule new AC installation in Henderson?
Between late fall and early spring. With 137 days over 90°F, Henderson contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
What size AC do I need?
