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. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. Count on roughly 10 nights below 32°F and 137 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 | 1,835 |
|---|---|
| Cooling degree days / year | 3,720 |
| Nights at or below 32°F | 10 |
| Days above 90°F | 137 |
| Average low / high | 59.6°F / 80.5°F |
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 Replacement Makes Sense
- A tech found a cracked heat exchanger, or the CO detector has gone off
- The furnace is 15 to 20 years old or more
- A repair quote runs past a third of the cost of a new unit
- Gas or electric bills keep climbing even though usage hasn't changed
What Moves the Price
- Single-stage, two-stage or modulating gas valve
- New PVC venting if you move to a condensing model
- BTU size, which should come from a Manual J load calculation
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Condition of the existing ductwork and any changes it needs
- Permit and inspection fees, which the local building department sets
For Henderson we raised the national figures about 6%, 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 furnace, filter rack and thermostat wiring
- The permit and the manufacturer warranty registration
- Combustion and safety tests
- Gas line and vent connections
- Removing and hauling away the old furnace
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 the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.
- Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.

Furnace Replacement Questions from Henderson Homeowners
How much is furnace replacement in Henderson?
Plan on $3,400 to $8,300, with most jobs near $6,100. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule furnace replacement 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.
How long does a furnace replacement take?
A straight swap is usually done in one day, somewhere between 4 and 10 hours. Moving to a condensing furnace with new PVC venting can add a few more.
Is a high-efficiency furnace worth it?
In cold climates, a 95%+ AFUE furnace usually earns back the price difference in lower gas bills. Where winters are mild, the payback can take a very long time.
