Niagara Falls Weather and HVAC Load
NOAA's 1991-2020 climate normals put Niagara Falls at 6,366 heating degree days and 689 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Niagara Falls put in far more hours than the air conditioner. Count on roughly 139 nights below 32°F and 6 afternoons past 90°F in a typical year. Snowfall averages about 72 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 65,000 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 | 6,366 |
|---|---|
| Cooling degree days / year | 689 |
| Nights at or below 32°F | 139 |
| Days above 90°F | 6 |
| Average low / high | 40.5°F / 58.2°F |
Niagara Falls Housing Stock
Census figures put the median build year in Niagara Falls at 1948, so a typical house here has about 78 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Owners live in 57.5% of occupied homes, roughly 13,000 households. The median home value is $104,400, and median household income is $48,535. We use both figures to adjust labor and pricing for this page.
Niagara County had 2 hail days and 16 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.5 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. In Niagara Falls, 18.8% 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.

- Furnace plus AC, or heat pump plus air handler
- Permits and electrical work
- Equipment sized to the house and climate
- Duct repair or replacement
- Thermostat and zoning upgrades
We kept the national figures close to unchanged for Niagara Falls using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover

New York Permits, Efficiency Rules and Rebates
New York falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Expect the contractor to pull a mechanical permit for a replacement job in Niagara Falls. If a bidder suggests skipping it, move on. Also ask for a New York 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
- Make every bidder quote the same efficiency ratings, or the prices won't compare.
- Ask for a duct leakage test. Leaky ducts can lose 20 to 30% of what the system puts out.
- Get one quote for a heat pump system and one for a furnace plus AC.
