Irondequoit Weather and HVAC Load
NOAA's 1991-2020 climate normals put Irondequoit at 6,272 heating degree days and 677 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Irondequoit put in far more hours than the air conditioner. Count on roughly 129 nights below 32°F and 8 afternoons past 90°F in a typical year. Snowfall averages about 102 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 | 6,272 |

Irondequoit Housing Stock
Half the homes in Irondequoit were built before 1955 (Census ACS median), so the typical house is about 71 years old. 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. About 18,000 households here own their home, 79.1% of the occupied total. Homes here have a median value of $169,000 and households a median income of $76,871. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 5 hail days and 31 days with damaging thunderstorm winds in Monroe County. The largest hail reported was 1.25 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 Irondequoit, 22.2% 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.

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 Irondequoit. 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.
