Rochester Weather and HVAC Load
In a normal year, Rochester racks up 6,272 heating and 677 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Rochester put in far more hours than the air conditioner. A normal year brings 129 nights at or below freezing and 8 days over 90°F. 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.

Rochester Housing Stock
The median Rochester home dates to 1938, according to the Census ACS. That makes the typical house about 88 years old. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. About 34,000 households here own their home, 37.2% of the occupied total. With a median household income of $46,628 and a median home value of $120,600, local labor rates come out below the national middle in our model.
Monroe County had 5 hail days and 31 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.

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. Plan on a mechanical permit for most replacements in Rochester; the contractor normally pulls it. Before you sign, ask each bidder for their 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
- A combi boiler frees up space and replaces your water heater.
- Ask your gas or oil company about rebates on condensing boilers.
- For a steam system, hire a contractor who works on steam regularly.
