Rochester Housing Stock
The median Rochester home dates to 1938, according to the Census ACS. That makes the typical house about 88 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 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
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Rinse the indoor filters once a month during heavy use.
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
