Yonkers Weather and HVAC Load
Yonkers logs 5,119 heating degree days and 917 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here, and furnaces and heat pumps in Yonkers put in far more hours than the air conditioner. Count on roughly 109 nights below 32°F and 19 afternoons past 90°F in a typical year. Snowfall averages about 33 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 60,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Yonkers Housing Stock
The median Yonkers home dates to 1958, according to the Census ACS. That makes the typical house about 68 years old. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. About 38,000 households here own their home, 47.2% of the occupied total. The median home value is $478,000, and median household income is $81,816. We use both figures to adjust labor and pricing for this page.
Westchester County had 6 hail days and 33 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.5 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.

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. Equipment replacements in Yonkers generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their New York license or registration number and a certificate of insurance with the quote. 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 a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- Ask your gas or oil company about rebates on condensing boilers.
- A combi boiler frees up space and replaces your water heater.
