Levittown Weather and HVAC Load
NOAA's 1991-2020 climate normals put Levittown at 4,591 heating degree days and 1,114 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Levittown put in far more hours than the air conditioner. On average, Levittown gets 77 freezing nights and 9 days above 90°F per year. Snowfall averages about 19 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Levittown Housing Stock
The median Levittown home dates to 1952, according to the Census ACS. That makes the typical house about 74 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 16,000 households here own their home, 93.7% of the occupied total. With a median household income of $139,696 and a median home value of $564,000, local labor rates come out above the national middle in our model.
Nassau County had 5 hail days and 20 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. Plan on a mechanical permit for most replacements in Levittown; 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.
