Passaic Weather and HVAC Load
In a normal year, Passaic racks up 4,734 heating and 1,255 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Passaic put in far more hours than the air conditioner. Count on roughly 89 nights below 32°F and 29 afternoons past 90°F in a typical year. Snowfall averages about 28 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.

Passaic Housing Stock
Half the homes in Passaic were built before 1938 (Census ACS median), so the typical house is 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 4,800 households here own their home, 23.5% of the occupied total. With a median household income of $56,780 and a median home value of $406,500, local labor rates come out below the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 3 hail days and 14 days with damaging thunderstorm winds in Passaic County. The largest hail reported was 1 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 Jersey Permits, Efficiency Rules and Rebates
New Jersey 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 Passaic generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their New Jersey 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.
