Clifton Weather and HVAC Load
In a normal year, Clifton racks up 5,286 heating and 975 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Clifton put in far more hours than the air conditioner. A normal year brings 117 nights at or below freezing and 22 days over 90°F. Snowfall averages about 28 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.

Clifton Housing Stock
Census figures put the median build year in Clifton at 1952, so a typical house here has about 74 years on it. 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. Clifton has roughly 19,000 owner-occupied homes, or 58.7% of households. The median home value is $444,300, and median household income is $99,003. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Passaic County show 3 hail days and 14 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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. In Clifton, 18.3% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

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 Clifton 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.
