New Brunswick Weather and HVAC Load
New Brunswick logs 5,101 heating degree days and 1,037 cooling degree days in a normal year, based on the closest NOAA weather station. Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. A normal year brings 110 nights at or below freezing and 24 days over 90°F. Snowfall averages about 29 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3 tons. A tight, well-insulated house may get by with half a ton less.

Middlesex County had 11 hail days and 36 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage.

What Moves the Price

- Whether the equipment sits in a tight attic or on a roof
- Refrigerant type and how many pounds it takes
- The part: a capacitor costs a fraction of a fan motor, and a compressor costs far more than both

New Jersey Licensing and Efficiency Rules
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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in New Jersey the company should carry a state license or registration. Ask for both.
Before You Hire
- If you see ice, shut the system off. Running it frozen can kill the compressor.
- Swap the air filter and check the breaker before you call anyone.
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
