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, and furnaces and heat pumps in New Brunswick put in far more hours than the air conditioner. A normal year brings 110 nights at or below freezing and 24 days over 90°F. Snowfall averages about 29 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.

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.
Symptoms Worth a Service Call
- The burners light, then shut off a few seconds later
- Cold air coming out of the vents
- A yellow or flickering flame instead of a steady blue one
- The blower won't stop running
- Banging, squealing or rattling from the furnace
What Moves the Price
- Whether the part is still under the manufacturer warranty
- The diagnostic or service call fee
- The furnace's age and brand, which affect parts availability
- Night, weekend or holiday rates
- Which part failed: a flame sensor costs far less than a control board or blower motor

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
- Ask whether the diagnostic fee comes off the repair bill.
- Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
- If the furnace is past 15, ask the tech to price both a repair and a replacement.
