The diagnostic visit is $95 to $175 and comes off the repair. This guide lists the price for each fix, what to check before you call, and the one repair you should never pay for.
Before you call, check these
- Thermostat set to Heat and above room temperature, and the batteries
- Furnace power switch (looks like a light switch on or near the unit) is on
- Breaker in the panel
- Air filter: a clogged filter trips the high-limit switch and shuts the furnace off
- Gas valve handle in line with the pipe, and other gas appliances working
- For oil: the tank gauge and the red reset button on the burner, pressed once only

The repair you should never pay for
A cracked heat exchanger on a furnace over 10 years old. The part is most of the price of a new furnace, and a cracked exchanger can leak carbon monoxide into the house. If a technician condemns your heat exchanger, ask to see the crack with a camera, then get a replacement price. Our furnace and boiler replacement guide has the 2026 numbers.
Repair or replace
Same rule as AC: repair cost times the furnace's age. Over $5,000, replace. Under 12 years old and the fix is under $700, repair. Furnaces in NJ last 15 to 20 years for gas and 20 to 25 for boilers with yearly service.
No heat in winter
No heat with an infant, an elderly person or a temperature under 20°F is an emergency, and we treat it as one. The 24/7 line reaches a dispatcher, and the crew brings the common parts so most no-heat calls are fixed on the first visit. Read our no-heat checklist for what to do while you wait.
