FAQ
Furnace Repair — common questions
Don’t see your question? Call 862-703-4222 — a real person answers, 24/7/365.
Do you offer emergency furnace repair?
Yes. J&M runs true 24/7/365 emergency service across Central and Northern New Jersey. Nights, weekends, holidays — if you have no heat, call 862-703-4222 and you’ll reach us, not an answering service that “opens a ticket.”
Which furnace brands do you repair?
All major residential brands, including Trane, Carrier, Bryant, Goodman, Amana, Daikin, and York. Our technicians carry common parts on the truck, which is how many repairs get finished in a single visit.
Should I repair or replace my furnace?
A useful rule of thumb: if the furnace is 15+ years old and the repair costs more than a third of a replacement, replacement usually wins long-term — especially with today’s high-efficiency models. We’ll give you the honest math for your exact situation, and we never push equipment you don’t need.
How much does furnace repair cost?
It depends entirely on what failed — an igniter is a very different job than a blower motor. What we promise: an accurate diagnosis first, a clear price before any work begins, and zero surprise charges when the job is done.
