What affects the price of a furnace repair?
- Age of the furnace. Parts for units older than 15 years are often discontinued and require aftermarket sourcing, adding $50-$150.
- Access. Attic and crawlspace jobs add 15-30 minutes of setup and can add $75-$125.
- Emergency vs scheduled. Thermal Touch does not charge weekend or after-hours premiums, but many NJ shops add $75-$200 for evening or weekend calls.
- Diagnostic vs repair. Some issues need a second visit for parts, which we quote transparently rather than up-charging.
When furnace repair is not worth the money
The rough rule: if the repair costs more than 40% of a new furnace ($4,500-$8,000 installed in NJ), replacement usually pays back inside 3 years through efficiency gains. According to the U.S. Department of Energy, a modern 96% AFUE furnace uses 30-40% less gas than a pre-2005 80% AFUE unit.
A cracked heat exchanger, more than 2 failed high-cost parts in 12 months, or a furnace over 20 years old are all signs to price a replacement instead of pouring money into repairs.
Frequently asked questions
Thermal Touch HVAC charges $125 for a service call, which includes the diagnostic. That fee is waived if you approve the repair on the same visit. Return visits are $75. Most NJ shops charge $89-$150 for the service call, with wide variance in whether they waive it.
For repairs under $500, we typically bill on completion. Repairs over $500 require a 20% parts deposit, which is standard practice across NJ. We accept Cash, Credit Card, Apple Pay, and Zelle.
No shop that gives a real diagnostic estimate does it for free. What some call a free estimate is a walk-through and eyeball, not real diagnosis. Thermal Touch charges $125 for actual diagnostic work, waived when you approve the repair.
