AC and Furnace Repair Cost in New Jersey
AC and furnace repairs in Union County run $150 to $5,500, based on the ranges Vanguard's Instant Estimator quotes. A capacitor or thermostat sits at the bottom of that span. A compressor or heat exchanger sits at the top. The part that failed sets most of the price. Here is what each repair level covers and when replacement deserves a look.
Typical price ranges
Minor repair
$150 to $650
Quick fixes such as a capacitor, contactor or thermostat replacement, or a refrigerant top-off. This is the range Vanguard's Instant Estimator quotes; the final price is confirmed in writing on site before work starts.
Moderate repair
$400 to $1,400
Component work such as a blower motor, control board, heat pump reversing valve or refrigerant leak repair. These are the Instant Estimator's figures; the final price is confirmed in writing on site before any work begins.
Major repair
$1,200 to $5,500
Significant failures such as a compressor, a heat exchanger or full condenser work. This is what the Instant Estimator quotes at this level; the final price is confirmed in writing on site before work starts.
What drives the price
- What failed
- A capacitor or contactor is a small part and a short job. A compressor is the most expensive part of an AC system, and a heat exchanger is the core of a furnace. The diagnosis sets the price more than anything else.
- Refrigerant type
- Older systems that use R-22 refrigerant cost more to recharge. Adding refrigerant without fixing the leak only buys time.
- System age and condition
- On an older system, one repair can expose other worn parts, and parts for discontinued equipment can be harder to find.
- Access
- Equipment in an open basement is quicker to work on than an air handler in a tight attic or crawl space.
Repair or replace?
Compare the repair with the replacement figures. In the estimator, a new gas furnace starts at $3,500 and a new central AC at $4,500 for a home under 1,800 sq ft. A major repair near the top of the $1,200 to $5,500 range can match or pass those numbers.
On a furnace, a cracked heat exchanger is a safety issue and usually means replacing the furnace rather than repairing it.
How the price is set
A technician finds the cause first, then you get a written price before any work starts, with no hidden fees. Ask when you book whether a diagnostic charge applies to your visit. The work is done by Vanguard's own licensed technicians under NJ HVACR license 19HC00609600, not subcontractors.

Frequently Asked Questions
How much does AC repair cost in NJ?
Vanguard's Instant Estimator quotes $150 to $650 for minor AC repairs such as a capacitor or contactor, $400 to $1,400 for component work such as a blower motor or refrigerant leak repair, and $1,200 to $5,500 for major failures such as a compressor.
How much does furnace repair cost in NJ?
Furnace repairs use the same estimator ranges. A thermostat replacement falls in the $150 to $650 range, a blower motor or control board in the $400 to $1,400 range, and a heat exchanger in the $1,200 to $5,500 range.
Why not just add refrigerant?
An AC system is sealed, so low refrigerant almost always means a leak. A top-off, in the $150 to $650 range, restores cooling for a while, but the leak is still there. Leak repair falls in the $400 to $1,400 range.
Is it worth repairing an older AC or furnace?
For a minor fix such as a capacitor, usually yes. For a major repair in the $1,200 to $5,500 range, compare it with the replacement starting prices in the Repair or replace? section before you approve it.
