New Jersey: HVAC Replacement Cost Calculator

Most New Jersey homeowners pay between $7,500 and $13,000 to replace a central air conditioner and gas furnace together, while a standalone AC swap runs $4,000 to $7,500 installed. Labor here runs about 20% above the national baseline, with HVAC technicians earning around $37.30 an hour, so installation is a meaningful share of the final bill.

Worked example

Take a 1,900-square-foot two-story home in northern New Jersey with a 20-year-old gas furnace in the basement and a matching outdoor AC unit that finally failed. Because both pieces are at end of life and the ductwork is already in place, the homeowner replaces the pair as a single system. With mid-efficiency equipment and no major duct or electrical work, this job lands in the middle of the $7,500-$13,000 range for an AC-plus-furnace replacement — call it roughly $10,000, with the number climbing toward the top of the range for higher-efficiency, variable-speed equipment or a difficult attic or crawlspace install.

Frequently asked questions

How much does it cost to replace a furnace in New Jersey?

A gas furnace replacement in New Jersey typically runs $3,500 to $7,000 installed. The low end reflects a straightforward swap of a single-stage unit in an accessible basement, while the high end covers higher-efficiency or two-stage models and jobs that need new venting or gas line work.

Is a heat pump worth it in New Jersey's climate?

New Jersey sits in climate zone 4, where winters are cold but not extreme, and modern heat pumps handle those conditions well. Expect to pay $6,000 to $12,000 installed — more than a furnace alone, but the same equipment covers both heating and cooling, which is why many homeowners compare it directly against the $7,500-$13,000 AC-plus-furnace route.

Why is HVAC installation more expensive in New Jersey than in other states?

Labor in New Jersey runs about 20% above the national baseline, with HVAC technicians earning roughly $37.30 per hour. On a multi-day system replacement, that difference alone can add hundreds to a thousand dollars compared to a lower-cost state, even when the equipment price is identical.

What does a ductless mini split cost in New Jersey?

Ductless mini splits in New Jersey range from $3,500 to $10,000 installed. A single indoor head serving one room or an addition sits near the bottom of that range, while a multi-zone system with three or four heads covering most of a house pushes toward the top.
