The calculator uses 2026 North Jersey installed price ranges from jobs across Passaic, Bergen, Essex, Union, and Hudson counties. North Jersey runs meaningfully higher than the NJ average — NYC-metro labor rates are what they are. Here's what moves you within (or past) the range:
Home size sets the equipment size. A 1,200 sq ft cape might take a 1.5–2 ton AC and a 60,000 BTU furnace; a 3,000 sq ft colonial can need 4–5 tons and 100,000+ BTU. Bigger equipment costs more — but oversizing "just in case" is a mistake: an oversized AC short-cycles, leaves the house clammy, and dies young. We size with real load calculations, not rules of thumb.
Efficiency tier typically adds 25–40% upfront. An 80% AFUE furnace wastes 20 cents of every dollar of fuel; a 96% unit wastes four. The payback is fastest in homes that heat all winter and in houses with high utility bills. High-efficiency systems can also qualify for NJ Clean Energy Program rebates (up to $2,000 for qualifying heat pumps, $700 for 95+ AFUE furnaces) and federal tax credits up to $2,000 — we'll tell you what's available when we quote.
Ductwork is the wildcard. North Jersey homes built in the 1950s–70s often have ducts sized for heating only, or duct runs that leak 20–30% of the air into the crawlspace. We inspect your ducts on every replacement quote and show you photos. Sometimes a few hundred dollars of sealing is enough; sometimes the honest answer is that the ducts need to go.
Site extras — a full electrical panel upgrade, new refrigerant lines, rerouted venting, oil-tank removal for oil-to-gas conversions — are where "surprise" costs come from with other companies. Our quotes list everything upfront, and the price we agree on is the price you pay.

How much does it cost to replace an HVAC system in NJ?
In North Jersey in 2026, a full furnace-plus-AC replacement typically runs $9,500–$16,000 installed. A furnace alone runs about $5,000–$10,000 and central AC alone about $5,500–$12,000, depending on home size, efficiency tier, and whether ductwork is needed. See the full furnace cost breakdown →
Is the calculator's estimate a real quote?
No — it produces a realistic planning range, not a quote. Every home differs: duct condition, electrical panel, gas line availability, venting, and refrigerant lines all change the final number. Call (973) 653-8456 for a free in-home estimate with a firm price.
Does replacing both furnace and AC at the same time cost less?
Usually yes. Doing both as one project saves on labor, gives you matched equipment designed to work together, and typically comes with stronger warranty coverage than replacing each side years apart.
How much more does high-efficiency equipment cost in NJ?
High-efficiency equipment (95%+ AFUE furnaces, 16+ SEER2 air conditioners) typically adds 25–40% upfront versus standard efficiency. In NJ it often pays back through lower utility bills, and qualifying systems can get NJ Clean Energy rebates and federal tax credits. Compare your heating options →
How much does new ductwork add to a replacement in NJ?
Partial duct repairs in North Jersey run about $1,400–$3,000; a full duct replacement can add $4,000–$8,000+ depending on the home. Duct cleaning (a few hundred dollars) is the cheaper fix when ducts are dirty but structurally sound.
Should I repair my old furnace or replace it?
The rule of thumb: if the repair costs more than about a third of replacement and the furnace is 15+ years old, replacement usually wins. See our full furnace replacement cost guide in NJ for the complete repair-vs-replace math.
