How much does it cost to replace an HVAC system in 2026?

About $10,350 to $20,200 installed for a new central AC + gas furnace pair at standard efficiency, or roughly $7,750 to $16,000 for a single ducted heat pump that replaces both — assuming the ductwork is reusable. A 3-zone ductless mini-split runs about $9,050 to $17,100. Duct repair or replacement, a higher efficiency tier, and your state's labor market move it from there.

What does HVAC cost per ton?

Installed, central AC runs about $1,500–$2,900 per ton and heat pumps $1,800–$3,600 per ton at standard efficiency (a ton is 12,000 BTU/h of capacity). A typical 2,000 sq ft home needs 3.5–5 tons depending on climate, so equipment alone spans roughly $5,250 to $18,000 before ducts, removal, and permit.

Is a heat pump cheaper than a separate AC and furnace?

Usually, yes. On our standard 2,000 sq ft reference home, a ducted heat pump runs $7,750 to $16,000 versus $10,350 to $20,200 for a central AC + gas furnace pair, because you're buying one machine instead of two. The gap narrows if the heat pump forces a $1,300–$3,500 electrical panel upgrade — see our heat pump vs. furnace + AC comparison guide for the full breakdown.

What drives HVAC replacement cost the most?

System type and tonnage first (set by your square footage and climate), then efficiency tier (high adds about 18% to equipment, premium about 40%), then ductwork condition ($800–$2,500 to repair, $2,400–$6,400 to replace on 2,000 sq ft), then your state's labor market, which swings the identical job roughly ±30% around the national average.

HVAC Costs & Pricing

What HVAC replacement costs in 2026 by system type, size, and efficiency tier — with the sizing math shown.

Quick answer

A new HVAC system for a typical 2,000 sq ft home costs about $7,750 to $16,000 installed for a ducted heat pump (mid $11,350) or $10,350 to $20,200 for a central AC paired with a gas furnace (mid $14,550) in 2026. A 3-zone ductless mini-split covering the same home runs about $9,050 to $17,100 (mid $12,950). Tonnage — set by your square footage and climate — efficiency tier, and ductwork condition move the number from there.

What drives the price

Four things set an HVAC bid, in order of impact: which system you buy, how many tons it needs, the efficiency tier, and whether your existing ducts survive. A heat pump does both heating and cooling from one outdoor unit, so it's usually cheaper than a separate AC condenser and gas furnace — one machine instead of two. Tonnage comes from your home's square footage run through a climate-zone BTU factor (roughly 20–30 BTU per sq ft for cooling, depending on climate), then adjusted for insulation, age, ceiling height, windows, and sun exposure.

Efficiency tier multiplies the equipment cost: stepping from standard (SEER2 ~15.2) to high (~17) adds about 18%, and to premium (20+, variable-speed) about 40%. Ductwork is the line item bids most often leave out — repair and sealing runs $800–$2,500, while full replacement runs $1.20–$3.20 per square foot, about $2,400–$6,400 on a 2,000 sq ft home.

Cost by system type

The table below prices five system types on the same 2,000 sq ft, mixed-climate reference home at standard efficiency, with old-system removal and the permit included. A ducted heat pump is the cheapest way to get both heating and cooling; a ductless mini-split (priced here at 3 zones) skips ductwork entirely and is the default choice for homes without usable ducts; central-AC-only and furnace-only are single-system replacements that reuse the other half of an existing pair.

Your state's labor market moves every one of these up or down — the same standard-tier heat pump that runs about $11,350 nationally costs closer to $15,300 in California and near $10,200 across much of the South. See our HVAC replacement cost guide for the full line-item math, or compare every state side by side in the cost-by-state report.

What to know before you commit

Two extras change a bid more than any other line item. Pre-1980 homes on 100 A electrical service often need a $1,300–$3,500 panel upgrade before a heat pump can go in, and cold-winter climates may need a cold-climate heat pump (about 15% more equipment) or a dual-fuel setup that keeps a gas furnace as backup below a balance point. Neither shows up in a lowball quote.

The federal 25C tax credit that used to shave up to $2,000 off a qualifying heat pump expired December 31, 2025 — every number here is 2026 list price with no credit baked in. State and utility rebates still pay, so check what survives before you sign, then get three local quotes and compare the duct, permit, and removal lines, not just the bottom number.

Typical 2026 HVAC replacement cost by system type — 2,000 sq ft, standard efficiency, installed
System type	Typical installed range	What it includes
Ducted heat pump	$7,750–$16,000	One outdoor + indoor unit for heating and cooling, removal, permit
Central AC + gas furnace	$10,350–$20,200	Separate AC condenser and gas furnace, removal, permit
Ductless mini-split (3 zones)	$9,050–$17,100	Outdoor unit + 3 indoor heads, no ductwork, removal, permit
Central AC only	$6,550–$13,200	Cooling only, reusing the existing furnace and ducts
Gas furnace only	$4,350–$8,600	Heating only, reusing the existing AC and ducts
