By the HVAC Service Call editorial team · Ranges reconciled from Trane and Fuse Service 2026 pricing data
Most full HVAC replacements cost $7,500–$15,500 installed in 2026, with the wider range running $5,000–$28,000 by system type and efficiency. A furnace or AC swap sits low; a high-efficiency heat pump or ductless system sits high — the exact price is a quote from the contractor after they size your home.

New system cost by type
Equipment and installation, pre-tax. Ranges reconciled from Trane's and Fuse Service's 2026 published figures; your quote depends on size, efficiency, and your home.
| System | Typical installed cost |
|---|---|
| AC + gas furnace (split) | $8,500–$14,000 |
| Air conditioner only | $6,958–$13,418 |
| Gas furnace only | $3,800–$12,000 |
| Heat pump (ducted) | $9,500–$17,000 |
| Ductless mini split | $10,000–$18,500 |
| Dual-fuel (heat pump + furnace) | $12,000–$19,000 |
Costs by individual system live on AC installation, furnace replacement, heat pump installation, and mini split installation.
What's inside the quote
Homeowners get one lump number. Here's what it's made of — and why two quotes for the same house differ.
| Line item | Share of the total |
|---|---|
| Equipment (unit + matched coil / air handler) | 40–55% of total |
| Labor | $2,000–$6,000 (30–50%) |
| Remove & dispose of the old system | included |
| Permits & inspection | usually included |
| Add-ons (thermostat, line set, pad, electrical) | varies |
The add-ons are where identical-looking quotes split apart — a new line set, an electrical upgrade, or duct changes can swing a bid by thousands. Get it itemised. The one-time diagnostic fee is separate and explained on service-call cost.
Seven things that change the number
Two quotes for the same house differ because of these seven variables — the biggest being system type, efficiency, and the state of your ductwork.
| Factor | What it does |
|---|---|
| System type | A ductless or dual-fuel system costs more than a standard AC-and-furnace split |
| Home size & tonnage | A correct load calculation sets the capacity you actually need |
| Efficiency | A higher SEER2, HSPF2, or AFUE rating costs more up front and less to run |
| Ductwork condition | Repairing or replacing ducts adds $2,000–$7,500 |
| Install complexity | Attic units, tight closets, or a crane lift add labour |
| Region & season | Metro labour rates and peak-season demand move the total |
| Permits & code upgrades | A new disconnect or code-required safety work adds cost |
An oversized system costs more up front and runs worse — it short-cycles, never pulls humidity from the air, and wears its parts faster. An undersized one never keeps up on the hottest or coldest days. Insist on a Manual J load calculation instead of matching the old unit's tonnage — the old one may have been wrong too. The AC sizing guide shows how the math works.
Rebates, tax credits & financing
Qualifying high-efficiency equipment can cut what you actually pay — but the federal picture changed at the end of 2025, so the live money is now state, utility, and manufacturer rebates plus financing.
30% up to $2,000 heat-pump credit — expired Dec 31, 2025 (per ENERGY STAR / IRS). No longer applies.
Many states, utilities, and manufacturers still run heat-pump and high-efficiency rebates; these vary by ZIP code and change often, so check what's active at quote time. Financing is widely available to spread a five-figure system over years. Heat pumps carry the most incentives — the detail is on heat pump installation.
Repair or replace?
Replace when a repair tops a third of a new system's price, when the unit is past 15 years, or when a major part fails — a cracked heat exchanger or a dead compressor is usually an automatic replace.
Multiply the unit's age by the repair cost; over $5,000 leans toward replacement. And a like-for-like swap is usually a one-day job — four to eight hours — while adding ductwork or converting fuel types runs two to three days.

Questions homeowners ask first
How much does a new HVAC system cost in 2026?
Most full HVAC replacements run $7,500–$15,500 installed, with the wider range landing between $5,000 and $28,000 depending on system type, efficiency, and your home. A straightforward furnace or AC swap sits at the low end; a high-efficiency heat pump or ductless system with duct work sits at the high end. The exact number is a quote from the contractor after they size your home.
Is it worth replacing my HVAC system before it breaks?
Often yes, if the system is past 15 years. Replacing on your schedule lets you shop quotes, catch off-season pricing, and avoid a mid-emergency decision — a failure in a heat wave or cold snap forces a rushed, more expensive replacement. Under 10 years and running fine, keep maintaining it.
Does homeowners insurance cover a new HVAC system?
Rarely. Standard homeowners insurance covers sudden damage from a covered peril — a fire or a fallen tree — not wear-and-tear failure or age. A home warranty may contribute toward replacement, subject to caps, a service fee, and maintenance requirements. Read the actual coverage before counting on it.
Should I replace the AC and furnace at the same time?
If both are near the end of their life, replacing them together usually costs less than two separate visits and guarantees the indoor and outdoor units are matched for efficiency. A mismatched pairing — a new AC on an old furnace blower — can lose the efficiency you paid for.
How do I know if an installation quote is fair?
Get it itemized in writing — equipment, labor, permits, and add-ons broken out — and get a second opinion on anything over a few thousand dollars. A fair quote includes a load calculation, removal of the old system, permits, and a written warranty. One call routes you to a licensed local contractor for that estimate.
How long does a new HVAC system last?
Air conditioners last about 15 years; furnaces and heat pumps 15–20, per manufacturer estimates. Regular maintenance and a correctly sized, well-installed system reach the top of that band; skipped maintenance and poor sizing cut it short.
