Most people type "HVAC near me" at the worst possible moment — the house is 85 degrees, the kids are complaining, and comparison shopping is the last thing anyone wants to do. This is the compressed version, written so you can still hire a decent contractor even when you're in a hurry.
The short answer: a full AC-and-furnace replacement runs roughly $6,500 to $16,000 installed in 2026. Get three quotes on the same scope, insist on a Manual J load calculation, and make sure the contractor — not you — pulls the permit. Also worth knowing up front: the federal tax credit that a lot of sales pitches still reference expired at the end of 2025.
What it should cost
Here are the national installed price bands for 2026. "Installed" means the equipment, the labor, the permit fee, and haul-away of the old system — all in one number.

Two things routinely push a quote outside those ranges. New ductwork typically adds $2,100 to $4,000, and electrical panel upgrades or tight attic and crawlspace access can add hundreds to a few thousand more. Regional labor rates swing the totals more than brand choice does — a Bay Area quote and a Kansas City quote for the same equipment are not going to look alike.
A quote above the band isn't automatically inflated. But if it is, you deserve a written reason on the estimate, not a verbal explanation on the doorstep.
Why 2026 prices are higher than 2024
Two separate changes landed on top of each other, and homeowners are paying for both.
The refrigerant transition. Under the EPA's Technology Transitions rule, new residential HVAC systems can no longer use refrigerants with a global warming potential above 700. That took R-410A out of new equipment and shifted manufacturers to R-454B and R-32. Both are classified A2L, meaning they're mildly flammable, so the new equipment needs leak detection, revised charge limits, and updated service procedures. Manufacturing costs climbed an estimated 15 to 20 percent, and the price the homeowner pays is up roughly 8 to 10 percent.
The tax credit ended. The Section 25C Energy Efficient Home Improvement Credit — up to $2,000 back on a qualifying heat pump — was terminated by the One Big Beautiful Bill Act signed on July 4, 2025. It only applied to systems placed in service on or before December 31, 2025. A system installed in 2026 doesn't qualify, and it doesn't matter when it was ordered or paid for. If a contractor is still leaning on that credit to justify a higher-tier system, they're working from stale information — that alone is a reason to get a second opinion. State and utility rebates are a different program; many are still active, and worth 15 minutes of research on your utility's website before you sign anything.
Five checks before you sign

The most expensive mistake homeowners make is accepting a single bid. On identical scope, the spread between the highest and lowest quote is routinely several thousand dollars, and the high bid is almost never the better install — it's usually just the contractor with more overhead.
The second most expensive is skipping the load calculation. A Manual J sizes the equipment to your actual house — square footage, insulation R-values, window area and orientation, air leakage. Sizing the new system by matching whatever tonnage was there before just perpetuates whatever mistake the previous installer made. Oversized units short-cycle, cool the house unevenly, and never run long enough to pull humidity out of the air — which is why people with brand-new systems still complain that their house feels clammy.
Ask the contractor for their license number and check it yourself with your state licensing board — don't take their word for it. Ask for a certificate of insurance sent directly from the insurer's office. A photo of a certificate on the contractor's phone is worth roughly what the paper it's not printed on is worth.
Reading the quote
A quote you can actually compare against another quote has line items on it. At minimum: model numbers for the condenser, indoor coil, and furnace or air handler; labor; permit fee; disposal / haul-away; thermostat; refrigerant line set; and startup and commissioning. When all you have is one lump-sum number, you have no way to tell whether the more expensive quote is padding or is actually pricing a better system.
Red flags that are worth walking away over: pressure to sign the same day, a "discount that expires this afternoon," a refusal to pull the permit and a suggestion that you pull a homeowner permit instead, no written scope of work, and a quote produced without anyone physically looking in your attic, basement, or at your electrical panel.
Repair or replace?
The rough decision rule most technicians use: if the system is more than 12 to 15 years old, the repair estimate is more than one-third of the cost of a replacement, and it's the second failure inside two years, replacement usually wins. Below any of those thresholds, repair is normally the right call.
A failed compressor on an older R-410A system is the classic tipping point in 2026. R-410A is still legal to service, but production is winding down, so the refrigerant itself is getting steadily more expensive to top up. Sinking $2,500 into a repair on a 14-year-old unit that will need refrigerant again in two years, on a system that has to be replaced within the decade anyway, is rarely the smart trade.
Supplying your own equipment
Buying the equipment yourself and hiring an installer for labor only is legal in most states and can cut several thousand dollars off the total project cost. It also comes with real trade-offs that are worth understanding before you order anything.
Some manufacturers limit or void the parts warranty on equipment that wasn't installed by an authorized dealer. Some contractors won't touch owner-supplied equipment at all, because they can't control the specification. And you carry the risk if the equipment turns out to be wrong for the load — the installer will bolt in whatever you hand them.
If you go this route, do it in the right order: get the Manual J done first so you know what tonnage and configuration you actually need, confirm the installer will still warranty their labor, and read the manufacturer's registration terms before you buy.

Three quotes on identical scope, a Manual J that sizes the system to your house, an itemized estimate, and a permit pulled by the contractor. That's the entire defense. Everything else — brand debates, SEER2 point-scoring, financing pitches — matters less than whether the system is sized right and installed by someone whose license you actually verified.
Frequently asked questions
How much does a new HVAC system cost in 2026? A full AC-and-furnace replacement runs $6,500 to $16,000 installed. AC only is $3,500 to $10,000. A gas furnace only is $2,500 to $8,000. A ducted heat pump that replaces both is $4,500 to $14,000. These are national installed averages; regional labor rates move them.
Is there still a federal HVAC tax credit in 2026? No. The Section 25C credit expired for systems placed in service after December 31, 2025 under the One Big Beautiful Bill Act. State and utility rebate programs are separate and many are still running — check your utility's website and your state energy office.
Why did HVAC prices jump between 2024 and 2026? Two things. The EPA capped refrigerant global warming potential at 700 for new residential equipment, pushing manufacturers off R-410A and onto R-454B and R-32 with new leak-detection and safety hardware. And the federal tax credit that offset some of that cost expired at the end of 2025.
How long does an HVAC install take? A straight equipment swap is 4 to 8 hours. A full AC-plus-furnace change-out is one to two full days. Ductwork modifications add another day or two on top of that.
Do I need a permit for HVAC replacement? In most jurisdictions yes, and the contractor should be the one pulling it. Unpermitted HVAC work has a way of surfacing during a home sale inspection years later, and the fix is always more expensive than the original permit would have been.
How many contractor quotes should I get? Three, on identical scope and equipment tier. It's the single cheapest form of consumer protection available on a project this size.
Should I repair my old system or replace it? Weigh the repair cost against the system's age. Past 12 to 15 years old, with a repair over a third of replacement cost, replacement is usually the better financial call — especially on older R-410A systems where refrigerant itself is getting more expensive.
What is a Manual J load calculation, and do I really need one? Yes. Manual J is the ACCA-published procedure for sizing HVAC equipment based on your specific home — square footage, insulation, windows, orientation, and air leakage. Any contractor who sizes by "matching what's there" or by square footage alone is guessing.
The bottom line
Three quotes, a Manual J, an itemized scope, and a permit pulled by the contractor. That's the whole playbook. Prices are higher in 2026 for real reasons — the refrigerant switch and the expiration of the federal credit — but the fundamentals of hiring well haven't moved. A right-sized system installed by a licensed contractor you verified will outperform a slightly more efficient system installed badly, every time.
