Why doesn’t this calculator tell me what HVAC replacement costs?

Because we cannot source it honestly. We hold no data on quotes or finished jobs, and national ranges are quote surveys by lead-generation businesses. For a budget band before you have a quote, use the HVAC replacement cost calculator , which labels where each band comes from.

What does this tool do instead?

It takes the price from your written proposal and works out three things: the price per ton, the yearly running cost on your state’s EIA 2024 prices, and the total over 15 years. The last one decides which bid is really cheaper.

Is the cheapest HVAC quote the cheapest system?

Usually not. Running cost is 42% to 77% of lifetime cost by state, more than the purchase price in 44 of 51 jurisdictions. The calculator shows how much extra running cost a cheaper bid can carry before it stops being cheaper.

What is a reasonable HVAC cost per ton?

We do not publish one. Work it out for each bid and compare them with each other. A wide gap between two bids for the same tonnage is worth asking about; it usually means a difference in scope, not margin.

Is there a federal tax credit to subtract?

No. 26 U.S.C. § 25C and 26 U.S.C. § 25D both ended for property placed in service after December 31, 2025, under Public Law 119-21. We read the statute September 5, 2026. A 2026 proposal showing a federal credit line is quoting repealed law.

Are there still HVAC rebates?

Yes. Utility rebates and DOE-funded state programs survive, because they are appropriations, not tax code. We publish no amounts, since we cannot recheck them on a schedule. The HVAC rebate finder points you to the administrators.

Where does the running cost figure come from?

EIA’s 2020 home energy survey (RECS) regional averages for heating and cooling, priced at EIA 2024 state rates. It is an average home in your region. If your bills differ, the total moves but the ratio holds.

It is the NAHB service-life guideline for central ACs and heat pumps, from a 2006 phone survey that calls itself a general guide. It sets the window, not a prediction for your unit. Change it if you have a reason.

Does this include maintenance and repairs?

No, on purpose. We have no sourced figure for lifetime maintenance and repair costs, and a made-up one would make the result less honest. Treat the total as a floor.

No. The price is your own figure; the running cost is a public average for your state. HyreHVAC does not install, service or sell HVAC equipment and takes no contractor fee for what this page shows.

What will your HVAC system really cost?

Your quoted price plus 15 years of running cost, on your state’s prices. We never invent an installed price.

57% of 15-year cost is running cost, median state HyreHVAC calculation: EIA RECS 2020 regional heating and cooling at EIA 2024 state prices, gas heat at 95% AFUE plus electric cooling, over 15 years, against a $9,000 reference invoice used only for scale.

The short answer

More than the invoice. Over 15 years, running cost makes up 42% to 77% of the total, depending on your state, and more than half in 44 of 51 jurisdictions.

So the cheapest bid is often not the cheapest system. Enter the price from your written proposal to see its full cost. Remove any federal tax credit line first: §25C ended after 2025.

What this assumed

—

An estimate, never a quote. The price is yours; HyreHVAC holds no price data. Running cost is a regional average at your state’s prices, undiscounted, with no repairs or price rises, so read the total as a floor. No federal credit: §25C and §25D ended after December 31, 2025.

Why doesn’t this HVAC cost calculator show prices?

Because we have no honest price data, and neither do most sites that show one. Read this before you trust any HVAC cost figure.

In most states, more than half of an HVAC system’s cost comes after the invoice. Fifteen years of heating and cooling against a $9,000 reference invoice, used only for scale.HyreHVAC calculation. Running cost is EIA RECS 2020 regional heating and cooling use at EIA 2024 state prices, gas heat at 95% AFUE plus electric cooling, over the 15-year NAHB service-life guideline. Undiscounted.

HyreHVAC does not install, service or sell HVAC equipment, and holds no data on quotes, invoices or finished jobs. Nothing here is a price we observed. That is also why these tools can tell you to keep the system you have.

What published figures really are: national HVAC cost figures are surveys of quotes, gathered by lead-generation businesses from contractors who buy their leads. They are not audited records of finished jobs, and the publishers have a stake in the number. Treat them as a wide band with a conflict attached.

Why the band stays wide: what moves an HVAC price most is invisible to a national survey: the tonnage the house needs, whether the ducts can be reused, electrical panel capacity, line-set length, attic or crawlspace access, and your permit fees. Two identical units on one street can be different jobs.

What you have instead: the price on your written proposal. What you lack is the lifetime cost, which the calculator adds. Here, running cost is 42% to 77% of the 15-year total, by state. That is usually bigger than the gap between bids, so the cheapest bid is often not the cheapest system.

The $9,000 invoice only gives the chart a scale. It is not an estimate of your job. Enter your own quote in the calculator and the shares change.

Why is one HVAC bid cheaper than another?

Sometimes the company is efficient. Often, four lines are missing, and each one protects the running cost the calculator shows.

A load calculation
ACCA Manual J (ANSI/ACCA 2 Manual J - 2016) establishes the heating and cooling load of the dwelling. ACCA says codes require it; check locally. A system sized by rule of thumb short-cycles, dehumidifies poorly and misses its rated efficiency.
Duct check or repair
Duct leaks are the most common fault in DOE’s review, found in 90-100% of systems tested. Ducts are invisible on a proposal and costly to fix later, so they get left out.
Commissioning: charge and airflow verified
Refrigerant charge and airflow are set on install day and decide whether the unit meets its rating. A bid with no line for checking them is not planning to.
Permit and inspection
A permit costs money and time. It also dates the work and puts an inspector over it. A bid without one is cheaper for a reason you will care about when you sell.
A federal tax credit line
On a 2026 proposal, that is an error, not a saving. For a residential HVAC installation completed in 2026, the federal tax credit is $0. There is no section of the Internal Revenue Code that provides one. Remove it before comparing bids.

Also ask each bidder for the AHRI Reference Number of the proposed pairing. A rating on a quote is a claim; a reference number can be checked. See the HVAC quote comparison.

Can a 2026 HVAC quote include a federal tax credit?

No. A federal credit line is the most common factual error on HVAC proposals right now, and it always makes the purchase look better.

26 U.S.C. § 25C, the Energy Efficient Home Improvement Credit, ended for property placed in service after December 31, 2025, under Public Law 119-21 § 70505(a), enacted July 4, 2025. Subsection (i) now reads: “This section shall not apply with respect to any property placed in service after December 31, 2025.”

26 U.S.C. § 25D, the Residential Clean Energy Credit (30% of cost with no cap, the geothermal credit), ended the same way: “The credit allowed under this section shall not apply with respect to any expenditures made after December 31, 2025.” We read both September 5, 2026.

HyreHVAC analysis: on a heat pump that was a $2,000 error. On geothermal with no cap it is often five figures. If one bid shows the credit and another does not, strip it from both before comparing.

What survives: utility rebates and DOE-funded state programs, because they are appropriations, not tax code. They are run locally and we publish no amounts. The HVAC rebate finder points you to the administrators.

Not tax advice: HyreHVAC is not a tax adviser and takes no fee from any incentive program. The statute is quoted with the date we read it. Confirm at irs.gov before acting.
