How much does a new furnace cost in Virginia?

There is no single Virginia price for a new furnace, and no state agency publishes one. The clearest public reference is a manufacturer's own guide: When we checked on October 26, 2026, Trane's 2026 national guide put its installed gas furnaces at $5,093 to $6,386 for models rated up to 80% AFUE and $6,630 to $8,390 for models rated up to 96% AFUE.^[1] Treat that as a starting point. Your real number comes from written quotes after a contractor has looked at your house.

What the published ranges cover

Trane prices three product lines at each efficiency level. On October 26, 2026, its guide listed:

• Up to 80% AFUE: $5,093 to $5,481 for its single-stage Choice line, $5,530 to $5,934 for the multi-stage Priority line and $6,000 to $6,386 for the Premier line^[1]
• Up to 96% AFUE: $6,630 to $6,946 for Choice, $6,851 to $7,412 for Priority and $7,569 to $8,390 for Premier^[1]

Read the fine print before comparing those to a quote. Trane says its furnace price ranges include product and labor costs and the basic accessories and services its dealers provide, before tax,^[1] but they do not include accessories such as a thermostat,^[1] and its footnote adds that the estimates do not include required accessories or installation requirements.^[1] The ranges are national averages, and Trane says costs vary with geography, climate, home size, system size, home configuration, existing ductwork and selected features.^[1] Other brands price differently, and an electric or oil furnace is a different job again.

What drives the price up or down

Efficiency. AFUE is the share of fuel that becomes heat: a furnace with an AFUE rating of 80 converts 80% of the fuel it burns into usable heat.^[5] Higher-AFUE models cost more and save fuel every winter. ENERGY STAR puts Virginia in its "U.S. South" region, where a gas furnace needs a rating of 95% AFUE or greater to be certified.^[4] It says those furnaces carry a "U.S. South" label and are up to 16 percent more efficient than standard models.^[3] Its view is that even though these products can be more expensive to purchase up front, the cost difference will be paid back over time through lower energy bills.^[3] How fast that happens depends on your house and your fuel price.

Staging. Trane explains the options: single-stage units are either on at 100% or off, two-stage units have a high and a low speed, variable-speed units can run from 30% to 100% of capacity, and modulating gas valves operate between 40% and 100%.^[1] More stages mean steadier temperatures and a higher price. Trane gives the extreme case: a modulating condensing furnace will cost more than a comparably sized single-stage unit with a lower AFUE rating.^[1]

Size. A larger-capacity furnace costs more, which is one more reason to insist on a heating-load calculation rather than matching the old unit. An oversized furnace costs more to buy and can short cycle once it is in.

Installation changes. This is where quotes for the same furnace part ways. Bryant notes that the final price may include the furnace, labor, permits, venting, ductwork, electrical work, gas-line modifications and other installation requirements,^[2] and that installation requirements can vary significantly between standard and condensing equipment.^[2] Ask each contractor what venting, drain or duct work the model you choose needs, and to price it separately. A furnace in a tight attic or crawl space usually takes longer than one in an open basement.

The permit. Fees are set by each locality. Spotsylvania County's mechanical permit packet, updated in August 2025, lists an HVAC or furnace replacement at $147.00, which is a $100 trade fee plus a 2% building surcharge and a $45 processing fee.^[6] Spotsylvania adds a 2.70% convenience fee when the permit is paid by debit or credit card.^[6] Your county or city will charge its own amount; ask whether it is in the quote.

Fuel. Virginia Cooperative Extension's advice is to check with your local utility before replacing an existing system,^[5] and to compare the fuel cost per amount of heat produced, not the price of a gallon, a therm or a kilowatt-hour.^[5] A switch from oil or propane to natural gas, or from a furnace to a heat pump, changes both the installed price and the running cost.

Tax credits and rebates

The federal credit many older articles mention has ended. The IRS says the Energy Efficient Home Improvement Credit covered improvements made through December 31, 2025.^[7]

Virginia's federally funded Home Energy Rebates come as two programs, and the appliance one will not help with a gas furnace. Virginia Energy states: "Under current DOE program guidance, High Efficiency Appliance Rebates cannot be used to help pay for replacement of a non-electric appliance."^[8] The other program, HOMES, will support energy retrofit projects resulting in at least 20% modeled savings,^[8] and Virginia Energy is in the process of establishing detailed eligibility criteria for this program.^[8] Virginia Energy says it cannot give a date for when the Home Energy Rebates will be available,^[8] and warns households against contractors who promise rebate eligibility before the programs launch.^[8] Utility programs change from year to year, so ask your gas and electric companies what they offer before you sign.

What to ask for in a written quote

ENERGY STAR advises getting written, itemized estimates, and to be sure to compare cost, energy efficiency and warranties.^[9] It also cautions that the lowest price may not be the best deal if it is not the most efficient, because your energy costs will be higher.^[9]

A quote you can compare line by line names:

• the furnace brand, model number, AFUE and capacity, and how the contractor sized it;
• any new venting, condensate drain, duct, gas line or electrical work, priced separately;
• the permit, the inspection and removal of the old furnace;
• the thermostat, if one is included;
• the manufacturer's parts warranty, any labor warranty, and who registers the equipment.

Virginia's Board for Contractors also requires the written contract to state the amounts and schedule for progress payments, including a specific statement on the amount of the down payment.^[10] Be wary of a large deposit before any equipment is ordered.

When to call a licensed pro

A furnace replacement is licensed work from start to finish: gas or oil piping, wiring, venting and combustion testing. Under Virginia law, no individual may work as a tradesman without a licence, and the Code's definition of a tradesman includes anyone doing heating, ventilation and air conditioning work for the public for pay.^[11][12] Check each business's licence with DPOR before comparing its price, as set out in how to check if a contractor is licensed in Virginia. A quote from an unlicensed installer is not a cheaper version of the same job.

Get at least two or three quotes when the old furnace is near the end of its life, so you are not pricing a replacement in an emergency.
