What it costs
The same price book our estimator runs on, for a gas furnace on its own, 2 to 5 tons, keeping the air conditioner you have. A single-stage furnace in a small house sits near the bottom; a modulating one in a big house, near the top.

Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
The HVAC replacement cost estimator narrows it to your house. Then a tech measures, and you get the installed price in writing, at no charge, before anything is ordered.
Natural gas or propane, in a house, a townhouse or a condo, we replace them all. Oil furnaces we don’t.
What’s different in Remington
Heat pumps warm most of Remington, which makes a furnace the exception here, and nearly always a propane one. Of the 858 owner homes in ZIP 22734, the Census counts 92 heating with bottled or tank gas and just 10 piped into a natural gas line. A new furnace ships ready for natural gas, so it’s converted to propane right there in the basement or closet, and the joint between the tank’s line and the furnace is pressure tested before the burners ever light.
Heating is the long season here. The closest NOAA climate normals come from Warrenton 3 SE, ten miles north-northeast and a bit higher up, and they put heating at about 4,685 degree days a year against 1,018 for cooling, better than four to one. Fauquier County’s code tables call for designing to 17 degrees in winter, the night a furnace is sized to carry, and real winters dip under it: that station read 3 degrees on January 7, 2014.
Where the furnace lives depends on the house. Downtown’s Queen Anne, Victorian and I-plan houses went up long before forced air was common, so the furnace in such a house tends to sit in a cellar or a closet, on ductwork added later, and its replacement has to come down the same tight stairs. In a newer house the propane furnace may be the backup half of a dual fuel system, firing only in hard cold. Few run hours don’t make it young: a 2005 furnace has a twenty-year-old heat exchanger.
Downtown also floods. Fauquier County’s plan names the Rappahannock and Tinpot Run as the reason part of downtown goes under at times, and at the river gauge in Remington the Weather Service expects parts of downtown near the railroad tracks to flood at 25 feet. In June 2018 the river crested at 23.1 feet, and NOAA’s storm log records water in a couple of homes. A cellar furnace that took water is a safety question before it’s a comfort one.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIP 22734 as a whole, the Town included: its own homes are too few for steady Census figures. About one home in fourteen in this ZIP is in Culpeper County.
When it’s time
Don’t relight it. Any gas valve that went under has to be swapped, and so does a soaked control board; drying them out doesn’t make them safe. If most of it was submerged, a new one set on a platform off the floor is the safer answer.
We replace propane furnaces as well as natural gas ones. The new furnace is set up for propane before it’s lit, and the quote is written for your house.
It’s the wall that keeps the burner’s exhaust out of the air the furnace blows through the house. Nobody patches one; a crack ends the repair conversation.
Permits, locally
Fauquier County wants a permit for any fuel-fired appliance, so a gas or propane furnace replacement is permit work even in the same spot. Trade permits need no plans, and usually no zoning approval. Source.
Our Virginia Class A contractor license, 2705192276, is on the side of the van.
Choosing who installs it
Questions to ask anybody who quotes you, us included.
A condensing furnace makes water as it burns and its exhaust leaves by a PVC pipe in the wall. In an old downtown cellar with no floor drain, that means a small condensate pump and a line to somewhere the water can go. Ask for both in writing.
Ask how they picked the size. Copying the old nameplate repeats whatever was guessed when the house was built.
A new furnace has to work with the coil and the outdoor unit already there. Ask whether they looked at both before quoting a furnace on its own.
A good company puts the repair price next to the replacement range and lets you choose. Already holding somebody’s big number? Take the free second opinion first.

We used Swifpro for a new hvac install and a plumbing repair. We felt the pricing for the hvac install was fair and offered a better product than their competitors. The techs were professional and timely.
Questions
The County. Fauquier treats every appliance that burns fuel as needing a trade permit, even a propane furnace set in the old one’s footprint, and its Community Development office in Warrenton issues those the day you apply. The Town of Remington keeps its own zoning, which a trade permit typically doesn’t involve. For a ballpark before anyone visits, try the estimator quiz.
$4,285 to $14,040 installed for a gas furnace on its own, keeping the air conditioner you have; size and efficiency set where yours lands. A furnace and air conditioner together run $8,898 to $23,000. The HVAC replacement cost estimator gives your house its own number.
Fix the small parts on almost any furnace. Past fifteen years, with a repair over a third of the price of a new one, replacing usually wins. Not sure which you’re looking at? The diagnostic visit is $99, and the tech prices the repair before starting it.
Ready when you are
Call, or send the form at the top. A tech measures the house and puts the installed price in writing before anything is ordered, and if the old furnace is worth fixing, you’ll hear that first.
