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.

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 Bealeton
Bealeton heats with electricity first, so a furnace here is the minority. About one owner home in five in the Census place burns propane or natural gas, and propane leads nearly two to one, 188 homes to 102. Across all of ZIP 22712, which runs well past the service district, propane alone heats close to one owner home in four, usually from a tank on the lot.
Keeping the outdoor unit makes sense when it’s clearly younger than the furnace. In a propane house here that unit is often a heat pump, with the furnace stepping in only when the weather turns hard. Its indoor coil rests on the furnace, so the new one has to fit under it and move the air it was built for. If the outdoor unit’s label shows nearly the furnace’s year, price the pair too: $8,898 to $23,000 installed.
How old your furnace is depends on when your street was built. The Census counts about 495 Bealeton homes from the 1980s and 305 from the 1990s, the decade the County’s plan says the subdivisions took off, mostly on half-acre lots. A furnace original to one of those houses has outlived most of its kind. From 2000 to 2010 Bealeton grew from about 900 homes to about 1,650, much of it along Station Drive and the west end, and those builder furnaces are reaching the age when inducers, boards and igniters take turns failing.
To Fauquier County a fuel-burning furnace is never an ordinary repair. A new propane or gas furnace takes a trade permit even in the old one’s exact spot, and with no town government in Bealeton, the County’s office is the only one involved.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
When it’s time
In a dual fuel house the outdoor unit works most of the year and usually gets replaced first, while the furnace behind it runs only on the coldest nights. Low hours don’t stop the calendar: a 1990s furnace still has a 1990s heat exchanger.
A house from the 2000s often runs the furnace it was built with. Around twenty years, inducer motors and control boards start to go, one after another.
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.
Choosing who installs it
Questions to ask anybody who quotes you, us included.
Most furnaces ship set for natural gas and get converted to propane on site, and the new gas connection gets leak tested before the first fire. Ask whether the quote covers both, and whether your propane supplier wants a call first.
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.

Ndung and Oscar were great. Everything went smoothly, and after the install they made sure to show me everything I needed to know about the new unit.
Questions
Any house that burns propane should have a working one near the bedrooms, new furnace or old. Fauquier County’s fire and rescue department takes requests for smoke and carbon monoxide alarms through a form on its public education page.
About seven owner homes in ten here already heat with electricity, so it’s common; the ducts and the electrical panel decide. The HVAC replacement cost estimator prices a new furnace and a heat pump system for your house, side by side.
$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.
