Upperville furnaces burn propane, and the coldest night they’re sized for is 17 degrees.
Utility gas doesn’t show up in ZIP 20184 at all. The Census survey there is a small one, 67 owner homes with a wide margin, but it finds about two in three heating with electricity, the other third on propane, and none on a gas main. So a furnace replacement in Upperville means a propane furnace drawing from a tank on the lot. If the new one is larger than the old, or the line from the tank was sized tight to begin with, the supplier may want to look at the regulator, so give them our install date.
Purcellville’s co-op station, about 14 miles northeast at 510 feet, is the closest long weather record to the village’s 557. Across 1991 to 2020 its January nights averaged 24.5 at the low, about 115 nights a year got down to freezing, and five or so hit 10 or colder. For sizing, the County’s design criteria use a 17 degree winter night. We figure the heat loss of your rooms against that night, then choose the furnace.
Out on the farms the answer can change. The Mount Weather station on the Blue Ridge, under five miles north at 1,659 feet, piles up about 7 percent more heating degree days than Purcellville, and its January lows run two degrees colder. A house up the slope toward Ashby Gap or Sky Meadows needs more heat on the same night than one on Route 50, and its furnace gets sized for where it actually stands.
The village’s oldest houses came long before any furnace: the register survey dates sixteen of its main buildings to before 1830, and many carry brick or stone chimneys at the gable ends. Where a furnace vents into one of those, a high-efficiency replacement usually leaves the chimney and exhausts out a side wall in plastic pipe instead. Power is the other half. On May 20, 2026, downed poles and lines closed half a mile of Route 50 just west of the village, and a propane furnace’s igniter and blower stop when the electricity does.

When a new furnace makes sense in Upperville.
The furnace vents up a chimney built for wood fires
An unlined masonry flue made for a fireplace can be too big and too cold for a modern furnace’s exhaust, which then condenses inside and works at the mortar. Crumbling at the chimney top, or a damp patch on the wall beside it, is the tell. A replacement is the time to settle the venting.
The heat exchanger is cracked
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.
It’s fifteen or older and acting it
Fifteen to twenty years is a gas furnace’s usual run. Past that, parts get harder to find and each repair buys less time.
Who signs off on a new furnace in Upperville.
Fauquier County
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.
How to pick the best furnace replacement company in Upperville.
Questions to ask anybody who quotes you, us included.
Did they size it for the 17 degree night, or copy the old label?
Ask for your house’s heat loss figure in writing. In a house built in sections, a stone or log core with frame wings added later, the plate on the old furnace records what somebody guessed decades ago, not what the rooms need now.
Did they size it to your house?
Ask how they picked the size. Copying the old nameplate repeats whatever was guessed when the house was built.
Did they check the air conditioner you’re keeping?
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.
Will they tell you if it’s worth fixing?
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.

Furnace replacement questions from Upperville.
Who issues the furnace permit for an Upperville house?
That turns on the county line, not the mailing address. In the village and the rest of the Fauquier side, Community Development in Warrenton wants a trade permit for any propane furnace, even dropped into the old one’s spot. North of the line, Loudoun County requires a permit for a furnace swap too, though since October 2025 one with the same BTUs in the same place needs no drawings.
Should a heat pump do most of the heating, with the propane furnace as backup?
Price it both ways. Most 20184 homes already heat with electricity, which out here usually means a heat pump. Paired with a propane furnace, the heat pump handles the mild days and the furnace takes over on the coldest nights. The HVAC replacement cost estimator gives a range for each.
How much does a new furnace cost in Upperville?
$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.
Should I repair it or replace it?
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.
