A propane or gas furnace swap is permit work in all three counties.
Propane heats the largest share of ZIP 20106: about four owner homes in ten, against a bit over a third on electricity, about one in eight on oil and about two in a hundred on utility gas. A new furnace here is usually a propane one, which means it has to be set up for that fuel, and its gas connection leak tested, before it lights.
In ZIP 20106 the median owner home is a 1993 build. A furnace original to a house from 1980 through 1999, about a third of the ZIP, has been through three decades of winters. The heat exchanger decides it: a crack there can’t be repaired. A diagnostic visit is $99, and the tech prices the replacement beside any repair, so you see both numbers before you choose.
Swapping a gas or propane furnace is permit work on all three sides of the ZIP, because the state building code’s exemption stops at appliances that burn gas or oil. Rappahannock County’s Building Office, at 311 North Gay Street in Washington, takes the application on that side. Culpeper County’s Building Department, at 302 North Main Street in Culpeper, takes it online or in person. Fauquier County asks for one on any fuel-fired appliance, even in the same spot.
About one owner home in eight heats with oil. We don’t work on oil burners, so a house on oil is a switch: a propane furnace, a furnace and AC pair at $8,898 to $23,000, or a heat pump system. The new equipment has to meet real cold, 4,836 heating degree days a year at the Boston station and 3 degrees at Sperryville on January 27, 30 and 31 of 2026. The heating page lays out the options.

The Culpeper County side
ZIP 20106 as a whole: about half its homes are in Culpeper County, about four in ten in Rappahannock County, where the village is, and a few in Fauquier County.

What a new furnace costs in Amissville.
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.
- A gas furnace alone, keeping your air conditioner, installed$4,285 to $14,040
- A furnace and air conditioner together, installed$8,898 to $23,000
- Repair diagnostic visit, if it may be worth fixing$99
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.
When a new furnace makes sense in Amissville.
The furnace repairs keep adding up
A part is a fair fix on a furnace that’s otherwise sound. When repairs pile up on one from 1980 through 1999, you keep paying for equipment whose heat exchanger is the part that matters. With 4,836 heating degree days a year, finding that out on one of the nights near 10 degrees is the hard way.
You heat with propane
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.
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.
Who signs off on a new furnace in Amissville.
Rappahannock County
Virginia’s building code lets a home’s mechanical appliance be replaced without a permit only when it isn’t fueled by gas or oil, so in Rappahannock County a gas or propane furnace swap is permit work. Source.
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.
Outside the town limits, Fauquier County issues the permit. It wants one for any fuel-fired water heater, propane included, and for any heater being moved; an electric one swapped for a similar unit in the same spot counts as an ordinary repair. Trade permits go out over the counter the day the application comes in. Source.
How to pick the best furnace replacement company in Amissville.
Questions to ask anybody who quotes you, us included.
Do they price the fuel side as well as the furnace?
Ask whether the quote covers converting the furnace to propane and testing the new gas connection for leaks, and whether your propane supplier needs a heads-up. Get the whole job in writing before the old furnace comes out.
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 Amissville.
What if my Amissville house heats with oil?
Then the job is a switch. We don’t work on oil burners, but we do price a propane furnace, a furnace and AC pair, or a heat pump system in its place. About one owner home in eight in ZIP 20106 heats with oil, and the quiz on the heating page prices each option for your house.
Should I keep the air conditioner when the furnace goes?
Compare the two data plates. If the outdoor unit is clearly younger, the furnace can go in alone, and its new coil has to fit the unit you keep. If both date from the same year, they’ve aged together, and a furnace and AC pair at $8,898 to $23,000 installed is worth pricing beside the furnace alone.
How much does a new furnace cost in Amissville?
$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.
