Two building waves in Orlean’s farm country, and the furnace and AC pairs they left behind.
Around Orlean the houses came in two waves, out among the farms. The Census block group centered on the village counts 140 homes built in the 1970s and 169 in the 1990s, out of 576, every one a detached house. A 1990s house here is likely on its second furnace and air conditioner or about due, and a 1970s house has usually been through two sets, still on the ductwork it was framed with.
Only some of those houses have a furnace and an air conditioner. Electricity heats 306 of the block group’s 543 occupied homes, mostly by heat pump, a different job at $8,499 to $21,650 installed. The furnace and AC pair is the propane house’s setup, 95 homes here. There the cooling coil sits on top of the furnace, so when both halves are the same age, doing them together opens that closet once.
The cooling half works harder than people guess this far out. Warrenton 3 SE, the nearest station with thirty-year normals, averages close to 21 days a year at 90 degrees or hotter, and the July 2019 heat pushed heat index values past 110 across northern Fauquier. A house on open ground takes the afternoon sun full on. Size both halves from one load calculation: the 17 degree night Fauquier County sizes heat to, and the 90 degree afternoon.
Storms settle some of these replacements. On June 22, 2022, gusts estimated at 80 to 90 miles an hour reached Orlean, bringing down thousands of trees; at least three buildings collapsed under them. A limb across a condenser can flatten the coil or crack a refrigerant line. After a storm, switch the cooling off at the thermostat, look at the outdoor unit before it runs, and call us to check it all. On a unit near twenty, a crushed coil usually starts the replacement talk, with the furnace under it priced alongside.

- A few homes still burn heating oil. We don’t work on oil burners, but a switch to a heat pump or a gas or propane furnace is ours to price.
- Electric heat here usually means a heat pump with backup strips, which is priced as a heat pump system, not a furnace and AC.

When replacing both makes sense in Orlean.
A tree came down on the outdoor unit
On June 12, 2026, one blew down at Cabin Branch Road and Cliff Mills Road, about a mile from the village. If a limb hit yours, leave the cooling off until it’s checked. A bent cabinet is cosmetic; a crushed coil on an older pair is a replacement.
Your heat may not be a furnace
Where a lot of homes heat with electricity, the indoor half is often an air handler, and the like-for-like swap is a heat pump system, $8,499 to $21,650 installed.
The outdoor unit runs on R-22
The label on its side names the refrigerant. R-22 hasn’t been made or imported in the US since 2020, so a leak gets expensive. Replace it on your schedule, not in July.
Who signs off on a new system in Orlean.
Fauquier County
Fauquier County counts swapping an electric appliance for a similar one in the same spot as an ordinary repair that needs no permit. Moving an appliance to a new spot takes one. Source.
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 who replaces your furnace and AC in Orlean.
Ask every company that quotes the job, us included.
Did the load calculation cover both seasons?
The same ducts carry 17 degree heat and 90 degree cooling here. Ask which season set the size, and whether they counted the windows and insulation, not only the square footage.
Do they size it to the house, or copy the old label?
The old size is a guess somebody made years ago. Ask whether they measure the house and check the ductwork first. Too big short cycles; too small runs all afternoon in August.
Is the whole job in the written price?
Furnace, outdoor unit, matching coil, refrigerant lines, thermostat, permit and hauling the old one away. If it isn’t on the paper, ask.

What our customers say.
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.

Furnace and AC replacement questions from Orlean.
We lost power in a storm and now the AC won’t start. Is it finished?
Not necessarily. Check the breaker and the disconnect beside the outdoor unit first. A surge when power comes back can take out a capacitor or a control board, which is a repair. The diagnostic visit is $99, and the tech prices the fix before starting it.
Should the outdoor unit move when it’s replaced?
Sometimes. If it sits under a big tree, or where snow slides off the roof onto it, a pad a few feet over can be worth the longer refrigerant lines. The written price shows both options.
How much does a new furnace and AC cost in Orlean?
$8,898 to $23,000 installed for the pair, by size and efficiency. A furnace alone, keeping your AC, is $4,285 to $14,040. The HVAC replacement estimator gives your house its own number.
Do I have to replace both at the same time?
No. If the AC is young and only the furnace failed, replace the furnace. If they’re the same age, do both: a new outdoor unit needs a matched coil, and one built for the old refrigerant isn’t rated for the new one.
