A Rectortown furnace and AC pair: valley summers, propane winters and storm limbs.
Valley summers here aren’t mild. The nearest long-record station, Warrenton 3 SE, at about the village’s height, puts the average July high at 85 and sees close to three weeks of 90 degree days each summer. Heat waves go past that: the Weather Service estimated heat indices over 115 across northern Fauquier in July 2011. Up on the Blue Ridge, Mount Weather logs about a sixth fewer cooling degree days; Rectortown, at 514 feet, gets the valley’s summers.
The winter half burns propane. Natural gas heats only a handful of owner homes in the 20115 ZIP, so a furnace and AC pair here means a propane furnace with the air conditioner’s coil on top. The more common electric setup, a heat pump with an air handler, is its own job at $8,499 to $21,650.
In the village the ducts came last. The register’s survey dates nearly half of Rectortown’s historic properties to 1880 through 1910, with bungalows and a Foursquare from the early 1900s, all built for stoves and fireplaces. Where central air went in later, the trunk often runs through the cellar and the upstairs is fed through an attic or behind knee walls. Check those runs before sizing: a larger outdoor unit on the same tired ducts mostly gets louder.
Storms are the other thing the outdoor unit lives through. In July 2025 a thunderstorm blew a large tree down at Rectortown Road and Frogtown Road, under a mile out, and the June 2022 storm that hit the Delaplane and Marshall areas with gusts near 85 mph landed on either side of it. After a storm, check the outdoor unit before the cooling goes back on: limbs on top, crushed fins, a tipped pad, a loose disconnect box. Then call us and we’ll check it all; the $99 diagnostic visit says whether it’s a repair or the reason to replace the pair.
Rectortown houses, by the numbers

Rectortown
Rectortown’s own ZIP, 20140, is post office boxes only, so the Census Bureau maps no area for it. These are ZIP 20115 as a whole, the Marshall ZIP area that holds nearly nine in ten of the Rectortown Census place’s homes, Marshall included.

- 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.

$8,898 to $23,000 installed for a furnace and air conditioner replaced together, 2 to 5 ton, from the same price book as our estimator. Where you land depends on the size of the house, the efficiency you pick, and what the ductwork and venting need.

When replacing both makes sense in Rectortown.
The rooms under the dormers never cool
In a story-and-a-half bungalow the upstairs sits right under the roof, often standing-seam metal here. If those rooms run hot while the first floor is fine, have the duct runs up there measured first. A new pair on the same starved run leaves the same hot room.
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 Rectortown.
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 Rectortown.
Ask every company that quotes the job, us included.
Did they go down and look at the cellar ducts?
In an old village house the main duct often crosses a stone cellar or crawlspace, where a crushed or pulled-apart joint sends air into the dirt instead of the rooms. Ask whether whoever quoted went down there with a light.
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.
Already holding another company’s quote?
Our free second opinion looks at the system you were quoted on and tells you what it actually needs, with our price if you want it.
What our customers say.
I would highly recommend SwiftPro for an HVAC replacement. The sales process was straightforward and fair and the installation was done to my satisfaction in a timely and complete manner (and I’m pretty demanding). Great job!

Furnace and AC replacement questions from Rectortown.
A limb hit my outdoor unit. Is the whole system done?
Not necessarily. Bent fins or a dented cabinet are often a repair; a punctured coil or crushed refrigerant line is a bigger one, and on an older pair it can tip the math toward replacement.
Should the new air conditioner be bigger than the old one?
Usually not. The size comes from a load calculation on the house today, additions and all; an oversized AC in a house with thick old walls cools fast, shuts off and leaves the rooms clammy. The HVAC replacement estimator gives the range first.
How much does a new furnace and AC cost in Rectortown?
$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.
