What it costs
The same price book our estimator runs on, for a central air conditioner on its own, keeping the furnace you have. A single-stage unit on a small house sits near the bottom; a variable-speed one on a big house, near the top.

Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
The HVAC replacement cost estimator narrows it to your house. Then a tech measures, and you get the installed price in writing before anything is ordered.
With Comfort+ membership at $199 a year, the diagnostic visit is included, and half of each repair bill is banked toward replacing that system, up to $1,500.
What’s different in Midland
What heats the house decides which job you have. Of the 1,066 owner homes in ZIP 22728, the Census counts 622 heating with electricity, 354 with propane and 12 on a utility gas line. In the electric houses the yard unit is usually a heat pump, replaced for $8,499 to $21,650 installed. The Midland air conditioner replaced by itself sits in one of the 354 propane houses: a tank-gas furnace, a cooling coil on top, a condenser outside. If that furnace has winters left, it stays.
The railroad laid out the village in 1873, and its I-houses went without cooling until ducts came decades later. Beyond the old depot streets the housing is mostly younger: the ZIP counts 406 homes from the 1980s and 1990s and 315 from 2000 on. The builder’s condenser on a Midland house from the first years after 2000 has had close to twenty summers, and a unit that age often still runs on R-22, out of production since 2020.
NOAA’s normals for Warrenton 3 SE, six miles north-northwest at about 500 feet to the village’s 327, put the July high near 85 with about 21 days a year at 90 or hotter, and on June 29, 2012, the Weather Service logged heat indices of 110 to 114 across Southern Fauquier. Size the new unit for afternoons like that on your own house, not on the old label: an open Midland lot with no shade on the roof changes the number.
Then pick the spot. The weather station at Warrenton-Fauquier Airport, inside the Midland service district, measured a 74 mph gust on August 13, 2021. Marsh Run carries floodplain on the village’s southwest side, and the August 10, 2022 flash flood closed VA-610 in Midland. Set the new condenser on a level pad or stand above any water you’ve seen stand, clear of the big limbs.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIP 22728 as a whole: every Midland address, the village included. The Census place for the village alone has too few homes for steady figures.
When it’s time
On open Midland ground a limb through the fan or a gust that rolls the cabinet can end an outdoor unit in one afternoon. Read the date on the propane furnace before deciding. If it’s years younger, swapping only the outdoor half and its coil is the sensible call. Same year as the wrecked unit? Price the pair too, $8,898 to $23,000 installed.
An air conditioner put in before 2010 most likely holds R-22, which hasn’t been made since 2020. A leak on one of those usually ends the repair road.
It’s the pump at the heart of the outdoor unit and its costliest part. Out of warranty on an older unit, the repair can come close to half the price of a new AC, the point where Goodman says replacing may be the better money.
Permits, locally
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.

Choosing who installs it
Questions to ask anybody who quotes you, us included.
The coil has to fit that furnace’s cabinet and the air its blower moves. A 1990s Midland furnace often has a single-speed blower, which caps what a two-stage or variable-speed condenser can deliver. Ask for the furnace model on the quote.
Ask how they picked the size. Copying the old nameplate repeats whatever was guessed when the house was built.
The outdoor unit and the coil on the furnace are rated as a pair. Ask whether the quote replaces both, and what happens to the line set.
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.

Questions
Yes, and on that side of the village it’s worth pricing. A raised stand keeps the coil, fan motor and wiring above standing water. A new location is Fauquier County permit work, so the quote shows the same-spot price and the raised one side by side.
Probably not. A unit that heats as well as cools is a heat pump, the more common setup in 22728, and replacing one is $8,499 to $21,650 installed. This page is for a condenser that only cools, beside a propane furnace. A $99 diagnostic visit tells you which you have and prices any repair.
$5,942 to $14,450 installed for a central air conditioner on its own, keeping the furnace you have; size and efficiency set where yours lands. An AC and furnace together run $8,898 to $23,000. The HVAC replacement cost estimator gives your house its own number.
It’s worth pricing. A heat pump cools exactly like an AC and also heats on mild days, so with your gas furnace it becomes dual fuel. A heat pump system runs $8,499 to $21,650 installed, and we’ll price it both ways.
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 AC is worth fixing, you’ll hear that first.
