Where you land in a range is mostly the distance from the outdoor unit to the room, the kind of head and the room left in the electrical panel.
The second zone costs the most because it often needs a bigger outdoor unit. Our mini split cost guide explains.
What’s different in Remington
Remington’s oldest houses were built before anybody ran ductwork. ZIP 22734 has 287 homes from before 1940, close to one in five, and Fauquier County’s plan counts 75 buildings in town worth a place on the historic registers, Queen Anne and Victorian houses among them. Plaster walls, narrow stairs and no spare attic often leave a duct system nowhere good to go, while ductless asks only for a small hole per head and a covered line set down the outside wall.
Most of those houses are rented: of the occupied pre-1940 homes in the ZIP, the Census counts 229 rented and 50 owned. If you rent, the landlord decides. If you own one and rent it out, a head adds cooling and heat to a room without tearing into the finishes a tenant lives with, and the work happens on walls you pick.
An I-plan house has no interior rooms: front to back it’s a single room, so each bedroom touches the outside, and a head can hang on that wall with its lines dropping straight down outdoors. Two heads sharing one outdoor unit price as two zones, $11,000 to $15,000. Across the ZIP about four homes in five are detached, and a sunroom, a garage apartment or a rear addition is where a single head usually lands.
Placement is the Remington question. Fauquier County’s plan blames the Rappahannock and Tinpot Run for flooding part of downtown now and then, on old lakebed soils that hold water. The condenser for a ductless system can be wall-mounted on brackets or raised on legs, clear of standing water and of drifts; after January 2016’s blizzard, snow stood 25 inches deep at Warrenton 3 SE.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIP 22734 as a whole, the Town included: its own homes are too few for steady Census figures. About one home in fourteen in this ZIP is in Culpeper County.
When it’s the right call
If an old house still cools with window units, each one blocks a window, rattles all night and comes out again in the fall. One multi-zone system can take over from all of them, and covering three rooms is $12,500 to $18,000 installed.
The bonus room, the sunroom, the bedroom over the garage. We check for a closed damper or a crushed duct first; sometimes that’s all it is.
An addition, a finished attic, a garage turned into a room. Stretching the ducts into it usually starves the rooms already on them.
Paperwork, 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 worth asking anybody who quotes you, us included.
On a low downtown lot, ask whether it goes on a bracket or a stand, how far up, and which way its refrigerant lines and condensate drain will run. Near Tinpot Run, a condenser sitting on the dirt is the one a flood finds.
If the room’s trouble is a closed damper or a crushed duct, a mini split is an expensive fix for a cheap problem. Ask what they checked first.
Ask whether it covers the line set run, the new circuit and putting the walls back, or only the equipment.

Swiftpro did an excellent job installing a minisplit unit for us in our sunroom. They were super professional.
The system we put in first
Built to take a beating. Put in by our crew.
Heat lamps, snow and rain on one outdoor unit: that’s Trane’s own film. We’re a Trane Comfort Specialist, on Trane’s own dealer locator, and when you pick a Trane, our crew puts it in.
Films: Trane’s own.
Questions
Through most of the winter, yes. Cold-climate models list their heating output at 5 degrees; the County’s design night is 17, though the nearest NOAA station logged 3 degrees in January 2014. In a house that old, with old windows, keep a backup for the deepest cold. Four heads on one system come to $16,000 to $21,000, and the estimator quiz prices your own mix.
Installed, one zone is $7,000 to $10,000, two zones $11,000 to $15,000 and three zones $12,500 to $18,000, up to $23,000 to $30,000 for six. The HVAC price estimator gives your number.
Both. A ductless system is a heat pump, and cold-climate models keep heating well below freezing, which covers a Northern Virginia winter.
