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 Centreville
Only about one Centreville owner home in a hundred was built before 1960, so the classic case for ductless, an old house heated by radiators with no ducts at all, barely exists here. Nearly every house has a gas furnace or a heat pump pushing air through ductwork. What a mini split solves in Centreville is the room that ductwork was never laid out for, or the floor one thermostat can’t keep comfortable.
That floor is most often the top one in a townhouse, close to half of Centreville’s homes. One system on the lowest level feeds three floors; the bedrooms at the top get the longest runs and the attic’s heat, and the thermostat sits two floors below them. A single head in the main bedroom gives that floor a setting of its own and leaves the rest of the system alone.
The single-family houses, about three in ten, are where you find the rooms added later: a sunroom off the kitchen, a bedroom built over the garage, a screened porch closed in. A room like that has two or three outside walls and sits at the far end of the ductwork or off it entirely, which is why a head sized for its glass and walls tends to beat one more duct run.
Condo and apartment buildings hold about one Centreville home in seven. There the outdoor unit needs a spot the association approves, and some buildings have none to give, so ask before pricing one. It runs on electricity, billed by Dominion or NOVEC depending on where in Centreville the house sits.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
When it’s the right call
A walkout level finished after the house was built often runs on a couple of registers off a trunk sized for an empty basement. A head down there heats it on its own setting in January and cools it in July, without asking more of a system already feeding three floors.
In a three-level townhouse the heat rises to the bedrooms, and one thermostat can’t please two floors. A head upstairs gives that floor its own setting.
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.

Choosing who installs it
Questions worth asking anybody who quotes you, us included.
In a townhouse row there isn’t much wall to work with, and the line set may have to climb the back of the house to reach a top-floor head. Ask to see the route and the outdoor unit’s spot before you sign, and check both against your community’s rules.
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 was responsive and easy to work with for the mini split installation. The technicians Moises and Oscar were great! Would recommend!
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
For a hot top floor, one head in the main bedroom may be enough. If the other bedrooms up there run just as warm, one outdoor unit can carry two or three heads, each its own zone with its own setting. Zone prices are in the table above.
It can be, if the main system is otherwise sound. A bit over a quarter of occupied Centreville homes are rented, and one head upstairs gives the tenants a setting of their own without replacing the system that runs the rest. Clear the outdoor unit’s spot with the association first.
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.
