The lower level got finished, the ducts didn’t
A lower level finished years after the house went up often got one register tapped off the nearest trunk, or none. If it’s chilly all winter and stuffy all summer, it’s a room for its own head.
One room on its own ductless mini split runs $7,000 to $10,000 installed in Burke. Inside Burke Centre, the Conservancy signs off before it goes up.

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 Burke
Only about 2 in 100 Burke owner-occupied homes were built before 1960, so a house with no ductwork at all is rare here. The typical one went up in 1979, with ducts to every room it had then. Where a mini split earns its place in Burke is the space added since: a sunroom off the back, a room over the garage, a basement finished later, a garage turned into an office. The duct layout was drawn before any of those rooms existed.
Inside Burke Centre, every ductless system needs the Conservancy’s approval before it goes up. Its Architectural Standards put the outdoor condenser on the rear wall of the house with its base no more than a foot off the ground, and the refrigerant lines in a PVC or aluminum cover colored to match the siding or trim, run along the corners and edges of the house. So we plan the head inside around where that rule puts the condenser outside.
A window unit isn’t the easy way out in Burke Centre either. The Conservancy considers a window or wall air conditioner only when the owner brings an independent certification of why the existing system can’t do the job, and then normally on the side or back of the house, coming out once it’s no longer needed. A mini split needs an application too, but not that certificate.
Burke Centre’s condo buildings, about 1 in 8 of its owner homes, add one more layer: walls are shared, and a cluster can carry supplemental standards of its own. Outside Burke Centre, where most owner homes are single-family and a little over half burn gas, the furnace keeps heating the house and the head looks after the one room it can’t reach.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and the room a ductless head usually ends up in.
| Place | Median home built | Most homes are | Heated with | Where ductless usually fits |
|---|---|---|---|---|
| Burke | 1979 | single-family houses, about 6 in 10 | gas, about 6 in 10 | Additions, sunrooms and upstairs rooms the old ducts barely reach. |
| Burke Centre | 1982 | townhouses, about 5 in 10 | electricity, about 7 in 10 | Townhouses: the top floor, where the HOA allows the outdoor unit. |
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 lower level finished years after the house went up often got one register tapped off the nearest trunk, or none. If it’s chilly all winter and stuffy all summer, it’s a room for its own head.
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.
Plenty of older houses got central air added years after they were built, and the rooms at the end of the duct run are the ones that stay warm.

Choosing who installs it
Questions worth asking anybody who quotes you, us included.
In Burke Centre the condenser’s spot is set by the Conservancy: the back wall, low to the ground. A quote that starts with the head and leaves the outside for later can end with a longer line set than the price assumed.
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.

Questions
Usually. The condenser goes low on the rear wall, as the Conservancy requires, and the refrigerant lines climb the back of the house in their cover to a head up top, or run through a closet or wall to reach a front room. A longer run moves you toward the top of the range.
Two rooms on one outdoor unit run $11,000 to $15,000 installed, and three run $12,500 to $18,000. In Burke Centre that’s still one condenser on the rear wall for the Conservancy to review, not two.
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.
