One room stays warm after the rest of the house cools
A room over a garage or at the end of a duct run gets the least air, so the thermostat in the hall is satisfied while the far room isn’t. One head, sized to that room, cools it on its own.

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
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 Broad Run
Broad Run’s older houses, additions and garages: rooms the ducts never reached
About one in six of the ZIP’s owner homes predates 1960, just over half predate 1980, and the middle year is 1979. In houses that old, central air may have come long after the house, and some rooms sit at the far end of a duct run or off the ducts entirely. One head, with its own outdoor unit or a share of one, serves a single room and needs no ductwork.
The Broad Run and Little Georgetown Rural Historic District, almost 9,500 acres across Fauquier and Prince William, is on the state’s register. A garage, a workshop or an addition stands apart or sticks out past where the original ducts stop, and stretching a duct to it shortchanges the rooms already on it.
Heat is the hard part of July. Warrenton 3 SE puts a July afternoon near 85 and the night only near 66, and NWS estimated heat indices above 115 across Northern Fauquier on July 22, 2011. A room over a garage, or at the end of the ducts, gets the least air and the most sun. One head sized to that room fixes it. Three zones are $12,500 to $18,000.
The outdoor unit takes more thought than the head. A volunteer gauge about three miles south-southwest logged 14 inches of snow in a day in February 2014, FEMA maps a floodplain within a few hundred yards of the hamlet’s map point, and the 2017 tornadoes dropped trees on lines and homes. A wall bracket or raised stand puts the unit above snow and shallow water, clear of limbs.
By the numbers
Broad Run houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
The Fauquier County side
ZIP 20137 as a whole: every Broad Run address. About one home in six of them is on the Prince William County side.
- Median home built1979 Census
- Built before 1980about 5 in 10 Census
- Built since 2000about 2 in 10 Census
- Most homes aresingle-family houses, nearly all Census
- Heated withelectricity, about 5 in 10 Census
- Rentedhardly any Census
- Ducts in houses this age were often sized for the furnace, not for cooling, so upstairs rooms run warm in July.
- A single-family house usually has wall space for the outdoor unit behind the room, which keeps the line set short.
When it’s the right call
When a ductless mini split makes sense in Broad Run.
The far rooms never got the cooling
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.
One room is always wrong
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
How to pick the best mini split installer in Broad Run.
Questions worth asking anybody who quotes you, us included.
Did they size the head to the room, or to a rule of thumb?
A head for a sunroom with a lot of glass is not the same as one for a workshop with no insulation. Ask how the walls, glass and roof above the room were measured, and for the line route and drain on paper. The HVAC price estimator quiz gives your number.
Did they check the rest of the house first?
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.
Is the whole job in the price?
Ask whether it covers the line set run, the new circuit and putting the walls back, or only the equipment.

Questions
Ductless mini split questions from Broad Run.
Can the same head heat that room in a Broad Run winter?
Yes. The head that cools a room in July heats it in January. About 98 nights a year fall to freezing or below at Warrenton 3 SE, and a room that’s the cold spot of the house can get its own heat from a head, with the existing system carrying the rest.
How do I count zones in a house with no ducts?
One for each room that needs its own control, usually the main living areas and the bedrooms. Installed prices run by zone: four zones is $16,000 to $21,000, five is $19,000 to $25,000 and six is $23,000 to $30,000. A house with no ducts at all is done room by room, and one outdoor unit can serve several heads.
How much does a ductless mini split cost in Broad Run?
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.
Does a mini split heat, or only cool?
Both. A ductless system is a heat pump, and cold-climate models keep heating well below freezing, which covers a Northern Virginia winter.
