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 Paeonian Springs
Three in four owner homes in ZIP 20129 date from 1980 or later, with a median build year of 1997, so most have ducts drawn in with the plans. A mini split goes where those plans stopped: a room added afterward, a garage bay turned into an office, a space at the far end of a long duct run. Nothing in the Census says which of the roughly 150 owner homes have such a room, so that question is yours to answer.
About one owner home in six predates 1960, and about one in four predates 1980. A house from before 1960 may have been built with radiators or baseboards and no ducts. Central air there means cutting chases through finished walls, while a mini split needs a small hole for the line set. Oil heats nearly one in five owner homes, and where it feeds a hot-water boiler the house often has no ducts to cool through.
Electricity heats just over a third of the owner homes, which can mean baseboard strips as well as heat pumps, and a ductless head heats as well as cools. For a baseboard room, one wall unit does both jobs. Propane heats nearly half, and in those houses a head is a way to cool a room the furnace’s ducts reach poorly, with the furnace left to do what it does.
July’s average high at the Purcellville station is 86.4, and it logs about thirty days a year at 90 or above, which is when a top-floor bedroom or a room over a garage runs hot. The outdoor unit needs a clear spot. Storm winds dropped dozens of trees near town on June 2, 2022, and again on July 15, 2024, so the unit belongs away from the limbs, on a bracket that holds it above the snow.
When it’s the right call
A room that stays warm in July while the thermostat elsewhere reads fine has an air supply problem the thermostat can’t see. Lowering the setting for one room’s sake cools the other rooms more than they need. A ductless head cools that one room alone and leaves the rest of the house on its own schedule.
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.
Choosing who installs it
Questions worth asking anybody who quotes you, us included.
The indoor head is the easy part. Ask where the refrigerant line runs from head to outdoor unit, which wall it passes through and where the unit stands. On a detached house with its own lot there is room to place it well. A quote should name that route in writing before the work starts.
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
Each room you want covered gets its own indoor head, and the price climbs with the count: $11,000 to $15,000 for two rooms, $12,500 to $18,000 for three and $16,000 to $21,000 for four, all installed. Five or six rooms land at $19,000 to $25,000 and $23,000 to $30,000. The estimator quiz asks about your house and narrows the range.
That is the house a mini split suits best. Older houses, about one in six here predating 1960, often have hot-water radiators or baseboard and no ducts, and cooling them through ducts means opening walls. Each room that needs cooling gets a head. One room is $7,000 to $10,000 installed, and the estimator quiz narrows that to your house.
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.
