The window units go in every June
If the bedrooms cool with window units every summer, the house likely heats with a boiler and never had ducts to begin with. Heads on the walls clear the windows and give each room its own setting.

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 McLean
Boiler houses with no ducts and 1950s houses that grew: ductless in McLean.
McLean is where we see boilers most. Hot-water heat is a regular part of our McLean heating work, far more than anywhere else we go. A boiler warms the house through radiators or baseboard, so a home built around one may have no ductwork at all, and the summer plan is window units or a duct system squeezed into the attic later. Ductless heads are a third way: a head high on the wall in every room that needs cooling, a slim line set out to the unit outside, and no new ducts or soffits.
Cooling a whole boiler house this way is a multi-zone job, a head for each room with a door that stays shut, served by one outdoor unit or two. Four zones run $16,000 to $21,000 installed. Each head heats too, so on a cool October morning it can take the chill off a room before the boiler season starts.
Close to four homes in ten in 22101 went up in the 1950s and 60s, and a house from then that has since gained a wing, a suite over the garage or a lower level finished as an office often has rooms its first duct layout doesn’t reach. In the bigger houses, nine rooms or more at the 22101 median, the trouble spot is often the room at the end of the longest duct run: a guest suite, a home gym, a corner office.
22102 is the opposite case. Close to half its homes are in buildings of 50 units or more, where an outdoor unit and a hole through an outside wall are the building’s decision, so in Tysons a mini split is mostly a townhouse or house job. If you’re in a tower and want one, management’s written approval comes before any price.

When it’s the right call
When a ductless mini split makes sense in McLean.
You’re in a condo
An outdoor unit on a condo building usually needs the association’s approval first, and some buildings say where it can go. Ask before you price one.
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 McLean.
Questions worth asking anybody who quotes you, us included.
Did they map the line set route outside?
With heads in three or four rooms, the refrigerant lines have to come down the outside of the house to the outdoor units. Get the route marked and the line covers named before signing, especially on a side the street sees.
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 McLean.
Our boiler house has ducted AC upstairs only. Can ductless cool the main floor?
Yes. If the ducts from an attic air handler only reach the second floor, the main floor has no cool air path at all. Heads in the living and dining rooms fill that gap without cutting into ceilings, and two zones run $11,000 to $15,000 installed.
How much does a ductless mini split cost in McLean?
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.
