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 Quantico
Houses from before 1940 make up about a quarter of the Town’s stock, and in them central air came decades after the plaster. County address records date at least nine of the 13 homes on 5th Avenue to before 1940, and two on 3rd Avenue to 1918. Running new ducts to a bedroom means opening ceilings that old. A wall head in that room, with a small outdoor unit, leaves the plaster and the existing system alone.
More than half the Town’s 370 homes are in duplexes and small apartment buildings, and 260 of the 310 occupied homes are rented, so the person approving a mini split is usually the owner. For an owner, one head in a unit that runs too hot or too cold, while the rest is fine, can be a smaller job than redoing the whole system. A renter can show the owner the room, the wall and the spot outside.
In the Town of Quantico, the county’s Building Development Division issues the building and trade permits, and the Town handles its own zoning approvals. So settle the outdoor unit’s spot first, with whoever owns the building, and ask who files before anything is ordered. The Census survey counts about 120 occupied homes in the Town on electric heat, and a mini split is a heat pump in a room-sized package.
The air station’s January average low is 28 and its July average high is 88, with roughly 30 afternoons a year at 90 or more. A head in the one problem room can be set apart from the rest of the house all year. After the 66 mph derecho gust in June 2012 and a tree down on Fuller Road in August 2021, keep the outdoor unit clear of overhanging limbs.
When it’s the right call
A room at the end of a long duct run, or one added after the system was built, gets what is left of the air. With July afternoons averaging 88 and January nights averaging 28, that room feels both extremes first. A head sized for the room gives it 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.
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.
In a rental, the owner has to agree to a hole in the wall and a unit on the ground. Ask for both spots to be marked on the quote before the price is final, with the owner’s approval, so the job doesn’t stall at the property line.
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.

No. Liberty Military Housing owns, manages and maintains the family housing aboard the base, so changes to heating and cooling go through Liberty or the base Family Housing Office. Prince William County says it doesn’t serve federal property. Houses and apartments in the Town of Quantico are the ones we price.
A duplex half with a living room and a bedroom is two zones, so the figure is $11,000 to $15,000; with a second bedroom, three zones is $12,500 to $18,000. Both halves, four rooms in all, come to $16,000 to $21,000. The estimator quiz gives your own building its number.
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.
