Most of Georgetown's housing stock predates electricity, let alone central air, so the brick Federals and Victorians along O, P, and Dumbarton Streets were never plumbed for ductwork. That leaves window units in summer and radiators or space heaters in the rooms they can't keep up with. A ductless mini-split solves both at once: a slim indoor head delivers heating and cooling to a single room, and a compact outside condenser feeds it through a refrigerant line about three inches across — no chases cut through original plaster, no soffits dropped below your crown molding, no closets surrendered to a duct trunk. For a house whose interior is the asset, that matters.
What actually makes or breaks a Georgetown install isn't the equipment — it's where the outdoor unit goes. Inside the historic district, anything visible from the public right-of-way falls under Old Georgetown Board review, so we plan condenser placement around rear courtyards, side areaways, flat-roof setbacks, and fence lines that keep the hardware off the street face. We run line sets behind downspouts and through mortar joints rather than across the brick, paint the cover channels to match, and seal every penetration so the facade reads exactly as it did before. The goal is a home that's quietly comfortable and looks untouched from the sidewalk.
Georgetown note: Because Georgetown's rear yards and areaways are narrow and often shared along a party wall, condenser siting is the real puzzle here — we frequently use low-profile or wall-mounted units, sound-dampened pads, and concealed line routing so a single small footprint serves a multi-zone, two- or three-story Federal floor plan without drawing a neighbor's complaint or a historic-review flag.

What It Costs
In Washington, DC, a single-zone mini-split installation typically runs around $3,500 to $6,000, while multi-zone systems serving several rooms often land in the $8,000 to $15,000 range depending on the number of heads, equipment efficiency, and how the line sets need to be routed. Many DC homeowners recover roughly 50 to 75 percent of that cost through energy savings and rebates over time.
