Leesburg homes, old and new.
Ductless mini-splits for older homes, plus heating and AC repair, new systems and water heaters across Leesburg.

Leesburg has two kinds of houses that need two different answers. In and around the historic downtown, many homes were built long before central air, and adding ductwork means tearing into plaster and trim. Out in the newer neighborhoods, it is standard forced air that just needs good repair and maintenance.
For the older homes, a ductless mini-split is often the right fix. A slim line set runs outside, each room gets its own head, and the walls stay intact. For the newer homes, we do everything from tune-ups to full replacements.
Leesburg is about 30 minutes from our Herndon base by Route 7 or the Dulles Greenway.
The houses in Leesburg
Downtown Leesburg's historic district has houses from the 1700s and 1800s alongside early 1900s homes, many heated by radiators or added-on systems. Neighborhoods like Lansdowne, River Creek and the developments off Route 15 and Battlefield Parkway date from the 1990s onward, with standard forced air and attic or basement air handlers.
What the weather does to systems here
Older Leesburg houses can lose a lot of heat through original windows and thin walls, which makes room-by-room ductless control especially useful. Newer homes here see the same humid summers as the rest of Loudoun, so clean coils and clear condensate drains matter.
