Heat pump repair in Alexandria.

About four in ten owner homes inside the City of Alexandria heat with electricity, and more than half of all the City’s homes are in condo and apartment buildings. Put those together and a lot of our Alexandria heat pump work happens indoors, in a closet off a hallway, with the outdoor half somewhere the owner rarely sees: a roof, a garage level, a pad behind the building. Before we can test anything, someone has to let us reach it.

Old Town and Parker-Gray add their own wrinkle. Where outdoor equipment sits, and how it’s screened, is something the City’s Board of Architectural Review weighs there, so on a narrow rowhouse the unit often sits on a flat rear roof reached by a hatch or a ladder, or wedged into a side passage barely wider than the cabinet. Tell us where yours is when you call. A roof unit in January with ice on the shingles is a different visit from a pad in the yard.

Ford’s Landing, the brick townhouses on the river south of Old Town, is the cautionary tale. A 2009 City staff report notes those homes were built with through-the-wall units that failed at a high rate, and moving a replacement to a new spot went to the Board of Architectural Review one house at a time. Fixing a unit where it already sits is a service call. Relocating it in a historic district is paperwork first.

In the City’s older detached houses, Del Ray and Rosemont among them, the heat pump almost always came decades after the house, with ducts snaked through an attic that was never meant to hold them. Those runs leak and lose heat, so a pump that tests fine can still leave the far bedroom cold. On the county side, Groveton and Hybla Valley lean more toward 1980s townhouses with the air handler upstairs and the pump on a small pad out back.
