Nine in ten owners or more heat with gas in Kings Park, North Springfield and Ravensworth, so the cooling there is an air conditioner that sits idle from October to May. Seven months parked is hard on a condenser too: leaves pack against the fins and stay damp, a wasp or a mouse may move into the cabinet, and the foam sleeve on the larger copper line dries out in the sun. The spring visit clears out what the winter left.
Those are the town’s oldest streets, with typical owner houses from 1957 in North Springfield, 1964 in Ravensworth and 1966 in Kings Park, so the air conditioner is rarely the first. Its copper lines were often threaded through after the walls were closed, along a basement ceiling and out through the foundation. Where the insulation on the cold line has slipped or split, bare copper sweats every humid day, and under a finished ceiling that becomes a brown stain on the drywall.
Around Newington it’s the other way. About three in four Newington Forest owners and close to six in ten in Newington heat with electricity, usually a heat pump, where the typical owner’s home dates from the early 1980s and about half are townhouses. By April that heat pump’s outdoor unit has already worked a full season, icing up on raw mornings and melting itself clear. The written findings tell you how the winter treated it.
Springfield proper, along Backlick and Old Keene Mill Roads, mixes it all: about a quarter of its homes are in condo and apartment buildings, and about a third are rented. Fairfax County’s property maintenance code wants heating and cooling kept in safe working condition in every rental and owned home, whatever the date. For a landlord, a spring tune-up shows where the cooling stands before a tenant’s first hot week.
