Around Orlean the houses came in two waves, out among the farms. The Census block group centered on the village counts 140 homes built in the 1970s and 169 in the 1990s, out of 576, every one a detached house. A 1990s house here is likely on its second furnace and air conditioner or about due, and a 1970s house has usually been through two sets, still on the ductwork it was framed with.
Only some of those houses have a furnace and an air conditioner. Electricity heats 306 of the block group’s 543 occupied homes, mostly by heat pump, a different job at $8,499 to $21,650 installed. The furnace and AC pair is the propane house’s setup, 95 homes here. There the cooling coil sits on top of the furnace, so when both halves are the same age, doing them together opens that closet once.
The cooling half works harder than people guess this far out. Warrenton 3 SE, the nearest station with thirty-year normals, averages close to 21 days a year at 90 degrees or hotter, and the July 2019 heat pushed heat index values past 110 across northern Fauquier. A house on open ground takes the afternoon sun full on. Size both halves from one load calculation: the 17 degree night Fauquier County sizes heat to, and the 90 degree afternoon.
Storms settle some of these replacements. On June 22, 2022, gusts estimated at 80 to 90 miles an hour reached Orlean, bringing down thousands of trees; at least three buildings collapsed under them. A limb across a condenser can flatten the coil or crack a refrigerant line. After a storm, switch the cooling off at the thermostat, look at the outdoor unit before it runs, and call us to check it all. On a unit near twenty, a crushed coil usually starts the replacement talk, with the furnace under it priced alongside.
