Price first: a heat pump and air handler runs $8,499 to $21,650 installed, and our estimator quiz sorts out where your house lands. Electricity heats 54 percent of the owner homes in ZIP 20135, the largest slice, and heat pumps are filed under electricity in the Census. In those houses a heat pump is often the whole system, its outdoor unit working through summer and winter alike. Wood or another fuel heats 24 percent and propane 14.
Cold is the question on this slope. January lows average 22.3 degrees at Mount Weather and 24.5 at Purcellville, which stands in for the village, and the two stations log 104.7 and 114.7 days a year at or below 32. Heating degree days total 5,302 up the mountain and 4,942 in the valley. A heat pump carries the mild stretches well; on the coldest nights its electric strips, or a propane furnace beside it, finish the job, and the quote should name which.
Snow decides where the outdoor unit goes. The 2016 blizzard left 36.6 inches near Bluemont, and February 2010 left 30.1 inches in the village. A unit on a low pad can end up under a drift, where it cannot breathe or defrost. And with electricity as the only fuel, an outage like the ones Loudoun County saw in February 2010 takes the heat with it, so ask what the house has for backup.
About one owner home in seven burns propane, and there a heat pump usually joins the furnace in place of the air conditioner. A furnace and air conditioner pair runs $8,898 to $23,000 for comparison. If oil is what you burn now, about 4 percent of owner homes, the burner itself is not our work, but replacing it with a heat pump system is. Either way the first step is an honest look at the ducts the new air handler will use.
