One village, one ZIP, three counties, and nearly every home a house on its own lot.
The village of Amissville is in Rappahannock County, on US 211 in the Piedmont between the Blue Ridge and the Rappahannock River. Its 20106 mail reaches well past it: of about 1,855 homes on that ZIP, the 2020 Census put 54 percent in Culpeper County, 43 percent in Rappahannock and 3 percent in Fauquier.
Nearly every home is a house. In the Census figures for ZIP 20106, 99 percent of homes are single-family detached, with no townhouse rows or condo buildings. So every home has its own heating system, its own water heater and its own drain line, and none of it is shared with a neighbor’s.
The houses span five decades. About 37 percent went up before 1980 and about 30 percent since 2000, and the median owner home dates to 1993. A house from the 1970s has likely replaced its water heater two or three times by now; one from the 2000s is reaching the age when a first heat pump or AC compressor gives out.
The heat comes from a tank or the meter. Owner homes on 20106 heat with propane (about 44 percent), electricity (about 36 percent) or oil (about 13 percent), and only about 2 percent with natural gas. That points to propane furnaces, heat pumps and, in some older houses, an oil boiler or furnace near the end of its run.
Propane, heat pumps and a cold Piedmont winter, from the village to the county lines.
Two SwiftPro teams come out to Amissville from our Chantilly shop: one for heating and cooling, one for plumbing.
Heating
The nearest NOAA normals station, Boston 4 SE in Culpeper County about 10 miles away, averages 121 nights a year at or below freezing and about seven and a half at 10 degrees or colder, with a median last freeze around April 21. On January 7, 2014 it fell to 12 below zero. A heat pump here needs backup heat that works, or a propane furnace paired with it. We service and replace both; oil equipment isn’t ours, but moving a house off oil is.
Cooling
That same station averages about 22 days a year at 90 degrees or more, and in July 2011 the Weather Service estimated heat indices over 110 across the Rappahannock zone. Most homes cool with a heat pump or central AC on the house’s ductwork; where a room never got ducts, a ductless mini-split fills in.
Plumbing
If your house is on a well and a septic tank, the well, its pump and the tank belong to those trades. From the pressure tank to the fixtures and back out the drain, it’s ours: supply lines, the water heater, faucets and toilets, and the drain line toward the tank. Tell us your county when you call, because the permit office changes with it.
One price book on every side of the county line.

Three counties, three permit offices, one set of Virginia code rules.
Your water
We found no water utility that publishes a report or a hardness figure for Amissville, so if your house is on a private well, your own test is the number that counts. Hard water leaves sediment in a tank and scale in a tankless heater; once you know yours, we can tell you how often a flush or descale makes sense.
Your permit office
It depends on your side of the line. In Rappahannock County, around the village, the Building Office at 311 North Gay Street in Washington issues permits and has its own trade permit application. On the Culpeper County side, the Building Department at 302 North Main Street in Culpeper takes applications online or in person and wants a zoning permit first. The few Fauquier County homes go through Fauquier’s Community Development office.
The Virginia rules
Whichever county you’re in, the Virginia building code sets two rules that matter for a heating job. Replacing a gas, propane or oil furnace or boiler takes a permit; only equipment fueled some other way can be swapped without one. And if a tank bursts, the replacement can start first, as long as the application reaches the county office by the end of the next working day.

The village on US 211, and the ZIP that runs well past it.
In the village: US 211, Lee Highway, through Amissville in eastern Rappahannock County. Around it: the Culpeper County roads on 20106 mail, out toward Jeffersonton and Rixeyville, and the small Fauquier County slice across the river. Next door:
Amissville questions.
My address says Amissville. Which county am I in?
Check your tax bill or your deed, because the ZIP won’t tell you. By the 2020 Census, about half the homes on 20106 are in Culpeper County, about four in ten in Rappahannock, where the village is, and a few in Fauquier. It matters for us because the permit for a furnace, a propane line or a water heater comes from that county’s office.
Storms keep dropping trees out here. What should I check after one?
Look at the outdoor unit before you turn the heat pump or AC back on: limbs on it, bent fins, a unit shoved off its pad. On June 22, 2022, a storm brought down hundreds of trees, branches and wires between Amissville, Jeffersonton and Rixeyville in about ten minutes, and trees came down on Lee Highway in June 2016 and across Amissville in August 2020. If a limb hit it or water reached it, have it checked before it runs.
Can a heat pump keep up with an Amissville winter?
A modern one can, with backup heat that works. The Boston 4 SE station averages a January low near 23 degrees and about seven and a half nights a year at 10 or colder, and the Christmas 2022 cold front dropped the Sperryville station from 32 to 4 degrees in a day. Those are the nights the backup strips or a paired propane furnace carry the house, so test the backup before winter instead of finding out in January.
What does a heat pump or AC repair cost in Amissville?
The same book as every town we serve, on any side of the county line: a $99 diagnostic, then $240 to $370 for a run capacitor, $190 to $740 to add refrigerant or $175 to $420 to clear a clogged condensate drain. Tell us the county and whether the backup is electric strips or propane, and we’ll show up with the right parts.
