Price in writing firstYou see every option priced before anything is ordered
What it costs
$99 for one furnace, anywhere we work. The tech checks the gas pressure, the temperature rise, the safeties and the sequence of operation, which is the order the furnace lights, heats and shuts down in. A repair it turns up gets a written price first, and you decide.
Furnace tune-up, one system
$99
Heat pump, boiler or ductless mini split tune-up, one system
$99
Comfort+ membership, a heating maintenance visit every fall included
$199 a year
It’s priced per system, so a house with a second furnace for the upstairs is two tune-ups. A heat pump, a boiler or a ductless mini split is the same $99 a system.
With Comfort+ membership, $199 a year or $20 a month covers four visits every year: a heating maintenance visit in the fall, a cooling maintenance visit in the spring, a dryer vent cleaning, and a water heater flush with a sewer camera inspection. We book each one when it’s due.
What’s different in Amissville
Propane is the heat in about four owner homes in ten in ZIP 20106. Electricity is next, a bit over a third, then oil at about one in eight and utility gas at about two in a hundred. So the furnace on the tune-up list here is most likely a propane one, and it has its own numbers: a higher manifold pressure than a natural gas furnace, and a gauge reading that only means something against the figure on its own rating plate.
Oil is the one fuel we don’t work on, so if you’re among the one in eight on oil, an oil service company is who you want. A heat pump, a boiler or a ductless mini split gets a tune-up at $99 a system, and the electric houses, a bit over a third of the ZIP, are covered the same as the propane ones.
This is a real heating climate. The Boston station, 10.3 miles south-southwest, counts 4,836 heating degree days a year, about 120 nights at or below freezing and a January average low of 22.9 degrees. Cold snaps cut deeper: 12 below zero there on January 7, 2014, and 3 degrees at Sperryville on January 27, 30 and 31 of 2026, under Extreme Cold Warnings.
The first 32 degree night comes around October 22, the Boston station’s median, so September into early October is the tune-up window. A furnace that has been off since spring has to prove itself on the first cold night; the tune-up makes it prove itself on a mild day instead. Anything it finds is priced in writing before work starts, and you decide.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIP 20106 as a whole: about half its homes are in Culpeper County, about four in ten in Rappahannock County, where the village is, and a few in Fauquier County.
When it’s worth doing
A furnace that lights, runs briefly and quits is often a flame sensor coated in residue. Cleaning it is a small fix. If it happens on the first cold night you have a cold house and a wait; if it happens at the tune-up it’s a line on the list.
Propane runs at a different gas pressure than natural gas, so the tune-up checks yours against propane’s numbers.
That’s the night every furnace in town gets asked to work at once. A tune-up in the fall finds a weak part while you still get to choose when it’s fixed.

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
A propane furnace takes a different gas pressure and different burner orifices than a natural gas one, so a gauge reading is only good against the right figure. Ask the tech to read you the number off the rating plate and the number off the gauge. In ZIP 20106 propane is the usual furnace, not the odd one.
Ask before anyone comes out. Gas pressure and temperature rise are readings on a meter, so a real tune-up has numbers in it, not just a look at the filter.
Some tune-ups end in a list. Ask which items are failing now, which can wait a season, and what each one costs, before you agree to any of it.

Elvis Diaz from SwiftPro did a fantastic job of inspecting my HVAC system, he explained everything in a very professional way, for example, he recommended the right filter type to use. It is a job well done.
Questions
Under Virginia’s building code the exemption for replacing a mechanical appliance stops at gas and oil, so in Rappahannock County and Culpeper County a gas or propane furnace swap is permit work. Fauquier County wants a permit for any fuel-fired appliance, even in the same spot. Which one applies depends on your side of the ZIP.
A working one near the bedrooms makes sense in any house that burns fuel, propane included. A furnace tune-up tests the safeties inside the furnace; an alarm covers the rest of the house. On the Fauquier County side, county fire rescue takes requests for smoke and carbon monoxide alarms through a form on its Public Education page.
$99 for one furnace, and the same for a heat pump, a boiler or a ductless mini split. If it turns up a repair, you get the price in writing before any work, and you decide.
No. The furnace tune-up is its own visit at $99. The Heating Check and the Clean Heat deep clean, the one that takes the blower wheel out and cleans it, are separate offers with their own terms on our Clean Heat page.
