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 Waterford
Propane heats more than half of the owner homes in ZIP 20197, and the Census finds none on natural gas. So a Waterford tune-up is mostly a propane furnace, and the tech holds its gas pressure to the propane number printed on the rating label, not the natural gas figure. About one owner home in six here burns oil. We don’t work on oil burners, so those need another company. Heat pumps, boilers and ductless mini splits are ours, at $99 a system.
The median owner home in ZIP 20197 went up in 1996, so a furnace that came with a house of that age is about thirty years old, and about a third of the owner homes date from before 1980. At that age the igniter and flame sensor tend to wear first, with the draft inducer motor behind them. The tune-up runs the furnace through full cycles and writes the readings down. If a part is tired, the price is on paper before anyone touches it, and you decide.
The Purcellville weather station, about six miles west-southwest of the village, logs 4,942 heating degree days in a normal year and 114.7 nights at or below 32 degrees. In a median year the first 32-degree night of fall lands around October 25, so the tune-up belongs before that date. In January 2026, the coldest nights, the 27th, 30th and 31st, came under Extreme Cold Warnings for Western Loudoun. A furnace that stumbles on one of those means a cold house.
A propane furnace burns its fuel but runs on household power: the igniter, the blower and the control board all need it. Loudoun has lost power to snow and wind before. The February 2010 snowstorm brought outages across the county, and in July 2024 dozens of trees, wires and poles came down near Clarkes Gap Road and Hurley Lane. The tune-up is also the time to check that the furnace starts cleanly and that nothing that can burn sits within three feet of it, the county fire and rescue clearance.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIP 20197 as a whole: every Waterford address, the village included. The Census place for the village alone has too few homes for steady figures.
When it’s worth doing
On a furnace near thirty, long run times are the early warning: the thermostat asks, the furnace runs and runs, and the rooms still trail behind. With 114.7 nights a year at or below 32 degrees at the Purcellville station, that is a lot of hours on the blower and heat exchanger. A tune-up reads the temperature rise while October is still mild.
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.
Safety and paperwork

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
In Waterford that question matters: propane leads, electric and oil follow, and the right gas pressure depends on the fuel. Ask whether the company works on yours. We do propane, heat pumps, boilers and ductless mini splits; oil is not on our list, and you hear that before a visit is booked, not after.
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.

Questions
No. Propane furnace, heat pump, boiler or ductless mini split, it is $99 per system. About 23 percent of owner homes in ZIP 20197 heat with electricity, and the Census counts a heat pump as electric heat, so a good share of your neighbors have the other kind of system.
Loudoun’s fire and rescue system wants a qualified professional to look over the heating equipment yearly, chimney included. That is county guidance, not a permit rule, and a tune-up is how a propane furnace gets its yearly look. Book it ahead of the median first 32-degree night, around October 25.
$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.
