Heat in The Plains is sized for 17 degrees, and winter here goes colder than that.
Fauquier County’s building criteria set a winter design temperature of 17 degrees, the outdoor temperature a heating system here is sized to carry. NOAA’s 1991 to 2020 normals from Warrenton 3 SE, the nearest long temperature record, put the average January low near 25 and count about five nights a year at 10 or colder. Those nights run a system past its sizing, and that’s when a weak igniter or a tired blower motor gives itself away.
By degree days, a year here asks about four and a half times more of the heat than of the cooling. In late January 2026 an Arctic outbreak brought Extreme Cold Warnings to Northern Fauquier, and a weather station listed as The Plains, a few miles north of town, logged a wind chill of 6 below on February 1 and 5 below a week later. Wind chill is about skin, not houses, but that wind finds every gap.
About six owner homes in ten across 20198 heat with electricity, usually a heat pump. On nights like those it leans on its electric strips and reverses now and then to melt frost off the outdoor coil; the tune-up runs it through that sequence at the same price. The February 2016 ice storm left two to three tenths of an inch of ice across northern Fauquier. If freezing rain glazes the outdoor unit, never chip at the coil; if it won’t defrost, switch to emergency heat and call.
About one owner home in five heats with propane, and utility gas heats just 16 of the ZIP’s 589 owner homes, so gas heat here nearly always means a tank. Many newer ones vent out a side wall through two plastic pipes, and a drift over them shuts the furnace down. After a snow like the January 2016 blizzard, 24 to 36 inches across Northern Fauquier, clear those pipes first.

- A few homes here still burn heating oil. We don’t work on oil burners; a switch to a heat pump or a propane furnace is ours to price.
- Some homes here run on propane, and a propane furnace gets the same tune-up.
What a furnace tune-up costs in The Plains.
$69 for one furnace, regularly $99, 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$69
- Furnace tune-up, regularly$99
- Heat pump, boiler or ductless mini split tune-up, one system$69
- 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 $69 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.
When a furnace tune-up earns its keep in The Plains.
It came back from the last outage acting strange
Short cycling, clicking that never lights, a blower with no heat behind it. Power that drops and returns in a storm can leave a control locked out or a part weakened, and a fall tune-up’s full cycle finds which.
You heat with propane
Propane runs at a different gas pressure than natural gas, so the tune-up checks yours against propane’s numbers.
Before the first cold night
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.

How to pick who tunes up your furnace in The Plains.
Questions to ask anybody who quotes you, us included.
Will they check the backup heat, not just the outdoor unit?
On a heat pump, the strips carry the house on the coldest nights. Ask whether the tech confirms they come on when called for and writes it down.
Do they say what the tune-up checks?
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.
Will they tell you what can wait?
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.

Furnace tune-up questions from The Plains.
The power’s out and the propane tank is full. Why is the house cold?
A propane furnace needs electricity for its blower, igniter and controls, so an outage stops it however full the tank. It should restart on its own when power returns. If it doesn’t, or it lights and quits, call us after a storm and we’ll check it all.
How early in the fall should we book it?
The Warrenton station’s normals put the first fall freeze around November 1, so September and October are the easy months: the heat isn’t needed yet, and a part it finds gets fitted before the frost.
How much is a furnace tune-up in The Plains?
$69 for one furnace, regularly $99, 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.
Is this the Heating Check or the Clean Heat?
No. The furnace tune-up is its own visit at $69. 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.
