Book your furnace tune-up
Marshall gas furnaces run on propane, in village cellars and basements on damp ground.
Only about eight owner homes in all of 20115 heat with utility gas, so a Marshall gas furnace runs on propane from a tank in the yard: about one owner home in five, a bit over 400 houses. Most of the rest heat with electricity, usually a heat pump, and a heat pump gets the same fall tune-up for the same $69 a system.
In the village, the furnace is younger than the house by generations. The County’s plan lists stone, frame and brick buildings on West Main Street from the early 1800s and two-story I-houses from 1900 to 1920. A propane furnace in one of those often sits in a cellar and vents up an old masonry chimney, which spends the summer collecting leaves, crumbled mortar and the odd nest. Among the safeties the tune-up makes prove itself is the switch that shuts the burners down when exhaust isn’t clearing.
Marshall’s ground adds wear of its own. The plan maps soils with a seasonal high water table 10 to 40 inches down and says houses with basements there should be sited to keep groundwater out. A furnace on a floor that’s damp half the year rusts from the bottom, and the scale can drop onto the burners. The tune-up looks at the burner compartment and the cabinet base; if the furnace ought to be raised onto a pad, that goes in the findings with a price.
North of Main Street and west of Rectortown Road, where most houses date from the 1970s through the 1990s, a propane furnace there is often the house’s second or third. Fall is when field mice look for somewhere warm, and a quiet furnace cabinet suits them; a nest by the blower or a chewed control wire is what a fall look finds before a cold night does.

What a furnace tune-up costs in Marshall.
$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 Marshall.
Rust flakes on the floor under the furnace
Orange flakes under the cabinet or a rust line around its base mean water has been getting at the furnace, from a damp floor or the cooling coil dripping above it. The burners sit right there, so book the tune-up before the heat is needed.
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 Marshall.
Questions to ask anybody who quotes you, us included.
Do they look at where the exhaust goes, not just the burners?
On a furnace venting up an old village chimney or out a basement wall, the vent decides whether exhaust leaves the house. Ask whether the tech looks at it and writes down what they saw.
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 Marshall.
When should a Marshall propane furnace get its tune-up?
Pick a mild week in September or early October, before the furnace is counted on every evening. A part found on its way out can then be replaced before a cold snap.
If the tune-up says my propane furnace is done, what comes next?
A written price, and no rush to decide that day. A new propane furnace needs a Fauquier County permit even as a straight swap, because it burns fuel, and the County issues trade permits over the counter in Warrenton. The HVAC replacement estimator shows an installed range first.
How much is a furnace tune-up in Marshall?
$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.
