The furnace only lights on the coldest nights
Behind a heat pump, a propane furnace can go weeks without a start and then get called on all at once. Its first start of the season is a good one to have somebody watching.
A furnace tune-up in Bealeton is $99 a system. Propane outnumbers natural gas here nearly two to one, and we tune up both.

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 Bealeton
Most Bealeton homes burn nothing for heat. About seven owner homes in ten use electricity, mostly heat pumps with electric strips behind them for the coldest hours. The furnaces that burn fuel are in the rest: about one owner home in seven burns propane, a little under one in ten has utility gas, and across all of 22712 propane rises to about one in four.
A propane furnace is set up for its fuel, with smaller burner orifices and a gas valve adjusted to propane’s higher pressure. The tune-up puts a gauge on that valve and checks the reading against the rating plate, then runs a full cycle so each safety has to prove itself. The tank in the yard and its regulators are usually the supplier’s to look after; the tune-up starts at the furnace.
In some of these houses the propane furnace backs up a heat pump. The heat pump handles the mild days and hands off when it gets properly cold, so the furnace can sit unlit through a soft November, then run all night in the first hard freeze. One that has sat since March can have dust on its burners, a mouse nest in the cabinet or a tired igniter. A fall tune-up lights it on purpose, while a problem still means an appointment rather than a cold house.
The heat pumps that warm most Bealeton homes get a fall tune-up too, at the same $99 a system as a furnace, and a boiler or a ductless mini split is the same price. Before the first hard frost the tech runs the backup strips, watches a defrost cycle and checks that the unit changes over cleanly from cooling to heating, the parts a heat pump leans on all winter.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
When it’s worth doing
Behind a heat pump, a propane furnace can go weeks without a start and then get called on all at once. Its first start of the season is a good one to have somebody watching.
Propane runs at a different gas pressure than natural gas, so the tune-up checks yours against propane’s numbers.
A furnace that went in with the house is close to 20 years old on a lot of these streets. That’s the age when inducer motors and control boards start to go, and a yearly look finds the tired ones before a cold night does.

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
A propane furnace runs at a different pressure on different orifices, so a gauge reading only means something beside the right figure. Ask whether the tech checks yours against the propane numbers on its rating plate and writes the reading down.
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.

SwiftPro (Moises) did an excellent job assessing our HVAC system and explaining its current condition. We will likely work with them again in the future.
Questions
Early in the fall, before the first night cold enough for the heat pump to hand off. That handoff can come weeks into the heating season, which is how the furnace gets forgotten.
Yes, one near the bedrooms. Among the safeties a tune-up tests is the one that stops the burners when exhaust isn’t clearing; an alarm keeps watch the rest of the year. The County’s fire and rescue department will help you get one, and the Fauquier County card on this page says how to ask.
$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.
