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 Fairfax Station
Nearly every Fairfax Station home is a single-family house, about 8 in 10 built from 1980 to 1999, and in plenty of them the basement was finished years later around the furnace. It ended up in the one unfinished room left, behind a door, sharing it with the water heater and whatever didn’t fit in the closets. Washington Gas says never to close a gas furnace into a small room without openings for air, because a burner short of air can’t burn cleanly. If that door is solid and usually shut, tell the tech.
About 9 in 10 homes in 22039 have four bedrooms or more, more than twice the Fairfax County share, and a house that size often heats its bedroom floor separately. When that second system is a gas furnace, it usually sits in the attic, venting through the roof, and goes years without anybody opening it. Each furnace is its own tune-up at $99; book both before the first hard freeze.
Propane is the other fuel out here: about 200 owner homes in 22039 heat with it, usually from a tank in the yard. A propane furnace gets the same tune-up at the same price, but it runs a higher pressure at the burners than one on Washington Gas, and one converted from natural gas should carry a label saying so. The tank, its regulator and the line to the house are usually your supplier’s. Check the gauge first; the furnace has to fire for the tune-up to mean anything.
Not every 22039 house has a burner to tune. In the Fairfax Station Census place close to half the homeowners heat with electricity, usually a heat pump, while South Run and Crosspointe run nearly 9 in 10 and about 8 in 10 on gas. Unsure which you have? A furnace burning gas or propane has a vent pipe running out of it, and a heat pump’s air handler doesn’t. Either one gets its fall tune-up at $99 a system.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and what that usually means for a tune-up.
| Place | Median home built | Most homes are | Heated with | What the tune-up usually meets |
|---|---|---|---|---|
| Fairfax Station | 1982 | single-family houses, about 9 in 10 | gas, about 5 in 10 | 1980s and 90s houses, most on their second gas furnace. |
| South Run | 1988 | single-family houses, nearly all | gas, about 9 in 10 | 1980s and 90s houses, most on their second gas furnace. |
| Crosspointe | 1993 | single-family houses, nearly all | gas, about 8 in 10 | 1980s and 90s houses, most on their second gas furnace. |

When it’s worth doing
After months off, dust on the burners and the heat exchanger burns away the first time the furnace fires, and the smell fades after a few hours of running. If it lingers, book the tune-up. If it smells like rotten eggs instead, that isn’t dust: leave the house, call 911 from outside, then Washington Gas or your propane supplier.
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.
The home inspector ran the heat for a minute. A tune-up runs it through a full cycle with the panel off, and tells you what the last owners left you.
Safety and paperwork
Fairfax County Fire and Rescue says to have the heating system cleaned and checked by a professional every year, and to keep anything that burns at least three feet from the furnace and the water heater. Source.

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
Ask before booking whether the tech works on propane furnaces and carries a gauge to read the burner pressure. A furnace set up for the wrong gas can still light and run, so the reading, held against the number on the rating plate, is what tells you it’s right.
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
Not always. Two thermostats can mean two separate systems, or one furnace with dampers in the ducts sending heat to each floor. Two furnaces are two tune-ups; one furnace with zone dampers is one, at $99. If the second system is a heat pump, it’s a tune-up of its own at the same $99.
$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.
