The furnace room is also the laundry room
Typical on a Dale City lower level. Clean the dryer’s lint screen every load, keep bleach and detergent off the furnace cabinet, and don’t hang wet clothes on it.

What it costs
What a furnace tune-up costs in Woodbridge.
$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 Woodbridge
Woodbridge furnaces share rooms with the laundry, walls with snowdrifts and lines with propane.
In Dale City two owner homes in three burn natural gas for heat, and the median owner home dates to 1983. The furnace in a house like that usually stands on the lower level, often sharing the room with the washer and dryer. Lint drifts into the burner area, and a standard furnace that takes its combustion air from the room breathes whatever the laundry gives off. The tech takes the door off, runs it through a whole cycle and writes down what turned up.
The Census place called Woodbridge, the older ground around Route 1, has the largest propane share on a Woodbridge address, about one owner in 22. Propane furnaces are on our list too, just with different numbers: propane reaches the burners at a higher pressure, through orifices sized for it. The tech reads that pressure at the gas valve and holds it against what the maker calls for on propane.
More than four in ten homes in Lake Ridge and in County Center are townhouses. A high-efficiency gas furnace in one often breathes in and vents out through plastic pipes low on an outside wall. Prince William County Fire and Rescue wants furnace vents kept clear of snow buildup during a storm and after it. A drift over those pipes trips the pressure switch, which the tune-up tests on purpose, and the burners stay off until someone digs them out.
Leesylvania and County Center went up mostly after 2000, the median owner home in 2006, and close to two owners in three there heat with gas, so a builder’s furnace has seen about 20 winters. Its readings say more than its age does. In Potomac Mills two owners in three heat with electricity, usually through a heat pump, so the closet often holds an air handler instead of a furnace; the heat pump and its air handler cost $99 to tune up, the same as a furnace.

| Leesylvania | 2006 | single-family houses, about 4 in 10 | gas, about 6 in 10 | The builder’s gas furnaces, many close to 20 years old. |
| Potomac Mills | 1988 | single-family houses, about 6 in 10 | electricity, about 7 in 10 | Mostly heat pumps; furnaces are the smaller share. |
| County Center | 2006 | townhouses, about 4 in 10 | gas, about 6 in 10 | Townhouse furnaces in closets and attics. |

When it’s worth doing
When a furnace tune-up earns its keep in Woodbridge.
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.
You just bought the house
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.

Choosing who tunes it up
How to pick who tunes up your furnace in Woodbridge.
Questions to ask anybody who quotes you, us included.
Will they check that the furnace matches the fuel you burn?
Near Route 1, ask for the gas pressure reading against the propane setting. A furnace converted from natural gas to propane, or back, should carry a conversion label and readings to match.
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.

Questions
Furnace tune-up questions from Woodbridge.
In a Woodbridge rental, is the furnace tune-up the landlord’s job?
Usually. The Code of Virginia has a landlord keep the heating that comes with a rental in good and safe working order, and close to three Woodbridge homes in ten are rented. Owners can book the visit and pass along the tenant’s number; the written findings go to the owner.
Is November too late for a furnace tune-up in Woodbridge?
No, just later than ideal. By November the furnace runs most nights, so anything the tune-up finds gets fixed while you need the heat. Late September and October are the easy window.
How much is a furnace tune-up in Woodbridge?
$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.
Is this the Heating Check or the Clean Heat?
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.
