Centreville heats with gas, mostly in furnaces on their second or third round.
Close to three quarters of Centreville homeowners heat with gas, against roughly half in Chantilly next door. With the median house built in 1990, the furnace in most of them isn’t the builder’s anymore. It’s the second, sometimes the third, and it often shares a tight utility room or closet with the water heater, a space that tends to double as storage.
That second furnace is often the one that changed the venting. Builders in those years usually ran the furnace and the water heater up one shared metal flue. A high-efficiency replacement vents out a wall in plastic pipe and drains water from a condensate trap, which leaves the water heater alone on a flue sized for two. That’s part of why Fairfax County wants a chimney vent certification whenever a fuel-burning appliance is replaced, and why a plugged condensate trap is enough to keep a newer furnace from firing.
The gas company question is simpler here than in our home town. Fairfax County’s utility list puts most of the county on Washington Gas and names Columbia Gas only for parts of Chantilly and Herndon, so a Centreville gas account, and any gas utility rebate on a new furnace, nearly always runs through Washington Gas.
The other quarter of homes heat with electricity, which usually means a heat pump with backup strips in the air handler. Most of the county buys its power from Dominion Energy, while the county lists portions of Centreville and Clifton on NOVEC, so check which one bills you before weighing a dual fuel setup.
Centreville houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Centreville
- Median home built1990 Census
- Built before 1980about 1 in 10 Census
- Built since 2000about 2 in 10 Census
- Most homes aretownhouses, about 5 in 10 Census
- Heated withgas, about 7 in 10 Census
- Rentedabout 3 in 10 Census
- Most heat here is a gas furnace, so most calls come down to the flame sensor, the igniter, the inducer motor or a pressure switch.
- Townhouse furnaces sit in closets and attics with little room around them, so a clear path to the unit makes the visit quicker.

What a failing furnace in Centreville usually does.
Water on the floor by the furnace
A high-efficiency furnace makes water as it burns and drains it through a trap and a small line, sometimes to a pump. When that clogs, the furnace shuts itself down and the water ends up on the floor. Clearing it is a routine repair.
It lights, then shuts off
The burners fire and go out a few seconds later, over and over. That’s usually a dirty flame sensor, and cleaning it takes about ten minutes.
It won’t light at all
No glow, no flame. A cracked igniter is the usual part, and on a high-efficiency furnace a clogged condensate line can stop it cold too.

How to pick the best furnace repair company in Centreville.
Questions worth asking anybody who comes out, us included.
Will they check the water heater’s flue when the furnace changes?
In a Centreville house from the 1980s or 90s, the two often shared one metal flue. A furnace swap that moves to plastic venting leaves the water heater on a flue too big for it, and the right tech checks that before calling the job done.
Will they price the part before they fix it?
Flame sensors, igniters and control boards all have a going rate. A tech who can’t tell you the number before starting is asking you to find out afterwards.
Do they look at the venting, not just the flame?
Getting the burners lit is half a heating call. Ask whether they check the flue and test for carbon monoxide while the panel’s open.
Do they know when a repair isn’t worth it?
A big repair on a furnace past 15 or 20 years deserves a replacement price next to it. A good tech puts both numbers in front of you and lets you choose.

Heating repair questions from Centreville.
Can the fire department help with a carbon monoxide alarm in Centreville?
Fairfax County Fire and Rescue keeps a limited number of CO alarms for residents who need one, and the local fire and rescue station comes out to install it. Centreville has two, Station 17 on Old Centreville Road and Station 38 on O’Day Drive; requests go to the county’s Life Safety Education section at 703-246-3801. The county puts a plug-in alarm’s life at about ten years, so one that came with a 1990 house is long overdue.
What should I do if I smell gas in a Centreville house?
Get everyone out first, then call 911 or Washington Gas’s emergency line, 703-750-1400, from outside. Don’t flip switches or light anything on the way out. Once the gas company has made it safe, call us about the furnace or whichever appliance it came from.
My furnace and water heater share a small utility room. Is that a problem?
Only if it’s packed or shut tight. Both appliances burn gas and need air to do it, so a louvered door should stay louvered, and the room shouldn’t turn into the place the paint cans and moving boxes live. The county’s clearance rule is in the box above.
How much does furnace repair cost in Centreville?
The diagnostic visit is $99. A flame sensor cleaned is $95 to $180; an igniter or flame sensor replaced, $240 to $410; a control board, $550 to $1,180; a blower motor, $670 to $2,400.
Should I repair it or replace it?
Fix the small parts on almost anything. Before a big repair on an old furnace, look at the replacement number: a furnace alone, keeping the air conditioner you have, runs $4,285 to $14,040 installed, and the HVAC estimator gives your number in about a minute.
