One twenty-year building wave, now wearing out on the same clock.
Fairfax County dates old Centreville to a 1792 town on Braddock’s Road. Almost every house you’d call us to came two centuries later.
The numbers. The Census puts the median owner-occupied Centreville home at 1990, with about seven in ten built between 1980 and 1999 and only about one in ten older than that. Nearly half of all homes here are townhouses, and close to three quarters of homeowners heat with gas. Chantilly, one town up Route 28, runs the other way: mostly single-family houses, with the heat split close to half gas and half electric.
What that puts in the utility room. A gas furnace and a gas water heater side by side, usually the second set the house has owned. Supply pipe from the stretch of years when grey polybutylene was going in. And a pressure reducing valve on the main, which Fairfax County’s plumbing code has required since December 4, 1972, so close to nine in ten houses here were built with one.
Centreville is where water treatment questions come up most for us. Fairfax Water describes its own water as moderately hard to hard, and the white crust on a shower door is the calcium it’s talking about.
Heat, cooling and pipes, one phone call.
A dedicated HVAC team and a dedicated plumbing team, both working out of our shop on Lafayette Center Drive in Chantilly.
Heating
Mostly gas furnaces on their second or third round, plus a quarter of homes on electric heat, which usually means a heat pump. Replacing a gas furnace takes a Fairfax County permit and a chimney vent certification, like for like or not. The Centreville furnace repair page has the repair prices.
Cooling
Behind the townhouses the condensers stand in rows, a lot of them past their first replacement. The everyday AC repairs are priced on the Centreville AC repair page, and duct cleaning and dryer vent cleaning have pages of their own.
Plumbing
Houses from the 1980s and early 90s sit in the polybutylene window, so it pays to know what your supply pipe is. The pressure reducing valve on the main is yours to buy and keep up, and so is the whole sewer lateral, out to the county main under the street.
The number first, then the work.

One county and one water company behind every Centreville address.
Your water
Fairfax Water, for both ZIP codes. Its FAQ calls the water moderately hard to hard, typically 5 to 10 grains per gallon, shifting with location and rainfall; the 2025 plant report is linked just below.
Reports: Fairfax Water, 3 to 10.8 gpg.
Your permit office
Fairfax County, for both ZIP codes. Gas appliances need a permit even like for like; Virginia’s code exempts an electric water heater or heat pump replaced in place, but the County’s own permit list still names those replacements, so we pull the permit. A job that adds new gas piping, like a tankless conversion, goes in as a residential plumbing permit.
Permit pages: Fairfax County.
Your sewer line
Fairfax County puts the whole lateral on the homeowner, from the house to the county main, under the street included. Replacing it takes a county plumbing permit, plus a VDOT permit when the road is a state road.

What our customers say.
I needed emergency plumbing and AC services and they made it happen immediately.
Fast service and very knowledgable. The technician helped me with both a garbage disposal and water softer issue. He was friendly and easy to talk to about future needs.
SwiftPro HVAC came out to do a plumbing maintenance check. The check was included with my recent new HVAC installation. The technician (James Milligan) was very professional and quickly evaluated my faucets, toilets, water heater, washing machine lines, main water intake valve, all cut-off valves and visible pipes. Now I have an estimate for needed maintenance repairs.

Centreville questions.
Who supplies electricity in Centreville?
Most of Fairfax County is on Dominion Energy, but the county’s own utility list says portions of Centreville and Clifton get power from the Northern Virginia Electric Cooperative, NOVEC. It changes nothing about a repair. It does decide your electric rate, and which utility’s rebate applies if a heat pump is part of the plan.
Who pays for the pressure reducing valve on a Centreville house?
The owner. Fairfax Water’s rules make the valve the customer’s to buy, install and maintain, and Fairfax Water only supplies one for a house built before December 4, 1972 that sees more than 80 psi, or where its own changes raised the pressure. Only about one Centreville home in ten predates 1980, so here the valve is nearly always yours.
Could a 1990 Centreville house have polybutylene?
Yes, and the median owner home here is from 1990, right in the middle of the years it was used. Check where the supply lines come out of the floor under a sink or leave the water heater: grey plastic, often stamped PB, is the giveaway. It’s known for giving out at the fittings, and SwiftPro’s repiping guide covers what replacing it involves.
Is Centreville on Washington Gas or Columbia Gas?
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 is almost always Washington Gas. If you smell gas, leave the house first and call 911 or Washington Gas at 703-750-1400 from outside.
How old is the oldest part of Centreville?
Residents petitioned for a town called Centreville in 1792, and Fairfax County protects what’s left of it as the Centreville Historic Overlay District, where the Confederate commanding general used Mount Gilead as his headquarters through the first winter of the Civil War. The county’s guidelines close the district’s story in 1956, the year of the federal highway act; I-66 later went in just north of it, and the Centreville most people live in grew up after that.
