Clifton boilers live in the town’s old houses, and the Town signs off before the County permits.
Inside the Town of Clifton the typical owner home dates from 1945, and about three in four predate 1980. Heat there is a mix: electricity leads, with about one in five owner homes on propane, about one in five on oil, and about one in ten on gas. A hot water boiler in one of those houses is likely on propane, and the gas and propane ones are the ones we work on.
Outside the town line, ZIP 20124 is a different place: 4,459 owner homes, close to eight in ten built in the 1980s and 1990s, the typical one in 1988, with gas heating about six in ten. Gas furnaces in the subdivisions off Springstone Drive and Union Mill Road are the usual heat there, and a boiler is the odd one out.
Inside the town line, a gas or propane appliance swap takes two approvals. The Town signs off first, by letter, and Fairfax County won’t move the appliance permit until that letter is uploaded to the record, with a chimney vent certification alongside it. The whole town is the Clifton Historic District, so a new wall vent for a condensing boiler at $12,782 to $16,500 installed is an exterior change that needs a certificate of appropriateness from the Architectural Review Board.
NOVEC brings power into town mostly on poles and overhead lines, and a boiler needs electricity for its circulator, igniter and controls whatever fuel it burns, so a storm that drops a line stops the heat too. Fire and rescue for the town comes from Fairfax County’s Station 16 on Chapel Road, and the County’s CO program covers town residents: an alarm on every floor and gas appliances inspected each fall.
Clifton houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
The Fairfax County side of 20124
Clifton mail outside the town: five- to ten-acre lots in the Occoquan watershed on Clifton, Compton and Yates Ford Roads, mostly on septic, and the 1980s subdivisions off Springstone Drive and Union Mill Road on county sewer.
ZIP 20124 as a whole, the Town included: its own homes are too few for steady Census figures.
- Median home built1988 Census
- Built before 1980about 1 in 10 Census
- Built since 2000about 1 in 10 Census
- Most homes aresingle-family houses, about 8 in 10 Census
- Heated withgas, about 6 in 10 Census
- Rentedabout 1 in 10 Census
- A few homes here still heat with oil. We don’t work on oil boilers; a switch to a heat pump or a gas or propane boiler is ours to price.
- Most houses built here since about 1980 heat with forced air, so a boiler on these streets is usually in one of the older houses or a custom home.

What your boiler is telling you in Clifton.
Two approvals before the swap
Inside the town line a replacement’s paperwork starts with the Town’s letter, so a boiler that’s failing slowly is worth replacing on a date you pick rather than in a January emergency, when the letter and the permit still have to catch up.
What the county says about boilers in Clifton.
Town of Clifton
Inside the town line a gas or propane water heater or furnace swap still takes a Fairfax County permit, even like for like, with a chimney vent certification. Fairfax County won’t move the application until the Town of Clifton’s own approval is uploaded to it. Source.
The county’s carbon monoxide program covers town residents: an alarm on every floor, gas appliances inspected each fall, and a limited supply of alarms for residents who need one, put up by the local station, which for the town is Station 16. Source.
Fire and rescue in the town comes from Fairfax County’s Station 16 on Chapel Road, and the county’s heating advice applies on every fuel: a professional cleaning and check once a year, and three feet of clear space around the furnace and the water heater. Source.

Fairfax County lists replacing a heating or cooling system as mechanical permit work. Source.
How to pick who works on your boiler in Clifton.
Questions to ask anybody who quotes you, us included.
Do they know the Town’s letter comes before the County permit?
Ask how they run a job inside the town line. An application filed with Fairfax County without the Town’s letter sits until someone uploads it, and the boiler waits with it.
Can they handle both halves of it?
A hot water boiler is half heating system (the burner, gas valve, flue and controls) and half plumbing (the water loop, circulator pumps, expansion tank, relief valve and zone valves). We hold a Virginia Class A license and run separate heating and plumbing teams, so each half gets a tech who does that trade every day.
Does the quote say how it vents?
A new boiler can stay on the chimney or vent out the wall in plastic pipe. A good quote says which, and whether the chimney needs a liner, because that’s where two quotes for the same boiler usually split.
What our customers say.
Replacement for my broken gas water boiler was professionally done and in a timely manner. The technicians knew exactly what they were doing.

Boiler questions from Clifton.
Can a house in the Clifton Historic District get a condensing boiler?
It can, but the wall vent it needs changes the outside of the house, which takes the Architectural Review Board’s certificate of appropriateness. A cast iron boiler that keeps the chimney leaves the outside alone, which is one reason it can be the simpler swap in town.
Is the old boiler in a Clifton house worth repairing?
If the heat exchanger and the cast iron sections are sound, yes: the circulator, the zone valves, the expansion tank and the relief valve are all repairs. When a section cracks or the exchanger leaks, the boiler is done, and the $99 diagnostic tells you which you have, in writing.
Do you work on steam or oil boilers?
No. We work on hot water boilers, the kind that heat radiators or baseboard, on natural gas or propane. If yours is steam or burns oil, we’ll tell you on the phone, and a switch to a heat pump or a gas or propane boiler is ours to price.
