Falls Church is one of our two boiler towns, and the City line decides the permit.
Falls Church is one of the two places, with McLean, where boilers are a regular part of our heating work. The housing explains it. In the City of Falls Church the typical owner home dates from 1964 and about one in three predates 1960; on the Fairfax County side, in the Idylwood count, the typical one is from 1975, with about three in ten older than 1960. Those are the decades a hot water boiler with radiators or baseboard was still a common way to heat a new house.
A Falls Church mailing address reaches far past the City limits: Merrifield, Seven Corners and Bailey’s Crossroads are Fairfax County. Inside the City, the permit counter is at City Hall, 300 Park Avenue, and any work on a natural gas appliance takes a gas permit, removing one included. On the County side, a gas boiler replacement needs a Fairfax County permit even like for like, plus a chimney vent certification.
Condos are a big share here, about four in ten owner homes on the County side and close to half in the City. A condo boiler can belong to the building rather than the unit, so check with the association before calling anyone. When it’s yours, it’s usually a closet unit, and a wall-hung Navien combi at $12,782 to $16,500 installed can replace the boiler and the water heater in one box.
Gas heats about seven in ten owner homes in the City and about six in ten on the County side, so a Falls Church boiler is most likely on natural gas. One from the 1960s usually vents up a masonry chimney, and the choice at replacement is whether to keep that chimney with a new cast iron boiler or move to a condensing boiler that vents through a side wall in plastic pipe. City residents can also book a home safety check from the Arlington County Fire Department.

- Houses this age are where the boilers are: cast iron, often venting up a chimney shared with the water heater. When one gets replaced, the chimney may need a liner, and that goes in the written price.
- In condo buildings the boiler in the basement usually belongs to the association, not you. Check your documents; if your unit’s heat is yours, book it like any house.

- Most homes here heat with gas, so a boiler tune-up here starts with the gas pressure and the flame.

What your boiler is telling you in Falls Church.
The pressure gauge keeps creeping down
A boiler that needs topping up every week is losing water somewhere: a weeping valve, a fitting on an old radiator, or the relief valve letting go. The fresh water that replaces it carries oxygen into the loop, and oxygen rusts cast iron from the inside, so a slow leak is worth finding in October rather than living with.
What the county says about boilers in Falls Church.
City of Falls Church
The City of Falls Church wants a gas permit for any work on a natural gas appliance, taking one out included, so a gas water heater swap is permit work even like for like. Rewiring for an electric one takes an electrical permit. Source.
In a single-family house in the City of Falls Church, an air conditioner or heat pump can be replaced without a permit. Source.
The Arlington County Fire Department, which offers home safety checks to City of Falls Church residents, asks on its home checklist whether a forced-air furnace’s filter is changed yearly and its venting cleaned, and whether the furnace sits clear of combustible walls and ceilings. Source.
Fairfax County
Fairfax County requires a permit to replace any gas appliance, even like for like: a gas water heater, furnace or boiler. Replacing a fuel-burning appliance also needs a chimney vent certification. Source.
Fairfax County lists replacing a heating or cooling system as mechanical permit work. Source.
Fairfax County Fire and Rescue names a faulty gas furnace or water heater as a carbon monoxide source, says to have gas appliances inspected every fall, and to put a CO alarm on every floor. Source.
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.
How to pick who works on your boiler in Falls Church.
Questions to ask anybody who quotes you, us included.
Did they ask whether the house is in the City or the County?
A quote for a Falls Church boiler that never asks which side of the City line you’re on is guessing at the permit, and the City and the County each want their own.
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.
…excellent service when my boiler needed to be replaced during the polar vortex. Alex Hittle came quickly, … and replaced my boiler quickly. Alex even managed to change their schedule, with the kind permission of their other customer so that I could have heat again in the freezing weather.

Boiler questions from Falls Church.
Do you work on the older boilers in Pimmit Hills and Lake Barcroft?
Yes. Pimmit Hills, where half the owner homes were up by 1961, and Lake Barcroft are among the older Falls Church neighborhoods, the kind where a gas boiler is likeliest. Fixing one begins with the $99 diagnostic.
Can I replace a Falls Church boiler with a heat pump?
With ducts already in for the air conditioning, a heat pump is a real option, and we’ll price it beside a new boiler. Without ducts, keeping the radiators and replacing the boiler is usually the simpler job.
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.
