A repair starts with the $99 diagnostic. If the fix is a circulator pump, a valve or an expansion tank, you get that price in writing before we start, and you decide.

What’s different in Fort Belvoir
ZIP 22060 counts 3,456 housing units, and about six in ten of them sit inside the Army post. Family housing there is privatized: The Villages at Belvoir runs it, and a resident puts in a broken boiler, like any other repair, as a service request with The Villages. Our boiler work in Fort Belvoir is the other four in ten, the homes with 22060 mail outside the installation, which are Fairfax County’s.
Only about 270 homes in the ZIP are owner-occupied, and nine in ten of its occupied homes are rented, so a boiler call off post often comes from a landlord or a property manager as much as from the family living there. Among owner homes, about four in five heat with gas and the rest with electricity, so a boiler here is almost certainly on natural gas.
Close to half of those owner homes are townhouses and about three in ten are condos, with detached houses at about one in four. In a townhouse or a condo the boiler usually shares a utility closet with the water heater, and the swap that fits is often a wall-hung Navien combi at $12,782 to $16,500 installed, which heats the radiators and makes the hot water from one box on the wall. In a condo, ask the association about a new wall vent before the quote is final.
Off post, a boiler swap is Fairfax County permit work even like for like, since the County wants a permit for any gas appliance replacement and a chimney vent certification for a fuel-burning one. When a boiler quits in the cold, Virginia’s code puts the work ahead of the paperwork, with the application due by the end of the next working day. The cold does come: Oxon Hill, the nearest long-record station across the Potomac, logs about 80 nights a year at or below freezing, and in late January 2026 wind chills from the Piedmont to I-95 fell to between 0 and -10.
What it’s telling you
With nine in ten homes in 22060 rented, the person who hears the boiler bang is often not the person who pays for it. A written diagnosis from the $99 visit, with the repair priced, gives the owner something to approve from a distance, which helps when the owner lives somewhere else.

Safety and paperwork
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.

Choosing who works on it
Questions to ask anybody who quotes you, us included.
Ask whether the quote can go to the owner or the property manager by email, with the part, the labor and the total spelled out, so a repair isn’t held up waiting on a signature in person.
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.
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.

Replacement for my broken gas water boiler was professionally done and in a timely manner. The technicians knew exactly what they were doing.

Questions
No. On-post family housing belongs to The Villages at Belvoir, owned and managed by The Michaels Organization since 2021, and its residents put repairs in as a service request with The Villages. We work on the boilers in the 22060 homes outside the post.
Fairfax County Fire and Rescue asks for a yearly heating check by a professional and a CO alarm on every floor. The $99 tune-up covers the first: burner, gas pressure, safeties and venting, before the closet boiler has to carry a January night.
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.
