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 Arlington
About six in ten Arlington homeowners heat with gas, and the median owner-occupied home was built in 1960. In neighborhoods like Maywood, Lyon Park and Cherrydale, that means a boiler often sits in a basement that has outlived several heating systems, venting into a chimney older than the boiler itself. When one fails here, it’s rarely the first boiler in that spot, and the new one has to fit piping and a flue that have survived every swap before it.
We do more work through landlords and property managers in Arlington than in almost any other town, so condo buildings, tenant scheduling and access rules are routine for us there. Close to six in ten Arlington homes are rented, so check who owns the boiler before you book: in a rental house it’s usually the landlord’s, and in a condo building the boiler in the basement usually belongs to the association. The Arlington County Fire Department recommends a yearly inspection of furnaces, flues and chimneys by a trained professional, and on a boiler that’s the $99 tune-up: the combustion, the venting and the safeties that shut it down if the flue backs up.
Arlington County requires a plumbing and gas permit with inspections to replace anything fueled by gas, including a boiler. This applies even if you are swapping in the same type, size, and location. The County strongly suggests the contractor doing the work holds the permit. An owner can hold a residential permit for only one address in two years, which limits how a landlord can handle paperwork across multiple units. If a boiler fails and you need an emergency replacement, Virginia law allows the work to start before the paperwork is filed, as long as the permit application reaches the County by the end of the next working day.
About one in four owner homes in Arlington is a detached house, and more than half are condos and apartments, so the boilers we work on here are mostly in the older detached houses and rowhouses. About one in a hundred owner homes still heat with oil; we don’t work on oil boilers, and a switch to a gas boiler or a heat pump is ours to price.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
What it’s telling you
In Arlington’s older homes, the chimney or flue was there before the boiler was installed. A new boiler may vent differently than the old one, and the connection between the two can be a weak point. A tech who checks the venting with the burners lit can spot a blockage or a gap that a visual inspection misses.

Safety and paperwork
Arlington County wants a plumbing and gas permit, with inspections, to replace anything fueled by gas, a gas water heater included. Off gas, swapping in the same type, size and location needs no permit. Source.
Replacing a furnace or air conditioner with the same type, size and location needs no Arlington permit unless it burns gas, which takes a plumbing and gas permit. With no permit, Zoning still approves where any outdoor equipment goes. Source.
The same page names gas furnaces and water heaters among the appliances carbon monoxide can escape from, and asks for at least one CO alarm near where people sleep. Source.
The Arlington County Fire Department says to have a trained professional inspect, clean and tune up furnaces, flues and chimneys every year, and to fix any leaks. Source.

Choosing who works on it
Questions to ask anybody who quotes you, us included.
In a house where the chimney is decades older than the boiler, a flue that drafts fine cold can spill when the burner’s lit. Ask whether the tech checks the venting with the boiler firing, not just by looking.
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.

…did a great job recommending a new system for a Condo that did not previously have one at all (Old Boiler System). The installation went great.

Questions
Yes. Arlington County requires a plumbing and gas permit with inspections for any gas-fueled equipment replacement, even a same-size swap in the same location. The County strongly suggests the contractor holds the permit. An owner can hold a residential permit for only one address in two years, so if you manage multiple units, the contractor should handle the paperwork.
Usually that boiler is the association’s, not yours, so the building’s manager books its service. If your unit has its own boiler and the heat is yours to keep up, book it like any house.
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.
