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 Springfield
The median owner home in Springfield went up in 1968, and close to six in ten were built before 1980. Those houses often came with forced air, but the boilers are the ones that stayed. They sit in basements or utility rooms, usually on gas, since about six in ten owners here heat with it. In the newer sections like Newington, boilers are rare because most owners heat with electricity. But in the older parts, a hot water loop is common, and when it fails, it is usually the parts around the boiler that give out first.
A boiler that runs for decades wears down its circulator pump, zone valves, and expansion tank before the heat exchanger itself fails. These are repairs, not replacements. The $99 diagnostic finds which part is tired. If the pressure gauge is drifting or the relief valve drips, it points to the expansion tank or fill valve. If the radiators are cold at the top, it is likely air in the loop. Each of these gets a written price after the diagnostic, before any work starts.
Replacing a boiler in Fairfax County means a permit for the gas appliance swap, even if it is like for like. If the old unit vented up a flue, a chimney vent certification is also required. A cast iron boiler can often stay on that existing chimney, keeping the job in the lower range of $9,900 to $16,500. A condensing boiler pipes its exhaust through the nearest outside wall in PVC and sends its condensate to a floor drain or a small pump, landing at $12,782 to $16,500. Your quote should specify which venting path you are taking and what the water heater will need if it shares that flue.
Springfield has about three in ten townhouses, and in those homes the boiler often shares a tight space with the water heater. A wall-hung combi can clear that floor space, but it only works if your hot water needs are modest. For a larger house with several showers, a heat-only boiler with a separate tank is usually the better fit. The $99 tune-up in the fall checks the burner, the flame, the gas pressure, and the system pressure, and it is the best time to catch small issues before they become big ones.

What it’s telling you
A dripping relief valve means the pressure in the loop is near 30 psi. It is usually the expansion tank or the fill valve that has failed. It is a repair, not a replacement, and the $99 diagnostic will name the part and give you a written price before anyone drains the system.

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.
Yes, and they should. Those two parts fail more often than the boiler itself in a Springfield house from the 1960s or 70s. If the tech only looks at the burner, ask why the pressure is drifting. The answer should be specific, not a guess.
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.

…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.

Questions
Yes. Fairfax County wants a permit for any gas appliance replacement, including boilers. If the old unit vented up a flue, you also need a chimney vent certification. If it is an emergency, the work can start first, but the application must be in by the end of the next working day.
Yes, a heat pump is a valid switch. We can price that installation for you. It changes the permit path from a gas appliance swap to a mechanical permit for the new unit. The quote covers the new equipment and removing the old boiler.
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.
Ready when you are
Call any time: we run 24/7 emergency service. Or send the form at the top. A tune-up is $99, a repair starts with the $99 diagnostic, and a new boiler gets a written price before any work.
