Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
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 Fredericksburg
On this side of the Rappahannock, a Fredericksburg address in 22405 or 22406 is Stafford County, not the City. The two ZIPs hold 18,193 owner homes, the typical one from 1999, and close to half went up since 2000. About one in four predates 1980, and a hot water boiler in 22405 or 22406 most often belongs to that older quarter.
Across both ZIPs, electricity heats close to half the owner homes and natural gas about four in ten, with propane under one in ten. A Fredericksburg boiler is most likely on a gas line, and a propane one gets checked against propane’s pressure at the tune-up. Falmouth sits at 59 feet on the river’s north bank, and the land rises west into rolling country.
A gas boiler swap in Stafford needs a permit, filed as an appliance permit on the County’s Residential Change Building Permit Application at 1300 Courthouse Road. A boiler that dies on a January night doesn’t have to wait for the County: under the state code the replacement starts, and the application follows by the end of the next working day.
The nearest NOAA station sits on the Rappahannock at 60 feet, 5.2 miles south-southeast, and its 1991 to 2020 normals give a January low of 25 degrees and about 4,300 heating degree days, colder at night than Quantico up the Potomac. Storms add to it: on April 19, 2013, gusts estimated at 56 knots destroyed the second floor of a house near Forbes Street and Falmouth Drive, and the January 3-4, 2022 storm reached 14.6 inches in places.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIPs 22405 and 22406 as a whole: Fredericksburg mail on the Stafford County side, not the City of Fredericksburg.
What it’s telling you
Tap the expansion tank by the boiler: one that sounds solid all the way up has lost its air cushion, and without it the pressure climbs every time the boiler heats until the relief valve lets water go. A new tank fixes it, and the $99 diagnostic confirms that’s the cause.

Choosing who works on it
Questions to ask anybody who quotes you, us included.
On a boiler the age of the house, ask for both numbers in writing. A repair that’s a fraction of the $9,900 to $16,500 installed price of a new one is usually worth making while the heat exchanger holds.
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
On the Stafford County side, yes: Falmouth, Ferry Farm and the rest of 22405 and 22406. Boiler tune-ups there are $99, and a high-efficiency or combi replacement comes to $12,782 to $16,500 installed.
A combi can: a wall-hung Navien heats the radiators and makes hot water on demand, replacing both the boiler and the water heater. It fits best where the hot water demand is modest, and it vents through the wall in plastic pipe.
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.
