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 Midland
Of the 1,066 owner homes in ZIP 22728, the Census counts 354 heating with propane, 622 with electricity and 12 with utility gas. So a hot water boiler in Midland burns propane from a tank on the property, and the tank, as much as the boiler, decides whether the house has heat on a January morning.
Midland sits in the Piedmont’s Culpeper Basin, on what the County calls a former lakebed shared with Bealeton, Opal and Remington. There’s no public sewer, and no public water beyond a limited supply for the airport, so homes run on wells and septic. About one in five owner homes predates 1960 and close to half predate 1980, with the typical one dating from 1986.
A propane boiler replacement in Midland is permit work even in the same spot, since Fauquier County counts any fuel-fired appliance. It’s a trade permit, issued in Warrenton by the Department of Community Development, and it needs no drawings. Heat here is sized for 17 degrees outside, the County’s design temperature, and the January average low at the Warrenton 3 SE station is 24.8, with about 98 nights a year at or below freezing.
Wind is Midland’s measured hazard. The airport’s weather station recorded a 74 mph gust in August 2021 that uprooted trees several feet thick near Midland Road and Airport Road, and in 2011 an EF0 tornado along Rogues Road and Midland Road tore the metal roof off a farmhouse. A propane boiler goes cold without power, so after a storm, check that the radiators warm up again once the lights come back.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
ZIP 22728 as a whole: every Midland address, the village included. The Census place for the village alone has too few homes for steady figures.
What it’s telling you
A condensing boiler drains acidic water as it runs, and in a Midland house on septic that water ends up in the tank and the drain field. A neutralizer cartridge on the condensate line raises its pH before it leaves the boiler, and it’s a small part worth asking for on the quote.

Safety and paperwork
Outside the town limits, Fauquier County issues the permit. It wants one for any fuel-fired water heater, propane included, and for any heater being moved; an electric one swapped for a similar unit in the same spot counts as an ordinary repair. Trade permits go out over the counter the day the application comes in. Source.

Choosing who works on it
Questions to ask anybody who quotes you, us included.
A new boiler usually ships set for natural gas. Ask that the quote name the propane conversion and the leak check before first fire, so it’s plain the boiler leaves set for the fuel in your tank.
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.

…I had the pleasure of working with Efrain and Alex last year on a Boiler heater. The quality of work and total professionalism contributed 100% to my decision…
Questions
Yes. A repair begins with the $99 diagnostic and a written price, and replacing the boiler outright is $9,900 to $16,500 installed.
Ducts decide it. Electricity heats close to six in ten owner homes here, mostly with heat pumps, so it’s a familiar choice; a house built around radiators or baseboard is usually better served by a new boiler. We can price both side by side.
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.
