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 Upperville
ZIP 20184 counts just 67 owner homes, and about seven in ten were built before 1960. None heats with utility gas; electricity heats about two in three and propane the rest, so an Upperville boiler burns propane from a tank on the property. The owner homes here are all detached houses. About seven in ten homes here are rented, so the call often comes from a tenant while the repair decision rests with the owner.
In a house that old the boiler often sits in a tight cellar or crawlspace. A wall-hung condensing boiler, at $12,782 to $16,500 installed, can fit a cramped cellar better than a large floor-standing one, but it changes the exhaust path from the chimney to a wall, and in an old wall that opening needs care. Houses this old predate central heat, so their radiators and piping were added later. None of the owner homes in the Census count went up after 1999, so an Upperville boiler sits in an older house by definition.
Upperville straddles the county line. On the Fauquier side, the County issues permits for fuel-fired appliances, a propane boiler included, from its office in Warrenton. Loudoun’s rule since October 2025 skips submitted plans for a same-BTU replacement in the same location. Which county your address is in decides which rule applies.
Purcellville’s weather station, about 14 miles away, shows January lows around 24.5 degrees and roughly 115 freezing nights a year, and Fauquier County sizes heating for a 17 degree day. Weeks of that wear on the circulator and the expansion tank first, which is what a fall tune-up checks. A boiler that sits idle all summer in a cold cellar can also seize its circulator, and the fall start-up is when that shows.
What it’s telling you
A boiler in a cold, cramped cellar works harder and hides its leaks. A drip near the base or rust on the jacket is worth a look before winter, not after the first cold night. Cellar damp also rusts the burner.

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.
Fauquier County counts swapping an electric appliance for a similar one in the same spot as an ordinary repair that needs no permit. Moving an appliance to a new spot takes one. Source.
Fauquier County Fire Rescue takes requests for help getting smoke and carbon monoxide alarms through a form on its Public Education page. Source.
Loudoun County requires a permit to swap a gas water heater or furnace. Since October 2025, a replacement that keeps the same BTUs in the same spot needs no plans. Source.
In its fall clock-change reminder, Loudoun County’s fire and rescue system tells residents to check their carbon monoxide alarms, and recommends one outside each sleeping area and on each level of the home, tested monthly. Source.
Loudoun County Fire and Rescue says to have heating equipment and chimneys cleaned and inspected every year by a qualified professional, and to keep anything that can burn at least three feet from all heating equipment. Source.

Choosing who works on it
Questions to ask anybody who quotes you, us included.
Upperville addresses can fall in Fauquier or Loudoun. Ask the installer which permit office applies before the quote is written. The answer also decides which county inspects the work.
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
Usually: a wall-hung unit leaves the floor clear in a tight cellar. The real question is where its plastic vent exits, and the written price answers it.
Look at the heat exchanger first. A sound one makes a pump, valve or tank failure worth repairing; a leaking one ends the boiler, and the $99 diagnostic shows which you have.
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.
