Purcellville heats with heat pumps and propane; natural gas is the rare one.
Inside the Town of Purcellville, the Census counts about half the homeowners heating with electricity, about a third with propane, and only about one in twenty with natural gas. Step outside the town limits and propane rises to close to half. So a no-heat call here is seldom the natural gas furnace common closer in. It’s usually a heat pump, or a furnace fed from a tank in the yard.
A propane furnace is built like a natural gas one, with the same igniter, flame sensor and pressure switch, but its gas valve and burner orifices are set up for propane’s higher pressure. The difference that matters on a cold night is the supply. If the tank ran dry, call your propane company before you call us, because after a run-out the system should be leak-checked before anything relights. If the tank is full and the furnace still won’t fire, that one’s ours.
Plenty of houses here pair the two: a heat pump carries most of the winter, and a propane furnace takes over on the hardest nights. When one half of that pair finally wears out, the real question is what comes next, and the paperwork differs by fuel. A propane furnace takes a Loudoun County permit even like for like; a heat pump swapped in place goes without one.
The age question splits at the town line. The town’s median owner home dates to 2001, so a furnace or heat pump that came with it is about twenty-five, the age where a big repair deserves a replacement price next to it. On the county side close to three in ten homes are older than 1980, and a house that old may have changed heat along the way, a propane furnace swapped in, or a heat pump added with the furnace kept as backup.

What a failing furnace in Purcellville usually does.
The tank gauge is low and the heat quit
On propane, read the gauge on the tank before anything else. If it’s near empty, call for a delivery first. Once it’s refilled and the supplier has checked the system, a furnace that still won’t light is a repair visit.
The heat pump blows cool air
A few minutes of cool air in winter is a defrost cycle, and that’s normal. Cool air all the time, or emergency heat running all day, is a call.
It smells the first time it runs
Dust burning off the heat exchanger smells for the first few minutes of the season, then stops. A gas smell is different: leave the house and call your gas company from outside.

Questions worth asking anybody who comes out, us included.
Do they work on propane furnaces, not only natural gas?
We do propane and natural gas furnaces; oil burners we don’t work on. In 20132 most furnaces that burn gas burn propane, so ask whether the tech checks the gas pressure at the valve against the propane setting, not the natural gas one, because a furnace set up for the wrong fuel doesn’t burn right.
Will they price the part before they fix it?
Flame sensors, igniters and control boards all have a going rate. A tech who can’t tell you the number before starting is asking you to find out afterwards.
Do they look at the venting, not just the flame?
Getting the burners lit is half a heating call. Ask whether they check the flue and test for carbon monoxide while the panel’s open.
Do they know when a repair isn’t worth it?
A big repair on a furnace past 15 or 20 years deserves a replacement price next to it. A good tech puts both numbers in front of you and lets you choose.

Heating repair questions from Purcellville.
Can a natural gas furnace run on propane?
Only after it’s converted. Propane runs at a higher pressure, so the gas valve gets a different spring and the burners get smaller orifices, usually from a kit the manufacturer makes for that model, and the job ends with a pressure and combustion check. A furnace connected to the other fuel without that conversion is unsafe, not just inefficient.
Does Loudoun County want a permit for a new propane furnace?
Yes, inside the town and out. Virginia’s code lets an appliance be swapped without a permit only when it doesn’t burn gas or oil, and propane is a gas. Loudoun County issues building permits across the whole county, towns included, and since October 2025 a replacement at the same BTUs in the same spot needs no plans.
How much does furnace repair cost in Purcellville?
The diagnostic visit is $99. A flame sensor cleaned is $95 to $180; an igniter or flame sensor replaced, $240 to $410; a control board, $550 to $1,180; a blower motor, $670 to $2,400.
Should I repair it or replace it?
Fix the small parts on almost anything. Before a big repair on an old furnace, look at the replacement number: a furnace alone, keeping the air conditioner you have, runs $4,285 to $14,040 installed, and the HVAC estimator gives your number in about a minute.
