Calverton winters run on electricity and propane, with frost nearly a hundred nights a year.
Zero. That’s how many owner homes the Census finds on utility gas in 20119, the Catlett ZIP area where most Calverton houses sit. Roughly half run on electricity, which in a detached house here usually means a heat pump backed by resistance coils, and about 29 percent on propane brought in by truck. So a no-heat call here tends to be a compressor losing ground to the cold, or a propane burner that quits.
The long season is winter. Warrenton 3 SE, the closest NOAA normals station at six miles west-northwest, averages a 24.8 degree January low and logs around 98 frosty nights and some 4,685 heating degree days a year. Fauquier’s building design criteria pick 17 degrees as the design night, and on anything colder a heat pump sized to that number calls its backup coils in. That station has gone well below it: 3 degrees on January 7, 2014.
Snow causes plenty of January calls. The 2016 blizzard left 25 inches lying at that station. Drifted in up to its coil, a heat pump can’t draw air, and a condensing propane furnace that vents out a side wall through two plastic pipes locks itself off once snow covers them. After a big storm, shovel clear around the outdoor unit, uncover those pipes, and clear a route to the propane tank’s gauge.
Both kinds of Calverton heat stop when the power does: the propane furnace’s igniter, controls and blower are all electric. In December 2020 freezing rain glazed Opal, in the same southern Fauquier forecast zone, with as much as half an inch, and the Arctic air of late January 2026 pushed Piedmont wind chills to between zero and ten below. Once the power’s restored, if the house stays cold, flip the furnace’s service switch and look at the breakers one time, then phone us.
Calverton houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Calverton
Calverton’s own ZIP, 20138, is post office boxes only, so the Census Bureau maps no area for it. These are ZIP 20119 as a whole, the Catlett ZIP area that holds nearly nine in ten of the Calverton Census place’s homes.
- Median home built1990 Census
- Built before 1980about 4 in 10 Census
- Built since 2000about 2 in 10 Census
- Most homes aresingle-family houses, nearly all Census
- Heated withelectricity, about 5 in 10 Census
- Rentedabout 2 in 10 Census
- Electric heat here usually means a heat pump with electric strips as backup, and a heat pump stuck on those strips shows up on the electric bill.
- A few houses still burn heating oil. We don’t work on oil burners, but a switch to a heat pump or a gas or propane furnace is ours to price.

What a failing furnace in Calverton usually does.
Ice that never melts off the heat pump
On a damp 30 degree morning, white frost on the outdoor coil is normal, and the unit melts it off every so often, steaming as it goes. A coil locked inside solid ice, or ice piling on top from a dripping gutter, is not. Set the thermostat to emergency heat so the backup coils carry the load, and call.
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.

How to pick the best furnace repair company in Calverton.
Questions worth asking anybody who comes out, us included.
Will they check the tank before they price furnace parts?
When a propane furnace won’t fire, the cause can be an igniter, a flame sensor or a control board, or just a tank that’s run low. A good tech looks at the tank gauge first and sends you to your propane supplier when that’s the fault, instead of selling you a part.
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 Calverton.
My heat pump never shuts off on a 10 degree Calverton night. Is something wrong?
Probably not. Below the 17 degree night the County’s design criteria plan for, most heat pumps run without stopping and bring in the electric strips to help. Running nonstop at 45 degrees is a different story, and so is a house that won’t hold its temperature with the strips on. That’s a repair, and the diagnostic visit is $99.
How much does furnace repair cost in Calverton?
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.
