What’s different in Calverton
Electric heat leads around Calverton. The Census counts 526 of the 1,040 owner homes in Catlett’s ZIP, 20119, heating with electricity, and 622 of 1,066 in Midland’s 22728, the two ZIPs Calverton’s street addresses carry. With almost no natural gas heat in either, that mostly means a heat pump, with electric strips in the air handler for backup.
Winter is the real test. The NOAA normals station at Warrenton 3 SE, about six miles away, counts close to 100 nights a year at or below freezing and about 5 at or below 10 degrees, and it bottomed out at 3 degrees in January 2014. Fauquier County’s code table sets 17 degrees as the design temperature, the number to size against. The January 2026 Arctic outbreak brought Piedmont wind chills of 0 to minus 10, but wind chill measures skin; a heat pump only feels the air.
About three owner homes in ten in 20119 heat with propane, and in plenty of those the heat pump’s coil sits on a propane furnace instead of in an air handler. When the heat pump goes, the furnace usually stays: the new outdoor unit gets matched to that coil, and the temperature where the furnace takes over is set again, so propane burns only when the heat pump can’t keep up.
Where the outdoor unit sits matters here. Warrenton 3 SE had 25 inches of snow on the ground after the January 2016 blizzard, and the December 2020 ice storm left up to half an inch of ice at Opal, in the same forecast zone. A heat pump melts its own frost to keep heating, so the new one belongs on a stand above the drifts where meltwater runs off, and in the village, above where floodwater reaches.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise. A heat pump counts as electric heat.
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.
When it’s time
Some frost on the coil is normal, and the defrost cycle clears it. A unit that stays solid ice, especially after an ice storm, means the defrost or the airflow has failed. Switch to emergency heat and book the $99 diagnostic.
When the heat pump can’t keep up, the electric strips take over, and they cost far more to run. Aux heat on for hours is the sign.
It heats all winter and cools all summer, so it piles up hours an air conditioner never sees. Past 15 years, price the replacement beside any big repair.
Permits, locally
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.

Choosing who installs it
Questions to ask anybody who quotes you, us included.
Ask at what outdoor temperature the new heat pump stops carrying the house alone. Sized right for Calverton, it should hold most freezing nights alone. If nobody can answer, the strips or the propane will be doing your winter.
Copying the old nameplate repeats whatever guess was made when the house was built. The wrong size runs worse in both seasons.
A heat pump system is the outdoor unit plus the air handler inside. Ask whether the quote covers both, matched, in writing.
Set wrong, the electric strips run on mild days. Ask who programs the thermostat and at what outdoor temperature the strips may come on.

Excellent work by Tyler and Team. Right from pricing to performing professional installation of new Heat Pump.
Questions
It can. More than half of the historic district’s buildings went up between 1920 and 1960, and any ductwork came later. A heat pump moves more air at a lower temperature than a furnace, so small ducts get checked first; with none, ductless is the other road.
It stops, and so do the strips; a propane furnace stops too, since its blower and controls need electricity. When power returns, give it a few minutes; many heat pumps wait out a delay before restarting. If it still won’t run, or a limb hit the outdoor unit, call us after the storm and we’ll check it all.
$8,499 to $21,650 installed for a heat pump system, the outdoor unit and the air handler, 2 to 5 ton. A small single-stage system lands near the bottom, a big variable-speed one near the top. The HVAC estimator narrows it to your house.
A heat pump system runs $8,499 to $21,650 installed; a gas furnace and air conditioner together, $8,898 to $23,000. No gas line usually means a heat pump. With gas, you can keep the furnace and add one; our heat pump vs gas furnace guide runs the numbers.
