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
Might it be a repair? The diagnostic visit is $99, and the tech prices the repair and the replacement side by side. Financing is available, subject to approval.
With Comfort+ membership at $199 a year, the diagnostic visit is included, and half of each repair bill is banked toward replacing that system, up to $1,500.
What’s different in Marshall
The Census never asks about heat pumps by name; it counts them as electric heat. In 20115 that’s 1,357 of the 2,109 owner homes, and 647 of the 849 rented ones, about three in four. With natural gas heating 8 owner homes in the whole ZIP, a heat pump here isn’t the alternative to a furnace; for most houses it is the heat. A replacement swaps both halves, the unit outside and the air handler with its backup strips, and keeps the ducts.
About one owner home in five burns propane, and in plenty of those the heat pump’s indoor coil sits on the furnace, which takes over on the coldest nights. Replacing that heat pump leaves the furnace in place; what gets redone is the handoff temperature in the thermostat, set for what the new outdoor unit can carry rather than copied from the old one’s settings.
Wood is the main heat in 160 owner homes, about one in thirteen, and in some of them the heat pump mostly cools. Sizing from the old nameplate misses twice in a house like that: the heat pump may only need to cover spring, fall and the rooms the stove never reaches, or it may have to carry the whole house the week nobody’s home to feed the stove. Say which when you book.
The old village is the hard case. An I-house on Main Street or a story-and-a-half frame house on Anderson Avenue went up long before central air, and its ducts were often threaded in later, wherever they’d fit. A heat pump moves more air than a furnace, at a gentler temperature, so we measure those runs before quoting; a cramped retrofit duct is often why the upstairs never warmed up.
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.
ZIP 20115 as a whole: every Marshall address, the village included. The Census place for the village alone has too few homes for steady figures.
When it’s time
About three rented homes in four in 20115 heat with electricity. A heat pump that needs topping up every season is leaking, and each top-off only buys months. For a landlord, a replacement priced in October beats a tenant’s no-heat call in January; the $99 diagnostic visit prices both.
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.
On Marshall’s open lots, wind piles snow against whatever stands in its way, and a heat pump sheds meltwater every time it defrosts. Ask whether the new one goes on a raised stand or pad, clear of roof runoff and drifts.
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 price and service. Had our AC/heating system replaced. Gave us a great price and top quality install. Can’t say enough good things about them.

Questions
Yes, where the ducts can carry its air. Where they can’t, say a bedroom under the roof of a story-and-a-half house, a ductless head can take that room while the central heat pump does the rest. The HVAC estimator gives the range for the central system.
Yes, anywhere with a 20115 address, from the same price book as Main Street. A farmhouse panel may also run the well pump and an outbuilding, so the tech checks that the backup strips will have the circuit they need.
$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.
