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 Delaplane
Electricity is the main heat in about 30 percent of Delaplane’s owner homes, and in a rural detached house that usually means a heat pump with electric strips in the air handler. Propane heats more than half, and that’s the other place a heat pump fits here: on top of a propane furnace, in the air conditioner’s old spot, heating through the mild months and handing the hardest cold to the furnace.
A January afternoon at Warrenton 3 SE, the closest long-record station, averages about 42 degrees, which is comfortable work for a heat pump. The hard stretch is short: about 13 days a year that stay below freezing all day and about five nights at 10 or colder. On those a heat pump still heats, with less to give, and the strips or the propane furnace cover the rest. Fauquier County sizes heating to 17 degrees outside, so pick the backup against that.
Not all of 20144 sits at the village’s 449 feet. The ZIP runs up the valley to Sky Meadows State Park on the eastern face of the Blue Ridge, and the Mount Weather station on the ridge, at 1,659 feet, counts about 105 freezing nights a year to Warrenton’s 98, with its last spring freeze about a week later. A house up toward the ridge works its heat pump harder than one down by Goose Creek, so one size doesn’t fit both.
Plan around the power, too. Downed trees and wires caused an outage near Delaplane in September 2023, and in July 2025 a storm brought trees and wires down at Delaplane Grade Road and Carr Lane. A heat pump stops when the power does, and its strips are the heaviest load you can hand a generator. Tell us the generator’s size, and we’ll say what part of the new system it can carry.
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 20144 as a whole: every Delaplane address.
When it’s time
The village sits where Crooked Run meets Goose Creek, and FEMA maps a Zone A flood area within about 300 meters of its center. A heat pump whose base has stood in water rusts from the bottom up. If yours has, have it checked before it runs again, and set its replacement up on a stand.
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.
Most heat pumps installed before 2010 hold R-22, which hasn’t been made since 2020. A leak on one is usually where recharging stops making sense.
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.
In a propane house, ask for a heat pump beside the furnace you have and an all-electric heat pump with strips, each on paper. Which one wins depends on the furnace’s age and how the house holds heat.
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.

Questions
Most of it, easily. For the handful of days that stay below freezing it needs help, from strips in an all-electric house or from the propane furnace in a dual fuel one. A cold-climate model narrows that gap, and a house high on the slope toward the ridge is where it earns its keep.
$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.
