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 Clifton
Electricity heats Clifton unevenly. In the Census tract that takes in the town and the big lots along Clifton, Compton and Yates Ford Roads, 676 of 1,293 owner homes heat with it, a bit over half, against about a third across Fairfax County. Off Springstone Drive it’s closer to one in seven. The Census counts a heat pump as electric heat, so on the acreage the usual job is a heat pump for a heat pump: outdoor unit and air handler, with electric strips inside for backup.
Those houses date from the late 1980s; the tract’s median owner home was built in 1987. A heat pump works every season, so the one outside now is very likely not the first the house has had, and if it went in before 2010 the label on its side most likely says R-22. Read that label before paying for a recharge, because a leak in one of those is usually where fixing it stops making sense.
Rebates are thin out here. Fairfax County’s map puts nearly all of Clifton on NOVEC, and NOVEC offers no heat pump rebate; Dominion’s heat pump rebates are for Dominion customers. Washington Gas pays toward a dual fuel heat pump, but only for its own gas customers, only when the heat pump takes an air conditioner’s place, and never when it replaces another heat pump. For a NOVEC house swapping heat pump for heat pump, plan on no utility rebate behind it.
Where the house burns propane, there’s a middle road. About one owner home in ten in that tract does, and a heat pump paired with a propane furnace runs on electricity through the mild weather and lets the burner take over when it turns truly cold. The furnace stays, and the heat pump takes the air conditioner’s spot outside.
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.
Clifton mail outside the town: five- to ten-acre lots in the Occoquan watershed on Clifton, Compton and Yates Ford Roads, mostly on septic, and the 1980s subdivisions off Springstone Drive and Union Mill Road on county sewer.
ZIP 20124 as a whole, the Town included: its own homes are too few for steady Census figures.
When it’s time
NOVEC’s own advice is to use Emergency Heat only when the heat pump itself has failed, because it runs the house on the electric strips alone. If yours has been set there for weeks because the outdoor unit can’t keep up, price the replacement beside the repair. The diagnostic visit is $99.
A heat pump can go where the air conditioner sat, heat on mild days and leave the cold nights to the furnace. That’s dual fuel.
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.

Choosing who installs it
Questions to ask anybody who quotes you, us included.
In Clifton it’s NOVEC for nearly everyone, and that changes which rebates exist and where a dual fuel system should hand off to the furnace. Our dual fuel guide works that switch point out for NOVEC and Dominion houses separately.
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
Its sign-off, yes. Fairfax County issues the mechanical permit, with an A2L refrigeration certification for a unit on the newer refrigerants, but it won’t take the application for a house inside the town line until the Town has signed off by letter. A new outdoor unit in a new spot also needs the Architectural Review Board’s certificate.
$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.
