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 Aldie
Electricity heats about 15 percent of Aldie’s owner homes, and the Census counts a heat pump as electric heat, so that’s roughly the share running on one alone. Stone Ridge sits lower, near 11 percent, which puts the streets outside it above the ZIP’s figure. In a house built since 2000 that’s usually a heat pump with an air handler and backup strips.
Gas heats most of the rest, and in a gas house a heat pump goes in beside the furnace, not instead of it, on the pad where the air conditioner sat. Washington Gas pays a dual fuel rebate for that exact swap, with the terms in the questions below. Stone Ridge’s design standards group air conditioners and heat pumps together, and replacing an approved one where it sits needs no application.
Whether your electric bill comes from Dominion Energy or NOVEC changes where that handoff belongs. Stone Ridge’s association lists both. NOVEC’s winter electricity costs less, so on NOVEC the heat pump can carry the house into much colder weather before gas becomes the cheaper heat; on Dominion the furnace takes over sooner. Our dual fuel guide works out both, and the thermostat gets set for the company on your bill.
About one owner home in twenty burns propane, and a heat pump pairs with a propane furnace the same way, covering spring and fall and leaving January to the furnace. In the condo buildings, Centre Park and Stone Springs among them, the heat is often a heat pump alone, its air handler in a closet and its outdoor unit wherever the association placed it.
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 20105 as a whole: every Aldie address, inside Stone Ridge and out.
When it’s time
Frost on a heat pump’s outdoor coil in winter is normal, and the defrost cycle clears it. A unit that stays encased in ice has a defrost or refrigerant fault. On a young Aldie heat pump that’s a repair, found on a $99 diagnostic visit; on a 2000s original, ask for the replacement range beside it.
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.
A heat pump from a 2000s house that’s still original has run every summer and winter since. Once repairs start, price the replacement before the next one.
Choosing who installs it
Questions to ask anybody who quotes you, us included.
Dominion or NOVEC moves the temperature where a dual fuel system should hand the heating to the furnace. An installer who sets that switchover without asking is guessing.
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.

I would highly recommend SwiftPro for an HVAC replacement. The sales process was straightforward and fair and the installation was done to my satisfaction in a timely and complete manner (and I’m pretty demanding). Great job!

Questions
It can, if the house is on Washington Gas and the heat pump replaces a central air conditioner; swapping one heat pump for another doesn’t qualify. The heat pump and the furnace both have efficiency minimums, and a contractor on Washington Gas’s participating list files it. A propane house, off its lines, prices the job without it.
Another heat pump system, the outdoor unit plus the air handler and its backup strips, sized to the house rather than the old nameplate. In a house built since 2000 the ducts were laid out for that system, so they usually carry over as they are. The HVAC estimator narrows the range to yours.
$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.
