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 Ashburn
The Census counts a heat pump as electric heat, and across Ashburn about one owner home in six heats that way. About a third of Moorefield’s owners heat with electricity, and about a quarter in One Loudoun and Goose Creek Village, neighborhoods whose typical owner home dates from 2014 or 2015. Broadlands and Belmont, from the mid 2000s, are the least electric, at about one owner in twelve and one in ten.
Those newest heat pumps are about ten years old, and Moorefield and Goose Creek Village are each more than six in ten townhouses. At ten, most want a repair: a failed capacitor, fan motor or defrost board starts with a $99 diagnostic visit and a repair price, and you’ll hear that before anybody brings up a new system.
Ashburn Farm and Ashburn Village are the likelier place for one to be due. About 17 percent of owners in the Ashburn CDP heat with electricity, in houses whose typical owner home dates to 1998, so the heat pump there now is often a second one from the 2000s, old enough that a big repair deserves a replacement price beside it. University Center is the same age, but mostly condo and small apartment buildings with seven homes in ten rented, so the owner signs off and the association decides where the outdoor unit sits.
Brambleton’s design guidelines treat air conditioners and heat pumps in one section, and a unit replaced on its original pad or brackets needs no application. So in a Brambleton gas house, trading the old air conditioner for a heat pump on the same pad is the simple version, and the furnace stays inside for the coldest nights.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and what that usually means for a heat pump.
| Place | Median home built | Most homes are | Heated with | What a heat pump job usually looks like |
|---|---|---|---|---|
| Ashburn | 1998 | single-family houses, about 4 in 10 | gas, about 8 in 10 | 1980s and 90s gas houses, most on a second air conditioner, the part a heat pump would replace. |
| Brambleton | 2011 | townhouses, about 5 in 10 | gas, about 8 in 10 | Gas houses from the 2000s, where an aging air conditioner can give way to a heat pump. |
| Broadlands | 2004 | single-family houses, about 6 in 10 | gas, about 9 in 10 | Gas houses from the 2000s, where an aging air conditioner can give way to a heat pump. |
| Loudoun Valley Estates | 2013 | townhouses, about 6 in 10 | gas, about 8 in 10 | Gas houses built since 2012, most still on their original systems. |
| Belmont | 2005 | single-family houses, about 6 in 10 | gas, about 9 in 10 | Gas houses from the 2000s, where an aging air conditioner can give way to a heat pump. |
| Moorefield | 2015 | townhouses, about 6 in 10 | gas, about 7 in 10 | Gas houses built since 2012, most still on their original systems. |
| One Loudoun | 2015 | townhouses, about 4 in 10 | gas, about 7 in 10 | Gas houses built since 2012, most still on their original systems. |
| University Center | 1996 | condo and apartment buildings, about 4 in 10 | gas, about 8 in 10 | Condo and apartment buildings: compact closet systems, and the association decides where an outdoor unit goes. |
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.
When it’s time
Frost on the outdoor coil on a cold, damp morning is normal, and the unit melts it off now and then in a defrost cycle. A coil that stays solid white for hours isn’t. That points at the defrost controls, a sensor or the refrigerant charge, and on a Moorefield or One Loudoun unit around ten years old it’s often a repair.
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.
In an Ashburn townhouse the indoor half often sits in the attic or a top-floor closet, and getting it out is the hard part. Ask whether the quote covers that path, the drain pan and the backup strips.
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
Swapping one heat pump for another in a house or townhouse usually doesn’t. Virginia’s construction code exempts replacing mechanical equipment that burns no gas or oil, and Loudoun County’s pages don’t address electric swaps. An owner can still ask for a permit and inspection.
Yes, as the cooling half. When the air conditioner is due, a heat pump can take its place and carry the mild heating days, with the gas furnace for the real cold. Our dual fuel guide explains the pairing, and the HVAC estimator prices it.
$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.
