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 Leesburg
The Census counts a heat pump as electric heat, and on a Leesburg address that count is lopsided. Inside the town limits close to three owner homes in ten heat with electricity, roughly 3,400 of them. In Lansdowne it’s about one in five, nearer 700. So most heat pumps behind a Leesburg mailbox are in town, where the median owner home dates to 1996.
A heat pump works every month of the year, so it wears faster than an air conditioner of the same date. One the builder set in a 1996 house would be thirty; most have likely been replaced already, and a replacement installed before 2010 may still hold R-22. The label on the outdoor unit gives the refrigerant and usually the year, and both matter before anyone recharges it.
Lansdowne leans even harder on gas: about eight owner homes in ten burn it. There a heat pump usually arrives when the air conditioner is due, set on the same pad beside the furnace, the pairing our dual fuel guide walks through. In its condo buildings, close to four homes in ten, the association decides where an outdoor unit may sit.
Downtown, the outdoor unit is the part the Town cares about. Its Old and Historic District guidelines want mechanical units at the side or rear of the house, screened from the street, and the Town asks owners to call its preservation staff before exterior work to learn whether a Certificate of Appropriateness is needed. That holds even where a straight swap needs no building permit.
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 |
|---|---|---|---|---|
| Leesburg | 1996 | single-family houses, about 4 in 10 | gas, about 7 in 10 | 1980s and 90s gas houses, most on a second air conditioner, the part a heat pump would replace. |
| Lansdowne | 2005 | condo and apartment buildings, about 4 in 10 | gas, about 8 in 10 | Gas houses from the 2000s, where an aging air conditioner can give way to a heat pump. |
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.
Inside the town limits: the Old and Historic District downtown, Exeter and Carrvale inside the bypass, Potomac Station and Edwards Landing outside it.
Lansdowne only. It’s the one Census place outside the town limits, so the farms and lots beyond it aren’t in these figures.
When it’s time
In a Leesburg townhouse the heat pump’s indoor half is often up in the attic, over a bedroom. A rusted drain pan or a clogged condensate line shows up first as a stain below it. On a system past fifteen, have the $99 diagnostic visit put a repair price next to the replacement range.
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 a 1990s Leesburg townhouse the refrigerant lines between the outdoor unit and the attic often run inside finished walls. Reusing them avoids opening drywall; replacing them can still be the right call. Ask which one the quote assumes, and why.
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.

Moises and Oscar did a superlative job doing a custom installation of a new HVAC unit in a tight basement space. And they then took the time to go over system operation. Top tier job and service in all respects!

Questions
For a like-for-like swap in a house or townhouse, usually not. Virginia’s building code exempts replacing mechanical equipment that burns no fuel, though an owner who asks gets a permit and inspections. Moving the outdoor unit or adding a system is permit work, and Loudoun County issues it, inside the town limits as well as out.
Open the closet. A gas furnace has a gas pipe and a vent pipe running out of it; a heat pump’s air handler has neither, just copper refrigerant lines and wiring. Outside, a heat pump’s unit runs in January as well as July. Close to three owner homes in ten in town have the electric kind.
$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.
