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 Manassas
Inside the city limits the City of Manassas owns the electric lines and sends the bill, and half its owner homes heat with electricity. The Census files a heat pump under electric heat, and in a house built around the City’s 1985 median that’s usually what it is: an outdoor unit that cools in July and heats in January, and an air handler with backup strips in a closet, the attic or the basement. Swapping that pair together is the like-for-like job.
The county side runs closer to four in ten on electric heat: Buckhall and Yorkshire at about 45 in 100, Loch Lomond near one in five. Where a house has gas, a heat pump usually takes the air conditioner’s spot and the furnace stays for the hard freezes, the pairing called dual fuel. In Buckhall’s roughly 460 propane homes, a propane furnace plays that part.
Close to three in ten City homes are townhouses, and in Sudley it’s closer to half. There the outdoor unit sits on a small pad a few feet from the neighbors’, and the air handler stands in a closet or lies in the attic. In a Bull Run condo, the association decides what replaces the outdoor unit and where it sits.
Independent Hill is nearly all single-family, half of it built since 2000, and a two-story house from those years often runs two systems: the upstairs one frequently a heat pump with its air handler in the attic, summers in the heat and winters in the cold. Each is priced on its own.
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 |
|---|---|---|---|---|
| City of Manassas | 1985 | single-family houses, about 4 in 10 | electricity, about 5 in 10 | Electric heat leads, which here means heat pumps: often a like-for-like swap. |
| Buckhall | 1995 | single-family houses, about 8 in 10 | electricity, about 5 in 10 | Electric a little ahead of gas: heat pumps in many houses, gas furnaces in the rest. |
| Sudley | 1977 | townhouses, about 4 in 10 | gas, about 6 in 10 | Older gas houses, where a heat pump pairs with the furnace once the ducts are checked. |
| Independent Hill | 2000 | single-family houses, nearly all | gas, about 6 in 10 | Gas houses from the 2000s, where an aging air conditioner can give way to a heat pump. |
| Bull Run | 1995 | condo and apartment buildings, about 5 in 10 | gas, about 7 in 10 | Condo and apartment buildings: compact closet systems, and the association decides where an outdoor unit goes. |
| Yorkshire | 1984 | single-family houses, about 4 in 10 | gas, about 5 in 10 | 1980s and 90s gas houses, most on a second air conditioner, the part a heat pump would replace. |
| Loch Lomond | 1968 | single-family houses, nearly all | gas, about 7 in 10 | Older gas houses, where a heat pump pairs with the furnace once the ducts are checked. |
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.
The whole City sits in ZIP 20110. It runs its own water, sewer and electric service.
Sudley and Bull Run in 20109, Yorkshire and most of Buckhall in 20111, Independent Hill in 20112, plus the county edges of 20110.
When it’s time
About half of Yorkshire’s homes are rented, and close to three in ten in the City. Virginia’s landlord and tenant law makes heat in season the landlord’s job, so a heat pump limping on its backup strips is better replaced between leases than on a January night.
When the heat pump can’t keep up, the electric strips take over, and they cost far more to run. Aux heat on for hours is the sign.
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.
Permits, locally
The City’s mechanical permit covers the first-time installation of heat pumps and central air conditioning, and the replacement of gas furnaces. Source.
Prince William County lists any work that alters a home’s heating and air conditioning as permit work, but swapping an electric furnace, heat pump or air conditioning condensing unit for the same type of unit in the same spot is an ordinary repair that needs no permit. Source.

Choosing who installs it
Questions to ask anybody who quotes you, us included.
A new air handler can be taller or wider than one from the 1980s, and in a Manassas townhouse it has to go back through the same closet door or attic opening. Ask whether they measured it.
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
Usually not for a heat pump replacing a heat pump in a house. Inside the City, a replacement that runs on electricity alone is on the no-permit list, though a first heat pump is mechanical permit work. Prince William County skips the permit for the same kind of unit in the same spot, so an air conditioner turned into a heat pump, or a condenser relocated across the yard, goes through the county first.
Usually, once the ductwork is checked. Ducts that age were laid out for a furnace’s hot air, and a heat pump heats with more air at a milder temperature, so a marginal return can become the limit. We measure the ducts before pricing.
$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.
