Which electric company bills you shapes a Haymarket heat pump.
The Census counts a heat pump as electric heat, and across 20169 that share splits three ways. Inside the town limits, 170 of the 472 owner homes heat with electricity, and in a town where most houses date from the 1980s and 90s, that usually means a heat pump with backup strips. Across the whole ZIP it’s about one owner home in four, and in Bull Run Mountain Estates close to four in ten again.
The Town lists two electric companies, Dominion and NOVEC, and the one on your bill matters. Dominion’s Home Energy Evaluation program, for its own customers, lists a heat pump or mini split upgrade among its measures; it starts with an evaluation by one of its participating contractors, who files the rebate afterward. Our dual fuel guide notes that NOVEC doesn’t offer a heat pump rebate.
In a gas house, about six in ten owner homes in town, a new heat pump usually means dual fuel. In town that gas is Columbia Gas, and our dual fuel guide puts the handoff to the furnace for Columbia Gas customers at about 33 degrees on Dominion and about 9 on NOVEC. The guide’s Washington Gas dual fuel rebate isn’t open to a Columbia Gas account, and Columbia Gas’s own rebate list has no heat pump on it.
Up on the mountain about one owner home in eight burns propane, and a heat pump paired with a propane furnace carries the spring and fall and leaves the tank for January. Like for like, a heat pump going back in the old one’s spot needs no Prince William County permit; a unit in a new spot or one needing a new circuit does.
How the houses across Haymarket are heated.
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 |
|---|---|---|---|---|
| Bull Run Mountain Estates | 1978 | single-family houses, nearly all | electricity, about 4 in 10 | Little natural gas: heat pumps and propane furnaces. |
| Haymarket | 1995 | single-family houses, about 6 in 10 | gas, about 6 in 10 | 1980s and 90s gas houses, most on a second air conditioner, the part a heat pump would replace. |
Haymarket houses, 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 Town of Haymarket
Inside the town limits only, about one in eighteen of the owner homes with Haymarket mail. Dominion Valley, Piedmont and Bull Run Mountain Estates sit outside it, in the county.

- Most homes aresingle-family houses, about 6 in 10 Census

- In a townhouse the outdoor unit sits on a small pad out back, the indoor half in a closet or attic.

When a heat pump in Haymarket is worth replacing.
A heat pump on the mountain that came with the house
In Bull Run Mountain Estates close to four owner homes in ten heat with electricity, in houses mostly from the 1970s. If yours is a heat pump from a previous owner, the label’s year tells you how long it’s run. If it’s baseboard heaters instead, the real question is ductless.
The AC quit, and you heat with gas
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’s the one the builder put in
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.
The paperwork behind a new heat pump in Haymarket.
Town of Haymarket
The Town’s design guidelines ask that outdoor meters and mechanical, heating and air conditioning units be screened from public view by walls, fences, planting or a mix, and that roof-mounted equipment be screened on all sides. Source.
Prince William County
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.
How to pick the best heat pump installer in Haymarket.
Questions to ask anybody who quotes you, us included.
Did they ask which electric company bills you?
Inside the town limits it can be Dominion or NOVEC. Dominion’s program runs through its participating contractors, and in a dual fuel setup the handoff temperature sits far apart on the two.
Did they size it, or copy the old label?
Copying the old nameplate repeats whatever guess was made when the house was built. The wrong size runs worse in both seasons.
Is the air handler in the price?
A heat pump system is the outdoor unit plus the air handler inside. Ask whether the quote covers both, matched, in writing.
Who sets up the backup heat?
Set wrong, the electric strips run on mild days. Ask who programs the thermostat and at what outdoor temperature the strips may come on.

Heat pump replacement questions from Haymarket.
Does a dual fuel heat pump in Haymarket qualify for the Washington Gas rebate?
Only for a Washington Gas customer. Inside the Town of Haymarket the gas company is Columbia Gas, so that rebate is off the table there. On the county side, some of Prince William County is Columbia Gas territory too, so check the name on your gas bill before counting on it.
Can the new heat pump go somewhere else in my yard inside the town?
It can, but the Town wants outdoor heating and AC units screened from public view, and a new spot the street can see is a change for its Architectural Review Board. A move also turns a no-permit swap into County permit work. The old pad is the simplest place.
How much does heat pump replacement cost in Haymarket?
$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.
Should I get a heat pump, or a furnace and air conditioner?
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.
