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.

What’s different in Warrenton

In Warrenton the heat pumps are in the rentals and out on the bigger lots.

The Census counts a heat pump as electric heat, since it only asks about fuel. Inside the Town of Warrenton that’s 684 of the 2,509 owner homes, a little over a quarter. Among rentals it flips: 1,016 of the town’s 1,476 rented homes heat with electricity, about seven in ten.

In New Baltimore, which takes in Vint Hill, it’s 1,028 of 3,545 owner homes, close to three in ten. Across both Warrenton ZIP codes it’s about 3,700 of 10,070, close to four in ten, so the farms and big lots beyond the town and New Baltimore lean harder on electricity than either. Out there a heat pump often heats alone, so size it for winter, not just summer.

Where there’s gas, the usual heat pump job here is dual fuel, and the gas company matters. Our dual fuel guide shows where to set the handoff on Columbia Gas as well as Washington Gas. Its Washington Gas rebate doesn’t reach the town, where the gas is Columbia Gas of Virginia’s, and Columbia’s rebate list has no heat pump on it. Out in New Baltimore, ask whoever sends your gas or propane bill what it offers before you choose.

The Town’s permit list leaves a straight swap alone: a heat pump’s outdoor unit replaced with the same type in the same spot needs no Town permit, while a move, or an upgrade calling for electrical or ductwork changes, does. Outside the limits, Fauquier County’s own rule applies, further down this page.

By the numbers

Warrenton 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 Warrenton

Inside the town limits, a little over 4 of the roughly 110 square miles the two Warrenton ZIP codes cover: the Historic District around Main Street, Leeds Square, and the streets off Broadview Avenue and Alwington Boulevard.

  • Median home built1993 Census
  • Built before 1980about 4 in 10 Census
  • Built since 2000about 3 in 10 Census
  • Most homes aresingle-family houses, about 5 in 10 Census
  • Heated withgas, about 6 in 10 Census
  • Rentedabout 4 in 10 Census
  • Most houses here burn gas, so a heat pump usually means dual fuel: it replaces the air conditioner and the furnace stays as backup.

The Fauquier County side

New Baltimore only. It’s the one Census place on the county side with mostly Warrenton mail, so the farms and lots beyond it aren’t in these figures.

  • Median home built1999 Census
  • Built before 1980about 3 in 10 Census
  • Built since 2000about 5 in 10 Census
  • Most homes aresingle-family houses, nearly all Census
  • Heated withgas, about 5 in 10 Census
  • Rentedabout 1 in 10 Census
  • Propane is common here; a heat pump beside a propane furnace carries the mild days and saves the tank for the cold ones.
  • Plenty of these houses still run the heat pump or air conditioner the builder installed.

When it’s time

When a heat pump in Warrenton is worth replacing.

It cools all summer, then blows lukewarm air all winter

On a heat pump that usually means a stuck reversing valve, a dead defrost control or a slow leak that shows in cold weather. About a third of the town’s homes date from the 1980s and 1990s; a heat pump original to one would be long past fifteen. The $99 diagnostic visit prices the repair and the replacement side by side.

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.

Fauquier County counts swapping an electric appliance for a similar one in the same spot as an ordinary repair that needs no permit. Moving an appliance to a new spot takes one. Source.

Choosing who installs it

How to pick the best heat pump installer in Warrenton.

Questions to ask anybody who quotes you, us included.

  1. Did they ask what kind of building it is?

    Inside the town limits, the Town’s permit list covers houses, duplexes and townhouses and treats apartment and condo buildings as commercial projects, and the association decides where an outdoor unit sits. Ask anyone quoting what kind of building it’s for.

  2. 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.

  3. 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.

  4. 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.

Questions

Heat pump replacement questions from Warrenton.

Will a heat pump keep a Warrenton house older than 1940 warm?

Often, once the ducts check out. About one home in six in town predates 1940, and ductwork in a house that age came later. A heat pump moves more air than a furnace at a gentler temperature, so we measure the runs before sizing, and a room the ducts can’t serve well can take a ductless head.

My Vint Hill heat pump has a propane furnace behind it. What gets replaced?

Usually just the heat pump half: the outdoor unit and the coil on the furnace, with the furnace kept as backup and the switchover set fresh for the new unit. If the furnace is as old and failing too, price both ways; a full heat pump system with its own air handler is $8,499 to $21,650 installed.

How much does heat pump replacement cost in Warrenton?

$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.
