Philomont: electric heat and propane each warm about 42 percent of owner homes.
The Census counts a heat pump as electric heat, and in ZIP 20132, the Purcellville-area ZIP that Philomont’s figures come from, electricity heats about 42 percent of owner homes. Another 42 percent burn propane. About 48 percent of homes there went up since 2000, and in a house that new, electric heat often means a heat pump with an air handler and backup strips. Take the HVAC estimator quiz and pick electric heat, and it prices a heat pump system for your house.
Winter is the test here. The Purcellville station counts 4,942 heating degree days against 1,050 for cooling, a January low averaging 24.5F and 114.7 days a year with lows at or below 32F. Philomont’s low hit -2F on January 23, 2025, and the coldest nights of the January 2026 arctic outbreak fell under Extreme Cold Warnings. On nights like those the backup heat does real work, so its size belongs on the quote.
Propane houses take a different route. A heat pump there can go on the pad where the air conditioner stood and work alongside the propane furnace. Set that beside a furnace and air conditioner done together, $8,898 to $23,000. The median owner home in the ZIP area dates to 2000, so a pair from that year is old enough that a heat pump is worth pricing.
Ground-source heating is something Loudoun County permits, through geothermal wells, and it is not the project priced here, which is an outdoor unit with an air handler inside. A house heating with oil today, about 6 percent of owner homes in the ZIP area, can ask us to price a heat pump in its place; the burner itself is not our work. Either way it runs on electricity, so storm outages count.
Philomont houses, by the numbers

When a heat pump in Philomont is worth replacing.
The air from the registers feels merely lukewarm
Heat pump air is warmer than the room but cooler than a furnace’s, so some of that feeling is normal. Air that feels cool on a January night near 24.5F is not. It points to a defrost fault, a refrigerant problem or a failing part, and the diagnostic visit at $99 finds which.
Aux heat is on all day
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.
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.
How to pick the best heat pump installer in Philomont.
Questions to ask anybody who quotes you, us included.
Do they size the heat pump for January, not just July?
The Purcellville station counts 4,942 heating degree days against 1,050 for cooling, so the winter load is the bigger one. Ask how the installer chose the size, what backup heat comes with it, and whether the quote names both before you sign.
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 Philomont.
Does Loudoun County allow a geothermal well for heating?
Yes, the county permits geothermal wells used for ground-source heating and cooling, apart from drinking-water wells. The heat pump priced on this page is an outdoor unit with an air handler inside, $8,499 to $21,650 installed. A ground-source system is a separate project.
I heat with propane. Is a heat pump worth pricing?
Worth a price, yes. The outdoor unit goes where the air conditioner sits and the propane furnace stays for the coldest weather. The heat pump system is $8,499 to $21,650 installed, against $8,898 to $23,000 for a furnace and air conditioner together, and the estimator narrows both to your house.
How much does heat pump replacement cost in Philomont?
$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.
