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 Quantico
By the Census survey, about 120 of the Town’s roughly 310 occupied homes heat with electricity, and about 180 with gas. In the duplexes and small apartment buildings that hold more than half the Town’s homes, electric heat usually means a heat pump: an air handler in a closet, a condenser on a pad outside. A gas home is the other job, where a heat pump takes the air conditioner’s place beside the furnace.
A heat pump works through both seasons. The air station logs 4,002 heating degree days and 1,512 cooling degree days a year, so one machine works in January and again in July, when the average high is 88. That running time is what wears the capacitor, the contactor and the fan motor, in both seasons. For comparison, replacing a furnace and an air conditioner as a pair is $8,898 to $23,000.
Winters here are mild enough for a heat pump to carry most of the season. January averages a low of 28 and a high of 45, and the air station sees about two nights a year at 10 degrees or colder. The December 2022 Arctic front took wind chills near the tidal Potomac to around 5 below. On nights like that the backup heat does the work.
Nearly two in ten of the Town’s owner homes heat with oil, by a Census sample of about 50 homes. We don’t work on oil burners, but a switch to a heat pump is ours to price, and for a house moving away from oil the range at the top of this page is the place to start. The HVAC estimator works out the rest from your house.
When it’s time
A heat pump delivers air that feels cooler than a furnace’s even when it is working right. It’s a problem when the rooms still fall behind on a night near the average low of 28, or when the outdoor coil stays iced over. The tech who comes out for $99 can tell you which of the two it is.
It heats all winter and cools all summer, so it piles up hours an air conditioner never sees. Past 15 years, price the replacement beside any big repair.
Most heat pumps installed before 2010 hold R-22, which hasn’t been made since 2020. A leak on one is usually where recharging stops making sense.
Choosing who installs it
Questions to ask anybody who quotes you, us included.
A heat pump leans on backup heat when the temperature drops. Ask whether the quote includes electric strips or keeps your gas furnace as the backup, and how the thermostat decides between them. A quote that skips this has skipped the part you feel in January.
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.

SwiftPro came today to install our new HVAC system and they were fantastic. They were super courteous and well organized and kept the whole place clean and tidy the entire time. The price was reasonable and the whole experience was amazing. Highly recommend them!

Questions
Liberty Military Housing owns, manages and maintains the family housing aboard the base, so a failed heat pump goes to Liberty or the base Family Housing Office, not to us. Prince William County says it doesn’t serve federal property. In the Town of Quantico, houses and apartments are the work we price.
A heat pump clears frost from its own coil, but sleet and freezing rain are different: about a quarter inch of ice built up near and east of I-95 in February 2021. If the outdoor fan is encased in ice, leave the breaker off and call us instead of chipping at it.
$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.
