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 Catlett
Electric heat leads in Catlett: the Census counts 526 of the 1,040 owner homes in ZIP 20119 heating with it, and in a house built since the 1980s that usually means a heat pump outside and an air handler with strip heaters inside. With 270 houses from the 1990s and 201 from the 2000s, plenty of those heat pumps are on their second round.
Winter sets the size here, not summer. Warrenton 3 SE, the nearest NOAA normals station, averages about 4,700 heating degree days a year against about 1,000 cooling, and about five nights at 10 or colder. Fauquier County’s building code puts the winter design temperature at 17. A heat pump picked for July comes up short in January and hands the difference to the strips. Sized for 17 degrees, a cold-climate unit carries most of the winter and leaves the strips for nights like February 20, 2015, when that station read 2.
That station also logged 20.5 inches of new snow on January 23, 2016, and in December 2020 up to half an inch of ice built up in southern Fauquier. Every defrost sheds water, and on a low pad that water refreezes under the unit and climbs into the coil. A new one in Catlett belongs on a riser above the drifts, clear of a roof edge that drops ice.
Check the panel before the size goes up. Strip heat is the biggest electric load in most heat pump houses, and in Catlett the same panel often feeds a private well pump outside the village or, on the County’s sewer, the STEP tank’s pump. A bigger heat pump or strip kit only works if the panel and the air handler’s circuit have room, so that gets measured before the quote.
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.
ZIP 20119 as a whole: every Catlett address, the village included. The Census place for the village alone has too few homes for steady figures.
When it’s time
Light frost that clears on its own is normal defrost. A coil that stays solid white, or ice building from the base after freezing rain, means defrost or drainage has failed. Switch to emergency heat and book the $99 diagnostic visit before the compressor pays for it.
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 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.
Permits, locally
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
Questions to ask anybody who quotes you, us included.
Capacity drops as it gets colder, and the headline rating is measured at 47. Ask for the unit’s output at Fauquier County’s 17 degree design temperature next to your house’s heat loss at 17. If the first falls well short, the strips will be doing the work.
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
With help. A cold-climate heat pump keeps heating far below freezing, but at 2 degrees most lean on the strips, which is their job. Sized right, that’s a handful of nights a year.
The Census counts 131 Catlett owner homes that list wood as their main heat. There the heat pump covers the bedrooms the stove can’t reach, the nights nobody’s there to feed it, and all of the cooling. The $99 diagnostic visit prices the repair beside the replacement range.
$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.
