What’s different in Marshall
Marshall is the one village around here with a real mix of housing. In ZIP 20115 the Census counts roughly four in five owner homes as detached, but about one in nine is a townhouse, and a few more are in small apartment buildings or condos. Heat pumps carry about two in three owner homes, the highest share of any Fauquier village outside Bealeton, and nearly three in ten households rent.
In the townhouse rows, the outdoor units sit in a line on pads behind the units, and the air handler is in a hall closet or the attic. A noisy pump next door is an easy comparison: if a neighbor’s fan is spinning on a cold day and yours is quiet, that tells us something before we open a panel. The wall you share with the next unit also means the breaker panel is small and the circuit for the strips is shared with other load, so a long run of backup heat can trip a breaker that looks fine.
In the apartments and condos, the question is access. A unit on a shared pad or a roof needs the association’s or landlord’s go-ahead, and a tenant can’t authorize a repair on their own. If you are renting, your landlord is the one to call, and we can give them the findings in writing so the decision is quick. If you own, tell your manager a tech is coming so the gate or the roof is open.
Out on the farm lots, it is the other end of the same village. About a third of ZIP 20115’s homes went up between 1980 and 1999, so many of these are second or third systems. A June 2022 storm hit the Marshall area hard, and a pump that tripped then and has run oddly since may have a damaged contactor or control board.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20115 as a whole: every Marshall address, the village included. The Census place for the village alone has too few homes for steady figures.
What you’d notice
In a Marshall townhouse the backup strips can carry the whole house for weeks while the outdoor unit does little. If the house is warm and the bill is up, check the outdoor fan on a cold day: no fan, no heat pump, just expensive strips.
When the outdoor unit stops pulling its weight, the electric strips in the air handler carry the house. The house stays warm, and the bill tells you a few weeks later. A stuck contactor is a common reason, and one of the cheapest fixes on our list.
A little frost on a cold morning is normal, and the unit melts it off every so often by running backwards for a few minutes. Ice that builds for hours and covers the whole coil usually means the defrost board, a sensor, or low refrigerant.

Choosing who fixes it
Questions worth asking anybody who comes out, us included.
Ask whether the company will coordinate the visit with your manager or owner. In Marshall’s attached homes that single call decides whether the repair happens this week or next month.
Anyone can check on the state’s license lookup. Ours is Virginia Class A contractor license, on every van.
Every heat pump repair on our list has a range, and you hear where yours lands before a part goes in. If someone can’t give you a number until it’s done, keep looking.
An older heat pump with a refrigerant leak is often a bad repair. A good tech says so, with the repair price and the replacement price side by side.

Questions
Not necessarily. The same noise can be a capacitor in one unit and a failed contactor in the other. We test it, and our heat pump repair page explains the usual causes.
The diagnostic is $99. We test the outdoor unit, the air handler and the thermostat, tell you what failed and what it costs, and start work only once you’ve said yes.
That’s defrost. The unit stops the outdoor fan, runs backwards for a few minutes to melt frost off the coil, and you see steam rising. It’s normal. Ice that stays is not.
The diagnostic visit is $99. From our price book, a capacitor is $240 to $370, a contactor $290 to $425, and a defrost board $450 to $1,150. You get the number before we start.
Ready when you are
Call, or send the form at the top. The tech prices the repair from the book before starting, and if the system is at the end of its life you’ll hear that first.
