What’s different in Middleburg
About six owner homes in ten here heat with electricity, more than anywhere else in the western towns we cover, and only a handful use piped gas. For most Middleburg houses that makes the heat pump the heat, full stop. With the median owner home dating to 1986 and over a third built before 1960, a lot of those pumps are in houses that started life with a fireplace and a boiler, and the pump is a later addition.
In the village, the old houses sit close to the street with small lots, so the outdoor unit goes where it fits, often a side yard or against a wall, with a screen the Town prefers. A screen can hurt a heat pump in winter, because boxed in tight it pulls its own cold air back in and ices over. If your unit built a block of ice behind a lattice, move the lattice before you spend on parts.
Outside the village, the farms and estates are bigger and the pumps are many. A big old house may run three or four systems, each a different age, and some are zone units that serve one wing. When only one end of the house is cold, it is one pump, and the repair is on that unit. Tell us which part of the house is cold and we start with the right unit, so a visit doesn’t turn into a search.
Because heat pumps are the main heat in so many homes, the backup matters. Most have electric strips, and a few have a propane furnace beside them. A pump from before 2010 may be on R-22, which the EPA stopped making in 2020, and a big leak there belongs in the replacement conversation. A capacitor or contactor, on the other hand, is a small fix on any pump, and the sooner you do it the better the compressor fares.
By the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
ZIP 20117 as a whole: every Middleburg address, the Town and the farms around it, about a tenth of the land in Fauquier County. The Census place for the Town alone has too few homes for steady figures.
What you’d notice
In a big older Middleburg house with several heat pumps, a cold wing usually means one unit, not all of them. Check which thermostat serves that wing and which outdoor unit it matches. If one is silent while the others run, it is often the contactor, at $290 to $425.
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.
With a farmhouse or an estate, there may be several heat pumps and several thermostats. A tech who starts by matching them up saves you a long visit. One who just picks a unit will be there a while.
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.

Excellent work done honestly and efficiently. Efrain the technician was great. Was able to diagnose the problem quickly and get my older Amana gas furnace system working again.

Questions
It can be. A tight enclosure makes the unit breathe its own chilled air in winter and ice up. The screen should leave open space around and above the unit, and be the right kind of slatted material. If yours iced up after a screen went in, that is the likely cause.
Yes, in 20117 and past it. Farms often have several units of different ages, so give us a list of what serves what. If one is too old to be worth fixing, a replacement is priced next to the repair.
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.
