The unit is iced and boxed in
If your outdoor unit is white and sits tight against a wall or a screen, clear the space first. If the ice returns in a day or two, it is a defrost issue and the next step is a repair visit.

What’s different in Reston
In Reston the heat pump is usually hidden in a cluster or a condo, and what hides it is often what hurts it.
Barely a fifth of Reston’s owner homes are detached houses. The rest are townhouses in clusters, condos, and small multi-family buildings. That shapes every heat pump call here. The outdoor unit is probably tucked against a wall, behind a screen, or down a path between buildings, and the air handler is in a closet, a utility room or an attic. A heat pump needs air, and a lot of Reston’s units do not get enough of it.
That is the Reston fault we see most: low airflow. A screen too close, shrubs grown up around the condenser, a pad against a wall, leaves swept into the gap. The coil can’t breathe, the pump ices over, and it looks like a failed unit. Clearing a foot of space around the outdoor unit costs nothing and fixes a surprising number of winter calls. If it still ices, we have a real defrost fault to find.
Meltwater is the other Reston headache. A heat pump drips as it defrosts, and in a cluster, that water runs across shared walks and steps. A sheet of ice on a path outside a cluster door is a safety problem and a neighbor problem, and it can mean the unit’s drain or pad has shifted. Tell us where the water goes.
Condos around Reston Town Center and in the high-rises have what Tysons has: closets, shared roofs, building managers. Hunters Woods and South Lakes in 20191 are mostly older cluster homes from the 1970s, where the pump has probably been replaced and the air handler may be the original. North Point and the newer streets are 1980s and 90s, where capacitors and contactors wear around the twenty-year mark.

- A lot of homes here heat with electricity, most of them heat pumps, so a failing outdoor unit shows up on the power bill before it shows up as a cold house.
What you’d notice
What a heat pump in trouble in Reston usually does.
Aux or emergency heat that never goes off
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.
The outdoor unit is a block of ice
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
How to pick a heat pump repair company in Reston.
Questions worth asking anybody who comes out, us included.
Will they work around my association’s rules?
A tech who asks about your association before touching the outdoor unit is thinking ahead. Repairs rarely change where a unit sits, but a screen or a gate may need to open for access.
Is the company licensed in Virginia?
Anyone can check on the state’s license lookup. Ours is Virginia Class A contractor license, on every van.
Do they price the repair before they start?
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.
Will they tell you when it’s not worth fixing?
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
Heat pump questions from Reston.
Who do I call about ice on the walkway from my heat pump?
Your association first, if the walk is common property, and us about the unit. A heat pump should drain at its base. Water that crosses a walk usually points to a blocked drain or a pad that has settled.
My Reston townhouse heat pump is from the 1990s. Does it still make sense to repair?
For a capacitor at $240 to $370 or a contactor at $290 to $425, yes. If it is a major repair on an older unit, we lay the numbers out next to a replacement and let you choose.
Why does my heat pump in Reston steam and go quiet in the cold?
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.
How much does heat pump repair cost in Reston?
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.
