What’s different in Nokesville
Nokesville is really two housing stocks sharing a ZIP. In the village, about seven owner homes in ten heat with electricity, and the typical home dates to 1970. Across the wider 20181 ZIP the median is 1989 and more than a third of the owner homes went up since 2000. A heat pump in a 1970s village house and one in a newer subdivision have almost nothing in common when they fail.
In the village, more than a third of owner homes predate 1960. A heat pump there was added to a house built for something else: window units, a wood stove or a furnace long gone. Ducts tend to be tight, runs are long, and the pump works hard just to move air. The calls we see are icing, short cycling, and a house that never quite reaches the thermostat setting. We start by measuring airflow, because that’s what these systems most often get wrong.
In the newer subdivisions the pump is a more modern design, often with a board, a sensor and a variable-speed motor. When one of those quits, the symptom is usually an error code or a unit that runs at the wrong speed. A tech should read the code before touching anything, and the repair can be a sensor at $300 to $640 range or a board at $550 to $1,180, not a compressor.
Most Nokesville houses have a private well, and its pump sits on the same panel as the heat pump. When a storm takes the power and it comes back, both restart at once. A heat pump that trips its breaker on restart may simply be sharing a tired circuit. Tell us if the lights flicker when the well kicks in, because that tells us where to look first.
By the numbers

What you’d notice
On a cold morning go outside. If the heat pump is quiet and the house is still warm, the electric strips are carrying the load, and they use several times the power the pump would. A bill that doubles in January is how most people find out.
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.
In a village house from the 1970s the pump was added later, and the ducts weren’t made for it. Ask whether the tech will test airflow, because a pump that’s fine on paper can still be starved of air.
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.

Swiftpro did a great job fixing my heat pump to get my AC working again. They’re easy to work with and explained everything so that I was able to comprehend the issue well. They beat out other local competitors in price for the same service by 40%.

Questions
It can be, but it’s often airflow or a defrost board first. Light frost that clears is normal. A $99 diagnostic visit shows whether the defrost board at $450 to $1,150 is the answer or whether refrigerant is low.
A pump from before 2010 may hold R-22, and a leak there is often where repairs stop making sense. A small start part is still worth fixing. We show the replacement numbers next to the repair so you can decide with both in front of you.
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.
