What’s different in Falls Church
Roughly three in ten owner homes in the City of Falls Church heat with electricity, and a bit more on the Fairfax County side. Those numbers hide a split. More than a quarter of the City’s homes went up after 2000, mostly in the mid-rise buildings along Broad and Washington Streets, and out in Merrifield the blocks around the Mosaic district are newer still. That’s where the electric heat lives. The older streets are mostly gas, with a heat pump sometimes added beside the furnace.
The newer pumps fail differently. A variable-speed unit from the last ten years rarely dies on a capacitor. It throws a code: a sensor reading out of range, an inverter board that won’t talk to the thermostat, a fault the outdoor board logs and the wall display shows as a number. Write that number down, or photograph the screen, before anyone resets it. It’s often the fastest clue we get, and a power cycle can wipe it.
In those mid-rise buildings the outdoor half is usually on the roof, sometimes dozens of units in rows, with a refrigerant line running down through the building to an air handler in your closet. A long line set like that makes a slow leak harder to find, and roof access runs through the building’s management. Let them know we’re coming and ask who holds the roof key. It saves a trip.
Then there’s the other Falls Church. In a 1950s Lake Barcroft or West Falls Church house with a dual fuel setup, the gas furnace takes over whenever the heat pump can’t, so a broken pump can go unnoticed for weeks. The house stays warm. The sign is a gas bill that climbs in mild November weather, or an outdoor unit that sits silent on a 45 degree afternoon when it ought to be running.
Neighborhood by neighborhood
Census figures for each place, and what that usually means for a heat pump. Median year built and heat count owner-occupied homes only.

| Bailey’s Crossroads | 1980 | condo and apartment buildings, about 6 in 10 | electricity, about 5 in 10 | Mostly electric heat: heat pumps, and the bill shows trouble first. |
| Idylwood | 1975 | condo and apartment buildings, about 4 in 10 | gas, about 5 in 10 | Mostly electric heat: heat pumps, and the bill shows trouble first. |
| City of Falls Church | 1964 | condo and apartment buildings, about 5 in 10 | gas, about 7 in 10 | Condo units: small heat pumps, owner’s to fix. |

What you’d notice
On a Falls Church dual fuel system, the furnace covering for a failed heat pump looks exactly like normal heat from inside. Step outside on a mild afternoon while the heat’s calling. If the outdoor fan isn’t turning and the furnace is, the heat pump side has quit.
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.
A newer Falls Church heat pump with a communicating thermostat stores its own fault history. Ask whether the tech will pull those codes and explain them, instead of swapping parts until the error clears.
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
Usually not on the roof, but someone has to let us into the unit to reach the air handler and thermostat, and the building has to open the roof. Check your association’s rules for contractor access before the visit. The diagnostic is $99.
Not an emergency, since the furnace keeps you warm. It does cost you every day on gas. Often it’s a contactor at $290 to $425 or a defrost board at $450 to $1,150. For an inverter board on a variable-speed unit, the tech prices that part in writing before ordering it, and tells you if it’s time to look at replacement.
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.
