What it costs
$99 for one furnace, anywhere we work. The tech checks the gas pressure, the temperature rise, the safeties and the sequence of operation, which is the order the furnace lights, heats and shuts down in. A repair it turns up gets a written price first, and you decide.
Furnace tune-up, one system
$99
Heat pump, boiler or ductless mini split tune-up, one system
$99
Comfort+ membership, a heating maintenance visit every fall included
$199 a year
It’s priced per system, so a house with a second furnace for the upstairs is two tune-ups. A heat pump, a boiler or a ductless mini split is the same $99 a system.
With Comfort+ membership, $199 a year or $20 a month covers four visits every year: a heating maintenance visit in the fall, a cooling maintenance visit in the spring, a dryer vent cleaning, and a water heater flush with a sewer camera inspection. We book each one when it’s due.
What’s different in Alexandria
Fort Hunt is the plainest gas furnace neighborhood on the Alexandria address: nearly every home is a detached house, the typical owner’s went up in 1963, and about 8 in 10 heat with gas. A house that age is likely on its third or fourth furnace, down in the basement. Hayfield, its typical house from 1978, has close to 9 in 10 on gas. There the tune-up comes down to readings: the gas pressure read at the valve and the temperature rise from return to supply, checked against the range on the furnace’s rating plate.
Kingstowne went up mostly in the late 1980s and 1990s, close to half of it townhouses, with roughly 7 in 10 owners burning gas. Plenty of the builder’s furnaces have been replaced by now, often with a high-efficiency model venting out the wall in white plastic pipe. On those the tune-up watches the whole start: the inducer spins up, the pressure switch proves the vent is clear, the igniter glows, the gas valve opens, the flame sensor proves the flame, and the blower comes on. That’s the sequence of operation, and a furnace that stumbles in it on a mild October day will do it again in January.
Inside the City we still work on boilers and radiators; on the Fairfax County side they’re rarer. A boiler’s tune-up is the same $99 a system as a furnace’s, and so is a heat pump’s in Franconia or Woodlawn. More than half the City’s homes are in condo and apartment buildings, where the furnace is often a compact unit in a hall closet. The City’s own winter safety page asks for three feet of clear space around heating equipment, a carbon monoxide alarm on every level of the home and outside the bedrooms, and the furnace vent dug out of the snow after a storm. In a closet, those three feet are the hard part, so clear it out before the visit.
Propane is rare on the Alexandria address, but Hybla Valley has the most: close to 1 in 20 homeowners there heat with it. Propane furnaces are set up for a higher gas pressure than natural gas ones, so the tune-up reads yours against propane’s numbers. Franconia and Woodlawn lean electric, and there a gas furnace is the smaller share of the heat.
Neighborhood by neighborhood
Census figures for the owner-occupied homes in each place, and what that usually means for a tune-up.
| Place | Median home built | Most homes are | Heated with | What the tune-up usually meets |
|---|---|---|---|---|
| City of Alexandria | 1970 | condo and apartment buildings, about 5 in 10 | gas, about 6 in 10 | Condo buildings: compact gas furnaces in closets. |
| Rose Hill | 1969 | single-family houses, about 7 in 10 | gas, about 7 in 10 | Gas furnaces in older houses, often on a chimney shared with the water heater. |
| Franconia | 1986 | townhouses, about 5 in 10 | electricity, about 6 in 10 | Mostly heat pumps; furnaces are the smaller share. |
| Fort Hunt | 1963 | single-family houses, nearly all | gas, about 8 in 10 | Gas furnaces in older houses, often on a chimney shared with the water heater. |
| Kingstowne | 1994 | townhouses, about 5 in 10 | gas, about 7 in 10 | Townhouse furnaces in closets and attics. |
| Woodlawn | 1976 | townhouses, about 4 in 10 | electricity, about 6 in 10 | Mostly heat pumps; furnaces are the smaller share. |
| Lincolnia | 1982 | single-family houses, about 4 in 10 | gas, about 7 in 10 | 1980s and 90s houses, most on their second gas furnace. |
| Mount Vernon | 1967 | single-family houses, about 7 in 10 | gas, about 7 in 10 | Gas furnaces in older houses, often on a chimney shared with the water heater. |
By the numbers

When it’s worth doing
That usually means the furnace can’t prove its flame, most often because the flame sensor is coated, so it closes the gas and tries again. It’s a small part, and finding it in October beats finding it before dawn in January.
The heat in your closet is usually yours to look after, not the association’s. Check your documents, then book it like any house.
That’s the night every furnace in town gets asked to work at once. A tune-up in the fall finds a weak part while you still get to choose when it’s fixed.
Safety and paperwork

Choosing who tunes it up
Questions to ask anybody who quotes you, us included.
Ask whether the tech runs it from cold and watches each step, inducer to flame to blower. A furnace that’s going to quit on the first frosty morning often hesitates somewhere in that order first.
Ask before anyone comes out. Gas pressure and temperature rise are readings on a meter, so a real tune-up has numbers in it, not just a look at the filter.
Some tune-ups end in a list. Ask which items are failing now, which can wait a season, and what each one costs, before you agree to any of it.

Questions
Late September or October: after the air conditioning is done and before the first morning you’d want heat, so any repair it finds gets fixed when it suits you.
$99 for one furnace, and the same for a heat pump, a boiler or a ductless mini split. If it turns up a repair, you get the price in writing before any work, and you decide.
No. The furnace tune-up is its own visit at $99. The Heating Check and the Clean Heat deep clean, the one that takes the blower wheel out and cleans it, are separate offers with their own terms on our Clean Heat page.
