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 McLean
About three in four owner homes in 22101 heat with gas, and a house with nine rooms or more often splits the job between two furnaces: one in the basement for the main floors, one in the attic for the bedrooms. Each furnace is its own tune-up at $99. The attic one’s blower ran all summer for the cooling, but its burners haven’t lit since March, and the first cold night asks it to light, prove its draft and warm the bedrooms from a standing start.
If that attic furnace is a high-efficiency model, it makes water as it burns, and the small line draining it crosses attic air that falls below freezing on the coldest nights. When the water can’t get out, a safety switch stops the burners. That’s its job, and the reason a bedroom goes cold in January. Testing that switch with the other safeties is part of every tune-up.
McLean is where we see boilers most. Hot-water heat is a regular part of our McLean heating work, far more than anywhere else we go. A boiler is a different machine: no blower, no air to measure, and a fall visit built around the relief valve, the circulator pumps, the water pressure and the expansion tank. If baseboard or radiators heat your house, the boiler’s tune-up is the same $99 a system as a furnace’s; our boiler service guide covers what to check yourself first.
Tysons heats another way. More than four in ten owner homes in 22102 run on electricity, which in the towers usually means a closet heat pump with electric backup strips, tuned up for the same $99 a system. Most of the rest burn gas, often in a compact furnace fitted into a closet. Renting? Keeping the heat working is usually the owner’s job, so ask them first.
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 |
|---|---|---|---|---|
| McLean | 1977 | single-family houses, about 8 in 10 | gas, about 7 in 10 | Gas furnaces in older houses, often on a chimney shared with the water heater. |
| Tysons | 1985 | condo and apartment buildings, about 7 in 10 | electricity, about 5 in 10 | Condo buildings: mostly electric heat, small units in closets. |
By the numbers

When it’s worth doing
Close to a quarter of 22101’s homes went up since 2000, and a high-efficiency furnace in one usually vents out the side wall in two plastic pipes. Drifted snow, leaves, a new deck or overgrown shrubs can choke them, and a switch then shuts the burners off. Keep the pipes clear; the tune-up proves the switch still works.
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.
A boiler’s fall visit centers on water pressure, the relief valve and the circulators, which no furnace checklist covers. Ask whether it’s priced like a furnace. Ours is: the same $99 a system.
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
Yes, $99 each. Each one has its own burners, safeties and vent, and each gets its own readings.
Late September into October, once the air conditioning stops running every afternoon. The furnace gets tested on a mild day, and anything it turns up gets fixed before you need the heat.
Yes. About 2 in 100 McLean owner homes heat with propane, and a propane furnace gets the same tune-up, its burner pressure read for propane rather than natural gas.
$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.
