Price in writing firstYou see every option priced before anything is ordered
What it costs
One price per system, $99. We go through it before a Northern Virginia July finds the weak part for you. Anything it turns up is priced in writing before any work, and if it can wait, we say so.
AC tune-up, one system
$99
Furnace tune-up, one system
$99
Heat pump, boiler or ductless mini split tune-up, one system
$99
Comfort+ membership, a cooling maintenance visit every spring included
$199 a year
A house with two systems books two tune-ups, one for each, and a heat pump or a ductless mini split is the same $99 a system. The heating side, a furnace or a boiler, gets its own tune-up in the fall at the same price.
With Comfort+ membership at $199 a year, the cooling maintenance visit comes every spring, along with a heating maintenance visit, a water heater flush with a sewer camera inspection and a dryer vent cleaning.
What’s different in Great Falls
Fairfax County’s dwelling records list central air on 5,822 of the 5,906 houses in 22066. How many systems a house runs depends on the decade. The 1970s, the biggest building decade here, left houses of about 2,600 square feet above ground, and plenty still cool with one system. The 622 built since 2010 run closer to 6,200, often split three ways, each zone with its own outdoor unit and its own $99 tune-up.
In a little over half the owner homes, the ones heated by natural gas or propane, the air conditioner sits off from fall to spring. Great Falls has many large and old trees, as the county’s plan for the area notes, and a condenser under them collects a winter of what they drop: leaves on the fan guard, and more slid down between the coil and the cabinet. Clearing that out and rinsing the coil from the inside comes first, before the fan starts on it.
The lower floors usually cool from a coil on the basement furnace or air handler, and more than eight in ten Great Falls houses have a recreation room down there. Below grade that coil’s water often can’t drain by gravity, so a small pump lifts it out, a wall away from finished carpet. The tune-up clears the line and pours water through until the pump kicks on.
Three in four houses here are two stories, and the bedrooms often run on a second system with its air handler in the attic. About four in ten owner homes heat with electricity, which usually means a heat pump out in the yard working both seasons, tuned up for the same $99 as a unit that only cools. Count the outdoor units before you book: each one is a system of its own.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
When to book it
Look down through the fan guard before the first warm day. Leaves on top mean more packed against the coil below. Leave the cooling off until the tune-up; starting the fan on a winter of debris is hard on the motor and its capacitor.
A weak capacitor is a small fix on a mild day in April. Found by a July heat wave, it’s a house with no cooling.
Or the sticker on the unit is from the last owners. That’s most houses, and it’s reason enough.
Choosing who tunes it up
Questions to ask anybody who books you, us included.
Under big trees the leaves that matter are inside the cabinet, against the coil, and a rinse from the yard leaves them there. Ask whether the tech lifts the top and cleans the coil from the inside out.
Ask what gets cleaned and what gets checked, and whether a second system costs extra. A number with no list behind it is hard to hold anybody to.
Ask for the findings in writing, with a price on anything that needs fixing and an honest word on what can wait. A tune-up you never see written down is one you take on faith.
An air conditioner doesn’t use up refrigerant. Low means it’s leaking somewhere, and a company that tops it up every spring is selling you the same refrigerant twice.

Elvis Diaz from SwiftPro did a fantastic job of inspecting my HVAC system, he explained everything in a very professional way, for example, he recommended the right filter type to use. It is a job well done.
Questions
Yes, three at $99 each, all on one visit. Each unit usually serves its own floor, so the write-up comes back by system, basement, main floor and bedrooms, and any repair is tied to the right unit and priced on paper first.
Yes. Of the 249 houses in 22066 built before 1960, about four in five are now on the county’s rolls with central air. Ducts added to a house like that go where they fit, often with one return for a whole floor, so the tune-up checks the filter and the airflow first.
$99 per system, the same for a central air conditioner, a heat pump or a ductless mini split. A house with two systems books two. If the tune-up turns up a repair, you get its price in writing before any work, and you decide.
Once a year, in the spring, before the first heat wave. The heating side gets its own visit in the fall. The filter needs attention more often, every one to three months, and it’s the cheapest thing on the list.
