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 Clifton
Clifton houses run big. About 62 percent of the homes in 20124 have at least nine rooms, against 28 percent countywide, and a house that size is often cooled by two systems, one for the main floor and basement and one for the bedrooms. That second air handler often sits in the attic, where nobody walks past it. Each system is its own tune-up at $99, with its own written findings.
Up there the coil sweats all summer into a pan, and the water leaves through a drain line laid across the attic floor. Dust and the slime that grows in standing water narrow that line a little every season, and when it backs up, the bedroom ceiling is next. Clearing the drain line is part of every tune-up, and on an attic unit it’s the part that pays for the visit.
Around the town and out on the big lots along Clifton, Compton and Yates Ford Roads, about half the owner homes heat with electricity, which out here usually means a heat pump. That outdoor unit heats all winter, defrosting itself on frosty mornings, then goes straight to cooling. Book it in the mild weeks between the last cold night and the first hot one.
Around Springstone Drive it’s another picture. About nine in ten of those homes went up in the 1980s, and about 85 percent of the owners heat with natural gas, so the cooling is a condenser out back piped to a coil above the furnace in the basement. Most of those houses are on their second or third condenser by now, and the coil indoors is sometimes older than the one outside.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Clifton mail outside the town: five- to ten-acre lots in the Occoquan watershed on Clifton, Compton and Yates Ford Roads, mostly on septic, and the 1980s subdivisions off Springstone Drive and Union Mill Road on county sewer.
ZIP 20124 as a whole, the Town included: its own homes are too few for steady Census figures.
When to book it
If you can reach the upstairs air handler, look in the pan underneath it. Water sitting there in spring means the drain line is already slow. Book the tune-up then, while the fix is a cleared line and not a stained ceiling.
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.
In a two-system Clifton house the upstairs air handler is the harder one to reach, often up a pull-down ladder. Ask whether both get the coil, the fan and the drain line done, each with its own line on the written findings.
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. Its outdoor coil collects leaves and grit through the heating months too, and it goes straight into cooling with no break. The spring tune-up is $99 per system, and the findings say what the winter did to it.
Usually the drain. The Town’s houses are almost all over 120 years old, so the cooling went in later, wherever it fit. A unit that low often can’t drain by gravity, so a small pump lifts the water out; when it quits, the water stays under the house. The tune-up clears the drain line, and the findings say how the pump looked.
$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.
