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 Triangle
Triangle’s weather numbers come from the Marine Corps air station at Quantico, 3.8 miles south-southeast, down on the Potomac shoreline. Its 1991 to 2020 normals put the average July high at 88 degrees and add up 1,512 cooling degree days a year, and on July 22, 2011 it measured a heat index of 118. A system here logs long afternoons all summer, so the spring visit is when a pitted contactor or a coil caked with last fall’s leaves should turn up, not during the first 90 degree week.
About half of Triangle’s homes went up after 2000. County plat records date Kerill Woods to 2001 and Lionsfield Valley and Cramers Ridge to 2004, so houses from that run got their condensers within a season of their neighbors, and plenty of those builder units are past twenty summers now. One that old most likely runs on R-22, which hasn’t been produced or imported in this country since 2020. If the write-up says it’s low, the useful talk is where the leak is and how many summers the unit has left.
Graham Park is the other Triangle. Its first plat was recorded in 1950, Carborough Heights is older still, and about one home in six here predates 1960. Nobody built central air into those houses. Where it came later, the ducts often snake through an attic or crawlspace never planned for them, and the return grille may be a size too small. A coil starved of air runs cold enough to ice, so in an older house the tech checks the airflow indoors first.
Summer storms here bring wind and water. The June 2012 derecho threw a 66 mph gust at the Quantico station, and an August 2022 thunderstorm knocked trees down in Triangle near Route 1, Cabin Road and Locust Shade Drive. Before switching the cooling back on after one, look at the condenser: limbs on the top grille, leaves pasted to the fins, the unit shoved off level, insulation torn off the copper lines. Near Little Creek, where a June 2018 flood submerged a car at Route 1 and Fuller Road, a unit that sat in water stays off until it’s checked. Call us after a storm and we’ll check it all.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
When to book it
On an original 2004 unit, a house that creeps up a degree or two through a hot afternoon and only catches up after midnight usually has a dirty coil, a tiring fan motor or a slow leak. A tune-up tells you which. Book it before the next hot stretch.
A house from the 2000s often runs its first air conditioner, now 15 to 25 years old. A yearly look tells you how much life it has left before a hot week does.
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.
Choosing who tunes it up
Questions to ask anybody who books you, us included.
On a builder unit from the early 2000s, those two facts decide whether a repair is worth making. Ask for both in writing, read off the nameplate, so a replacement is something you plan over the winter, not something you shop for in July.
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.

Questions
No. Liberty Military Housing owns, manages and maintains the family housing aboard Marine Corps Base Quantico, so cooling trouble in an on-base home goes to your housing office. Off the base, any house, townhouse or condo with Triangle mail is $99 a system.
$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.
Ready when you are
Call, or send the form at the top. Anything the tune-up turns up gets priced in writing before anybody touches it, and if it can wait, you’ll hear that too.
