Water got up to the outdoor unit
With a floodplain through the village, a condenser in a low corner of the yard can stand in water after a hard rain. Keep the cooling off, let the ground drain, and have the electrical side checked before it runs.
An AC tune-up in Calverton is $99 per system. In a village with a floodplain through its middle, check the outdoor unit after storms.

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 Calverton
Calverton sits about 257 feet above sea level, and Fauquier County’s plan for the village says an extensive floodplain runs through the middle of it. NOAA’s storm records have Bastable Mill Road closed or blocked by high water four times from 2014 to 2024, and Bristersburg Road shut near Licking Run in August 2018.
Wind does its share. On August 29, 2024, a thunderstorm with winds estimated at 64 mph blew down numerous trees near Calverton, and in October 2011 a weak EF0 tornado from south of Midland ended its six-mile path roughly half a mile from the village. After weather like that, check the outdoor unit before cooling again: a limb on the top grille, twigs packed into the fins, a cabinet pushed off its pad, a waterline on its side. See any of those, leave it off and call us after the storm, and we’ll check it all.
Most Calverton houses get Catlett 20119 mail, and in that ZIP the typical owner’s house went up in 1990. About half heat with electricity, so the unit in the yard is usually a heat pump, and the Warrenton 3 SE weather station, six miles west-northwest, logs about four and a half times as many heating degree days as cooling ones in a normal year. By its spring tune-up, a Calverton heat pump has already come through its harder season.
The village core is older: by the County’s count, more than half of the 69 contributing buildings in the Calverton Historic District date from 1920 through 1960, built around windows and porches rather than ductwork. Where cooling came later it may be attic ducts or a ductless mini split, and each mini split head has its own coil, filter and drain. It’s the same $99 a system.
By the numbers
From the Census Bureau’s 2020 to 2024 survey, owner-occupied homes unless it says otherwise.
Calverton’s own ZIP, 20138, is post office boxes only, so the Census Bureau maps no area for it. These are ZIP 20119 as a whole, the Catlett ZIP area that holds nearly nine in ten of the Calverton Census place’s homes.
When to book it
With a floodplain through the village, a condenser in a low corner of the yard can stand in water after a hard rain. Keep the cooling off, let the ground drain, and have the electrical side checked before it runs.
It cools all summer and heats all winter, so it piles up more hours in a year than an air conditioner that sits idle from October to May.
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.
The indoor coil wrings water out of the air. Where that coil sits in an older Calverton attic, ask whether the tech clears the drain line, looks at the pan under it and tests the switch that stops the cooling if the pan fills.
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.

Showed up on time, worked quietly, recommended other maintenance procedures for my HVAC system. Good overall experience.
Questions
If a limb came down near it, water reached it or the power went out, yes. Ready.gov warns power can come back with surges that damage equipment, so leave the cooling off until it has held a while, then call us. Often same-day, and we will tell you honestly when we can get there.
Between the last frost and the first real heat. The station six miles away puts the median last freeze around April 9 and averages about 21 days a year at 90 or hotter, nearly all in summer. Book in April or May.
$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.
