A clogged AC condensate drain
A clogged condensate drain, a possible cause of the ceiling damage. The drain line was cut, flushed with nitrogen and tested with plenty of water, and it ran clear. Cooling was working properly afterward.
What’s in an Aldie house
One Aldie mailing address covers three very different kinds of home, and which one is yours decides most of what we find when we get there.
Stone Ridge, Kirkpatrick Farms and the other new neighborhoods hold nearly all of Aldie’s homes. The Census puts Stone Ridge’s median owner home at 2009 and counts more than half its homes as townhouses. Gas is the heat in close to eight in ten owner homes across 20105, so the usual pair is a gas furnace and a gas tank, often still the ones the builder installed.
Outside Stone Ridge the houses run younger, and more of them stand alone: across all of 20105 the median owner home dates to 2013, and about six in ten homes are single-family houses, against fewer than four in ten in Stone Ridge. About one owner home in twenty burns propane, and the equipment is new enough that the first question on a call is often whether it’s still inside the manufacturer’s parts coverage.
The old village grew up along the Little River Turnpike, now Route 50, around Aldie Mill, and the county protects it as a historic district. Its drains run to a small community treatment plant, its water comes from a private water company, and the farm lots around it mostly rely on their own wells and septic tanks.

What we fix in Aldie
A dedicated HVAC team and a dedicated plumbing team, working out of our shop on Lafayette Center Drive in Chantilly.
Most Aldie furnaces burn gas, and plenty are the originals, so a no-heat call here turns on the furnace’s age as often as on a part. Our Aldie furnace repair page prices the common repairs and sets a replacement figure beside them.
Stone Ridge’s design standards let you put a new air conditioner or heat pump where an approved one already sits without filing anything; a new location or an extra unit needs the association’s sign-off first. Common repairs are priced on our Aldie AC repair page, and duct cleaning and dryer vent cleaning each get a page of their own.
Houses this young have plastic or copper water lines and plastic drains, and under Loudoun Water’s rules the pressure regulator by the meter belongs to you. Tanks installed in the late 2000s are reaching the end of their run, and the water heater estimator prices a replacement with the permit counted.
What it costs
Our prices don’t change from one Aldie neighborhood to the next, and you get the number in writing before any work starts.
In Aldie, a new furnace and air conditioner installed together runs $8,898 to $23,000, and a heat pump system runs $8,499 to $21,650. The size of the house and the efficiency you pick set where yours lands.
Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works

Aldie paperwork
The new neighborhoods buy from Loudoun Water, which prints no hardness number and refers customers to the Corbalis plant Fairfax Water runs on the Potomac, 4.1 to 10.8 grains per gallon across 2025. The village is supplied by a private water company, and the farm lots pump from wells.
Reports: Loudoun Water, points you to Fairfax Water’s figures.
Aldie is unincorporated, so Loudoun County issues the permits. Replacing a gas furnace or a gas water heater takes one even like for like, though since October 2025 a swap at the same BTUs in the same place needs no plans. An electric unit replaced in its spot is exempt under Virginia’s code. In the village, most exterior changes also go to the county’s Historic District Review Committee before work begins.
Permit pages: Loudoun County.
On Loudoun Water’s sewer the building sewer is yours to maintain, Loudoun Water alone repairs the stretch in the public right of way, and its inspector looks at any replacement before the trench is backfilled. The village drains to a small community plant that Loudoun Water operates. On a septic system, the county’s advice is to pump the tank at least every five years.

Asked out loud
SwiftPro Heating, Cooling & Plumbing. Here’s what you can check: Virginia contractor license 2705192276, BBB Accredited with an A rating, and 5.0 stars across 1,136 reviews. It was named BusinessRate’s Best of 2026, the #1 heating contractor in Fairfax, Virginia. From an Aldie heating and cooling job in August 2026: A clogged condensate drain, a possible cause of the ceiling damage. The drain line was cut, flushed with nitrogen and tested with plenty of water, and it ran clear. Cooling was working properly afterward. We answer day or night, and we will tell you honestly when we can get there.
For mail, yes. The Stone Ridge Association’s office address carries the 20105 ZIP, which is Aldie’s, and the neighborhood sits in unincorporated Loudoun County. So it’s on Loudoun Water and under Loudoun County permits, and SwiftPro works there at the same prices as everywhere else it serves.
Public sewer, but not public water. Loudoun County’s 2019 General Plan lists Aldie among the rural villages on a public community wastewater system and says it’s the only one served by a private water company. Loudoun Water operates the treatment plant. Outside the village, most farm properties have their own well and septic tank.
For a gas one, yes, from Loudoun County, even when the new tank matches the old; since October 2025 one that matches in BTUs and location needs no plans. An electric tank replaced in place is exempt under Virginia’s building code. SwiftPro’s water heater estimator includes the permit in every price.
For homes on Loudoun Water, moderately hard to hard. Loudoun Water’s supply leans on Potomac water from Fairfax Water’s Corbalis plant, which ranged from 4.1 to 10.8 grains per gallon in 2025, softer in spring and harder by fall. That leaves sediment in a tank water heater every year. The village’s water company and private wells have figures of their own.
Replacing a run capacitor is $240 to $370, topping up refrigerant $190 to $740, and clearing a blocked condensate drain $175 to $420, the same book we use across Northern Virginia. In a townhouse with the air handler up in the attic, that condensate drain is the one worth keeping an eye on.
