In Round Hill the ducts work hardest in January, not July.
Round Hill once drew summer people escaping Washington’s heat, and the weather still leans that way. The Purcellville co-op station, about three miles off, averages roughly 4,940 heating degree days a year against 1,050 cooling, and around 115 nights at or below freezing. The blower in a 20141 house spends far more hours pushing warm air than cool, and every hour pulls the house’s air back through the returns.
What heats the house sets the pattern. About half the owner homes here heat with electricity, which in a house this age usually means a heat pump, and on a night near the January average low of 24.5 degrees a heat pump may barely shut off. Another four in ten burn propane in a furnace whose blower serves the same ducts the air conditioner uses in summer.
The subdivisions around the town went up mostly between the mid 1990s and 2005, and the typical owner’s home dates from 2004. Plenty of those basements were finished later, and inside the town limits a finished basement, an addition or an interior remodel starts with a Town zoning permit. If the system ran while somebody sanded drywall downstairs, that dust went into the returns, and the camera photos will show it.
The old town is the exception. The Town’s plan says most houses inside its limits went up before the end of the 1920s, long before central air, so the ducts in a house on Loudoun Street or Main Street were fitted in later, through closets, chases and attic corners. Some of those houses may cool with ductless heads and have little to clean, which the camera settles first.
Round Hill houses, by the numbers
From the Census Bureau’s 2020 to 2024 survey. Median year built and heat count owner-occupied homes only.
Round Hill
ZIP 20141 as a whole: every Round Hill address, the Town and the neighborhoods around it. The Census place for the Town alone has too few homes for steady figures.
- Median home built2004 Census
- Built before 1980about 2 in 10 Census
- Built since 2000about 6 in 10 Census
- Most homes aresingle-family houses, about 9 in 10 Census
- Heated withelectricity, about 5 in 10 Census
- Rentedabout 1 in 10 Census
- Newer houses run flexible duct, which needs a softer brush than sheet metal.
- Bigger single-family houses often run two systems, and each is its own cleaning.
What duct cleaning costs in Round Hill.
The same price book as our air duct cleaning page, for a home up to 2,000 square feet on one system. We look first: the tech takes a cover off, puts a camera in and photographs what’s in your ducts, then shows you, so you see their current condition before you decide. No charge, including when yours are fine. Then you get the price in writing, then we clean.
- Return Air Duct Cleaning$298
- Whole Home Air Duct Cleaning$598, regularly $798
- Whole Home Air Duct Cleaning with ActivePure Air Scrubber$1,798
- Dryer Vent Cleaning, on its own$298
- Dryer Vent Cleaning, added to a duct cleaning$199
A second system bills at 90 percent of the tier, because it’s isolated and cleaned on its own. The calculator on our air duct cleaning page does the arithmetic for a bigger house.
The dryer vent cleaning is the yearly one, and it’s in Comfort+ membership at $199 a year along with a water heater flush with a sewer camera inspection, a heating maintenance visit and a cooling maintenance visit.
When duct cleaning is worth it in Round Hill.
The basement got finished after you moved in
Sanding drywall is the dustiest job a house goes through, and the heat pump or furnace usually keeps running during it. If the new rooms’ registers were tapped off the original trunk, that dust had a ride to every floor.
The house is new to you, not new
A 2005 house has had twenty years of filter changes, some of them missed, and the system may have run while the drywall went up. Nobody has looked inside since.
You just bought the place
You don’t know whether the last owners had three cats or ever took a register cover off. Most new owners want it done once, early, so they know what they’re starting with.
What the county says about dryer vents.
Loudoun County
Ashburn Volunteer Fire and Rescue, one of the companies in Loudoun County’s fire and rescue system, says the dryer vent, from the back of the dryer to the outside of the house, should be cleaned at least once a year, and that longer drying times are a sign it’s clogged. Source.
How to pick the best duct cleaning company in Round Hill.
Questions to ask anybody who quotes you, us included.
Will they look at the attic runs, not only the registers?
In a two-story 20141 house the upstairs ducts often run through the attic as flexible duct, where a run can sag, kink or slip off its collar into the insulation. On the 30 or so afternoons a year Purcellville tops 90 degrees, that attic runs far hotter. Ask whether the tech checks those runs.
Do they look before they quote?
Ask whether they’ll put a camera in and show you photos of what’s inside first. A price given at the door, sight unseen, is a price for the average house, not yours.
Do they clean the returns, or only the supply vents?
The returns are the big grilles that pull air back to the system, and they’re the side that collects dust. A job that only counts supply registers leaves half the system alone.
Is the price for the whole system, in writing?
Ask what it covers: every supply and return, the main trunk, the blower compartment. The $59 mailbox coupon covers getting somebody into the attic.

Duct cleaning questions from Round Hill.
Does Round Hill’s hard water have anything to do with my ducts?
Usually not. The one place it can show up is a whole-house humidifier on the furnace or air handler: its pad sits in Town water, which tests as high as 317 mg/L of hardness, and the pad can crust over. If yours has one, ask the tech to look at it while the system’s open.
Do you clean ducts in the Villages of Round Hill, Stoneleigh and out toward Airmont?
Yes, all of 20141 from one price book, town limits or not: $598 for Whole Home Air Duct Cleaning up to 2,000 square feet, $298 for Return Air Duct Cleaning. Count the outdoor units before you call; every system gets cleaned on its own.
How much does air duct cleaning cost in Round Hill?
$598 for Whole Home Air Duct Cleaning, regularly $798, on a home up to 2,000 square feet with one system, $298 for Return Air Duct Cleaning, and $1,798 with an ActivePure air scrubber installed. A dryer vent is $298 on its own or $199 added to a duct cleaning.
Is it worth it?
Sometimes, and the camera photos are how you find out. If the duct walls are furred over, cleaning takes that out of the loop your air runs through, and the before and after are obvious. If the metal is clean, it isn’t worth doing and we’ll say so. The EPA’s position is that routine cleaning hasn’t been shown to prevent health problems, so we don’t sell it that way.
