From the October 25 freeze to mid April, Middleburg ducts are on heat duty.
Freezing nights come early here. At the Purcellville weather station, the nearest with long records at Middleburg’s elevation, the median first freeze of fall lands on October 25 and the last of spring on April 16, with about 115 nights a year at or below 32 degrees. That’s close to half the year on heat, and for every one of those hours the blower is drawing the house’s air in through the return grilles.
Electricity heats 63 percent of the owner homes in 20117, and in a house here that’s most often a heat pump. A heat pump warms the house in long, steady runs rather than a furnace’s short hot ones, so its blower logs more hours. On the coldest mornings, like January 23, 2025, when a weather station in Middleburg read 4 below zero, it also brings on its backup heat strips, bare resistance coils mounted where all the air passes over them.
About one home in four in the ZIP went up in 1939 or earlier, decades before central air, and where those got ducts later, the installer threaded them wherever the framing allowed. Returns in a house like that are often few and small, and some pull straight from a wall cavity, a cellar corner or a crawlspace instead of a sealed duct. You see the camera photos before you see a price, and in an old house they often settle the question.
The newer houses, about a quarter of the ZIP built since 2000 and most of them detached, usually send the upstairs runs through the attic in flex. On July 28, 2023, weather stations across western Loudoun logged heat indices past 110 degrees, and an attic runs far hotter than that. A flex run slipped off its collar cools the attic instead of the bedroom.

What duct cleaning costs in Middleburg.
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 Middleburg.
The house is older than its ducts
In a 1920s or 1930s Middleburg house the ductwork is younger than the walls around it, and some of it went in piece by piece as rooms were finished or systems changed. Nobody kept a record of what’s inside, and the camera photos give you one.
Nobody remembers the last time
Which is most houses. Nobody opens a duct, so it never comes up until somebody looks.
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 Middleburg.
Questions to ask anybody who quotes you, us included.
Will they trace each return to where it draws air?
In an older Middleburg house, ask the tech to follow every return back to its source. One that’s open to a crawlspace, a wall cavity or a cellar corner fills the ducts faster than any filter keeps up with, and cleaning without finding it buys you a year.
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 Middleburg.
Does a duct cleaning need the Town’s approval in the Historic District?
No. Nothing outside the house changes, no Loudoun County building permit is involved, and the Town excludes routine maintenance from its Certificate of Appropriateness. What goes before the Historic District Review Committee is a new outdoor unit, fan or exhaust pipe the street can see.
Is a farm outside town, or the Fauquier end of 20117, the same price?
Same price book for every 20117 address, Loudoun side or Fauquier side: $598 for Whole Home Air Duct Cleaning up to 2,000 square feet, $298 for Return Air Duct Cleaning.
How much does air duct cleaning cost in Middleburg?
$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.
