Most homes haven't had ducts cleaned in 10+ years. Dust, allergens, mold spores, pet dander, and even rodent debris build up — and that's what your HVAC is circulating.
We use NADCA-aligned methods: source-removal vacuum trucks, mechanical agitation, before-and-after photos. Same-week scheduling across the Main Line.
NADCA source-removal method — truck-mounted negative pressure with mechanical agitation through every supply and return. Before and after photos.
The fire-risk and slow-drying problem most homeowners forget about. Dedicated brushes through the full vent run, lint volume measured.
Drywall dust, sawdust, and construction debris pulled out before it circulates through your house for a year.
After a fire, smoke event, water loss, or mold remediation, ducts often need decontamination as part of the broader job. Different scope, different methods.
Walk the system before we touch it. Photos of every vent and the return. Concerns and trouble spots logged.
Truck-mounted vacuum hooked to the trunk line so debris pulls toward the truck — not into your living room.
Brushes and air whips loosen what is stuck to the duct walls so the vacuum can actually pull it out. This is what most cheap "cleanings" skip.
Before-and-after photos shared. Dryer vent service handled separately if scheduled. Appointment usually completes in 3–4 hours for a typical residential system.
If you are in the middle of an active loss right now, these are the things that protect your property and your safety while a crew is on the way.
There is a real difference between a $99 special and a real duct cleaning. The cheap version blows compressed air for 30 minutes and leaves with most of your dust still in the system. The right version uses NADCA source-removal: a truck-mounted vacuum creating negative pressure across the entire system, paired with mechanical agitation through every branch so the buildup actually moves. We show you before and after photos so you know what came out — not just what we say came out.
Every 5–7 years for most homes. More often with pets, allergies, recent renovation, or a prior water/fire event. Less often for tightly built newer homes with quality filtration.
There are scams in this category — $99 specials that do not actually clean. Legitimate duct cleaning uses negative pressure and mechanical agitation, takes 3–4 hours for a typical home, and shows you photos of what came out.
Often, yes — especially if your symptoms worsen when the HVAC runs, you have pets, or the system has not been cleaned in a decade. It is not a cure for outdoor allergies, but indoor air quality measurably improves.
About 3–4 hours for a typical residential system. We protect floors, photograph access points, run negative pressure across the whole system, agitate every branch, and clean dryer vents separately if scheduled.
Yes. The dryer vent is a separate run that does not connect to the HVAC system, and the cleaning method is different. Lint buildup is one of the leading causes of home fires in PA each year — it is worth doing.
A real person answers most calls in under 60 seconds. For active emergencies on the Main Line, our goal is a crew on-site within 60–90 minutes from dispatch. For scheduled work, we book within 24–48 hours.
Yes. We document scope, photos, moisture readings, and equipment hours in a format your carrier expects. Most claims we coordinate with the adjuster directly so you are not stuck translating between us and them.
