Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

Why Hollis Air Duct Cleaning Is Villanova’s Preferred Air Duct Cleaning Company
We’ve built our reputation on the Main Line by showing up inside the window we promised and leaving the site clean. Villanova homeowners aren’t looking for the cheapest coupon in the mailbox; they’re looking for a crew that won’t track debris through a century-old foyer or treat a $2 million estate like a tract house.
Our technicians are background-checked, uniformed, and trained on The Garrison Code, which means they arrive squared away, explain the equipment they’re using, and price the job in writing before touching a single vent cover. That standard matters especially in Villanova, where many homes have original millwork, plaster medallions, and historic fixtures that demand care.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to schedule. When you’re ready, we’re ready.
Air Duct Repair in Villanova
Air Duct Repair in Villanova often means addressing galvanized or transite duct runs that have corroded, separated at the seams, or been compromised by rodent activity in unheated crawl spaces. On the old estate properties near Villanova University and along the Main Line, we regularly find ductwork that passes through stone foundation walls or unconditioned basements, where condensation and organic debris create a recurring black buildup that standard cleaning alone won’t fix. Repair costs in Villanova typically range from $400 – $1,200 depending on accessibility and material, with most jobs falling between $600 – $900.
Seam and Joint Restoration
Original metal ductwork in pre-war Villanova homes was often assembled with simple snap-lock seams and minimal sealing. Over decades, thermal expansion and the weight of accumulated debris cause these joints to pull apart, leaking conditioned air into walls and crawl spaces. We reseat the seams and apply professional-grade mastic, not duct tape, to restore airflow where it belongs.
Damaged Section Replacement
When a duct run has corroded through or been crushed during a prior renovation, we cut out the damaged section and splice in new galvanized or flexible ducting matched to the original system. On historic properties, we route carefully to avoid disturbing original plaster or lath, and we always verify the repair with a visual check before closing up.
Ductwork Cleaning in Villanova
Ductwork Cleaning in Villanova requires different approaches depending on whether your home is a 1920s stone estate with gravity-return chases, a mid-century ranch with galvanized trunk lines, or a newer build with flexible ducting in a finished basement. A typical residential ductwork cleaning in Villanova runs $350 – $650, with larger estate homes or systems with multiple air handlers ranging up to $850. We use Rotobrush rotary brush systems for mechanical agitation inside metal ducts, and Nikro negative-air machines to capture dislodged debris at the source, so nothing recirculates through your home during the job.
Whole-System Source Removal
Our standard residential cleaning covers supply and return ductwork, trunk lines, and accessible plenums. We attach a high-powered vacuum at the air handler and use compressed-air whips and rotary brushes to knock debris loose from the interior walls. The negative-air method creates suction at the collection point, so dust and allergens exit through our filtration system, not your living room.
Video Verification
Before we pack up, we run a camera through key duct runs and show you the footage. In Villanova’s older homes, this step often reveals issues the homeowner didn’t know existed: a disconnected flex duct behind a finished wall, a rodent nest in a crawl space branch, or corrosion pinholing a galvanized line. You’ll see exactly what we saw, and we’ll note anything that needs follow-up.
Trusted Brands We Service in Villanova
We clean and service systems with components from Honeywell, Aprilaire, and Guardsman, and we stock common filtration and hardware parts for faster turnaround on Villanova jobs. Many Main Line homes have Aprilaire media filters or Honeywell electronic air cleaners installed as retrofits to original systems, and our technicians know how to remove, clean, and reinstall these units without disrupting the surrounding ductwork. For homes with Abatement Technologies HEPA filtration or UV germicidal systems, we verify operation and recommend replacement intervals based on actual runtime, not a generic calendar. We also handle Dryer Vent Cleaning in Villanova and Duct Sealing in Villanova using the same equipment and the same written-price standard.
Common Air Duct Cleaning Problems We See in Villanova Homes
- Historic gravity-return systems clogged with decades of debris. The original 1920s – 1930s ductwork in Villanova’s grand estates was designed for coal or oil heat and never meant to handle modern filtration loads. We remove built-up soot, plaster dust from prior renovations, and organic matter without damaging fragile interior walls.
- Rodent nesting material in crawl space branches. Villanova’s wooded lots and stone foundations create ideal conditions for mice and chipmunks to access duct runs through gaps in exterior walls. We extract the nesting material, identify the entry point, and recommend sealing before the problem repeats.
- Condensation-related microbial growth in unheated duct chases. Ducts passing through stone foundation walls or unconditioned crawl spaces stay cold and damp, especially during humid Main Line summers. We treat visible growth and recommend insulation or rerouting where the building structure allows.
- Kinked flexible ducting in finished basements and attics. Newer Villanova homes and renovated older properties often have flex duct routed through tight spaces where it gets compressed or sagging, trapping debris and restricting airflow. We clear the blockage and support the duct properly to prevent recurrence.

FAQs About Air Duct Cleaning in Villanova
We typically schedule Villanova appointments within 3 – 5 business days, with limited next-day openings available depending on route density. Call (361) 326-5060 to check current availability, and we’ll hold a window that works for your schedule.
Yes, we work throughout Villanova, from the historic homes near Villanova University and the Main Line to the mid-century neighborhoods off King of Prussia Road and the newer infill developments near County Line Road. Our technicians are trained to protect original plaster, millwork, and historic fixtures during every job.
We do not offer same-day emergency dispatch for duct cleaning, which is a scheduled maintenance service rather than an urgent repair. If you have a sudden airflow loss, loud banging from the ducts, or suspect a gas leak, call your HVAC contractor or utility provider first. For routine cleaning with flexible scheduling, we’re available seven days a week.
Villanova’s pricing runs roughly 10 – 15% above the metro average due to larger home sizes, more complex historic systems, and the additional care required for original finishes. The tradeoff is expertise in century-old ductwork that cheaper outfits often lack. We still provide one flat price per system in writing before any work starts.
If any repair or sealing work we perform fails within one year of the service date, Hollis returns and makes it right at no charge, including a free second visit. This is backed in writing on every job, not a verbal assurance. The guarantee covers our workmanship and materials; it does not cover new damage from rodents, water intrusion, or unaddressed structural issues.
