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.

AfterFast, Reliable Air Duct Cleaning Across Croydon
Air duct cleaning in Croydon typically runs $350 – $650 for a full residential system, and every job starts with a written price before we touch anything. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews serve Croydon from our Philadelphia office. We know the post-WWII ranches along Bristol Pike, the older rowhouses near the Delaware, and the particular headaches that come with ductwork installed around coal chutes in basements from the 1940s. Call us at (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Croydon’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004, and our 365-Day Done Right Promise means if the work fails within a year, we come back and make it right at no charge. That includes a free second visit. Our technicians are background-checked and uniformed, and they arrive inside the quoted window. In Croydon, that matters because we’re often working around tight basement clearances, original sheet-metal ductwork from the 1950s, and the debris pathways that old coal chutes create.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When you’re dealing with musty air after a flood or trying to get documentation for an insurance claim, you need someone to pick up.
We price every job in writing before work starts. The number on the page is the number at the door. No per-vent add-ons, no bait-and-switch. We’ve seen too many Croydon homeowners burned by low teaser quotes that balloon once the truck is in the driveway.
Air Duct Inspection in Croydon
Air Duct Inspection in Croydon means running a camera through your supply and return runs to document what’s actually inside: dust loading, moisture, mold growth, or corrosion from past flooding. Most Croydon homes need this before any cleaning work, especially if they’re near the river or if you smell musty air when the HVAC kicks on. A typical inspection in Croydon runs $150 – $250, and we provide photos and moisture readings you can use for insurance or your own records.
Post-Flood Camera Documentation
After Hurricane Ida in 2021, we saw a wave of Croydon basements take on water. Our camera inspections found mold on trunk interiors and standing water in low return runs that a standard visual check would miss. We document everything with photos, moisture readings, and video footage. That documentation is what gets insurers to pay for replacement when cleaning won’t suffice.
Coal Chute Pathway Assessment
In the older sections near the former Croydon landfill, we regularly find duct runs built around original coal chutes and cleanouts. These act as open pathways for debris and pests. Our inspection maps where these chutes intersect your ductwork so we can seal them properly during cleaning, not just vacuum around them.
Residential Air Duct Cleaning in Croydon
Residential Air Duct Cleaning in Croydon covers the full system: supply ducts, return ducts, trunk lines, and registers, using rotary brush systems and negative-air machines to dislodge and extract debris. A typical full-system cleaning for a Croydon home runs $350 – $650, depending on system size, accessibility, and contamination level. Homes near the river or with post-flood damage may need additional steps.
Source Removal for Older Metal Ductwork
Croydon’s housing stock is dominated by post-WWII single-family homes with original sheet-metal ductwork from the 1940s – 1960s. This metal can corrode after flooding and may harbor decades of heating-oil soot from when oil systems were converted to forced air. We use Rotobrush rotary brush systems and Nikro negative-air machines to perform source removal on salvageable runs, not just surface cleaning.
HEPA-Contained Post-Flood Protocol
When mold is present, we set up negative pressure with HEPA filtration before opening the duct system. This prevents spore release into your living space. Our crew follows The Garrison Code on every job: arrive inside the window, price in writing, complete the work by the book, leave the site clean.
Trusted Brands We Service in Croydon
We clean and service systems with equipment from Rotobrush, Nikro, and Abatement Technologies, and we install filtration products from Honeywell, Aprilaire, and Guardsman. For Croydon homeowners, this means we’re not running to a supplier across state lines when your system needs a specific fitting or filter size. Our Philadelphia office stocks the common parts for post-war duct configurations, so turnaround stays short and the job finishes on schedule.
Common Air Duct Cleaning Problems We See in Croydon Homes
- Heating-oil soot and coal dust buildup. Many Croydon homes were originally heated by oil or coal, and when contractors converted to forced air, they often reused the same ductwork. We regularly clear out decades of accumulated soot and fly ash that newer developments simply don’t have.
- Mold growth after river flooding. The humid Delaware River Valley summers and occasional flooding events like Hurricane Ida can pull moisture and mold spores into ductwork. Standard vacuuming misses spores colonizing porous interior surfaces, which regrow and trigger callbacks.
- Coal chutes acting as debris highways. In riverfront basements, original coal chutes and cleanouts remain visible, and duct runs built around them create open pathways. Cleaning without sealing these chutes means debris and pests re-enter the system within months.
- Corroded sheet-metal from standing water. Original 1940s – 1960s metal ductwork in Croydon can corrode after flooding. Sometimes it’s salvageable with aggressive cleaning; sometimes the metal is too compromised and must be replaced. We document which is which so you’re not paying for work that won’t last.

FAQs About Air Duct Cleaning in Croydon
It depends on what the camera inspection shows. If the metal is intact and mold growth is surface-level, we can perform source removal with HEPA-contained negative pressure and save the ductwork. If the metal is corroded through or mold has penetrated porous interior surfaces, replacement is the only permanent fix. We document both conditions with photos and moisture readings so your insurer can see why we recommended what we did. Call (361) 326-5060 to schedule an inspection.
Croydon’s housing was largely built on former farmland and riverfront industrial land, and many homes were originally heated by oil or coal. When those systems were converted to forced air, contractors often reused the same ductwork without proper cleaning. That means we’re still clearing out heating-oil soot, coal dust, and residual fly ash decades later. This isn’t a failure of your current HVAC system; it’s legacy contamination from the original fuel source.
We provide dated photos, moisture meter readings, and video footage from our camera inspection showing the extent of water intrusion and mold growth. After Hurricane Ida, we used this documentation to help a Croydon homeowner get their insurer to cover partial duct replacement where metal was too corroded to clean. The key is proving that standard cleaning won’t resolve the damage, and that replacement is necessary to prevent future mold regrowth.
Those are original coal chutes and cleanouts from when your home was heated by coal. In Croydon’s older sections, duct runs were often installed around these chutes, and they act as open pathways for debris and pests into your duct system. We inspect for these intersections, seal the chutes during cleaning, and document what we found. Ignoring them means your ducts get re-contaminated after we leave.
Yes. Our post-flood protocol follows NADCA ACR standards for HVAC system restoration, including containment with negative pressure, HEPA filtration, source removal of contaminants, and verification cleaning through post-cleaning inspection. For Croydon’s older metal ductwork, we also assess corrosion and structural integrity beyond the NADCA scope, because 1940s – 1960s sheet metal behaves differently than modern duct board after water exposure. Call (361) 326-5060 to discuss your specific situation.
