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.
Fast, Reliable Air Duct Cleaning Across Philadelphia
Air duct cleaning in Philadelphia typically runs $400 – $800 for a residential system and $900 – $2,500 for commercial setups, with most jobs completed in a single visit. We’re Hollis Air Duct Cleaning, and our Philadelphia office coordinates crews who know the difference between a standard suburban ranch and a 1920s rowhouse with a full-height party-wall return. Call (361) 326-5060 for a free estimate.
We’ve been working in Philadelphia since 2004, and the housing stock here is unlike anywhere else in the country. Narrow rowhouses in Kensington, Fishtown, and South Philly carry retrofitted HVAC systems through masonry walls that are 100 years old or more. Short duct runs, original gravity ducts, and uninsulated metal in damp basements are the norm, not the exception. That’s why Duct Sealing in Philadelphia is often needed before cleaning can even begin. That matters because a crew trained on suburban split-levels will price your job wrong and miss half the system.
Our technicians arrive uniformed, background-checked, and equipped with Rotobrush rotary systems and Nikro negative-air machines. The price is written down before we touch anything. No per-vent add-ons, no surprise charges at the door.
Why Hollis Air Duct Cleaning Is Philadelphia’s Preferred Air Duct Cleaning Company
Philadelphia homeowners have seen the bait-and-switch. A coupon promises $99 whole-house cleaning, then the technician finds “extra vents,” “deeper sanitizing,” or “mold remediation” that triples the bill. We don’t work that way. Our Air Duct Cleaning team gives one flat price per system, agreed in writing before the van doors open.
The Garrison Standard governs every Hollis location, including ours here in Philadelphia. That means arriving inside the quoted window, pricing in writing, completing the job by the book, and leaving the site clean. Our 365-Day Done Right Promise covers every job in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit.
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 call (361) 326-5060, you talk to someone who can book your appointment.
We know the local conditions. Humid subtropical summers in Philadelphia drive condensation into unconditioned duct spaces, while winter heating stirs up accumulated dust. Rowhouses along East Passyunk or in Queen Village have quirks that surprise out-of-town contractors. Our crews don’t get surprised.
Ductwork Cleaning in Philadelphia
Ductwork Cleaning in Philadelphia is rarely a standard service call because the city’s housing stock demands a custom approach on nearly every job. The work involves source removal: we attach a negative-air machine to your trunk line, seal the registers, and use mechanical agitation to dislodge debris so it gets carried out of your home through HEPA filtration, not pushed into your living space. In Philadelphia’s pre-1950 rowhouses, this process must account for unlined original ducts, asbestos-wrapped runs in basements, and those hidden party-wall returns that connect multiple floors.
A typical residential Ductwork Cleaning in Philadelphia runs $400 – $800 per system. Homes with multiple HVAC zones, common in larger Center City conversions or expanded rowhouses, get priced per system so you’re not paying for equipment that isn’t there or getting shorted on equipment that is.
When Philadelphia Homes Need It
Most Philadelphia homeowners schedule duct cleaning every 3 – 5 years, but the city’s conditions accelerate that timeline. Humid summers breed mold in uninsulated basement runs. Winter heating cycles blast dry air through dust-packed ducts. If you smell mustiness when the AC kicks on in July, or if your 1920s Kensington rowhouse has never had the original gravity ducts touched, you’re past due.
What the Process Looks Like
We start with a visual assessment of your air handler and accessible trunk lines. Then we seal the system, establish negative pressure, and run agitation tools through each supply and return branch. In Philadelphia rowhouses with short, irregular retrofitted runs, we camera-inspect first. Collapsed or disconnected original ducts are common; finding them before we start saves both of us from a failed job.
Air Duct Inspection in Philadelphia
Air Duct Inspection in Philadelphia should precede every cleaning job in this market, and it is especially critical given the age and variety of ductwork hidden in local homes. We use video inspection cameras to document the interior condition of your ducts before we quote, showing you exactly what we’re dealing with: accumulated debris, disconnected runs, pest intrusion, or mold growth. An Air Duct Inspection in Philadelphia typically costs $150 – $300 as a standalone service, though we often roll it into the cleaning price once you see what the camera finds.
The inspection protects both of us. You see the problem with your own eyes. We see the full scope so we can price accurately and avoid the “we found more than we expected” conversation that erodes trust in this trade.
Camera Documentation
Our video inspection records the full length of accessible ductwork. In Philadelphia rowhouses, that means checking whether your return is a standard basement trunk or one of those full-height party-wall chases that serves every floor. We save the footage and share it with you. After cleaning, we can re-run the camera to verify the results.
What We Find in Local Homes
Disconnected flex duct behind a drywall patch. Asbestos-wrapped metal in a Fairmount basement. A squirrel nest in a Germantown return. Mold blooming on unlined duct in a humid Manayunk crawlspace. Philadelphia’s housing stock generates specific, predictable problems that generic inspection checklists miss.
Trusted Brands We Service in Philadelphia
We clean and service ductwork connected to all major HVAC brands, and we offer Philadelphia Carrier service among others. We stock filtration products from Honeywell, Aprilaire, and Guardsman for Philadelphia customers who want to upgrade after their system is clean. Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines for source removal. These are the same tools commercial crews use in hospitals and schools, not hardware-store vacuums with a longer hose. If your system needs new filters or upgraded media after cleaning, we carry the right size and spec for your unit. Fast turnaround, no waiting on shipped parts.
Common Air Duct Cleaning Problems We See in Philadelphia Homes
- Full-height party-wall returns in South Philly rowhouses. A single return duct runs vertically through the shared masonry wall, feeding every floor. When it’s blocked with decades of dust, no individual room register cleaning will fix the starvation on upper floors. The whole chase must be accessed and cleared.
- Condensation-driven mold in unconditioned basement and crawlspace ducts. Philadelphia’s humid summers push moisture into cool metal ducts running through warm, unventilated spaces. The result is black mold that blows spores into living areas every time the AC cycles. Negative-pressure cleaning with HEPA capture is the only safe removal method; spraying chemicals into the duct just kills the surface and leaves the colony.
- Collapsed or disconnected original gravity ducts in Kensington and Fishtown. Retrofitted forced-air systems often reuse or bypass original gravity ductwork that was never designed for the pressure. A Rotobrush sent blindly down a collapsed run accomplishes nothing and can damage your system further. Camera inspection first. Always.
- Pest intrusion through unsealed masonry and unlined metal. Old mortar, missing cleanout covers, and gaps where ducts pass through foundation walls give rodents and insects direct access. We find droppings, nesting material, and chewed flex duct regularly in century-old Philadelphia basements. Source removal gets the debris out; sealing the entry points keeps it from returning.

FAQs About Air Duct Cleaning in Philadelphia
Because your rowhouse probably has a hidden full-height party-wall return, retrofitted short runs, or original gravity ducts that a suburban crew has never encountered. We inspect first, then price per system in writing. Call (361) 326-5060 for a free estimate.
We access it through the original return grille, establish negative pressure at the air handler, and run agitation tools down the full-height chase while capturing debris through HEPA filtration. Our tech was called to a three-story rowhouse off East Passyunk where the second and third floors wouldn’t cool; pulling that original grille revealed a century of packed dust. After source removal on supply and return ducts, all three floors pulled air again.
We can clean around them if the wrap is intact and undisturbed, but we do not disturb friable asbestos. If the wrap is damaged, we stop and recommend a licensed asbestos abatement contractor before proceeding. We flag this during our initial inspection and document the condition with photos for your records.
Philadelphia’s combination of 100+ year old masonry walls, humid subtropical summers, and cold winters creates condensation cycles that newer, insulated, climate-controlled construction simply doesn’t experience. Unlined metal ducts in unheated crawlspaces sweat all summer. Gaps in century-old foundations invite pests. Sun Belt subdivisions built in the 1990s with sealed attics and flex duct don’t face these conditions at this scale.
You get before-and-after video from our camera inspection, a written invoice with the exact scope of work performed, and our 365-Day Done Right Promise in writing. If we cleaned your party-wall return, the after video shows the cleared chase. If we found and reported a disconnected duct, the photos are in your file. You paid for work you cannot see; we document what was done so you know it happened.
