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 North Tonawanda’s Preferred Air Duct Cleaning Company
North Tonawanda homeowners call us because we’ve earned a reputation for showing up inside the quoted window, pricing the job in writing before we touch anything, and leaving the site clean. Our background-checked, uniformed technicians follow The Garrison Code on every job: arrive squared away, explain what the equipment does in plain terms, and stand behind the work with our 365-Day Done Right Promise. If anything fails within a year, we come back 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. That discipline matters in a city where too many homeowners have watched a low teaser price balloon once the van was in the driveway.
We understand North Tonawanda’s housing stock because we work it every week. The late-19th and early-20th-century doubles, four-squares, and worker cottages built for lumber, paper, and chemical mill workers don’t present the same ductwork you’ll find in Amherst’s post-war subdivisions or Kenmore’s mid-century ranches. Most of these homes weren’t built with forced air at all. The ductwork we clean was retrofitted into gravity-furnace chases, which is why return runs here so often dead-end in a wall cavity instead of reaching the air handler. That retrofit pattern is what makes coal ash and mill-era soot deposits show up in North Tonawanda returns rather than in neighboring systems of the same era.
Air Duct Inspection in North Tonawanda
Air Duct Inspection in North Tonawanda is where every job should start, because the visible registers almost never tell the real story in a pre-1920 home. Our inspection runs a camera through the supply and return trunks, checks for disconnected runs in gravity-conversion chases, and maps rust-through at duct joints from decades of canal-side basement humidity. A typical inspection in North Tonawanda costs $125 – $195 and includes a written report with photo documentation. We recommend it before any cleaning or sealing work, and we require it when we suspect crushed lines or deteriorated insulation.
What We Find in Older Returns
Camera inspection of return trunks in Oliver Street and Niagara Street homes regularly reveals coal ash and plaster grit packed into retrofit chases that were never designed as ductwork. These deposits don’t move with a standard brush pass. We document them, explain what we’re seeing, and price the remediation before any work starts.
Rust-Through and Joint Failure
Basements along the Erie Canal corridor hold humidity year-round. We inspect for rust-through at galvanized seams and deterioration of asbestos-wrapped or uninsulated trunk lines. Sealing over damaged metal traps moisture and accelerates failure. We flag it in writing.
Residential Air Duct Cleaning in North Tonawanda
Residential Air Duct Cleaning in North Tonawanda is less about modern HVAC maintenance and more about remediation of legacy industrial-era buildup. Our crews use Rotobrush rotary brush systems and Nikro negative-air machines with HEPA filtration to agitate and extract debris from supply and return ducts without blowing it back into your living space. A typical residential cleaning in North Tonawanda runs $350 – $650 for a full system, depending on the number of runs, accessibility, and whether we find disconnected or crushed lines that need reconnection. Every job gets a written price before work begins.
The Negative-Air Method
We set negative pressure at the air handler and seal each register. This creates suction through the entire system while rotary brushes knock debris loose. On North Tonawanda’s old sheet-metal ductwork with visible seams, negative pressure is non-negotiable. Without it, agitation blows a century of plaster debris and mill-era particulate back through the living space instead of removing it.
Sealing as the Actual Fix
Cleaning removes what’s loose. Sealing with duct mastic addresses the gaps that let it accumulate. In North Tonawanda’s uninsulated galvanized trunk lines, we often find seam separation and rust-through that cleaning alone won’t solve. We price sealing separately, in writing, and we never seal over deteriorated metal without flagging it first.
Trusted Brands We Service in North Tonawanda
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and filtration products from Aprilaire, Abatement Technologies, and Guardsman. These are the same tools commercial crews use, not hardware-store gear. For North Tonawanda homeowners, that means we can source replacement components and filtration media without the delays that slow down smaller outfits. When we recommend an Aprilaire media filter or a Guardsman UV treatment after cleaning, it’s because we’ve matched the product to the actual condition of your ductwork, not because it’s on a sales sheet.
Common Air Duct Cleaning Problems We See in North Tonawanda Homes
- Coal ash and mill-era soot in return trunks. Homes along Oliver Street and Niagara Street regularly show black, greasy deposits in returns that dead-end in wall cavities. This isn’t household dust. It’s legacy particulate from the city’s industrial era, and it requires negative-air extraction with HEPA filtration, not a shop vacuum.
- Crushed or disconnected retrofit runs. Gravity-furnace chases converted to forced-air ductwork often have trunk lines crushed by later renovations or branches that were never properly connected. We find these with camera inspection and reconnect them as part of the cleaning scope, priced in writing.
- Rust-through at canal-side duct joints. Basements near the Erie Canal and Niagara River hold humidity that eats galvanized seams over decades. We inspect for this before sealing, because mastic over rusted metal is a temporary fix that traps moisture.
- Mold and mildew in summer-damp air handlers. Western New York’s humid summers and cool basements create condensation at the air handler. We check the plenum and coil cabinet during every inspection, and we recommend cleaning and treatment when we find biological growth.
Pricing for Air Duct Cleaning in North Tonawanda, NY
A full residential duct cleaning in North Tonawanda typically runs $350 – $650. That covers the standard supply and return system in a two- to three-bedroom home with accessible basement trunk lines. Larger homes, additional branches to finished attics or additions, or remediation of crushed and disconnected runs move the price toward the upper end. Commercial systems start around $800 and scale with square footage and HVAC complexity.
What affects your price: the number of supply and return registers, accessibility of trunk lines (many North Tonawanda basements are tight), whether we find disconnected runs that need reconnection, and whether sealing is required after cleaning. We do not quote per-vent pricing. We do not bait with a low coupon and add charges at the door. The price is written down before any work starts, and it does not move.
Call (361) 326-5060 for a free written estimate. We’ll ask about your home’s age, square footage, and any symptoms you’ve noticed, then give you a range you can plan around.

FAQs About Air Duct Cleaning in North Tonawanda
Most North Tonawanda homes built before 1920 weren’t designed for forced air. The ductwork was retrofitted into gravity-furnace chases, so returns often dead-end in wall cavities and supply trunks follow paths that wouldn’t meet modern codes. Amherst’s post-war ranches were built with engineered duct systems from day one. The retrofit pattern in North Tonawanda is why we find coal ash and mill-era soot in returns here, not in Amherst systems of the same era. Call (361) 326-5060 and we’ll explain what your specific setup looks like on camera.
Yes, and we find it regularly. A crew working a four-square off Oliver Street pulled a return register and found the run choked with coal ash and plaster grit, with a crushed trunk line feeding a second-floor branch and rust-through at the joint where decades of canal-side basement humidity had eaten the seams. We set negative pressure at the air handler, ran agitation tools through the supply and return ducts, HEPA-filtered the exhaust, then sealed and reconnected the crushed run. The homeowner’s furnace stopped short-cycling and the second-floor registers finally moved air for the first time in years. Camera inspection finds this before we quote, not after.
In North Tonawanda’s pre-1920 homes, probably not. Normal household dust is gray and fibrous. The black, greasy deposits we pull from return trunks in the Oliver Street and Niagara Street corridors are typically coal ash and mill-era soot that settled into retrofit chases during the city’s industrial period. Your furnace stirs it up every heating season. It requires mechanical agitation and negative-air extraction, not a better furnace filter. Call (361) 326-5060 for an inspection and we’ll show you what you’re dealing with.
Musty basements in North Tonawanda often indicate mold or mildew at the air handler plenum or coil cabinet, especially in canal-adjacent homes where summer humidity runs high. Duct cleaning addresses the distribution system, but if the source is a damp evaporator cabinet or standing water in the condensate pan, cleaning alone won’t solve the smell. Our inspection checks both. We price cleaning and treatment separately, in writing, so you know exactly what you’re paying for.
Sealing is priced and performed as a separate scope, though we often recommend it after cleaning North Tonawanda’s old galvanized trunk lines. Cleaning removes loose debris. Sealing with duct mastic addresses the seam gaps and rust-through that let it accumulate. We never seal over deteriorated metal without flagging it in the inspection report. The price for sealing is written down before any work starts, just like the cleaning. Call (361) 326-5060 and we’ll walk through whether your system needs one, the other, or both.
