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.

HVAC Duct Cleaning in Ardmore
HVAC Duct Cleaning in Ardmore means dealing with two completely mechanical eras in the same afternoon: pre-1930 round sheet-metal tied to converted coal furnaces, and post-war trunk-and-branch systems that behave like entirely different animals. The job involves camera inspection first, then agitation with rotary brush systems or negative-air machines depending on duct material, followed by debris extraction under HEPA containment. Most Ardmore homeowners need this when rooms heat unevenly, dust returns quickly after cleaning, or energy bills spike without explanation. A typical full HVAC duct cleaning in Ardmore runs $550 – $850 for older homes with complex runs, $450 – $650 for simpler post-war systems.
Camera Inspection Before Agitation
We run a video inspection before touching anything. In Ardmore’s older homes, we’ve found crushed supply trunks, disconnected second-floor branches, and sections where decades of soot have hardened into a lining no brush can reach. The camera tells us which tools to bring inside, so we’re not guessing with your ductwork.
Sealing What Cleaning Alone Won’t Fix
Cleaning a disconnected duct just means you’ll have clean air leaking into your walls. When our camera finds crushed or separated runs, we seal with duct mastic or mechanical fasteners and test airflow before we leave. The price for sealing work is written down before we start, same as the cleaning.
Vent Cleaning in Ardmore
Vent Cleaning in Ardmore often means something different than in a 1990s subdivision. In Ardmore Park capes, the return path isn’t always a modern wall grille, it’s the original gravity-furnace cold-air chute set into the floor, sometimes with a simple cast-iron register on top. The job involves pulling that register, extracting settled soot and debris the rotary brush can’t reach from above, and checking the boot connection to the trunk below. Supply vent cleaning covers all room registers, the duct boot behind each, and the first few feet of branch line where dust cakes thickest. A typical vent cleaning package in Ardmore runs $180 – $340 for supply registers only, $280 – $480 when we include return chutes and floor boots.
Floor Chute Return Systems
These original cold-air returns collect everything that falls through the register. Toy parts, construction debris from a 1987 kitchen renovation, pet hair compacted into a mat. Our techs pull the register, vacuum the chute with a slender hose, and inspect the boot with a borescope. Skip this step and you’ve left the dirtiest part of the system untouched.
Register and Boot Detailing
We remove every register, clean the grille and the screw slots, and vacuum the boot where it meets the floor or wall. Paint overspray from a long-ago room refresh often cakes the louvers. We don’t just wipe, we restore airflow geometry so air moves the way the original designer intended.
Trusted Brands We Service in Ardmore
Our equipment comes from Rotobrush and Nikro for agitation and negative-air extraction, with HEPA filtration and containment from Abatement Technologies on jobs where asbestos-era materials are present. For homeowners adding filtration after a clean, we stock Honeywell, Aprilaire, and Guardsman media filters with fast turnaround through our Philadelphia supply chain. These aren’t hardware-store tools. A Nikro negative-air machine pulls 2,000 CFM through a HEPA final filter, which is what you need when you’re disturbing eighty-year-old soot in a stone colonial. We explain what each piece does while it’s running, because you should know what’s moving through your home.
Common Air Duct Cleaning Problems We See in Ardmore Homes
- Crushed or disconnected supply trunks in pre-1930 stone colonials. The original round sheet-metal was never designed for forced-air retrofit, and we’ve found sections flattened by decades of foot traffic in unfinished basements or separated at the collar where a 1960s furnace upgrade forced an awkward angle.
- Floor chute returns packed with debris in Ardmore Park capes. The original gravity-furnace cold-air chute sits below a simple register, and without pulling that register, no cleaning tool can reach the compacted soot and household debris that settled over sixty-plus years.
- Heavy organic loading from Ardmore’s mature tree canopy. Norway maples and oaks along older streets drop pollen and mold spores that pull through return grilles all summer, coating duct interiors faster than in less-wooded suburbs like Exton or King of Prussia.
- Township code splits mid-route. Because Lancaster Avenue divides Lower Merion from Haverford Township, crews must switch debris documentation and disposal protocols on the same day, a detail that matters when older Main Line homes may contain asbestos-era duct insulation or transite pipe.
Pricing for Air Duct Cleaning in Ardmore, PA
A full residential air duct cleaning in Ardmore typically costs $450 – $850 depending on system age, duct material, and whether we find crushed or disconnected runs that need sealing. Pre-1930 stone colonials with original round sheet-metal and gravity-furnace remnants run toward the higher end, Ardmore Park capes with short-run trunk-and-branch systems toward the lower. Vent cleaning alone, supply registers and boots only, runs $180 – $340. Add floor chute return cleaning and you’re looking at $280 – $480. We do not price per vent. We price per system, written down before any work starts, and that number does not move at the door. Every estimate is free. Call (361) 326-5060 and we’ll schedule a walk-through.

FAQs About Air Duct Cleaning in Ardmore
Ardmore’s pre-1930 homes use round sheet-metal ducts sized for gravity furnaces, not forced air, so the runs are narrower, the joints are beaded or soldered rather than snap-lock, and eighty years of coal soot may have hardened into a brittle lining that standard rotary brushes can damage. We camera-inspect first, then choose between gentle Rotobrush agitation or Nikro negative-air extraction depending on what we find. Call (361) 326-5060 to schedule an inspection.
Ardmore Park capes have short, accessible trunk-and-branch sheet-metal from the 1940s – 1960s with modern supply grilles, while Main Line stone colonials often retain original gravity-furnace ductwork with floor chute returns and converted coal-fired trunks. The cape cleans faster but may have asbestos-era tape at the joints; the colonial needs camera inspection, HEPA containment, and often sealing of crushed runs. Call (361) 326-5060 and we’ll quote the right scope for your house type.
The Lancaster Avenue line splits Lower Merion Township from Haverford Township, and each municipality has different documentation requirements for construction debris and different disposal site acceptances for materials that may contain asbestos-era insulation. Our crews carry both permit sets and switch protocols mid-route so nothing gets mishandled. This matters on older Main Line homes where original ductwrap or transite boots may be present. Call (361) 326-5060 if your home is near the line.
Ardmore’s mature Norway maples and oaks generate heavier pollen and mold spore loads than newer developments with younger, smaller trees, and the Main Line’s humid summers accelerate organic growth inside duct interiors. Return grilles in older homes sit low on walls or in floors, right where spores settle. We recommend inspection every three to five years in Ardmore versus five to seven in more open suburbs. Call (361) 326-5060 to check your system.
Expect a longer initial inspection with video, HEPA-contained extraction equipment, and possible discovery of crushed or disconnected runs that need sealing before cleaning will improve airflow. Last month on a 1922 stone colonial just off Lancaster Avenue, our techs ran a camera inspection and found the original gravity-furnace supply trunk had three crushed runs and a disconnected branch feeding the second floor. We set up negative pressure with HEPA filtration, used Rotobrush agitation tools to pull decades of settled soot from the round sheet-metal, then sealed the crushed sections and reconnected the branch, the homeowner said the upstairs finally heated evenly for the first time in years. The price for all work was written down before we started. Call (361) 326-5060 for a free estimate on your system.
