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.

Kensington’s homes tell a story that newer suburbs can’t match. The post-WWII ranches along Farmington Avenue, the capes tucked behind the Town Center, the colonials on streets like Percival Avenue – these houses were built when galvanized steel was standard and duct sealing was an afterthought. We’ve cleaned ducts in Kensington since 2004, and the pattern is consistent: decades of accumulation inside original ductwork, combined with mid-century renovations that buried problems rather than fixing them. Our Air Duct Cleaning team arrives with rotary brush systems from Rotobrush and negative-air equipment from Nikro, but the real difference is knowing what to look for in a Kensington basement or crawl space before the first tool gets unpacked.
Why Hollis Air Duct Cleaning Is Kensington’s Preferred Air Duct Cleaning Company
We’re part of the Garrison Partners family, and every Hollis location operates under The Garrison Standard: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. In Kensington, that standard matters more because the work is often more complex than a simple brush-and-vacuum job.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. The price we write down before any work starts does not move at the door. And every job carries our 365-Day Done Right Promise – 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. When you’re trying to schedule around work and family in Kensington, that matters.
We know the local roads – Route 372, Chamberlain Highway, the cut-throughs from Berlin Turnpike – so we plan arrival windows that we can actually keep. And we know the houses: the original 1940s construction near the Town Center, the 1960s ranches with crawl-space duct runs, the split-levels where additions created pressure imbalances that still haven’t been addressed.
Air Duct Inspection in Kensington
Air Duct Inspection in Kensington, CT is where we start every job, because this town’s duct systems often hide problems that standard cleaning alone won’t fix. The inspection runs $150 – $250 when done as a standalone service, or it’s included at no extra charge when you book a full cleaning. We use video cameras to trace every run, looking for crushed branches, disconnected boots, rust perforations in galvanized trunks, and debris accumulation that indicates airflow problems rather than simple dirt.
In Kensington’s post-WWII ranches and capes, many duct systems were run through unheated crawl spaces and basements. Original galvanized steel trunks often rust from the outside before you see any interior debris. We routinely find perforated runs that read as “dirty” but are actually leaking unconditioned, humid crawl-space air into the supply side. This is different from newer metro towns where ducts are sealed inside conditioned chases. The camera finds what a flashlight and mirror cannot.
What We Document
Our technician records video of every trunk and branch, noting rust spots, joint separation, and debris density. You see what we see. If we find a crushed run or disconnected return, we show you the footage and explain the repair before any additional work begins. No surprises. No pressure.
When Kensington Homeowners Need an Inspection
Call for an inspection if your upstairs registers barely move air, if your blower motor runs longer than it used to, if you’ve noticed musty odors in summer or excessive dust in winter, or if your home was built before 1980 and has never had ducts evaluated. These symptoms in Kensington often point to structural duct problems, not just dirty ducts.
Residential Air Duct Cleaning in Kensington
Residential Air Duct Cleaning in Kensington, CT addresses the full supply and return system in single-family homes, which in this town means working with ductwork that’s often 60 – 80 years old. A complete residential cleaning runs $450 – $850 depending on system size, accessibility, and whether we find damage requiring repair. We use a rotary brush system from Rotobrush to agitate debris off duct walls, combined with negative-air collection from Nikro equipment so nothing escapes into your living space.
The heavy oak and maple canopy around Kensington means ducts regularly pull in leaf litter and pollen that standard cleaning can’t fully address. We see compacted organic matter in return drops, especially in homes near the Town Center where mature trees line the streets. Agitation tools matter here. A vacuum hose alone won’t dislodge material that’s been baking through humid summers and drying through heated winters.
Source Removal vs. Surface Cleaning
Source removal means debris leaves your house entirely. We don’t move it from one duct to another. The negative-air machine creates continuous suction at the furnace while the rotary brush works each branch, so dislodged material is captured at the source. For Kensington’s older systems, this method prevents recontamination that lighter cleaning methods can cause.
Sealing and Reconnection Work
Cleaning reveals problems. When we find disconnected boots or crushed runs during a residential job, we explain the repair and provide a written add-on price before proceeding. Reconnecting a return boot typically runs $120 – $200. Sealing a crushed branch with proper materials runs $150 – $300 depending on access. These repairs often improve airflow more than cleaning alone.
Trusted Brands We Service in Kensington
We stock filtration and sealing products from Aprilaire, Abatement Technologies, and Guardsman for Kensington jobs, which means faster turnaround when your system needs components replaced during cleaning. Aprilaire media filters handle the pollen load that Kensington’s tree canopy generates. Abatement Technologies HEPA filtration captures the fine debris that rotary brushing dislodges from older galvanized ducts. Guardsman sealants work on the temperature swings our Connecticut climate produces. We don’t order parts from a warehouse three states away and make you wait. Our van carries what Kensington’s housing stock typically needs.
Common Air Duct Cleaning Problems We See in Kensington Homes
- Rusted-through galvanized trunks in crawl spaces. The humid summers in Kensington promote external rust on ductwork run through unconditioned basements and crawl spaces. Standard negative-pressure cleaning on perforated metal pulls humid crawl-space air into the supply side, making the system dirtier rather than cleaner. We identify these failures with camera inspection before choosing our approach.
- Disconnected or crushed runs from mid-century renovations. Homes near the Town Center often have duct systems with poorly sealed joints from 1960s and 1970s remodeling. We find crushed 6-inch branch runs under new flooring and disconnected return boots that create pressure imbalances. The symptoms look like dirty ducts. The cause is structural damage.
- Compacted leaf litter and pollen in return drops. Kensington’s heavy oak and maple canopy sheds material that enters through exterior vents and gaps in the building envelope. Without proper agitation tools, this organic matter stays compacted in return drops. Source removal requires mechanical brushing, not vacuum suction alone.
- Pressure imbalances from unsealed joints. Original duct sealing in Kensington’s post-WWII housing was often cloth tape or nothing at all. Over decades, thermal expansion and contraction open gaps that leak conditioned air into walls and crawl spaces. The homeowner sees high utility bills and uneven temperatures. The fix is often duct sealing mastic applied after cleaning, not cleaning by itself.

FAQs About Air Duct Cleaning in Kensington
Yes. Original galvanized steel ductwork in Kensington’s post-WWII homes often has external rust and perforations from decades in unheated crawl spaces. A standard cleaning without inspection can pull humid crawl-space air into your supply ducts. We start with camera inspection to identify rusted-through sections, then recommend sealing or replacement alongside source removal. Call (361) 326-5060 to schedule an inspection – estimates are free.
Kensington’s humid summers promote mold growth in ductwork, especially in crawl-space runs where condensation collects on cool metal. Winter heating dries that moisture, releasing accumulated dust and spores into circulation. The seasonal pattern usually points to moisture intrusion through unsealed joints or rust perforations. Camera inspection finds the entry point; sealing and cleaning fixes the symptom at its source. Call (361) 326-5060 for an evaluation.
In Kensington’s mid-century homes, we regularly find crushed branch runs from flooring renovations, disconnected return boots behind finished basements, and rust perforations in galvanized trunks that appear dirty but are actually leaking unconditioned air. We were called to a cape near the Town Center where the second-floor registers were barely moving air and the blower motor was running hot. Using a camera inspection, our tech found a crushed 6-inch branch run under a mid-century renovation’s new flooring and a disconnected return boot; after source removal with agitation tools under negative pressure, we reconnected the boot and sealed the crushed run. Airflow at the registers came back, the blower motor amperage dropped, and the homeowner stopped running the system on “fan-on” to compensate. Call (361) 326-5060 to book an inspection.
Kensington’s heavy oak and maple canopy produces more leaf litter and pollen than neighboring towns with younger landscaping or cleared lots. This organic matter enters through exterior vents and gaps, compacting in return drops over time. Homes near mature trees typically need cleaning every 3 – 5 years rather than the 5 – 7 year standard, especially if the original duct sealing has degraded. Call (361) 326-5060 and we can assess your specific situation.
Yes. Homes near the Town Center often have duct systems with poorly sealed joints from 1960s and 1970s renovations, causing noticeable pressure imbalances that worsen during peak heating and cooling seasons. We identify these with airflow measurement and camera inspection, then seal joints with mastic and reconnect any separated components. The repair typically runs $200 – $500 depending on access and extent. Call (361) 326-5060 for a written quote.
