Our Air Duct Cleaning Services in Kensington
Residential Duct Cleaning
Most Kensington homes are two- or three-story attached brick row houses built between 1910 and 1940, originally heated by steam radiators with no ductwork at all. Where forced-air systems exist, they’re mid-century or later retrofits threaded through spaces never engineered for HVAC. Our Air Duct Cleaning team cleans these non-standard systems with segmented protocols, sealing off each zone to prevent debris from circulating through the house. A typical residential duct cleaning in Kensington runs $350-$650 depending on system complexity and accessibility.
Commercial Duct Cleaning
Kensington’s commercial spaces, many converted from original residential row houses, present their own challenges. Mixed-use buildings along Cortelyou Road with retail below and apartments above often share duct infrastructure that predates current code. We clean these systems with full documentation for property managers and co-op boards, working around tenant schedules to minimize disruption. Commercial jobs in Kensington typically start at $550 and scale with system size.
Supply Duct Cleaning
Supply ducts in Kensington’s converted row houses frequently cross what are now legally separate apartments, a situation standard cleaning protocols rarely account for. We map each supply run before cleaning, identify boundary crossings, and obtain proper access or install isolation dampers where needed. Supply duct cleaning as a standalone service in Kensington generally runs $200-$400.
Return Duct Cleaning
Return ducts in retrofit systems often suffer from the sharpest turns and most restricted access, particularly where they’re routed through original closets or dropped ceilings. Our Rotobrush and Nikro equipment handles tight radius bends that standard tools abandon, and our video inspection confirms we’ve reached the full length of each return. Standalone return duct cleaning in Kensington typically costs $180-$350.
Full System Cleaning
For Kensington homeowners who want the complete job, our Full System Cleaning covers supply trunks, return plenums, branch lines, and the air handler cabinet. This is the service we recommend for first-time cleans in older homes, where decades of accumulated debris won’t be addressed by partial cleaning. Full system cleans in Kensington run $550-$850, with most completed in a single day.
Video Inspection
Every job we perform includes camera inspection before and after cleaning, using equipment from Abatement Technologies and Honeywell. In Kensington’s retrofit systems, this isn’t optional documentation, it’s essential diagnosis. We’ve found disconnected sections, collapsed flexible duct, and even old galvanized lines rusted through, all hidden behind finished surfaces. The video record shows you exactly what we’re addressing and confirms the work is complete.

Trusted Brands We Service in Kensington
We stock parts and cleaning equipment from Rotobrush, Nikro, Abatement Technologies, Honeywell, and Aprilaire, the same brands serious HVAC contractors specify for demanding applications. For Kensington homeowners with older systems, this matters because retrofit ductwork often uses non-standard fittings that discount operators can’t source. We carry adapters and transition pieces for galvanized-to-flexible connections common in Brooklyn’s converted housing stock, so repairs don’t turn into multi-day waits. When we find a disconnected section during your cleaning, we can often fix it then, not schedule a return visit.
Common Air Duct Cleaning Problems We See in Kensington Homes
- Subdivided apartment duct crossings. Technicians trained on suburban single-family homes routinely assume one supply trunk serves one household. In Kensington’s converted row houses, that trunk may now cross two or three legal units, and cleaning without proper isolation contaminates neighboring apartments or violates access agreements.
- Sharp turns and blocked sections in retrofit ductwork. Ducts routed through closets, dropped ceilings, and party-wall cavities include bends and restrictions that standard cleaning tools can’t navigate. The debris remains after the service, and airflow stays compromised.
- Accelerated recontamination from Coney Island Avenue traffic. Kensington’s location along this dense commercial corridor exposes homes to elevated diesel particulates and urban soot. Low-filtration retrofit systems, never designed for air conditioning, pull this contamination indoors and recirculate it through the house.
- Technicians underestimating system complexity. A standard residential cleaning protocol assumes accessible registers, straight trunk lines, and modern flexible duct. Kensington’s housing stock violates all three assumptions, and crews without local experience leave significant portions of the system untouched.

FAQs - Air Duct Cleaning in Kensington
Yes, in most cases we can clean your ducts without entering adjacent units by using segmented isolation techniques and installing temporary dampers at boundary crossings. We serviced a three-family conversion on Stratford Road where the original 1930s row house had its supply duct split across two apartments, with the main trunk running through a shared dropped ceiling. Our crew performed a segmented cleaning, sealing off each unit’s section to prevent cross-contamination, and replaced a disconnected section of 40-year-old galvanized duct with modern flexible ductwork. Call (833) 348-8789 to discuss your specific layout, estimates are free.
Yes, we clean and inspect new duct installations in Kensington’s older homes, and we strongly recommend video inspection before your new system goes into service. Retrofit ductwork in row houses often has installation debris, sharp edges, and access panels left open, all of which should be addressed before you start running conditioned air. A pre-occupancy clean for a new forced-air retrofit in Kensington typically runs $400-$700 depending on system size. Call (833) 348-8789 to schedule.
Your Kensington home’s ductwork is a retrofit, not original construction. These row houses were built with steam or hot-water heat and no ductwork at all; any central air system was added decades later by threading ducts through closets, dropped ceilings, and party-wall cavities never designed for HVAC. The sharp turns and restricted spaces are structural compromises, not design choices, and they require specialized cleaning equipment and techniques. Our Rotobrush and Nikro tools handle radius bends that standard equipment abandons. Call (833) 348-8789 for an inspection if you’re unsure whether your system has been fully cleaned.
Yes, homes along the Coney Island Avenue corridor experience measurably faster duct contamination than interior blocks due to elevated diesel particulates and urban soot from heavy commercial traffic. Brooklyn’s humid summers compound this by pushing constant central-AC use through low-filtration retrofit systems that were never designed for it. For Kensington homes on major corridors, we recommend inspection every two to three years rather than the standard three to five, and we can upgrade your filtration during cleaning. Call (833) 348-8789 to discuss filtration options with your next service.
Yes, we regularly clean century-old ductwork in Kensington homes, but we assess condition with video inspection first and adjust our cleaning pressure and tool selection to match. Old galvanized steel can be thin and corroded; original asbestos duct lining, if present, requires modified protocols. We don’t force tools through fragile sections or pretend old material is new. If we find damage that makes cleaning inadvisable, we’ll show you on camera and discuss repair or replacement options with upfront pricing. Call (833) 348-8789 for a careful evaluation, estimates are free.
