Why Cardinal Air Duct Cleaning Is Kensington’s Preferred Air Duct Cleaning Company

Kensington homeowners keep calling us back because we do something most duct cleaners in the area don’t: we show you your ducts. Before we clean, we run a video inspection camera through the supply and return runs so you see what’s actually in there. After we finish, you get the same view, clean. No mystery, no “trust us.” The majority of our Kensington work comes from referrals along the Arlington Avenue corridor and up in the Kensington Park neighborhood because the before-and-after difference is impossible to argue with.

Our techs know the difference between the 1920s bungalows near Colusa Circle and the 1950s ranchers spreading up the hillside. That matters because a 1940s gravity-furnace house with unlined return chases has different duct problems than a newer forced-air home. We stock the parts and tools to handle both without slowing down. When you book with us, you get a live arrival window you can track from your phone, a written price before any work begins, and the name of your technician before they ring the doorbell. That’s the Relay Standard, our parent company’s non-negotiable operating rule since 2005, and it’s how every Air Duct Cleaning job runs.

Air Duct Inspection in Kensington

Air Duct Inspection in Kensington is the first step we recommend for any home that hasn’t had its ducts looked at in five years or more. We run a camera through the supply and return ducts, check the air handler, and look at the blower motor and evaporator coil if accessible. Homes around Kensington Park Road and the older tracts near the Arlington border often have ducts that were sized for gravity heat, not forced air, and only a camera shows what’s happening in the low-velocity runs that never self-clear.

When an inspection makes sense first

If you’ve bought an older Kensington home and don’t know when the ducts were last touched, start with an inspection. The camera feed shows dust, debris, mold, or just normal accumulation before you commit to a full cleaning. Some homes we inspect don’t need cleaning yet, and we’ll tell you that plainly.

What the inspection covers

Beyond the visual, we check airflow velocity at key registers, look for disconnected or crushed runs, and note any rust or moisture that shouldn’t be there. You get a summary of what we found and a flat price for any cleaning you decide to move forward with.

Residential Air Duct Cleaning in Kensington

Residential Air Duct Cleaning in Kensington homes is the service we do most often, and it always follows the same structure: negative-pressure extraction with HEPA filtration, rotary agitation through each branch run, and a final camera pass so you see the result. For a typical three-bedroom Kensington home, expect the whole job to take about 3 – 4 hours and cost between $500 and $800. The price is agreed before we start and doesn’t move, no matter what the camera finds inside.

The cleaning process that actually removes debris

We don’t blow compressed air through your registers and call it done. We seal the system under negative pressure, meaning the loosened debris goes straight into the vacuum, not back into your living room. Rotobrush agitation whips the duct walls free of the felt-like lint and dust that builds over decades, and Nikro HEPA units capture what comes out.

Flat per-system pricing, always

You’ll never see per-vent pricing from us. Kensington’s older homes have irregular, historically added floor and wall vents, which makes per-vent pricing a bad deal for you. One flat price per system, written down before we touch a single duct. If the camera reveals something the estimate didn’t cover, the price still doesn’t change. That’s the whole point.

Trusted Brands We Service in Kensington

We work on systems from every major manufacturer, and when a Kensington home needs filtration or air quality components, we stock and install Aprilaire media filters, Rotobrush rotary brush systems for cleaning, and Guardsman filtration products. If your system uses an Abatement Technologies containment approach or standard Honeywell air cleaner, we’re familiar with it and can service it in place. Most parts for common setups are on our trucks when we arrive, which means fewer follow-up visits. Call (737) 727-2314 and tell us the make and model of your furnace; we’ll bring what you need.

Common Air Duct Cleaning Problems We See in Kensington Homes

• Original gravity furnace returns packed with decades of lint. Many Kensington homes from the 1920s – 1950s still have their original octopus gravity furnaces, and the unlined return chases were never sized for forced air. The low-velocity runs collect a dense felt of lint, pet hair, and dust that a standard vacuum pass never reaches.
• High-velocity dust on the hillside homes. The Kensington Park hills catch more wind than flatland Kensington, and that extra airflow through older window and door seals pulls more airborne dust into the return. Homes up the hill often need returns cleaned more often than houses in the flats.
• Blower and coil contamination after a cheap cleaning. We follow behind other companies regularly because someone cleaned the ducts but skipped the air handler and blower motor. Lint pushed out of the supply runs resettles on the blower wheel and evaporator coil within weeks, and the homeowner is back where they started.
• Disconnected or crushed branch runs from old remodel work. Kensington basements and crawlspaces have seen decades of plumbing, electrical, and remodel work. It’s common to find a flex run that’s been knocked loose or crushed under a house. Our camera inspection catches those before you pay for a cleaning that won’t reach those rooms.
