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 Cardinal Air Duct Cleaning Is Kensington’s Preferred HVAC Cleaning Company
Most of the homes we clean in Kensington were built between 1950 and 1975, and their ductwork shows it. We know the ranch layouts, the split-levels with shared return plenums, and the way galvanized steel ducts in this housing stock collect rust scale that flex duct simply doesn’t. That local knowledge means we don’t waste your time running a brush through supply vents when the real problem is downstream of the air handler. Our techs arrive in uniform, background-checked, and you’ll know their name before they ring the bell. Every job comes with a live arrival window you can track from your phone, a written price before any work starts, and before-and-after photos of your own ducts when we’re done. We’re part of the Relay Home Co. family, founded 2005, and we operate under Kensington‘s expectations for straight answers and straight pricing.
AC Vent Cleaning in Kensington
Our Air Duct Cleaning in Kensington starts with AC vent cleaning, the job most homeowners call about first because it’s the visible part of the system. Dust and pet hair collect on the supply registers in a matter of months, especially in homes along Southington Road and around the northern end of town where tree cover is heavier. But here’s what a real AC vent cleaning actually involves in Kensington, CT: the registers are pulled, agitation tools loosen the buildup along the supply trunk, and a negative-pressure vacuum running HEPA filtration at the truck pulls everything back to the source rather than stirring it into the room. On 1950s and 60s ranch layouts, that means cleaning the full supply path, not just brushing the face of the register.
Supply Register and Boot Cleaning
The register boot is where air leaves the duct and enters the room. In older Kensington homes, this is also where dust, skin cells, and insects accumulate fastest because the galvanized metal is rougher than newer materials. We pull each register, inspect the boot with a camera, and clean the full transition back to the trunk line.
Return Air Path Cleaning
The return side often carries five times the debris of the supply side, because it pulls unfiltered air from the house. We pull return grilles, remove the collected matting, and follow the path back to the air handler. If your return plenum is shared, as many Kensington split-levels have, this is where the real buildup hides.
Furnace Duct Cleaning in Kensington
Furnace duct cleaning in Kensington homes means going after what winters leave behind: rust scale, soot from the burner, and the fine dust that settles through supply and return ducts all heating season. Homes with older galvanized trunks off Kensington Road and around High Road frequently show rust flaking on interior duct walls, which then rides the airstream and deposits on registers and furniture. A furnace duct cleaning here needs to account for that. We run professional-grade agitation tools through the full duct run, with negative-pressure extraction pulling loosened material back to a HEPA-filtered vacuum at the source, not into your living room.
Heat Exchanger and Plenum Cleaning
The plenum is the box where ducts meet the furnace. In older Kensington furnaces, the heat exchanger area collects a fine soot film and the plenum traps whatever the previous filter let through. Cleaning this section properly extends the life of the blower and improves airflow across the whole system.
Coil Treatment and Air Handler Interior
If your Kensington home has central air stacked on the furnace, the evaporator coil sits right in the airstream. Dirty coils make the system work harder and blow warmer air in August. We clean the coil, the blower wheel, and the air handler interior, then apply a coil treatment that slows future buildup.
Trusted Brands We Service in Kensington
We service and clean systems built around every major residential brand you’ll find in Kensington, including Honeywell filtration, Aprilaire whole-house media filters, and Abatement Technologies containment units where the job calls for it. Our trucks carry the common parts and filters for most standard residential setups, so we’re not making a second trip across the Berlin Turnpike for a filter you should have had replaced months ago. If your system runs a Nikro-compatible access port or an Aprilaire filter housing, we’ll document the condition with photos and tell you honestly whether replacement is due or can wait. Fast turnaround for Kensington customers means we keep our vans stocked for the systems we actually see in this town’s homes.
Common HVAC Cleaning Problems We See in Kensington Homes
- Rust scale in original galvanized ducts: The 1950s and 60s ranches off Farmington Avenue and around Kensington Road often still run their original steel ducts. Interior rust flakes off over time, coats the blower wheel, and shows up as orange dust on registers.
- Lint and dust loading on the return side: Because return air bypasses the filter in many older Kensington floor plans, dust and fiber collect on the return trunk and the blower housing. Supply vents look fine, but the system is still pushing dirty air.
- Filter housing air gaps: A surprising number of homes in Kensington have a filter that doesn’t seal. Air flows around the filter instead of through it. That means the coil and blower get coated even when filters are changed on schedule.
- Blower wheels caked with condensation debris: Kensington’s humid summers cause condensation in the air handler, and dust binds to it. By fall, the blower wheel is off-balance and noisier than it should be, and airflow is down across every room.
Pricing for HVAC Cleaning in Kensington, CT
A full HVAC cleaning in Kensington typically runs $425 – $780, depending on the number of systems and the amount of buildup. A straightforward single-furnace home with accessible ductwork falls at the lower end. A split-level with two systems, a shared return plenum, and heavy rust or pet-hair loading lands at the upper end. AC vent cleaning on its own runs $180 – $340, and furnace duct cleaning on its own typically falls between $275 and $540. The price is written before we start, it’s one flat price per system, and it doesn’t change at the door. What you’ll never see from us: a per-vent quote, or a teaser price that grows once we’re inside. Call (737) 727-2314 for a free estimate on your specific Kensington home.
We were out on a ranch off Kensington Road where the homeowner believed the system just needed a quick vent brushing. Our camera inspection showed rust scale and a lint pathway loading up the return side downstream of the air handler. We set up negative pressure with HEPA filtration at the truck, ran agitation tools through the supply and return ducts, and pulled the buildup back to the source. The before-and-after photos of their own ducts were what closed the job, one flat price per system, agreed before we started.

FAQs About HVAC Cleaning in Kensington
A Kensington home typically needs HVAC Cleaning in Kensington every 3-5 years, but homes with pets, smokers, recent renovations, or 50-year-old galvanized ducts often need attention sooner. If you haven’t had it done in five years or you’re seeing dust settle within days of cleaning, it’s time. Call (737) 727-2314 and we’ll help you figure out whether cleaning is genuinely needed or can wait, we’d rather tell you to hold off than sell you a job that isn’t necessary.
We charge one flat price per system, never per vent. Per-vent pricing punishes homes with older custom layouts where the vent count says nothing about how much duct actually needs cleaning. In Kensington’s ranch and split-level homes, that’s most of them. Your written price is agreed before the work starts and it doesn’t change.
We inspect with a camera, set up negative-pressure extraction with HEPA filtration at the truck, run agitation tools through supply and return ducts, clean the blower, coil, and air handler, and then show you before-and-after photos of your own ducts. The whole job runs 3-5 hours for a typical Kensington home. If the work isn’t right within 365 days, we return and correct it at no charge, that’s the 365-Day Done Right Promise.
Yes, every job includes before-and-after photos of your own ductwork.
