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.

AfterAir Duct Cleaning Before & After in Denver, CO
We’ve photographed the inside of every duct run on every job since 2013. Not marketing shots - documentation. Here is what we actually found, what the equipment recorded, and what the customer received in their standard job record. No staging, no exceptions.
Recent Transformations
Heavy Debris Build-Up in Stapleton Return Duct
The camera showed a 2-inch layer of compacted debris where the return duct met the plenum (the main distribution box, where all ducts connect). This is common in Stapleton homes built during the 2000s construction surge - the original flex duct sags at the plenum collar, creating a debris trap that standard register vacuums never reach. Our crew used negative-pressure extraction (a sealed vacuum system that pulls debris backward through the entire run) with a Rotobrush mechanical agitator to break the compacted layer loose. The photo record showed bare metal at completion. Written price before work started: $320 for the full system. Customer received 14 before-and-after images as part of the standard job record.
Post-Renovation Dust Load in Berkeley Kitchen Supply Run
A Berkeley homeowner called after a kitchen remodel left fine dust blowing from the supply register every time the HVAC cycled. The camera showed a uniform coating of silica dust on the duct walls - the kind of particulate that bypasses standard furnace filters and recirculates for months. We sealed the register, applied negative-pressure extraction with a Nikro HEPA-filtered collector, and ran a post-service airflow verification. The written scope specified three supply runs and two returns affected by the renovation zone. Price agreed before any panel came off: $285. The photo record included a timestamped airflow meter reading.
Pet Dander Accumulation in Congress Park Older Home
The return duct in a 1920s Congress Park bungalow showed gray matting that the camera identified as compressed pet dander and hair - the homeowner had run a grooming business from the basement for two years. This material doesn’t respond to standard vacuuming because it adheres to galvanized steel through electrostatic bonding. We used mechanical agitation with an Abatement Technologies brush system followed by negative-pressure extraction. The crew noted in the job record that the original duct was unlined galvanized steel, common in pre-1950 Denver construction, which requires lower brush RPM to avoid damaging the seam joints. Written price: $295 for the full system. The 365-Day Done Right Promise applied in writing.
Mold-Prone Flex Duct in Cherry Hills Village Crawl Space
A Cherry Hills Village homeowner reported a musty odor when the AC ran in July. The camera found organic growth at the low point of a flex duct run in the crawl space - Denver’s clay-heavy soils create persistent moisture in crawl spaces, especially in areas with high water tables near the High Line Canal. We removed the affected flex section, cleaned the remaining rigid duct with negative-pressure extraction, and applied a Guardsman EPA-registered sanitizer to all interior surfaces. The scope included replacing a 12-foot flex section with new R-6 insulated duct. Written price before any disassembly: $440 for cleaning plus material. The photo record showed the new flex installation and the sanitizer application batch number.
New Construction Debris in Central Park Development
A Central Park homeowner moved into a 2021 build and noticed reduced airflow in the master bedroom. The camera showed drywall chunks and a wood screw in the supply run - common in rapid-build developments where duct installation and drywall finishing happen on compressed schedules. We extracted the debris, verified no punctures in the flex duct with a borescope, and resealed the register boot to the drywall. Written price: $260 for full system cleaning with debris removal. The photo record included the extracted items laid out on the work mat - standard practice so the customer sees what was removed, not just hears about it.
Decades of Neglect in Park Hill Original Ductwork
A Park Hill homeowner in a 1978 ranch had never had the ducts cleaned. The camera showed black accumulation exceeding 3 inches in places, reducing the effective duct diameter by roughly 30 percent. This is the scenario that produces the “vacuum noise” result - a crew runs a hose for an hour, charges a low coupon price, and leaves 80 percent of the material in place. We ran mechanical agitation with a Rotobrush system at calibrated speed for unlined steel, followed by three passes of negative-pressure extraction with a Nikro 5000-series collector. The job took four hours. Written price agreed before work: $380. The customer received 22 before-and-after images and a written scope noting the original duct was in serviceable condition with no replacement needed.
