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 Company in Bethel, CT
Air duct cleaning in Bethel, CT typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price locked in before work begins. We’re Hollis Air Duct Cleaning, and our Bethel crews handle the specific challenges that come with this town’s mid-century housing stock and humid river-valley climate. If your home was built between 1950 and 1980 and the ducts have never been opened, you’re likely circulating decades of accumulated dust, mold spores, and allergens. Call us at (361) 326-5060 for a free estimate.
Why Bethel Homes Are Different
Bethel’s housing stock is predominantly single-family homes built between 1950 and 1980, ranches and capes with forced-air systems that have been running continuously for half a century or more. The original ductwork in these homes is often uninsulated, leaky, or made from materials that trap dust and microbial growth. In neighborhoods near the Still River, we regularly find ductwork from mid-century renovations that was never properly sealed, allowing river-valley humidity and outdoor allergens to infiltrate the system year-round.
The humid continental climate here means heavy HVAC reliance in every season. Hot, humid summers promote mold growth inside ductwork, while winter heating dries out and circulates settled dust through the same channels. Bethel’s proximity to the Still River amplifies this, basement and crawl-space ducts in particular pull in moisture that cooler metal surfaces condense into a film where mold colonizes. We’ve opened systems in Bethel where the first register off the main trunk showed black spotting that had been spreading spores through the house every time the blower cycled on.
Our Main Bethel Services
Most Bethel homeowners who call us need one of these three services. Each has its own page with full details on what the job covers, how we price it, and what to expect from our crew.
Air Duct Cleaning in Bethel
We clean the full supply and return network using a Rotobrush rotary brush system paired with Nikro negative-air machines that pull dislodged debris out of your home entirely. In Bethel’s older ranches, we often find the original fiberglass duct board has begun to degrade, releasing fibers into the airflow. Our crew inspects for this damage and documents it with before-and-after photos you can see. Air Duct Cleaning in Bethel covers our full process and pricing.
Dryer Vent Cleaning in Bethel
Lint accumulation in dryer vents is a leading cause of house fires, and Bethel’s older homes often have vent runs that are too long, too many elbows, or terminate in awkward locations that trap moisture. We clear the full line from dryer to termination with rotary tools and airflow meters to verify performance. Our Bethel crews also check for improper materials like plastic flex pipe that should be replaced with solid metal. Dryer Vent Cleaning in Bethel has the details.
Duct Sealing in Bethel
Many Bethel homes lose 20 – 30% of conditioned air through leaks in the duct network before it ever reaches the rooms. We apply duct sealing mastic and mechanical fasteners to joints and seams, then pressure-test the system to verify the seal. In river-adjacent neighborhoods where humidity infiltration is chronic, this work often delivers the most immediate comfort improvement of any service we offer. Duct Sealing in Bethel explains our process and pricing.
