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 Half Moon Bay, CA
Air duct cleaning in Half Moon Bay is a different job than it is ten miles east over Highway 92. The coastal fog that hangs over this town most of the year doesn’t just sit outside. It works its way into the ductwork of homes in Arleta Park, Frenchman’s Creek, and the older cottages near Main Street, and once moisture gets inside a forced-air system, mold and mildew follow. If you’ve noticed a musty smell when the heat kicks on, or dust settling on furniture a day after you wiped it down, call Kestrel Air Duct Cleaning at (469) 972-3151. We’ll give you a written price before any work begins, and the 365-Day Done Right Promise in writing on every job.
Why Half Moon Bay Homes Are Different
Half Moon Bay sits directly on the Pacific under one of the most persistent marine layers in California. Relative humidity stays elevated year-round, and salt-laden fog rolls through on most days, including summer afternoons when inland cities bake in dry heat. That creates a condensation problem inside ductwork. When a forced-air system cycles, the temperature difference between the cool coastal air and the duct interior causes water to bead inside the runs. Technicians who work the Coastside see biological growth in ducts here at rates far above what homeowners report in San Mateo or Redwood City.
The housing stock makes it worse. Many older Half Moon Bay homes were built as seasonal cottages or agricultural housing, with minimal insulation and aging flex-duct that sags, separates, and lets moisture in. Homes within a half-mile of the shoreline have an additional problem: salt crystallization on metal duct collars and fittings. It’s the same corrosive effect that eats car finishes along the coast, and it weakens duct joints and promotes debris buildup at failing seams. Re-sealing work is common on Half Moon Bay jobs that a standard inland cleaning would never need.
Our Main Half Moon Bay Services
Half Moon Bay homeowners call us most often about two things: the air ducts that move heated and cooled air through the house, and the dryer vent that carries hot, lint-filled exhaust outside. Each service has its own page with local pricing and specifics.
Air Duct Cleaning in Half Moon Bay
Air Duct Cleaning in Half Moon Bay means addressing what the marine layer deposits inside your system. We use negative-air extraction, which means a powerful vacuum creates suction at the duct opening while rotary brushes agitate the walls, pulling loosened debris out of the house rather than stirring it into the living space. In Half Moon Bay, we frequently find mold and mildew growth that requires cleaning and then re-sealing joints to stop moisture entry at the source.
Dryer Vent Cleaning in Half Moon Bay
Dryer Vent Cleaning in Half Moon Bay is a safety issue in many Coastside homes. Lint accumulates faster in high-humidity environments because it clings instead of staying loose, and clogged dryer vents are a leading cause of house fires. We run a rotary brush through the full vent run and bypass the lint trap so the airflow path gets cleared end to end. If your dryer takes more than one cycle to dry towels, the vent likely needs attention.

What Half Moon Bay Customers Say
"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
- Marcus Lee"Set up an appointment for the whole house plus the dryer line. They called the morning of to confirm, showed up in the window, and showed me pictures of the gunk they pulled out. Worth it."
- Terrence Boyd"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
