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 Half Moon Bay Homes Are Different
Half Moon Bay sits where the Pacific marine layer meets the Santa Cruz Mountains, and that combination shows up inside your ductwork. Homes here run their heat more months of the year than the Bay Area average, and the salt-heavy fog that rolls through Frenchmans Creek, Ocean Colony, and the downtown grid means duct interiors collect a finer, stickier particulate than you’d see inland. We find coastal homes hold moisture in the return side longer, which bonds dust to the duct walls. That changes the cleaning approach: longer dwell time with the rotary brush, and a HEPA extraction pass that actually pulls the loosened debris out rather than letting it resettle. Older bungalows and 1970s ranchers dominate the housing stock, and many still have their original sheet-metal trunk lines wrapped in degraded insulation, which sheds fibers into the airflow over time.
Our Main Half Moon Bay Services
Half Moon Bay homeowners call us most for two things: dryer vents packed with coastal lint buildup, and full HVAC air duct cleaning on older systems. Here’s what each job looks like locally.
Dryer Vent Cleaning in Half Moon Bay
Dryer vents in Half Moon Bay clog faster than inland because the damp, salt-laden air makes lint clump and stick to the vent walls instead of blowing through. Runs from laundry rooms on the ground floor to exterior vents near decks and crawlspaces are common, and longer runs with multiple elbows are exactly where blockages form. We clean the full run from dryer to termination point, then verify airflow with a meter so you’re not guessing. Dryer Vent Cleaning in Half Moon Bay has full pricing and process details.

Air Duct Cleaning in Half Moon Bay
Full air duct cleaning here means addressing what the fog deposits: a fine, sometimes gritty film that coats supply and return ducts. We run a Rotobrush rotary brush through every accessible trunk and branch line, paired with a Nikro HEPA vacuum in negative-pressure mode, so the loosened material goes straight into containment, not back into your living room. Homes along Higgins Canyon Road and in the hills often have flex-duct runs that require gentler brush speeds. Air Duct Cleaning in Half Moon Bay breaks down the full scope and what to expect.

HVAC Cleaning in Half Moon Bay
HVAC cleaning covers the components that move and condition your air: blower fan, evaporator coil, drain pan, and the cabinet interior. In Half Moon Bay, coil fouling from salt air and constant mild temperatures means systems run longer but less efficiently, and a fouled coil is the single biggest drag on airflow. We pull the access panels, clean the coil with professional-grade solutions, and sanitize the drain line so condensate keeps moving. HVAC Cleaning in Half Moon Bay covers what’s included and typical turnaround.
