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.
Air Duct Cleaning Company in Half Moon Bay, CA
Air duct cleaning in Half Moon Bay costs differently and works differently than it does over the hill, because the ducts here are fighting fog, not just dust. Most Coastside homes were built between the 1970s and 1990s with flex duct that sits damp for months at a stretch, and the result is microbial growth more often than dust buildup. Morton’s Air Duct Cleaning brings Rotobrush and Nikro equipment, written pricing before work starts, and a crew that protects your floors and works around your family. Call (323) 918-4345 to talk through what your Half Moon Bay home actually needs.
Why Half Moon Bay Homes Are Different
Half Moon Bay sits directly on the Pacific, and the marine layer that rolls in most evenings keeps outdoor humidity between 80 and 95 percent for large parts of the year. Homes here almost never run central air conditioning, which means ductwork can stay idle and damp through spring and summer. That standing moisture inside metal and flex duct is exactly what allows mildew and mold to take hold – a problem our technicians see far more often on the Coastside than dust loading. Then there is the salt. Ocean air corrodes older sheet-metal seams and registers faster than anything inland, leaving rust flakes inside systems that get pulled through the house whenever the heat does kick on.
The housing stock adds its own layer. The tract and planned-community homes built across Half Moon Bay’s suburban expansion in the 1970s, 80s, and 90s often still have their original flex-duct runs, which were never designed for sustained coastal humidity. The older agricultural cottages and bungalows from the early 1900s are a different challenge: many have had ductwork added piecemeal over the years, with mismatched sizes and joints that collect debris. And for homes on the inland-facing edge of town near the brussels sprout, pumpkin, and flower fields along Highway 92, tilling and harvest seasons pull fine agricultural particulates straight into return-air vents. The job here is part cleaning, part moisture management, and part knowing which house you are standing in.
Our Main Half Moon Bay Services
Most Half Moon Bay homeowners call us for one of two jobs, and each has its own dedicated Half Moon Bay page with full pricing and local detail. Here is what each one involves on the Coastside.
Air Duct Cleaning in Half Moon Bay
Air duct cleaning in Half Moon Bay means addressing what the fog leaves behind: microbial buildup inside ducts that stay damp, salt corrosion on older metal, and organic debris pulled in from the coastal farmland. Our technicians run professional agitation and HEPA-filtered collection equipment from Rotobrush and Nikro through the full system, including supply and return runs. We protect floors with shoe covers and drop cloths, give you a written price before anything starts, and photograph the clean-up before we leave. See the full local breakdown here: Air Duct Cleaning in Half Moon Bay.

Dryer Vent Cleaning in Half Moon Bay
Marine humidity makes dryer lint cling inside vent runs, and longer Coastside vent paths through crawlspaces or up through roofs compound the problem. A clogged dryer vent forces your dryer to run longer and hotter, and it is the leading cause of dryer fires in single-family homes. In Half Moon Bay we see extra lint moisture, salt film on vent interiors, and occasional nesting material from roof or wall caps. We clear the full run from dryer to exterior cap with professional equipment, then show you the before-and-after. Full details are here: Dryer Vent Cleaning in Half Moon Bay.

FAQs About Air Duct Cleaning Company in Half Moon Bay
We schedule Half Moon Bay jobs on a route-based calendar, which means we group Coastside appointments to avoid sending crews over Highway 92 twice in one day. Most Half Moon Bay customers get a visit within one to two weeks, and we confirm the exact window the day before.
Duct cleaning is interior work and almost never requires HOA approval in Half Moon Bay’s planned communities. If your ductwork runs through shared walls or you are planning flex-duct replacement that touches building structure, a quick note to your HOA is wise, but cleaning itself does not need a sign-off.
The coastal fog does not stop our work. Duct cleaning happens inside your home, and our equipment does not depend on dry weather. The moisture issue matters for why we clean and whether we recommend antimicrobial treatment, but rain, fog, or salt air will not reschedule your appointment. Call (323) 918-4345 for a free estimate.

What Half Moon Bay Customers Say
"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
