We’ve been cleaning ductwork in this fog belt since 2004, and we know the local conditions that wreck ducts here: salt-laden air that corrodes metal, persistent moisture that breeds biological growth, and heavy dust loading from unpaved roads and open agricultural land. Our Air Duct Cleaning team arrives with negative-air machines from Nikro, rotary brush systems from Rotobrush, and antimicrobial treatments formulated for coastal environments.

Why Hollis Air Duct Cleaning Is Half Moon Bay’s Preferred Air Duct Cleaning Company

Half Moon Bay homeowners don’t need another coupon in the mailbox promising a $49 whole-house special that balloons to $800 at the door. They need a crew that shows up uniformed, prices the job in writing before touching anything, and stands behind the work for a full year.

That’s The Garrison Standard. Every Hollis technician is background-checked and arrives inside the quoted window. The price we write down is the price you pay. No per-vent add-ons, no surprise charges once the van is in your driveway. Our 365-Day Done Right Promise means if the work fails within a year, we return and make it right at no charge, including a free second visit.

We know the local housing stock. Many Half Moon Bay homes were built in the 1950s to 1970s with original galvanized or flex duct systems that have decades of coastal wear. Newer developments like Ocean Colony have tighter envelopes that trap moisture. Both need different approaches, and our crews are trained to assess which methods apply.

Vent Cleaning in Half Moon Bay

Vent Cleaning in Half Moon Bay addresses the supply and return vents where your conditioned air enters and exits living spaces. In this coastal environment, vents collect more than household dust: they trap salt particles, sand, pollen from surrounding open land, and the biological film that forms when fog belt humidity condenses on cool metal surfaces. A typical vent cleaning for a Half Moon Bay home runs $150 – $300 as part of a larger system service, or $200 – $400 as a standalone appointment for homes with extensive buildup.

Supply Vent Restoration

Supply vents push heated or cooled air into your rooms. In Half Moon Bay’s older ranch homes, we often find these vents partially blocked by decades of compacted dust mixed with salt residue. Our rotary brush system loosens this material while negative-air containment captures it at the source, rather than blowing it back into your home.

Return Vent Deep Cleaning

Return vents pull air back toward your air handler, making them the primary collection point for airborne debris. Homes near unpaved rural roads see return vents clog faster than suburban properties. We remove the vent covers, clean the boot and trunk line connections, and verify unrestricted airflow before reassembly.

Air Duct Repair in Half Moon Bay

Air Duct Repair in Half Moon Bay fixes the physical damage that coastal conditions inflict on ductwork: corroded galvanized steel, separated flex duct seams, crushed runs from decades of maintenance neglect, and moisture-damaged insulation. A typical repair in Half Moon Bay runs $250 – $600 for localized fixes such as section replacement or resealing, while extensive system rehabilitation can reach $1,200 – $2,500. We always inspect with a camera first, show you the footage, and write the repair price before any cutting or sealing begins.

Corrosion and Leak Sealing

Salt air attacks galvanized ductwork from the inside out, particularly in homes that draw outdoor air through attic vents or crawl space openings. We identify corroded sections, replace what cannot be salvaged, and seal remaining joints with mastic rated for coastal humidity. This restores system pressure and stops conditioned air from leaking into unconditioned spaces.

Flex Duct Replacement

Original flex duct from the 1960s and 1970s becomes brittle and sags over time. In Half Moon Bay’s damp climate, the inner liner can delaminate and harbor mold. We replace failed runs with new insulated flex duct, properly supported to prevent future sagging and condensation pooling.

Trusted Brands We Service in Half Moon Bay

Our equipment roster includes Nikro negative-air machines for containment during cleaning, Honeywell and Aprilaire filtration products for system upgrades, and Abatement Technologies HEPA filtration for jobs where environmental sensitivity matters. We stock common parts and filtration media for Half Moon Bay customers, which means faster turnaround when your system needs more than cleaning: a new media filter, an upgraded return air grille, or a sealed plenum repair. Our technicians carry the tools to complete most repairs in a single visit, rather than ordering parts and leaving your system open.

Common Air Duct Cleaning Problems We See in Half Moon Bay Homes

• “Fog funk” odor from biological growth. The persistent marine layer keeps duct surfaces damp enough for mold and mildew to colonize, producing a musty smell that locals recognize immediately. Standard cleaning without antimicrobial treatment leaves the root problem intact.
• Accelerated corrosion in coastal homes. Salt-laden air drawn through attic vents and crawl spaces corrodes galvanized ductwork years faster than inland equivalents. We inspect with cameras to catch this before leaks become severe.
• Heavy dust and pollen loading from rural roads. Properties on or near unpaved roads in the El Granada and Miramar areas see filter clogging and duct coating that suburban homes don’t match. Source removal requires proper agitation and negative pressure, not just a shop vacuum.
• Condensation in newer tight construction. Ocean Colony and similar developments trap moisture inside the building envelope. Without adequate ventilation and periodic duct cleaning, this moisture condenses on cool duct surfaces and feeds biological growth.
