We’ve been in business since 2004 as part of the Garrison Partners family. Every job gets a written price before we start, a 365-Day Done Right Promise in writing, and a crew that shows up uniformed, background-checked, and on time. That’s The Garrison Standard. It means no price that moves at the door, no disappearing after the invoice is paid, and no guesswork about whether the work was actually done.

Why Hollis Air Duct Cleaning Is St. Augustine’s Preferred Air Duct Cleaning Company

St. Augustine homeowners call us because they’ve already dealt with the alternative: a coupon price that doubled once the van pulled in, a crew that tracked mud through a 1920s hallway, or a musty smell that returned two weeks after “cleaning.” We don’t compete on the lowest teaser number. We compete on the number you can hold in your hand, written down, that doesn’t change.

Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday for a scheduling question.

The 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a slogan. It’s a document you sign.

We know St. Augustine’s specific challenges: the salt air that corrodes duct fittings, the king tides that push water into crawlspaces on St. George Street and Aviles Street, the shared ventilation systems in downtown condos where one unit’s mold becomes everyone’s problem. Our Air Duct Cleaning crews adapt their approach for this city, not apply a template from somewhere drier.

Vent Cleaning in St. Augustine

Vent Cleaning in St. Augustine removes the buildup of dust, pollen, pet dander, and mold spores that accumulate in supply and return vents due to the area’s year-round humidity and salt-laden air. A typical residential vent cleaning for a St. Augustine home runs $150 – $300 for standard systems, with larger or more complex setups reaching $400. We use Rotobrush rotary brush systems to agitate debris loose from vent walls, then extract it with negative-air machines so nothing resettles in your living space.

Supply vs. Return Vent Focus

Supply vents push conditioned air into your rooms; return vents pull air back to the handler. In St. Augustine, return vents near crawlspace or floor level often show the heaviest mold staining because they draw in the damp, musty air that rises from flooded substructures. We clean both sets, but we inspect returns first. That’s where the moisture damage usually announces itself.

Condos and Shared Vent Stacks

Many St. Augustine condos, especially in the historic district and along the bayfront, share vent stacks between units. Cleaning one vent without isolating the system can redistribute debris into a neighbor’s ducts. Our crews seal and isolate each branch before agitation, then verify flow with a smoke pencil. Shared systems demand more setup time. We quote that time honestly, not bury it in a flat rate that forces us to cut corners.

Air Duct Repair in St. Augustine

Air Duct Repair in St. Augustine addresses the corrosion, separation, and moisture damage that this city’s salt air and tidal flooding inflict on metal and flex ductwork. Typical repairs range from $200 – $500 for sealing and patching corroded sections, to $800 – $1,500 for replacing damaged duct runs in hard-to-access historic homes. We write the full scope and price before touching anything.

Corrosion from Salt Air

St. Augustine’s sea breezes carry salt that accelerates rust on galvanized fittings and air handler cabinets. We inspect for corroded seams and failed seals that leak conditioned air into attics or crawlspaces. Where we find it, we replace with corrosion-resistant components and seal with mastic, not tape that degrades in humidity. The goal is a repair that lasts past the next hurricane season.

Flood Damage and Duct Replacement

When king tide or storm surge pushes water into crawlspaces, it often pools in low points of duct runs. Standing water breeds mold and weakens flex duct. Our crew documents the damage with video inspection, removes the contaminated material, and replaces with properly sloped hard pipe where access allows. We don’t patch over wet ducts and call it done. That’s not repair. That’s delay.

Trusted Brands We Service in St. Augustine

We stock parts and filtration products from Honeywell, Aprilaire, and Guardsman for St. Augustine customers, which means faster turnaround on repairs and replacements without waiting on freight from Atlanta or Orlando. Our equipment roster includes Rotobrush rotary brush systems for thorough agitation cleaning and Nikro negative-air machines for controlled debris extraction. When your system needs a new filter housing, a corroded fitting replaced, or an upgraded media filter to handle the pollen load from St. Augustine’s live oaks and salt marsh grasses, we typically have it on the van. If we don’t, our Miami office coordinates same-day or next-day supply. No two-week waits for a part that should be standard.

Common Air Duct Cleaning Problems We See in St. Augustine Homes

• King-tide crawlspace flooding pushes standing water directly into ductwork. In the historic downtown, century-old Spanish Colonial and Victorian homes often have original crawlspaces that flood during king tides, creating a distinct musty odor locals recognize immediately. Standard vacuuming won’t fix this; source removal and antimicrobial treatment are required.
• Salt-laden sea breezes accelerate corrosion on duct components and air handlers. We regularly find rusted fittings that compromise blower motor seals and create air leaks. Inspections in coastal St. Augustine homes often reveal corrosion that inland Florida techs rarely see.
• Historic homes with original plaster walls and custom ductwork make equipment access difficult. Negative pressure setups must be adapted to fragile structures. Our crews use smaller-diameter hoses and manual agitation tools where rotary brushes won’t fit.
• Shared building systems in condos can spread odors between units if source removal is incomplete. We’ve responded to calls from downtown condo associations where one unit’s mold problem became a building-wide complaint because the original cleaner didn’t isolate the branch lines properly.
