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.

AfterFast, Reliable Air Duct Cleaning Across Coronado
Air duct cleaning in Coronado typically runs $350 – $650 for a standard residential system, with most jobs completed in a single visit. Our Coronado crews dispatch from the San Diego office and carry the rotary brush systems, negative-air machines, and camera inspection gear needed for everything from modern beachfront builds to the 1920s Spanish Revival cottages in the historic district. Call (361) 326-5060 for a written estimate before any work starts.
We’ve worked on enough Coronado homes to know the local variables: salt fog corroding galvanized ductwork from the inside, gravity-furnace retrofits with ducts too shallow for standard brushes, and multi-system houses where a single flat-rate quote guarantees one system gets skipped. Our Air Duct Cleaning team prices per system, documents the work with before-and-after video, and stands behind it with the 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is Coronado’s Preferred Air Duct Cleaning Company
Coronado homeowners aren’t looking for the lowest coupon in the mail. They’re looking for a crew that shows up in the window, prices the job in writing before touching anything, and doesn’t disappear when something fails. That’s The Garrison Standard, and it’s how we’ve operated since 2004.
Our technicians are background-checked, uniformed, and accountable. You know who’s walking into your home before they arrive. Phones are answered by a live person 24 hours a day, 7 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 return and make it right at no charge, including a free second visit. No negotiation, no runaround. In a trade where many competitors operate out of vans with magnetic signs, we put our guarantee on paper.
We know Coronado’s housing stock. The 1920s cottages near Orange Avenue with their original gravity furnaces. The post-war bungalows in the Coronado Cays with flex duct that’s turned brittle. The newer luxury homes on Ocean Boulevard where salt-laden marine air works on metal registers year-round. This isn’t mainland San Diego ductwork, and it doesn’t get mainland San Diego treatment.
Commercial Air Duct Cleaning in Coronado
Commercial Air Duct Cleaning in Coronado covers office buildings, retail spaces, restaurants, and hospitality properties where occupancy codes and insurance requirements demand documented HVAC hygiene. Our crews use Nikro negative-air machines and Rotobrush rotary systems sized for larger commercial ductwork, with HEPA filtration to contain debris during the cleaning process. A typical commercial job in Coronado runs $800 – $2,500 depending on system count, square footage, and access conditions. We price per system, put it in writing, and provide video documentation for your facilities manager or inspector.
Restaurant and Hospitality Systems
Grease-laden air from kitchens mixes with coastal humidity and coats duct interiors faster than inland properties. We pull registers, camera-inspect the runs, and use source-removal methods that meet NFPA 96 standards where kitchen exhaust ties into the building’s air handling.
Office and Retail Maintenance Programs
Commercial leases in Coronado often require annual duct inspection and cleaning as a condition of occupancy. We schedule after-hours or weekend work to avoid disrupting business, and we provide the written documentation property managers need for lease compliance and insurance renewals.
Air Duct Cleaning Services in Coronado
Air Duct Cleaning Services in Coronado include full-system source removal for residential properties, with supply duct cleaning, return duct cleaning, and main trunk line cleaning performed as a complete job rather than an a-la-carte menu. We also offer duct sealing with mastic and video inspection to verify the work. A typical residential full-system cleaning in Coronado runs $350 – $650 for a single system; homes with two or three systems common in the Coronado Cays or the Village range $700 – $1,400 total. Every price is written down before we start, and it does not move at the door.
Video Inspection and Documentation
You cannot see inside your walls. We can. Our techs run a camera through the ductwork before and after cleaning, and you get to see the footage. In Coronado’s historic district, this matters especially: we’ve found corroded galvanized steel, previous contractors’ debris, and disconnected flex duct that the homeowner had no way to detect.
Duct Sealing After Cleaning
Cleaning removes the debris. Sealing keeps it from returning through leaks. We apply mastic sealant to joints and connections, particularly critical in Coronado’s older homes where salt corrosion has degraded metal-to-metal connections and created intake paths for attic dust and marine moisture.

Trusted Brands We Service in Coronado
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for controlled debris extraction, and filtration products from Honeywell and Aprilaire. We stock replacement filters and media locally for Coronado customers, so if your system needs a Honeywell F100 or Aprilaire 2200 upgrade after cleaning, we can install it during the same visit rather than ordering parts and rescheduling. The same goes for Abatement Technologies HEPA filtration for homes with allergy-sensitive occupants. No waiting, no return trips, no extra dispatch fee.
Common Air Duct Cleaning Problems We See in Coronado Homes
- Salt-fog corrosion in beachfront ductwork. Homes on Ocean Boulevard and along the Strand draw marine air through intake vents year-round. The salt deposits on metal duct interiors, accelerates rust, and creates a sticky residue that traps dust and mold spores standard brushing alone won’t remove.
- Shallow gravity-furnace ducts that reject standard equipment. In the historic district near the Hotel del Coronado, 1920s retrofits leave ducts so short and shallow that rotary brushes can’t navigate the turns. Crews who don’t hand-vacuum from the crawlspace leave the worst debris behind.
- Undersized flex duct turned brittle in attics. Coronado’s low-clearance attics, especially in 1940s and 1950s bungalows, cook flex duct in summer and trap moisture in winter. The material cracks during cleaning if the technician doesn’t adjust agitation pressure for its condition.
- Multi-system homes quoted as single-system jobs. A house in the Cays with three separate air handlers and long runs through multiple attic zones cannot be cleaned correctly in the time allocated for one system. Per-house pricing guarantees corner-cutting.

FAQs About Air Duct Cleaning in Coronado
Yes, we clean multiple systems in one visit and price each separately so none get shortchanged. A typical three-system home in the Coronado Cays or the Village takes four to six hours and runs $700 – $1,400 total depending on duct condition and access. Call (361) 326-5060 for an exact quote – estimates are free.
Salt-laden onshore breezes and marine fog deposit chloride on metal duct interiors, accelerating galvanic corrosion even when the outside of the duct looks intact. Ocean Boulevard homes are particularly affected because the original galvanized steel ductwork was never designed for decades of salt-air exposure. We camera-inspect for interior corrosion and adjust our cleaning method to avoid flaking rust into your air handler.
Yes. We work within Coronado’s historic preservation guidelines by accessing ducts through existing registers and crawlspace openings rather than modifying walls, ceilings, or architectural features. For 1920s gravity-furnace retrofits near the Hotel del Coronado, we often hand-vacuum from the crawlspace when rotary brushes won’t fit the shallow original ducts. We document our access plan and method before starting so there’s no question about preservation compliance.
You should receive before-and-after video of the duct interior, a written invoice itemizing each system cleaned, and the 365-Day Done Right Promise in writing. We provide all three on every Coronado job. If a contractor won’t show you the inside of your ducts on camera, you have no proof the work was performed. Demand the footage, and call (361) 326-5060 if you want a second opinion on a previous company’s work.
Yes, dryer vent cleaning is $125 – $225 and we can bundle it with duct cleaning in the same appointment. Coronado’s marine humidity causes lint to clump and stick in vent lines more than in drier inland climates, increasing fire risk and drying time. We run a rotary brush through the full vent length and check exterior termination points for corrosion or blockage from salt buildup.
