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 Carlsbad
Air duct cleaning in Carlsbad typically runs $350 – $650 for a full residential system and $800 – $2,400 for commercial jobs, with most homes completed in a single visit. We’re Hollis Air Duct Cleaning, and our crews serve Carlsbad from our San Diego dispatch office. We know the difference between inland dust buildup and what actually clogs ducts here: persistent moisture from the marine layer, salt air corrosion near the lagoons, and microbial growth in aging flex runs that never fully dry out. If your vents push a musty smell every time the handler kicks on, that’s not a filter problem. Call us at (361) 326-5060 for a free estimate and video inspection.
Why Hollis Air Duct Cleaning Is Carlsbad’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our Air Duct Cleaning in Carlsbad crews operate under The Garrison Standard: arrive inside the quoted window, price in writing before any work starts, and leave the site clean. Our technicians are background-checked and uniformed, and our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
Carlsbad homeowners aren’t looking for the lowest teaser coupon. They’re looking for a crew that shows up, does what they said they’d do, and stands behind it. Our 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. The price we write down before we start is the price you pay. It does not move at the door.
We know the local housing stock. West of I-5, Terramar and Olde Carlsbad have older beach bungalows and mid-century homes with original flexible ductwork that sags and collects condensation. Inland, La Costa and Aviara have larger tracts of 1980s-2000s stucco homes with aging HVAC systems that need attention before blower motors strain under improper filter loads. That local knowledge changes how we approach the job.
Residential Air Duct Cleaning in Carlsbad
Residential Air Duct Cleaning in Carlsbad addresses a problem most inland duct cleaners don’t see: moisture-driven microbial growth inside flexible duct runs that stay damp from the marine layer year-round. A typical full-system residential cleaning in Carlsbad runs $350 – $650 depending on system size, accessibility, and whether the air handler and blower motor require attention. We use Rotobrush rotary brush systems and Nikro negative-air machines with HEPA filtration to source-remove buildup, not just push it around.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull air back to the handler. In Carlsbad’s coastal climate, both are prone to condensation on metal collars and microbial growth on flex liners. We clean both sides of the system because treating only the visible registers leaves the main reservoir untouched. Our Air Duct Cleaning team inspects every takeoff and trunk line with a camera before we quote.
Full System Cleaning with Video Inspection
A legitimate clean includes the air handler, blower motor, evaporator coils if accessible, and all trunk and branch lines. We record before-and-after video so you see what was in your ducts and what came out. In Carlsbad, this matters more than in dry climates: the growth you smell is often on the inner liner of flex runs you cannot see from the register.
Commercial Air Duct Cleaning in Carlsbad
Commercial Air Duct Cleaning in Carlsbad serves retail spaces, medical offices, restaurants, and multi-tenant buildings where indoor air quality affects occupancy and liability. Typical commercial jobs in Carlsbad range from $800 for small retail systems to $2,400 for larger multi-zone buildings with rooftop units. We work around business hours, schedule after-hours or weekend service when needed, and provide written documentation for property managers and facilities teams.
Code-Compliant Documentation
Commercial properties in Carlsbad need records of maintenance for insurance and lease compliance. We provide written scope, before-and-after photos, and video on request. Our technicians arrive uniformed and badged, and we coordinate with building engineers so nothing disrupts tenant operations.
High-Volume and Multi-Zone Systems
Larger buildings with multiple rooftop units or VAV boxes require coordinated negative-air setup and sequential zone cleaning. We size our Nikro equipment to the system, not the other way around. No shortcuts on filter changes or blower access. The Garrison Code requires we treat commercial jobs with the same discipline as residential: written price, written guarantee, site left clean.
Trusted Brands We Service in Carlsbad
We clean and service systems with equipment from Rotobrush, Nikro, and Abatement Technologies, and we install filtration upgrades from Honeywell, Aprilaire, and Guardsman when a Carlsbad home’s older blower motor can handle the load. We stock common filter sizes and replacement parts locally so Carlsbad customers aren’t waiting on shipping. If your system needs a MERV upgrade, we check static pressure first. Too high a rating on an aging coastal system pulls more damp air through compromised joints and makes the moisture problem worse.
Common Air Duct Cleaning Problems We See in Carlsbad Homes
- Fogging without source removal. Some outfits spray a “sanitiser” into ducts and call it clean. In Carlsbad’s humidity, the growth stays on the flex liner and returns within weeks because the marine layer never lets the run dry out. Source removal first. Fogging only after, if at all.
- Register-only cleaning. Cleaning what you can see from the floor while skipping the air handler and blower motor. In damp coastal systems, that’s where the main biological reservoir lives. We inspect and clean the full path.
- Over-sized MERV filters on aging blowers. A Carlsbad homeowner upgrades to a high-MERV filter, increases static pressure, and the compromised duct joints in a 1970s Terramar home pull more salty, damp air from the crawl space. We match filtration to blower capacity.
- Ignored corrosion on metal collars. Homes near Agua Hedionda Lagoon and Batiquitos Lagoon show surface rust on takeoff collars years before inland homes. We flag it during inspection so you know whether it’s cosmetic or structural.
Pricing for Air Duct Cleaning in Carlsbad, CA
A typical residential full-system cleaning in Carlsbad runs $350 – $650. Smaller condos or apartments with limited duct runs may fall at the lower end. Larger homes in Aviara or La Costa with multiple zones and longer flex runs trend toward the upper end. Commercial systems start around $800 and scale with square footage, number of rooftop units, and access complexity.
What moves the price: system size, accessibility of the air handler, whether the blower motor and evaporator coils need attention, and the condition of flexible ductwork. We do not quote per-vent pricing. We quote one flat price per system, agreed in writing before work starts. No add-ons at the door. Call (361) 326-5060 for a free estimate. We’ll run a video camera through your ducts and show you exactly what we’re looking at.

FAQs About Air Duct Cleaning in Carlsbad
The musty smell comes from microbial growth on the inner liner of flexible duct runs that stay damp from Carlsbad’s marine layer. New filters catch particulate, not biological growth inside the duct. We inspect with a camera, source-remove the growth with rotary brush agitation and negative-air HEPA extraction, and verify with after-video. Call (361) 326-5060 if you’re smelling it now – the growth doesn’t improve on its own.
Source removal fixes the problem. Fogging without it does not. In Carlsbad’s persistent humidity, spores left on the flex liner regrow quickly. We pulled a sagging flex run out of a 1960s beach bungalow near the Agua Hedionda Lagoon in Terramar where the homeowner kept smelling a musty odor every time the air handler kicked on. Camera inspection showed microbial growth on the inner liner and surface rust on the takeoff collars, so we set up negative pressure with a Rotobrush and HEPA filtration, then agitation tools to source-remove the growth before any sanitiser was ever discussed. The musty smell was gone because the growth was gone – not because we fogged the duct. Call (361) 326-5060 for an inspection and we’ll show you what’s actually in there.
Yes, salt air and persistent moisture near Batiquitos Lagoon accelerate surface corrosion on metal duct components compared to inland Carlsbad neighborhoods. Surface rust on collars is common and often cosmetic. We inspect for structural degradation during our video review and flag anything that needs attention beyond cleaning. Call (361) 326-5060 and we’ll assess whether it’s a cleaning issue or a repair need.
Homes in Terramar and Olde Carlsbad with original flexible ductwork and no modern vapor barrier typically need inspection every 2 – 3 years, and full cleaning when video shows growth or significant debris. Inland Carlsbad homes in La Costa or Aviara with newer duct systems and better moisture control may stretch to 4 – 5 years. The marine layer and older housing stock west of I-5 make the difference. Call (361) 326-5060 for a free video inspection and we’ll tell you where your system stands.
A legitimate clean includes camera inspection before and after, source removal of debris and biological growth from all supply and return ducts, cleaning of the air handler and blower motor, and verification that the system operates properly after service. In Carlsbad, it should also include assessment of flex run condition and metal collar corrosion, because our coastal climate creates problems dust-only markets don’t see. We provide written scope and price before starting, and we guarantee the work for 365 days. Call (361) 326-5060 for an exact quote – estimates are free.
