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.
Fast, Reliable Air Duct Cleaning Across Dunedin
Air duct cleaning in Dunedin typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a few days of your call. We’re the Air Duct Cleaning team that knows what hides in Dunedin’s older homes: original 1920s – 1940s ductwork retrofitted into crawlspaces and attics, not the modern flex duct you’ll find in slab-built subdivisions. Our crews dispatch from the Miami office and serve Dunedin directly, carrying Rotobrush rotary systems and Nikro negative-air machines up the stairs of pier-and-beam bungalows near the marina and through the tight attic chases off Edgewater Drive.

That’s The Garrison Standard, and it’s how every Hollis location operates, including the crews serving Dunedin. Phones are answered by a live person 24 hours a day, 7 days a week, so you’re not waiting until Monday to schedule.
We know the local housing stock. Homes near Honeymoon Island and Caladesi deal with salt air corrosion on metal duct components. Historic downtown properties sit on pilings with equipment access only by stairs or ladder. These aren’t obstacles; they’re details we account for before we arrive. Roy Castellanos and our team have handled enough Dunedin jobs to know that a “routine” clean here often reveals disconnected runs, crushed ducts over pier foundations, and disintegrating fiberglass insulation from the 1940s that newer Pinellas County homes simply don’t have.
Commercial Air Duct Cleaning in Dunedin
Commercial Air Duct Cleaning in Dunedin covers restaurants along Main Street, medical offices near Mease Countryside Hospital, and retail spaces in the downtown corridor where HVAC systems run hard year-round in the humid subtropical climate. A typical commercial job in Dunedin runs $800 – $2,500 depending on system size, access difficulty, and whether we find corrosion or disconnected runs that need sealing. We use Nikro negative-air machines and Rotobrush rotary systems to agitate and extract debris without shutting down your business longer than necessary.
Restaurant and Kitchen Exhaust Systems
Grease-laden vapors from Dunedin’s waterfront dining spots coat duct interiors faster than standard office systems. We clean the full run from hood to rooftop fan, document the work with before-and-after photos, and provide written certification for your insurance and fire inspector.
Medical and Professional Offices
Clinics near Highland Avenue need particulate control that hardware-store vacuums can’t deliver. Our crews use HEPA-filtered negative-air containment and Abatement Technologies filtration to protect patient areas during the clean.
Air Duct Cleaning Services in Dunedin
Air Duct Cleaning Services in Dunedin start with a full-system inspection, not a blind vacuum job. A typical residential clean runs $350 – $650 for a complete supply and return system, with video inspection included so you see what we see. In Dunedin’s 1920s – 1950s bungalows, we regularly find original rigid metal ducts wrapped in collapsed fiberglass batting, crushed runs over pier foundations, and salt-air corrosion at joints near the coast. The price is written down before any work starts, and it does not move at the door.
Video Inspection and System Assessment
We feed a camera through your supply and return lines before touching anything. In a 1946 bungalow near Edgewater Drive, our tech found original 6-inch rigid metal runs with fiberglass batting collapsed into the ducts. Camera inspection showed exactly where the blockage started and where a crushed run had disconnected at a boot over the pier foundation. Without that look first, we’d have cleaned half a system and missed the real problem.

Supply and Return Duct Cleaning
Supply ducts push conditioned air to your rooms; returns pull it back. In Dunedin’s older homes, both runs often sit in uninsulated attics or crawlspaces where humidity and pests take their toll. We clean both sides of the loop, seal accessible leaks with mastic, and re-support sagging runs so the system doesn’t pull attic air or crawlspace debris after we leave.

Trusted Brands We Service in Dunedin
We carry professional-grade equipment and filtration products from Rotobrush, Nikro, Abatement Technologies, Aprilaire, and Guardsman. These aren’t hardware-store tools. A Rotobrush rotary system scrubs duct walls while a Nikro negative-air machine pulls loosened debris out of your home entirely, not just deeper into the system. For filtration upgrades, we stock Aprilaire and Guardsman media that fits the return grilles common in Dunedin’s 1970s – 80s ranch homes and newer waterfront condos. Parts are on the truck, so if we find a corroded fitting or damaged boot during your clean, we can often replace it same visit rather than ordering and rescheduling. That’s how we keep Dunedin jobs moving, whether we’re working off Main Street, near the marina, or up in the Curlew Road corridor.
Common Air Duct Cleaning Problems We See in Dunedin Homes
- Disintegrating fiberglass insulation in 1920s – 1950s attic ducts. Original rigid metal runs were wrapped in fiberglass batting that collapses into the duct after 70+ years of humidity cycles. We find it sucked into supply registers and loaded onto the air handler filter, and without sealing afterward, the system keeps pulling attic air and insulation particles.
- Disconnected or crushed runs over pier-and-beam foundations. Dunedin’s historic bungalows have crawlspaces with limited clearance, and original duct boots get crushed by settling or pest activity. A “clean” that doesn’t inspect these hidden runs leaves half the system pulling crawlspace air into the living space.
- Salt-air corrosion near Honeymoon Island and Caladesi. Metal duct components within a few miles of the coast corrode faster than inland Pinellas County homes. Joints leak, screws fail, and mastic cracks, so humidity and unfiltered air enter the system long before anyone schedules a NADCA-standard clean.
- Snowbird-season dormancy in downtown and marina rentals. Ducts sit idle for weeks when winter residents head north, letting mildew, dust, and pest debris settle. Then the system runs full-blast March through November, blowing accumulated contaminants through the house.

A typical full residential system cleaning in Dunedin runs $350 – $650. Commercial systems start around $800 and range up to $2,500 for larger or multi-unit buildings.

FAQs About Air Duct Cleaning in Dunedin
Because Dunedin’s 1920s – 1940s bungalows were built with raised pier foundations and uninsulated attics, original duct runs were retrofitted into crawlspaces and chases rather than installed as modern flex duct in a slab. A clean frequently reveals crushed runs, disconnected boots, and disintegrating fiberglass insulation that must be reconnected, re-supported, or sealed to stop the system from pulling attic or crawlspace air. Call (361) 326-5060 for an exact quote, estimates are free.
Yes. The original rigid metal ducts wrapped in fiberglass batting are rarely seen in homes built after 1970, and the pier-and-beam construction creates access and support issues that slab-built subdivisions simply don’t have. We regularly find collapsed insulation and disconnected runs in Dunedin’s historic district that would be impossible in a modern ranch on a concrete pad. Call (361) 326-5060 for an exact quote, estimates are free.
Snowbird rentals in the historic downtown and marina district sit empty for weeks during mild winters, allowing dust, mildew, and pest debris to accumulate undisturbed. When residents return and the system runs constantly through the humid months, that accumulated contamination circulates through the house. Year-round homes don’t see this stop-start cycle. Call (361) 326-5060 for an exact quote, estimates are free.
Salt air accelerates corrosion on metal duct components, particularly joints and fasteners, and on damp piers that corrosion combines with humidity so leaks develop long before anyone notices reduced airflow. Homes within a few miles of the coast need more frequent inspection of metal ductwork than inland Pinellas County properties. Call (361) 326-5060 for an exact quote, estimates are free.
A full-system clean of both supply and return sides, agitation and extraction under negative pressure, protection of furnishings and flooring, and written documentation of what was done. In Dunedin, we add video inspection before and after, because older ductwork often hides damage that vacuuming alone won’t fix. The price is agreed in writing before work starts. Call (361) 326-5060 for an exact quote, estimates are free.
