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.

We’ve worked Gulfport’s low-lying blocks long enough to know the difference between a routine cleaning and a flood-damaged system that needs documenting for insurance. Our dispatch and scheduling are coordinated from our Miami office, but crews serve Gulfport locally and understand the specific problems of 1920s pier bungalows in the Marina District, mid-century slabs in Bayview, and the salt-laden debris that hurricane season pushes into ductwork here. The Garrison Standard means we arrive inside the quoted window, price in writing before touching anything, and leave the site clean.
Why Hollis Air Duct Cleaning Is Gulfport’s Preferred Air Duct Cleaning Company
Hollis has been part of the Garrison Partners family since 2004, and our Gulfport reputation is built on post-storm work that other crews won’t touch. Homeowners here know that after a flood, a low teaser quote for duct cleaning can turn into a much bigger problem if the crew doesn’t understand when replacement is the only safe option.
Our response time to Gulfport is typically same-week for standard cleanings, with priority scheduling for flood-damaged systems where mold growth is active. We don’t promise what we can’t deliver.
Roy Castellanos leads our operation, and every Hollis technician is background-checked, uniformed, and trained on The Garrison Code: arrive squared away, explain the work in plain terms, price it before starting, finish by the book. In Gulfport, that code matters especially because so many homes have been renovated after storms by crews who cut corners on ductwork.
Our Air Duct Cleaning team carries professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, the same tools commercial crews use, and we document every job with before-and-after photos, moisture readings, and camera footage when needed for insurance.
Air Duct Repair in Gulfport
Air Duct Repair in Gulfport is often the necessary next step after storm surge or years of humidity have degraded flex duct, metal seams, or pier-cavity returns beyond what cleaning can fix. In this city’s 1920s – 1950s bungalows, we regularly find salt-corroded connectors, collapsed flex behind air handlers, and return runs that have pulled away from unsealed pier cavities. A typical repair in Gulfport runs $400 – $900 for localized fixes, with full return or supply replacement on flood-damaged systems reaching $1,200 – $2,800 depending on accessibility and materials.
Post-Flood Structural Assessment
After any tidal flooding, we pressure-test and camera-inspect before quoting repair work. Saltwater-soaked insulation loses its structural integrity and its vapor barrier; cleaning it leaves mold spores in the cavity. We document moisture readings and insulation condition so you know whether repair or replacement is the right call.
Sealing and Reconnection
Gulfport’s humidity forces constant HVAC cycling, which vibrates duct seams loose over time. We reseal with mastic, reconnect pulled returns, and verify airflow at each register before leaving. Every repair carries our 365-Day Done Right Promise: if it fails within a year, we return and make it right at no charge.
Ductwork Cleaning in Gulfport
Ductwork Cleaning in Gulfport removes accumulated dust, mold spores, pollen, and salt-laden debris from your HVAC system, but the real question in this city is whether cleaning is sufficient or whether storm damage has made replacement necessary. A standard whole-system cleaning in Gulfport runs $350 – $650 for most homes, with larger systems or those requiring HEPA-level remediation after water intrusion at the higher end. We do not quote per-vent pricing; one flat price per system, agreed before work starts.
Rotary Brush and Negative-Air Methods
Our crews use Rotobrush rotary brush systems for mechanical agitation of duct walls, paired with Nikro negative-air machines that maintain suction throughout the cleaning so debris doesn’t escape into your living space. For Gulfport’s older homes with original metal duct or retrofitted flex, we match the method to the material so nothing gets damaged.
HEPA Filtration and Post-Cleaning Verification
After cleaning, we install or verify filtration from Honeywell, Aprilaire, or Guardsman products appropriate to your system. In Gulfport’s humid climate, proper filtration slows the recurrence of mold and biofilm growth. We show you the before-and-after photos of your own ducts, not stock images.
Trusted Brands We Service in Gulfport
We stock parts and filtration products from Honeywell, Aprilaire, and Abatement Technologies for Gulfport customers, which means faster turnaround when your system needs a component replaced during cleaning or repair. These aren’t hardware-store brands; they’re the same products commercial HVAC crews specify, and we explain what each does for the air moving through your home. If your existing system uses a different filtration setup, we’ll match or upgrade it with equipment that fits properly, not a forced retrofit. Our supply chain runs through our Miami coordination office, so Gulfport jobs don’t wait on parts shipping from out of state.
Common Air Duct Cleaning Problems We See in Gulfport Homes
- Storm-soaked flex duct in Marina District bungalows. After Tropical Storm Eta and other surge events, we’ve pulled flex returns from 1920s pier homes that were technically “dry” but still held salt-compromised insulation. The vapor barrier was shot. Cleaning would have left mold spores active. Replacement was the only safe option.
- Collapsed returns in unsealed pier cavities. Gulfport’s older homes often route return air through the space beneath the floor, between piers. These cavities flood, attract pests, and corrode metal or crush flex. A standard cleaning misses the problem entirely if nobody looks with a camera first.
- Rust and biofilm in unconditioned attics. Year-round humidity in Gulfport means attics that hit 140 degrees in summer and hold moisture all winter. Metal duct rusts. Biofilm grows on the interior surfaces. We find this especially in 1960s – 70s ranch homes with original galvanized duct.
- Salt-laden debris after hurricane season. Even homes that didn’t flood can pull salt aerosol and organic debris through outdoor intakes during storms. This material cakes onto duct walls and blower components, reducing airflow and corroding metal over time.

FAQs About Air Duct Cleaning in Gulfport
They need replacement if the flex duct insulation has taken on saltwater and lost its vapor barrier, which we confirm with moisture readings and camera inspection. If the insulation is structurally intact and the duct is only dusty or lightly mold-stained, cleaning with HEPA containment is sufficient. We document both scenarios with photos and moisture logs so you have evidence for your insurer either way. Call (361) 326-5060 and we’ll schedule the inspection.
Because many 1920s – 1950s homes route returns through unsealed pier cavities that flood, collapse, or harbor standing water invisible from the living space. A camera finds what a register inspection cannot: collapsed flex, rusted metal, active mold colonies, or salt corrosion. We run the camera first on every Gulfport bungalow built before 1960. The $150 – $250 inspection fee is waived if you book the cleaning or repair with us.
Insurers want dated moisture readings, camera stills showing the damage, a written explanation of why cleaning was insufficient, and before/after photos of any replacement work. We compile this documentation set on every post-storm job in Gulfport. Our field vignette from the Marina District: after Tropical Storm surge, we pulled a 1951 pier bungalow’s flex return and found saltwater-soaked insulation sagging against the air handler with rust on the blower motor housing. We ran a camera inspection, confirmed the flex had lost its vapor barrier, and replaced that return and the two supply runs rather than trying to clean them; then we HEPA-vacuumed the remaining trunk and reset the registers. Our documentation set – moisture readings, camera stills, and pre/post photos – went straight to the homeowner’s insurer and the claim was approved without a reinspection.
Surface salt on metal duct can be removed with proper mechanical cleaning and HEPA vacuuming. But when salt has penetrated flex duct insulation or corroded metal seams, cleaning doesn’t restore structural integrity. The salt continues to attract moisture and promote rust. We test with a borescope and moisture meter to determine which scenario applies to your system. If replacement is needed, we explain why in writing with photo evidence.
Gulfport’s humid subtropical climate means HVAC systems run almost constantly, and unconditioned attics and crawlspaces stay damp enough for mold growth and biofilm formation. Most Gulfport homes benefit from duct cleaning every three to five years, but homes with unsealed crawlspaces, prior flooding, or allergy-sensitive occupants may need inspection every two years. The humidity also means filters clog faster, so we check filtration during every cleaning and recommend upgrades when appropriate. Call (361) 326-5060 to discuss your home’s specific conditions.
