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.

Seminole’s position between the Gulf of Mexico and Tampa Bay creates a unique problem for ductwork. The salt aerosol that blows inland settles into return ducts, and when it meets Florida’s relentless humidity, it feeds mold and mildew inside the porous fiberglass duct board that dominates local housing stock. We’ve been handling this exact combination since 2004, and we know the difference between a surface fogging that masks the problem and a source-removal clean that actually fixes it.

Ductwork Cleaning in Seminole
Ductwork Cleaning in Seminole requires more than running a brush through metal trunk lines. Most local homes were built between the 1960s and 1980s with fiberglass duct board or flex duct – porous materials that trap salt, humidity, and microbial growth in ways metal ductwork does not. A proper clean here means source removal under negative pressure, HEPA filtration, and often antimicrobial treatment or duct board rehabilitation.
For a typical single-story ranch in Seminole, full ductwork cleaning runs $350 – $550. Larger homes or systems with extensive fiberglass duct board degradation may reach $650. We price by the system, not by the vent, and we write the number down before any work starts.
What Source Removal Actually Means
We use Rotobrush rotary brush systems and Nikro negative-air machines to dislodge debris while drawing it out under suction. This isn’t a shop-vac job. The negative-air method creates a vacuum throughout the duct run so loosened contaminants exit through our collection unit rather than settling in your living room. For Seminole’s older duct board, we follow with inspection cameras to verify the pores are actually clear, not just surface-wiped.
When Duct Board Needs More Than Cleaning
Fiberglass duct board degrades after decades of humidity cycling. If our camera inspection finds the board crumbling or delaminating, cleaning alone won’t hold. We can seal compromised sections with mastic and apply antimicrobial coatings rated for HVAC use – a step that adds $150 – $300 to the job but stops the musty odor from returning in three months. We show you the camera footage and explain exactly what we’re proposing before you decide.
Air Duct Inspection in Seminole
Air Duct Inspection in Seminole should happen before any cleaning quote is finalized, and it’s especially critical after hurricane season or any extended power outage. Our video inspection runs a high-resolution camera through your supply and return lines, documenting salt buildup, mold growth, moisture intrusion points, and duct board condition. The inspection itself costs $150 – $250, and we apply that fee toward your cleaning if you proceed.
We recommend an inspection for any Seminole home built before 1990, any home that smells musty from registers, and any home that experienced flooding or prolonged humidity exposure during a storm outage. The camera doesn’t lie, and it protects you from paying for a cleaning that won’t solve the real problem.
What We Document
Our technicians record footage of fiberglass duct board degradation, flex duct separations at plenum connections, and microbial staining patterns. In Seminole’s climate, we often find the worst damage on the return side near the air handler, where salt-laden air first enters the system. You see what we see, and we explain what each finding means for airflow, energy bills, and air quality.
Post-Storm Assessments
After hurricane season power outages, humid air sits stagnant in ductwork. If your system was off for days and you smell mildew when it restarts, that’s moisture intrusion, not normal dust. Our inspection identifies whether the problem is surface contamination or deeper duct board saturation, so you don’t pay for a standard clean when rehabilitation is actually needed.
Trusted Brands We Service in Seminole
Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines for source removal, plus filtration and treatment products from Honeywell, Aprilaire, and Abatement Technologies. We don’t use hardware-store gear. For Seminole homeowners, this means we can source replacement components and antimicrobial treatments without waiting on national shipping – our Miami coordination office stocks parts for same-week completion on most jobs. When we recommend a Honeywell media filter or Aprilaire dehumidistat integration after your cleaning, it’s because that equipment is proven in Florida’s coastal conditions, not because it’s the easiest upsell.
Common Air Duct Cleaning Problems We See in Seminole Homes
- Musty odors returning within months of “fogging” services. A fogging sanitiser mists the duct surface but doesn’t remove the mildew rooted in degraded fiberglass duct board. The odor comes back because the source never left. We see this constantly in Seminole Grove Estates and Lake Seminole Village, where the salt-humidity combination accelerates board degradation.
- Cleaned metal trunks with untouched fiberglass board runs. Some crews clean what they can reach easily and skip the porous board entirely. In Seminole’s 1960s – 1980s ranches, that’s exactly where the Gulf’s salt aerosol and humidity do their worst work. We inspect and treat the board, not just the shiny metal.
- Storm-season moisture intrusion left unaddressed. Power outages let humid air stagnate in ductwork. A clean that doesn’t include camera verification and re-sealing misses the moisture pockets that restart mold growth. We check plenum connections and board seams specifically for post-storm separation.
- Flex duct collapsed or kinked in attic spaces. Florida attic heat degrades flex duct over decades, and Seminole’s older homes often have original runs that are partially collapsed. This restricts airflow and creates static pressure that pulls unfiltered attic air into leaks. We document this during inspection and can replace damaged sections.

FAQs About Air Duct Cleaning in Seminole
Because the previous service likely fogged or surface-treated the ducts without removing mildew embedded in degraded fiberglass duct board. In Seminole’s humid, salt-laden environment, that board holds moisture and microbial growth that a mist can’t reach. We use source removal under negative pressure, then seal and treat the board itself. Call (361) 326-5060 if you’re dealing with recurring odors – we’ll inspect and show you exactly what’s happening.
Seminole’s peninsula location exposes homes to airborne salt aerosol from the Gulf and Tampa Bay, which settles in return ducts and combines with humidity to accelerate mold growth on porous duct board. Inland Pinellas County doesn’t get the same salt loading. This isn’t a failing of your house – it’s geography, and it requires a different cleaning approach than standard metal-duct work. Our crews know the difference and adjust the scope accordingly.
Ask whether they inspect with a camera before quoting, whether they clean and treat fiberglass duct board (not just metal trunks), whether they use negative-air containment with HEPA filtration, and whether the price is written and final before work begins. Ask for proof of background-checked, uniformed technicians. At Hollis, the answer to all of these is yes, and we document it on every job.
Yes. Extended outages let humid air stagnate in ductwork, and storm-driven rain can infiltrate through compromised seals. After any significant outage or if you smell mildew when the system restarts, schedule an inspection. We check for moisture intrusion, board saturation, and plenum separation – problems a standard cleaning won’t fix if they’ve progressed past surface contamination.
If your home was built between the 1960s and 1980s and has original fiberglass duct board, and if you’ve had recurring musty odors or visible microbial staining, you likely need more than brushing. Our camera inspection shows whether the board is delaminating or crumbling. When it is, we recommend sealing with mastic and antimicrobial coating – a step that costs more upfront but prevents the cycle of clean-and-return that cheaper services deliver. Call (361) 326-5060 to schedule an inspection and see what you’re actually dealing with.
