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.

Air Duct Cleaning Services in St. Petersburg
Air Duct Cleaning Services in St. Petersburg cover the full removal of dust, debris, mold, and flood-borne contaminants from your supply and return ductwork using source-removal methods that meet NADCA standards. A typical residential cleaning in St. Petersburg runs $350 – $650 for a standard single-system home, while larger homes or those with multiple zones run $550 – $850. Commercial systems start around $800 and scale with square footage and access difficulty.
Our Air Duct Cleaning process starts with a video inspection so you see what we see. We then seal the system and apply negative pressure using Nikro equipment, agitate debris with Rotobrush rotary tools, and capture everything in HEPA filtration before it enters your living space. In St. Petersburg’s climate, we also evaluate for mold growth and moisture intrusion that might require sanitizing or duct sealing with mastic.
Residential Duct Cleaning
St. Petersburg’s housing stock runs from 1920s bungalows with original galvanized ducts to 1960s ranch homes with flex duct and newer condos with tight chases. Each type demands a different approach. Older galvanized systems need careful agitation to avoid dislodging rust scale into your air handler. Flex duct requires lower-pressure cleaning to prevent collapse or tearing.
Video Inspection and Documentation
We run a camera through every accessible section before and after cleaning. In flood-impacted homes, this documentation becomes evidence for your insurer. Photos, moisture readings, and written findings are compiled into a report we hand you before we leave.

HVAC Duct Cleaning in St. Petersburg
HVAC Duct Cleaning in St. Petersburg addresses the entire forced-air system: supply trunks, return plenums, branch lines, registers, grilles, and the air handler cabinet itself. A full system cleaning in St. Petersburg typically costs $450 – $850 for residential properties, with pricing driven by system size, accessibility, and whether post-storm contamination requires additional steps. Commercial HVAC duct cleaning starts at $1,000.
The difference between a basic duct cleaning and full HVAC duct cleaning is the air handler. In St. Petersburg’s humidity, mold colonizes blower wheels, evaporator coils, and drain pans. Cleaning ducts without addressing the air handler is incomplete. Our crews use Abatement Technologies HEPA containment and Nikro negative-air machines to capture dislodged debris rather than redistribute it.
Post-Storm Flood Recovery
After hurricane-season flooding, we evaluate whether ducts can be cleaned or must be replaced. Silt and mud in flex duct almost always require replacement. Galvanized trunks may be salvageable if rust-through hasn’t occurred. We document everything for your insurer.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; returns pull it back. Returns run dirtier because they draw in household dust. In St. Petersburg homes near the water, returns also pull in salt-laden air that accelerates corrosion in metal ductwork. We clean both sides of the system, not just the easy reaches.
Trusted Brands We Service in St. Petersburg
We carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and stock filtration products from Honeywell and Aprilaire for St. Petersburg customers who want upgraded protection after cleaning. These aren’t hardware-store tools. A Nikro negative-air machine pulls 2,000+ CFM through your system while HEPA filtration captures particles down to 0.3 microns. Honeywell and Aprilaire media filters install directly at your air handler and trap what bypasses standard disposable filters. We keep common sizes in stock, so replacement after a cleaning doesn’t mean waiting on a warehouse shipment.
Common Air Duct Cleaning Problems We See in St. Petersburg Homes
- Flood-contaminated flex duct in Shore Acres and low-lying neighborhoods. Storm surge pushes silt and mud through return grilles and supply registers. Flex duct acts like a sponge, trapping moisture and debris against the insulation layer. Cleaning doesn’t restore it. Replacement is the only safe option, and it has to be documented correctly or your insurer denies the claim.
- Mold blooms in original galvanized ducts of 1920s Kenwood bungalows. Seventy percent relative humidity, year-round, creates ideal conditions for mold inside rust-pitted galvanized steel. Crews that skip camera inspection miss hidden colonies. We find them, photograph them, and remove them with source-removal methods, not chemical fogs that mask the problem.
- Salt corrosion in coastal condos near Tampa Bay. Salt-laden air drawn through return ducts accelerates metal fatigue. We inspect for rust-through and separation at joints, then seal salvageable sections with mastic or recommend replacement where integrity is compromised.
- Post-storm “cleaning” jobs that redistribute mold instead of removing it. Crews working without negative pressure or HEPA filtration dislodge mold spores and silt, then your blower pushes them into every room. We contain before we agitate. Period.

FAQs About Air Duct Cleaning in St. Petersburg
Flex duct that has taken on floodwater almost always requires replacement; galvanized steel trunks may be salvageable if rust-through hasn’t occurred and the interior can be source-cleaned to NADCA standards. After a storm pushed water into a low-slung ranch home in Shore Acres, our crew ran a camera inspection through the supply and return ducts and found mud coating the flex runs and the air handler cabinet, so we pulled the saturated sections, documented the intrusion with photos and moisture readings, and replaced rather than cleaned. We set up negative pressure with HEPA filtration during the work, cleaned the salvageable galvanized trunks with agitation tools, and handed the homeowner a written report the insurer accepted on the first submission. Call (361) 326-5060 if you’re dealing with post-storm duct damage. We’ll inspect and document before you file.
St. Petersburg’s combination of 70%+ average relative humidity, summer temperatures in the 90s, and frequent hurricane-driven moisture intrusion creates more aggressive mold conditions than inland Florida cities. Orlando and Jacksonville get hot, but they don’t get the sustained salt-air exposure and storm-surge flooding that St. Petersburg’s low-lying neighborhoods experience. Mold colonies that might take two years to establish in drier climates can establish in six months here. We see it most often in original galvanized ducts of 1920s bungalows, where rust pitting provides anchor points for spores, and in flex duct that has ever taken on water. Regular video inspection catches it before it spreads. Call (361) 326-5060 to schedule.
We provide before-and-after video, dated photos of moisture readings, written findings of contamination type and extent, and a clear statement of why replacement meets coverage criteria versus cleaning. Insurers deny claims when documentation is vague or when a crew simply states “ducts are dirty.” We show them mud in the flex, rust scale in the galvanized, moisture readings above 16% in surrounding framing, and the NADCA standard that requires replacement when porous materials are contaminated with Category 3 water. Our Shore Acres field experience means we know what adjusters need to see. Call (361) 326-5060 and we’ll walk you through the documentation before you file.
Yes. Galvanized steel ducts from the 1920s – 1950s develop rust scale that can dislodge during aggressive cleaning, damaging your air handler or redistributing metal fragments through your home. We use lower-RPM rotary brushes and reduced negative pressure, with camera guidance to identify thin spots and rust-through. In Kenwood and Old Northeast, we regularly see spring failures due to decades of salt-air corrosion at joints. We document these findings and recommend replacement where integrity is compromised, rather than cleaning ducts that will fail in the next storm season. The approach takes longer. It costs what it costs. But it doesn’t create a bigger problem than it solves. Call (361) 326-5060 for an assessment.
NADCA compliance means source removal (physical debris extraction, not chemical masking), containment of the work area, protection of the HVAC system during cleaning, and documentation of before-and-after conditions. On a St. Petersburg job, this matters most post-storm, when Category 3 water contamination requires specific protocols. NADCA-compliant crews don’t just vacuum visible debris; they seal the system, establish negative pressure, agitate and extract from every accessible section, and verify results with video. Non-compliant crews often skip containment and use antimicrobial fogs as a substitute for physical removal, which insurers reject and which leaves mold colonies intact. We do it by the book. Call (361) 326-5060 for a NADCA-standard cleaning quote.
