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 Oldsmar
Air duct cleaning in Oldsmar typically runs $350 – $650 for a full residential system and $800 – $1,800 for commercial jobs, with most homes completed in a single visit. We’re Hollis Air Duct Cleaning, and our crews work Oldsmar regularly – from the concrete-block ranches west of SR-580 to the newer townhomes around East Lake.

Oldsmar homeowners call us back because the price on the page matches the price at the door. No per-vent add-ons, no “we found something extra” once the van is in your driveway. One flat price per system, agreed before we touch anything.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. And when you call (361) 326-5060, a live person answers – 24 hours a day, seven days a week. No voicemail loops, no callback queues, no waiting until Monday for a human voice.
The local knowledge matters here. Oldsmar sits directly on Tampa Bay’s eastern shore, so ducts in bayside neighborhoods like Bexley and Oldsmar Landing accumulate a salt-crystal-and-black-mold coating that inland Tampa suburbs don’t see. Cleaning here requires a corrosion-inhibiting treatment after the vacuum, not just a standard pass. Crews who don’t know that difference leave your ducts clean for a month, then the problem rebounds.
Vent Cleaning in Oldsmar
Vent Cleaning in Oldsmar means more than wiping down the register covers you can see from the hallway. We HEPA-vacuum every supply and return vent, run a rotary brush through the branch lines, and inspect the boot connections where flex duct meets the wall or ceiling. In Oldsmar’s 1980s and ’90s concrete-block ranches west of SR-580, we regularly find boots that have separated from the drywall, dumping conditioned air into the attic or wall cavity.
Supply Vent Cleaning
Supply vents push cooled or heated air into your rooms. We remove each register, clean the grille and the boot behind it, then run a Rotobrush rotary brush system through the branch duct to dislodge dust and mold buildup. In bayside Oldsmar homes, that buildup often includes salt crystals mixed with black mold – a combination standard brushes alone won’t fully remove.
Return Vent Cleaning
Return vents pull air back to the air handler, so they’re the dirtiest points in most systems. We clean the grille, the filter rack, and the return trunk. Skipping the returns is common in this trade. We don’t. If your return is pulling air through a clogged filter or a cracked trunk, your whole system works harder and your energy bill climbs.
A typical residential vent cleaning in Oldsmar runs $150 – $300 as part of a full system clean, or $250 – $450 as a standalone service for homes with 8 – 15 vents.
Air Duct Repair in Oldsmar
Air Duct Repair in Oldsmar often starts with what looks like a cleaning call. Homeowner notices weak airflow upstairs, or one room never matches the thermostat. We open the air handler and find crushed flex duct, disconnected runs, or gaps where mastic has dried and flaked away. In a 1988 concrete-block ranch off Shore Drive in Oldsmar Landing, our techs pulled the air handler panel and found the original flex duct crushed flat where a past attic re-route had been zip-tied to a joist; camera inspection showed a disconnected run dumping conditioned air into the insulation. We reconnected and sealed the run, HEPA-vacuumed the supply and return ducts under negative pressure, fogged the interior with an antimicrobial to kill the bay-driven mold, then applied a corrosion inhibitor – the homeowner’s second-floor registers finally matched the thermostat setpoint.
Flex Duct Replacement
Original flex duct in Oldsmar’s older homes degrades after 20 – 30 years. The insulation compresses, the inner liner tears, and the wire helix corrodes in the humid attic air. We replace damaged runs with new R-8 flex or rigid duct, sealed with mastic at every joint. Typical flex duct repair or replacement in Oldsmar runs $200 – $500 per run, depending on attic access and length.
Duct Sealing and Reconnection
Disconnected runs and leaky joints waste 20 – 30% of conditioned air in the average Oldsmar attic. We reconnect separated ducts, seal gaps with duct sealing mastic, and pressure-test the repair. The work is priced in writing before we start, and it’s covered by our 365-Day Done Right Promise – if the seal fails or the connection separates, we come back at no charge.
Trusted Brands We Service in Oldsmar
We clean and repair ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Oldsmar customers who want to upgrade while we’re on site. Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines – the same tools commercial crews use, not hardware-store gear. If your air handler needs a new filter rack or you want a media filter upgrade after the cleaning, we can typically install it same visit. Parts are ordered through our Miami coordination office with next-day availability for most items, so you’re not waiting a week for a filter housing or a replacement return grille.
Common Air Duct Cleaning Problems We See in Oldsmar Homes
- Salt-crystal and black mold coating in bayside neighborhoods. Homes in Bexley and Oldsmar Landing get year-round salt-laden air off Tampa Bay. The salt crystals embed in duct dust, and the humidity feeds black mold. A standard vacuum leaves both behind. We follow cleaning with antimicrobial fogging and a corrosion-inhibiting treatment.
- Crushed or disconnected flex duct in 1980s-’90s ranches west of SR-580. Original flex duct in these attics was often poorly supported. Over decades, it sags, gets stepped on by cable installers, or gets zip-tied to joists during re-routes. Camera inspection finds the damage, and we repair or replace the run.
- Sticky salt-spray film after tropical storms. Wind-driven salt spray enters through roof vents and coats duct interiors with a film standard vacuums can’t touch. It requires a degreasing agent and pressure washing, then the full antimicrobial and corrosion-inhibiting sequence.
- Poor sealing in newer East Lake townhomes with rigid duct. Rigid duct is durable, but builders often rush the mastic at joints. Bay-area humidity gets pulled into leaky return trunks, making the house feel clammy even when the thermostat reads 72. We seal the leaks and verify with pressure testing.

FAQs About Air Duct Cleaning in Oldsmar
Oldsmar sits directly on Tampa Bay’s eastern shore, so salt-laden air blows into bayside neighborhoods like Bexley and Oldsmar Landing year-round. Salt crystals embed in duct dust and accelerate corrosion on metal components, while the humidity feeds black mold. The corrosion-inhibiting treatment we apply after cleaning bonds to metal surfaces and slows salt attack. Inland suburbs like Lutz or Wesley Chapel don’t see this combination, so a standard vacuum-and-brush pass is usually sufficient there. Call (361) 326-5060 if you’re in a bayside Oldsmar neighborhood and want to know whether your system needs the treatment.
Camera inspection in these homes typically reveals crushed flex duct where past contractors or cable installers compressed it against joists, disconnected runs where mastic has failed, and mold colonies in the air handler pan. We also find original duct that was never properly sealed at the boot connections, dumping conditioned air into attics or wall cavities. The inspection costs $150 – $250 and includes a full report with photos. Call (361) 326-5060 to schedule.
Wind-driven salt spray enters through roof vents and outdoor air intakes during tropical storms, coating duct interiors with a sticky film that standard vacuums can’t remove. The film traps humidity and feeds mold growth, producing a musty or briny smell that persists even after the storm passes. We remove it with a degreasing agent and pressure washing, then follow with antimicrobial fogging and the corrosion-inhibiting treatment. If your ducts smell different after a storm, that’s the likely cause. Call (361) 326-5060 for an inspection.
Yes. We clean to NADCA ACR standards: source removal with mechanical agitation, negative-air containment, and post-clean verification. For Oldsmar’s bayside homes, we add the corrosion-inhibiting treatment and antimicrobial fogging as site-specific steps beyond the standard, because the salt-and-mold environment here demands it. Every job is documented, and we show you before-and-after photos of your own ducts. Call (361) 326-5060 for details on our process.
Rigid duct is durable, but builders often seal joints with tape instead of mastic, or skip sealing entirely at hidden connections. In Oldsmar’s high-humidity climate, leaky return trunks pull in attic air that’s 80%+ humidity, overwhelming your dehumidification. We pressure-test the system, seal every leak with duct sealing mastic, and verify the fix. The repair typically runs $400 – $900 for a whole townhome system. Call (361) 326-5060 for a free inspection and written price.
