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.

Why Cardinal Air Duct Cleaning Is St. Petersburg’s Preferred Air Duct Cleaning Company
St. Petersburg homeowners call us because we treat old ductwork like it’s old. Most of the bungalows in Historic Old Northeast, Kenwood, and Old Southeast were framed before central air conditioning was standard, and the ducts got retrofitted later, often poorly. Our technicians understand that a 1925 return duct behaves nothing like a 2015 flex-duct install. The equipment, the pressure, the approach all have to change. That local knowledge is why customers in St. Petersburg keep our number saved.
Every tech who arrives at your door is background-checked, uniformed, and you’ll know their name before they ring the bell. That’s the Relay Standard: a live trackable arrival window, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone. No four-hour windows. No guessing who’s walking up your driveway. Omar Haddad leads our St. Petersburg work with the same standard every booking gets, written price first, written guarantee on every repair, and Dryer Vent Cleaning - St. Petersburg handled with the same care.
Scheduling and dispatch are coordinated from our South Florida office, but the crews working in St. Petersburg know the housing stock. We don’t send someone who’s only ever seen suburban tract homes into a 100-year-old bungalow with duct board returns and expect them to figure it out. The technician who shows up in Crescent Lake or Coquina Key understands what they’re opening before the access panel comes off.
Air Duct Repair in St. Petersburg
Air Duct Repair in St. Petersburg usually means patching, re-sealing, or replacing sections of ductwork that have failed, and in this city, the failure is often age-related rather than damage-related. The original duct board in a 1920s home dries out, delaminates, and the foil tape someone applied after a roof repair fifteen years ago finally gives up. We quote the repair honestly: small re-seal jobs typically run $150 – $350, while replacing a short section of return duct runs $400 – $900 depending on how much access we have in a crawlspace or attic. You get the written price before we cut anything.
Re-Sealing and Mastic Work
Most St. Petersburg duct repairs we do start with mastic, not tape. Mastic is a brush-on sealant that actually bonds to duct board and metal, and it stays flexible as the house moves through Florida humidity cycles. Foil tape dries and peels. That’s the repair we see failing most often in older homes near the water.
Collapsed or Crushed Duct Replacement
When a section of duct board has collapsed, usually from one too many roofers walking across it or from years of negative pressure pulling it inward, cleaning won’t fix it. We replace that section, match the diameter to what the system was designed for, and verify airflow with a camera before and after. You’ll see the photos yourself on the digital invoice.
Ductwork Cleaning in St. Petersburg
Ductwork Cleaning in St. Petersburg is not the same job as cleaning a sealed 2005-era system. When we open a 100-year-old duct, we frequently find roof-repair debris, palm frond fragments, and rodent nesting that only show up on camera. The cleaning has to account for that. We use low-pressure source removal, the trade term for pulling debris out at the air handler and return rather than blasting it with high pressure, which keeps aging duct board from collapsing. For a typical St. Petersburg bungalow, full ductwork cleaning runs $350 – $600 as one flat price for the whole system.
Supply and Return Duct Work
Supply ducts push air out. Return ducts pull air back to the handler. In older St. Petersburg homes, the return is where the real filth lives because it’s been pulling unfiltered air from the house for decades. We clean both, but we don’t charge per register. The price is for the system, not for how many vents we can count.
Full System Cleaning with Video Verification
Every full system cleaning includes a video inspection before we start and after we finish. If we find delaminating duct board or loose joints, we show you the footage on the spot and quote the repair separately. Nothing gets cleaned blindly. You see the inside of your ducts, not just the promise of clean.
Trusted Brands We Service in St. Petersburg
We work on whatever your St. Petersburg home already has installed, and we carry parts for the brands most common around here: Honeywell filtration housings, Aprilaire media cabinets, and Guardsman UV systems. If your system uses a Nikro HEPA-compatible vacuum port for ongoing maintenance, our equipment matches it. We stock common filter sizes and sealants locally, so a re-seal job doesn’t wait on a parts order. For St. Petersburg customers with older systems, we also handle non-branded duct board and metal runs from the original construction. You don’t need to replace everything to clean it properly.
Common Air Duct Cleaning Problems We See in St. Petersburg Homes
- Coastal humidity and mold-like growth: St. Petersburg’s salt air and 70%+ average humidity push condensation into uninsulated ductwork, especially in pier-and-beam homes. We see surface growth in returns more often here than in inland Florida cities.
- Roof debris in the ducts: Flat and low-slope roofs are everywhere in St. Petersburg, and when they get repaired, the old shingles and tar paper end up in the attic, which means they end up in the ducts. Camera inspection catches what a brush alone will miss.
- Collapsed duct board from old repairs: Original 1920s duct board gets brittle, and a previous contractor’s aggressive cleaning or a foot in the wrong place will cave it in. We check for this before we put any tool in the system.
- Pest nesting in the runs: Geckos, palmetto bugs, and the occasional rat all find their way into St. Petersburg ductwork. The droppings and debris they leave behind are why cleaning matters, not just for air quality but for the life of the system.

FAQs About Air Duct Cleaning in St. Petersburg
Every 4 to 7 years for most St. Petersburg homes. Closer to 4 if you have pets, live near the water with constant window-open air, or own a home built before 1940 with original duct board. If you just replaced flooring or did a major remodel that kicked up drywall dust, clean sooner. When a system gets past that window, the return debris we pull out on camera is often the first thing that makes a homeowner realize it was overdue. Call (737) 727-2314 and we’ll tell you honestly whether yours actually needs it.
No. We charge one flat price per system, agreed in writing before any work starts. Per-vent pricing rewards the contractor for counting registers, not for actually cleaning the system. In an old St. Petersburg bungalow, the real filth is in the return and the air handler, not the six supply registers in the hallway. Our price covers the entire system regardless of how many vents your home has.
Not with our process. We use low-pressure source removal and camera verification specifically because high-pressure negative pressure on 1920s duct board collapses the material rather than cleaning it. Before we put any tool into an older system, we stabilize what needs stabilizing and document the condition on camera. If we find damage that predates us, you’ll see it before we proceed. The 365-Day Done Right Promise means if something goes wrong within a year, we return and make it right at no charge.
Yes, every time. The camera inspection runs before we start and the video verification runs after we finish, and you receive both as part of your digital invoice. You’ll see the debris we removed, the joints we re-sealed, and the condition of the duct board we touched. That’s the Relay Standard, and it’s not optional on any St. Petersburg job.
We service whatever your home already runs, and we carry parts for Honeywell filtration, Aprilaire media cabinets, and Guardsman UV systems, among others. If your home has non-branded duct board or metal from the original construction, we work on that too. You don’t need any specific brand of system for us to clean and inspect it properly.
