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.

AfterFast, Reliable Air Duct Cleaning Across St. Petersburg
Air duct cleaning in St. Petersburg typically runs $350-$650 for a whole-home system, with most jobs completed in a single visit. We serve homes from Historic Kenwood to Shore Acres with crews dispatched from our South Florida coordination office, so St. Petersburg appointments are scheduled with realistic arrival windows and no phantom “same-day” promises that never materialize. Call (323) 918-4345 for a free written estimate.
We’ve worked in enough St. Petersburg bungalows to know the routine: a homeowner notices weak airflow in the back bedrooms, or a musty smell every time the AC kicks on, or a utility bill that keeps climbing despite a new thermostat. Often the problem isn’t the unit itself. It’s ductwork that was retrofitted through a 140°F attic in the 1980s, held together with tape that’s turned to powder, pulling humid salt air through gaps that no filter can catch. Our Air Duct Cleaning team treats every house like the family lives there, because they do.
Why Morton’s Air Duct Cleaning Is St. Petersburg’s Preferred Air Duct Cleaning Company
We’ve been part of the Cedarwell family since 2005, and our reputation in St. Petersburg has been built one appointment at a time, mostly through neighbors telling neighbors. Homeowners in Roser Park and Old Southeast know our vans because we’ve been on their streets for years, not because we bought ad space.
Our reviews from St. Petersburg customers consistently mention the same things: the written price that matched the final invoice, the technician who noticed the sleeping toddler and switched to quieter tools, the photo of clean floors left on the counter before we left. We don’t chase stars. We earn them by showing up in uniform, putting on shoe covers before we cross your threshold, and doing what we said we’d do.
Scheduling to St. Petersburg is coordinated from our Miami office, which means we plan routes carefully rather than overpromising speed. You’ll get a real arrival window, not a four-hour black hole. And our technicians know the local housing stock: which streets flood in a hard rain, which attics are accessible only through closet hatches, which 1920s crawl spaces require a different approach entirely.
Residential Air Duct Cleaning in St. Petersburg
Residential Air Duct Cleaning in St. Petersburg means source removal of accumulated particulate, biological growth, and construction debris from supply and return ductwork, followed by sealing of accessible joints and collars. Most St. Petersburg homeowners need this service when they notice persistent musty odors, uneven cooling between rooms, visible mold near registers, or after any major renovation. A typical whole-home residential cleaning in St. Petersburg runs $350-$550 for a single system, with larger homes or separated systems (common in additions) ranging up to $650. We provide a written price before any equipment enters your home.
What We Find in Older St. Petersburg Homes
Pre-1960 bungalows in Kenwood and Roser Park were built for window units, not central air. The retrofit ductwork we encounter was often routed through unconditioned attics with minimal support, leading to crushed runs, sagging flex, and collars that have separated entirely. Our field inspection identifies these failures before we quote, so you’re not paying for a cosmetic clean while air leaks into your insulation.
Protecting Your Home During the Visit
We lay drop cloths at the entry and along every path to the work area. Shoe covers stay on until we exit. In homes with pets, we use pet-safe products where available and keep hoses and equipment clear of feeding areas. If there’s a nap schedule, we plan our noisiest work accordingly. The Cedarwell Care Promise isn’t a slogan. It’s a checklist.
Commercial Air Duct Cleaning in St. Petersburg
Commercial Air Duct Cleaning in St. Petersburg serves offices, retail spaces, medical clinics, and multi-unit buildings where HVAC load and occupancy patterns differ sharply from residential systems. We clean supply and return ductwork, air handling units, and accessible coils using Nikro and Abatement Technologies equipment sized for larger volume. St. Petersburg commercial clients typically schedule every 2-3 years, or after any construction or water intrusion event. Commercial pricing starts around $800 for small offices and scales with system complexity; we provide itemized written quotes before scheduling.
Minimizing Disruption to Your Business
We work evenings and weekends when needed, and we section off work areas so your staff or customers aren’t navigating around equipment. Our crews are background-checked and uniformed, and we document the condition of shared spaces with photos before we start and after we finish.
Video Inspection for Property Managers
Multi-unit buildings in St. Petersburg’s commercial corridors benefit from our video inspection service, which records duct interior conditions for maintenance records and tenant communications. You’ll see exactly what we see, with no interpretation required.
Trusted Brands We Service in St. Petersburg
Our equipment comes from manufacturers who build for daily professional use, not weekend rental: Rotobrush and Nikro for agitation and extraction, Honeywell and Aprilaire for filtration and media upgrades, Abatement Technologies for negative-pressure containment on larger jobs. We stock common fittings and collar sizes for St. Petersburg’s predominant duct types, which means most repairs don’t wait on a parts run. When we find a component that needs replacement during a clean, we can usually source and install it in the same visit, with the cost included in your written price.
Common Air Duct Cleaning Problems We See in St. Petersburg Homes
- Disconnected or crushed flex runs in superheated attics. Retrofitted ductwork in pre-1960 bungalows often hangs unsupported in St. Petersburg attics that exceed 140°F for months at a time. The flex collapses, separates at collars, or gets buried in insulation, so cooled air never reaches the register.
- Condensation wicking through aging seams. The constant temperature differential between 55°F duct air and a 140°F attic, combined with St. Petersburg’s near-perpetual humidity, creates exterior condensation that finds every tape failure and rusted seam. Mold follows.
- Salt-air rot in waterfront neighborhoods. In Shore Acres, Coquina Key, and Venetian Isles, flex duct jackets near floor registers or in crawl spaces deteriorate from the outside in, composted by salt air and high groundwater moisture while the inner liner still looks fine. We’ve pulled runs where the outer jacket came off in strips.
- Mold colonization in duct liners. With AC running 10-11 months yearly and humidity rarely dropping below 60%, St. Petersburg duct liners that have gotten wet stay wet. No filter change fixes biological growth inside the duct.

FAQs About Air Duct Cleaning in St. Petersburg
St. Petersburg’s peninsula geography exposes HVAC systems to salt-laden humidity from Tampa Bay, the Gulf of Mexico, and Boca Ciega Bay simultaneously, while inland Tampa has more buffered air. The triple exposure accelerates condensation on duct exteriors and corrosion of metal components, creating conditions where mold colonizes months or years sooner than across the bay. If you’re comparing notes with Tampa relatives, expect shorter maintenance intervals here. Call (323) 918-4345 and we’ll assess your specific system.
We find flex duct suspended with inadequate support in unconditioned attics, often routed through access hatches too small for proper installation, with collars that have separated and tape that has degraded to powder. In one Historic Kenwood job, our tech pulled a supply run in a 1948 bungalow where the retrofitted flex duct was suspended in an attic that had been baking past 140°F all summer - the outer jacket had collapsed into the insulation and the run had separated from the trunk, so half the bedrooms were getting almost no air. We ran a camera inspection, did source removal under negative pressure with HEPA filtration, then reconnected and sealed the run at the collar. The homeowners noticed stronger airflow at every register before we packed up. We provide a written price for this scope of work before starting.
Yes. These low-lying waterfront neighborhoods, built on fill land barely above sea level, experience salt air intrusion and high groundwater moisture that cause flex duct jackets to rot from the outside in while the inner liner still holds its shape. Technicians in these zip codes routinely find outer jackets that have essentially composted, a failure mode almost never seen in higher-elevation Florida cities. We inspect for this specifically in waterfront appointments and include any needed jacket replacement in our written quote.
NADCA-compliant cleaning means source removal of contaminants using controlled agitation and negative-pressure extraction, not just blowing compressed air through registers. We seal the system, create negative pressure at the air handler, mechanically agitate duct walls with Rotobrush or Nikro equipment, and capture debris with HEPA filtration. Access points are created and restored properly. We document the work with before and after photos, included with every job.
Most St. Petersburg homes benefit from cleaning every 3-5 years, sooner if you have pets, recent construction, or visible mold. The near-constant AC operation here accumulates particulate and biological growth faster than in climates with a true winter shutdown. Homes in waterfront neighborhoods or with pre-1960 retrofitted ductwork may need inspection every 2-3 years. We don’t sell annual cleans to people who don’t need them. Call (323) 918-4345 for an honest assessment of your interval.
