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
Most St. Petersburg homeowners pay between $380 and $620 for a complete residential duct cleaning, with older homes in neighborhoods like Kenwood and Old Northeast often running higher due to access challenges and the sealing work that follows. We’re Kestrel Air Duct Cleaning, and we serve St. Petersburg from our South Florida dispatch office in Miami, with crews that know the difference between a 1970s CBS flex-duct system and a 1920s bungalow retrofit. If you’re smelling musty air when your handler kicks on, or your energy bills keep climbing while your home never quite cools, your ductwork is likely the culprit. Call us at (469) 972-3151 for a free estimate with a written price before any work begins.
St. Petersburg sits on a peninsula enclosed by Tampa Bay to the north and east and Boca Ciega Bay to the west, producing persistently higher ambient humidity than anywhere else in the Tampa Bay metro - not just seasonally, but year-round. That moisture causes mold colonization inside ductwork to advance far faster than in inland markets like Brandon or Wesley Chapel. On top of that, St. Pete holds the oldest and densest housing stock in Pinellas County, with large concentrations of 1920s-1950s bungalows and CBS homes where central AC was retrofitted into attic and wall cavities never engineered for it. The result: moisture traps that make duct cleaning both more urgent and more technically demanding here than in newer suburban markets.
Why Kestrel Air Duct Cleaning Is St. Petersburg’s Preferred Air Duct Cleaning Company
We’ve been serving Florida homeowners since 2004 under the Kingswell Guarantee, and our St. Petersburg customers get the same four written promises on every job: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if anything fails within the guarantee period. Dale Whitmore, who leads Kestrel Air Duct Cleaning, built this operation on the principle that a homeowner should never have to argue about what was promised versus what was delivered.
Our technicians are background-checked, uniformed, and trained on St. Petersburg’s specific housing stock. They know that a home on 22nd Avenue North in Kenwood may have duct runs threaded through original ceiling cavities with zero access panels, while a 1960s ranch near Tyrone Boulevard likely has aging flex duct baked brittle in attic temperatures that regularly exceed 140°F. That local knowledge means we show up with the right equipment and the right expectations, not a one-size-fits-all approach. Calls are answered by a live person, 24/7 - not a voicemail queue, not an automated system. When you call (469) 972-3151, you get a real conversation and a real appointment window.
Our 365-Day Done Right Promise is documented in writing on every single job. If the work falls short within that year, we return and make it right at no charge. No courtesy extended at our discretion - it’s a standing commitment, and it’s in your hands before we pack up the van.
Commercial Air Duct Cleaning in St. Petersburg
Commercial Air Duct Cleaning in St. Petersburg covers office buildings, retail spaces, restaurants, and multi-unit residential properties where HVAC systems run harder and longer than in single-family homes, often pulling in salt-laden air from Tampa Bay and Boca Ciega Bay that accelerates corrosion and biological growth inside metal trunk lines. A typical commercial duct cleaning in St. Petersburg runs $1,200-$3,800 depending on system size, access configuration, and whether the building dates to the mid-century construction boom or is newer construction near the downtown waterfront. We schedule commercial work to minimize disruption to your operation, and we provide the written price before any equipment is touched.
System Assessment and Access Planning
Commercial buildings in St. Petersburg’s historic Core District or along Central Avenue often have mechanical spaces retrofitted multiple times since original construction. Our techs map the full system, identify access points, and flag any fire-damper or balancing-damper locations before cleaning begins. This prevents damage to controls and ensures we don’t miss branch lines hidden above drop ceilings.
Negative-Pressure Source Removal with HEPA Containment
We use Nikro negative-pressure units to create suction throughout the duct network while Rotobrush rotary brush systems dislodge debris at the duct wall. Abatement Technologies HEPA filtration keeps loosened particles out of occupied spaces during cleaning. This matters especially in St. Petersburg restaurants and medical offices where air quality directly affects health inspections and patient outcomes.
Air Duct Cleaning Services in St. Petersburg
Air Duct Cleaning Services in St. Petersburg from Kestrel cover the full residential system: supply ducts, return ducts, trunk lines, and the air handler cabinet, with camera inspection included on every job involving pre-1980 construction. A typical whole-system residential cleaning in St. Petersburg runs $380-$620, with homes in Kenwood, Old Northeast, or Historic Uptown often requiring additional access work or section replacement that can push the total toward $780-$1,100. We never quote per-vent pricing, and we never revise the price at your door.
Residential Full System Cleaning
Our residential process starts with a video inspection using a flexible borescope camera. In St. Pete’s older neighborhoods, this step is non-negotiable - we’ve found crushed flex runs, disconnected joints, and rodent-damaged sections that no amount of surface cleaning would fix. We show you the footage, explain what we’re seeing, and give you the full written price before any cleaning or repair work begins.
Post-Cleaning Sealing and Verification
Cleaning without sealing is often half a job in St. Petersburg. Our techs pressure-test the system after source removal and seal disconnected joints with mastic and mechanical fasteners where accessible. In homes with original retrofit ductwork, we may recommend section replacement or access panel installation to bring the system closer to NADCA cleanability standards. We verify airflow improvement with before-and-after measurements, and we leave you with photos of your own ducts.

Trusted Brands We Service in St. Petersburg
Kestrel technicians clean ductwork connected to every major HVAC brand, and we stock Honeywell and Aprilaire filtration products for St. Petersburg homeowners who want to maintain clean air between service visits. Honeywell electronic air cleaners and Aprilaire media filters install directly at the return plenum, capturing particles before they enter the duct system - a significant advantage in a market where year-round humidity keeps biological growth active. For commercial clients, we also source Guardsman filtration products suited to high-occupancy spaces. Our Miami-based dispatch coordinates fast parts turnaround for St. Petersburg jobs, so we’re not waiting on shipments while your system sits offline.
Common Air Duct Cleaning Problems We See in St. Petersburg Homes
- Crushed or disconnected flex duct in unconditioned attics. In 1950s-1970s CBS homes throughout St. Petersburg, original flex duct has been running in attic heat exceeding 140°F for decades. The lining degrades, the wire helix collapses, and sections separate at couplings - creating leaks that pull hot attic air into the system and dump conditioned air into spaces where it does no good.
- Mold colonization accelerated by peninsula humidity. St. Petersburg’s three-sided exposure to open water keeps relative humidity higher than inland Tampa Bay markets. Duct interiors stay moist even when the AC cycles off, allowing mold to establish within supply lines and return plenums. Surface cleaning without addressing the moisture source - often leaking or uninsulated runs - means the problem returns within months.
- Inaccessible retrofit ductwork in historic bungalows. Homes in Kenwood and Old Northeast frequently have duct runs threaded through original ceiling cavities during 1960s-1980s AC retrofits, with no access panels and returns built into wall stud bays. Cleaning equipment cannot reach these sections without first locating them by camera, and the real fix often involves cutting access openings or re-routing runs through properly conditioned spaces.
- Disturbed debris without proper containment. Some contractors agitate decades of accumulation in St. Pete’s older homes without adequate negative pressure or HEPA filtration. The result: mold spores, dust-mite debris, and fiberglass particles pushed back into living spaces instead of removed from the home. Our Nikro and Abatement Technologies equipment prevents this.
Pricing for Air Duct Cleaning in St. Petersburg, FL
Here’s what honest pricing looks like for St. Petersburg’s market. Most whole-home residential cleanings run $380-$620. Homes with straightforward access, post-1990 construction, and intact flex duct tend toward the lower end. Older homes in Kenwood, Old Northeast, or Historic Uptown - where camera inspection reveals crushed runs, missing access panels, or mold-damaged sections requiring replacement - typically run $620-$1,100 depending on how much sealing and re-routing is needed. Commercial systems start around $1,200 for small offices and scale to $3,800+ for multi-unit or restaurant installations with extensive trunk-line networks.
What affects your specific price: system size and vent count, age and accessibility of ductwork, presence of mold or rodent damage requiring remediation-level work, and whether sealing or section replacement follows the cleaning. We give one flat price per system, agreed in writing before any work starts. No per-vent add-ons. No door-step revisions. Call (469) 972-3151 for a free estimate - we’ll ask about your home’s age, neighborhood, and any symptoms you’ve noticed, then give you a range you can plan around.

FAQs About Air Duct Cleaning in St. Petersburg
St. Petersburg’s peninsula geography produces higher year-round humidity than inland markets like Brandon, which keeps duct interiors moist and accelerates mold colonization. Your friend’s system in Brandon may stay dry enough between cycles to slow biological growth; yours doesn’t get that break. Call (469) 972-3151 and we’ll assess whether your duct configuration is trapping moisture even more than typical for St. Pete.
Expect that the ductwork was added during a 1960s-1980s retrofit, likely threaded through original ceiling cavities with no access panels and returns built into wall stud bays. We’ll start with a camera inspection to map what exists, locate any crushed or disconnected sections, and give you a written price that includes both cleaning and the access work or sealing needed to make the system maintainable. Most Old Northeast bungalows run $620-$1,100 for this level of work.
Cleaning alone is rarely enough in St. Petersburg if the root cause is leaking, disconnected, or uninsulated ductwork that keeps the interior moist. We seal accessible joints and replace failed sections during the cleaning process, and we show you before-and-after photos so you can see what was fixed. Our 365-Day Done Right Promise covers the work - if mold returns because we missed a leak, we come back at no charge.
We routinely find crushed flex runs baked brittle by 140°F attic temperatures, disconnected couplings dumping conditioned air into unconditioned spaces, rodent-damaged sections, and mold coating the duct wall - none of which is visible from the vent grille. In Kenwood and Old Northeast bungalows, we also find returns jury-rigged into wall stud bays with no proper duct connection, meaning the system has been pulling air from inside walls for decades. Camera inspection is mandatory before cleaning in any pre-1980 St. Petersburg home.
