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 HVAC Cleaning Across St. Petersburg
HVAC cleaning in St. Petersburg, FL typically runs $450-$850 for a full system clean that includes the air handler, evaporator coil, blower motor, and all supply and return duct runs. That’s the honest range we work within, and it’s the range we put in writing before a single panel comes off. Our crews know St. Petersburg’s housing stock well: 1950s concrete block homes in Magnolia Heights, 1960s ranches in Lakewood Estates, and flood-prone bayside properties in Shore Acres all present different challenges we’ve documented over thousands of local jobs. Call (806) 606-6902 and you’ll get a live person, not a voicemail tree.
Why CleanRun Air Duct Cleaning Is St. Petersburg’s Preferred HVAC Cleaning Company
We’re independent, not a franchise, and we’ve held one practice since 2013: every job gets a written price before work starts. No exceptions. That’s Haven Standard Clause 1, and it matters in St. Petersburg because this city’s older homes rarely have a single clean, simple duct system. Our HVAC Cleaning team has opened enough original flex duct runs in 1960s concrete block homes across St. Petersburg to know what hides in 150°F attics. We don’t guess. We photograph. Every duct run gets a camera pass before and after, and the photos go to you as part of the standard job record. Tomas Reyes, our owner, built the company on that documentation because he saw too many homeowners pay for cleaning they could never verify.
When a St. Petersburg customer calls, we answer. Scheduling for St. Petersburg is coordinated from our South Florida dispatch office, but the crews that arrive are background-checked, uniformed, and carry our equipment roster: Rotobrush, Nikro, Abatement Technologies. They’ll tell you their names before they step inside. And every job carries the 365-Day Done Right Promise in writing. If it’s not right, we make it right. That’s Haven Standard Clause 4, and we don’t hide it in a footer.
Our HVAC Cleaning Services in St. Petersburg
Evaporator Coil Cleaning
The evaporator coil in a St. Petersburg home is the coldest, wettest surface in the entire system. With the city’s water-on-three-sides humidity, that coil stays damp for hours after every cooling cycle ends. Mold cultivates there fast. We remove the coil access panel, photograph the buildup, clean the coil with professional-grade coil cleaner, and treat it to slow regrowth. A typical evaporator coil clean in St. Petersburg runs $180-$320.
Air Handler Cleaning
The air handler is the heart of the system, and in St. Pete it’s often in a closet, a garage, or an unconditioned attic where it ingests humid marine air constantly. We pull the blower housing, clean the blower wheel and motor, vacuum the handler cabinet, and sanitize the interior surfaces. If your air handler lives in a Shore Acres garage that took bay water during a storm event, we’ll document the residue and treat it before it recirculates through your entire duct system. Air handler cleaning in St. Petersburg typically costs $200-$400.
Blower Cleaning
A blower wheel caked with dust and mold spores moves less air and forces your AC to run longer. In a city where AC runs nearly year-round, that inefficiency adds up on your FPL bill every month. We remove the blower assembly, clean each blade, and photograph the before and after so you can see the difference. Blower cleaning alone in St. Petersburg generally runs $150-$250, but we usually recommend it as part of a full system clean.
Condenser Cleaning
The condenser sits outside, where St. Pete’s salt-laden coastal air works on the aluminum fins day and night. Salt corrosion reduces heat exchange efficiency and shortens equipment life. We clean the condenser coil, inspect the fins for salt pitting, flush debris, and check refrigerant line insulation. If your condenser faces the Gulf side or Boca Ciega Bay, expect more aggressive salt buildup. Condenser cleaning in St. Petersburg runs $120-$220.

BeforeAfterTrusted Brands We Service in St. Petersburg
Our technicians maintain and clean systems from every major manufacturer you’ll find in St. Pete homes: Trane, Carrier, Lennox, Rheem, Goodman, and older units we see regularly in 1960s concrete block houses. We service residential equipment, not commercial. For the cleaning itself, we use Rotobrush negative-pressure extraction systems and Nikro HEPA-filtered vacuums, which means we’re not pushing debris around with a shop vac. We carry these tools on every truck that rolls into a St. Petersburg neighborhood, so we don’t need to make a second trip for parts or equipment.
Common HVAC Cleaning Problems We See in St. Petersburg Homes
- Salt-corrosion residue on metal duct interiors. Marine air from Tampa Bay and the Gulf pushes salt molecules through attic vents and into duct runs, where they bond with dust and form a corrosive film. Cleaned ducts can re-contaminate within months if this residue isn’t addressed.
- Mold colonization in slab-adjacent duct runs. In low-lying neighborhoods like Shore Acres and Riviera Bay, bay water intrusion leaves organic sediment inside under-floor ducts. That sediment feeds mold colonies for years after the home looks dry and repaired.
- Crushed or disconnected flex duct in 150°F attics. Pre-1980 concrete block homes in St. Petersburg often retain original flex duct that has collapsed or separated at the seams. Cleaning is only half the fix; the real repair is sealing those disconnected runs.
- Registers cleaned but air handler ignored. Some companies vacuum visible vents and call it a day. We find mold spores, salt residue, and bay sediment still circulating through the blower and evaporator coil, re-contaminating every duct within weeks. That’s why our scope includes the air handler and coil treatment, not just the vent covers.

FAQs - HVAC Cleaning in St. Petersburg
St. Petersburg’s water-on-three-sides geography means ambient humidity stays elevated even when your AC is running, and nightly condensation cycles inside ducts create conditions that inland Hillsborough County homes simply don’t experience at the same intensity. Mold and biofilm accumulate faster here, and salt from bay and Gulf air adds a corrosive element that inland homes never face. Most St. Pete homes need full system cleaning every 2-3 years versus 3-5 years inland. Call (806) 606-6902 and we’ll tell you what your system actually needs after we look at it.
Yes, and this is one of the most common things we document in St. Petersburg. When bay water recedes from a flood event, the organic sediment it leaves inside slab-adjacent and under-floor duct runs doesn’t leave with it. That sediment sits in the dark, stays damp from condensation, and feeds mold colonies for years. The home looks dry. The ducts are not. A camera inspection confirms it, and that’s exactly why we photograph every run before we clean. If your home flooded, we recommend an inspection even if you finished repairs years ago.
Crushed sections, disconnected seams, degraded liner material, and sometimes nests. In St. Petersburg’s 1950s-1970s housing stock, the flex duct installed during original construction was never designed for today’s near-year-round cooling schedules, and sitting in a 150°F attic for six decades breaks down the liner. That degraded material sheds into the airstream. More critically, disconnected runs pull hot, humid attic air directly into the system, reintroducing contamination weeks after a cleaning. We document the condition, clean what can be cleaned, and then quote the sealing or replacement work separately, in writing.
Salt molecules from Tampa Bay and Gulf marine air enter attic spaces through soffit and ridge vents, then settle on metal duct interiors. Over time, they bond with dust and moisture to form a corrosive film that accelerates rust. This means cleaned ducts in St. Pete can develop surface rust and re-contaminate faster than identical systems 20 miles east in Tampa. We inspect for salt corrosion during every cleaning and note it in our photo record, because it changes the recommended cleaning interval and sometimes the repair scope.
We clean everything that touches moving air, including the air handler cabinet, the blower wheel and motor, the evaporator coil, and the full length of every supply and return duct run. Cleaning only visible registers is the easiest way to waste money on a service that doesn’t change indoor air quality. If your air handler sits in a garage or closet that took water, we’ll photograph the mold or sediment before we touch it so you know what we found. That documentation is included on every job.
What We Found in a Shore Acres Home
At a concrete block home in Shore Acres, our techs found the original 1970s flex duct runs in the attic crushed and disconnected, with bay water residue from past tidal flooding feeding mold inside the slab-adjacent supply ducts. After a camera inspection mapped the damage, we performed source removal with HEPA filtration on all supply and return ducts, then sealed the crushed runs and replaced the degraded liner before treating the air handler and evaporator coil. The homeowner received before-and-after photos of every single run. That’s the standard. That’s what documentation looks like.
