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 Seminole
Most homes in Seminole run between $380 and $650 for a full residential duct cleaning, and we can usually schedule within a few business days. We dispatch crews from our South Florida coordination office and serve Seminole neighborhoods directly, including the ranch homes off Seminole Boulevard, the blocks near Lake Seminole, and the built-out subdivisions between Park Boulevard and Bryan Dairy Road. Our Air Duct Cleaning team knows what to expect in this market: original or first-replacement ductwork from the 1960s through the 1980s, decades of salt-humid coastal air, and the collapsed flex runs that turn a standard cleaning into a repair-and-reseal job. Call (469) 972-3151 for a free written estimate.

Air Duct Repair in Seminole
Air Duct Repair in Seminole often starts with a phone call for “cleaning” and ends with our technician in your attic reconnecting a flex run that separated from the plenum in 1987. The housing stock here - concrete block ranch homes built during the 1960s-1980s postwar boom - carries original or early-replacement ductwork that has endured 130-140°F attic temperatures and salt-laden marine air for decades. A typical repair in Seminole runs $280-$520 depending on how many runs need resealing, plenum reconnection, or partial flex replacement. We camera-inspect first, show you what we found, and get written approval before any repair work begins.
Collapsed Flex Runs Behind Joists
Flex duct installed in the 1970s and 1980s can crush or pinch behind attic joists, especially after decades of thermal cycling in Seminole’s extreme attic heat. No amount of vacuum pressure will move air through a flattened tube. We locate the obstruction with a borescope, free the run, and reinstall with proper support strapping so it stays open.
Separated Plenum Connections
The connection between your air handler plenum and the main trunk line is a common failure point in older Seminole systems. Salt-humid air corrodes tape and mastic over time, and the thermal expansion of 10-11 months of annual A/C cycling finishes the job. We reseal with mechanical fasteners and fresh mastic, then pressure-test before closing up.
Ductwork Cleaning in Seminole
Ductwork Cleaning in Seminole means source removal with agitation tools under controlled negative pressure - not a glorified vacuum job. We use Rotobrush rotary brush systems to dislodge debris at the duct wall, Nikro negative-air machines to pull loosened contaminants out of your system, and Abatement Technologies HEPA filtration to keep those particles out of your living space during the work. A typical whole-system cleaning in Seminole runs $380-$650 for residential properties, with commercial systems quoted site-unseen after a brief walkthrough. We clean supply ducts, return ducts, and the main trunk lines; we also inspect and clean the air handler cabinet and blower assembly as part of a full system service.
Negative-Air Extraction With HEPA Containment
Our Nikro units create a controlled vacuum throughout your duct system while the Rotobrush scrubs the interior surfaces. The Abatement Technologies HEPA filter captures particles down to 0.3 microns, so the dust we loosen doesn’t resettle in your bedrooms or living room. This matters in Seminole, where year-round A/C means any disturbed contamination would otherwise recirculate immediately.
Video Inspection Before and After
We run a camera through your ducts before we start and again when we’re done. You see the buildup. You see the clear passage. No guesswork, no trust-me assertions. The footage is yours to keep, and it’s the proof that the work happened inside your actual ducts - not a stock photo from someone else’s job.
Trusted Brands We Service in Seminole
We clean and service ductwork connected to all major HVAC brands, and we stock filtration products from Honeywell, Aprilaire, and Guardsman for Seminole homeowners who want to maintain cleaner air between professional cleanings. Our technicians carry common plenum fittings, flex duct, and mastic on the van, so most repairs don’t require a return trip. If your system needs an indoor air quality upgrade - a media filter cabinet, a UV light, or a whole-home dehumidifier - we can source and install Honeywell and Aprilaire products with fast turnaround from our South Florida supply chain. We don’t upsell equipment you don’t need, but we’ll show you what’s available if your 1970s ranch is struggling with the humidity load that comes with living two miles from the Gulf.
Common Air Duct Cleaning Problems We See in Seminole Homes
- Separated flex duct at the plenum. On a 1979 CBS ranch off Seminole Boulevard near Lake Seminole, our tech pulled the return grille and found the flex run separated at the plenum in the attic - supply ducts sagging, liner shedding, and crushed runs pinched behind a joist that had never moved air properly since the 1980s. We camera-inspected the whole system, resealed and reconnected the plenum and branch runs, then performed source removal with agitation tools under negative pressure with HEPA filtration at the air handler. The homeowner had booked a cleaning; the real fix was the reseal, and only then did the clean actually change what came out of the registers.
- Degraded fiberglass liner shedding into airstream. Original 1970s-80s fiberglass-lined sheet metal ducts in Seminole attics have cooked for decades at 130-140°F. The liner degrades, sheds fibers, and creates a porous surface that traps moisture and microbial growth. You can’t see this from the register. We find it with the camera, and we tell you before we proceed.
- Condensation at supply register boots. When aged duct insulation fails in a Seminole attic, the extreme heat outside the duct meets the cold conditioned air inside. Moisture forms at the register boot, stains the ceiling, and breeds mold. Cleaning the duct won’t fix failed insulation. We flag it, show you, and recommend rewrapping or replacement before the ceiling damage spreads.
- Microbial buildup from year-round moisture cycling. Seminole’s Gulf-proximity humidity and 10-11 months of annual A/C operation create constant moisture cycling inside ducts. Salt-laden marine air accelerates corrosion and provides the environment for mold and mildew to reestablish far faster than in drier inland markets. A single cleaning without addressing seals and insulation just resets the clock.
Pricing for Air Duct Cleaning in Seminole, FL
A typical residential full-system cleaning in Seminole runs $380-$650. Duct repair and reseal work, which we find necessary on roughly half of the older homes we service here, adds $280-$520 depending on how many runs need attention. Commercial systems are priced individually after a walkthrough. What moves you within these ranges: the number of supply and return vents, whether the ductwork is accessible or buried in soffits, the condition of existing flex or liner, and whether we need to bring in HEPA containment for known mold contamination. We give you one flat price per system, agreed in writing, before any work begins. No per-vent pricing. No teaser coupon that balloons at the door. Call (469) 972-3151 for a free estimate - we’ll ask a few questions about your home’s age, square footage, and any symptoms you’ve noticed, then give you a range you can plan around.

FAQs About Air Duct Cleaning in Seminole
Because the flex duct in your 1960s-1980s ranch home has often separated at the plenum or collapsed behind a joist after decades of salt-humid attic conditions, and no vacuum can pull debris through a tube that isn’t connected. We camera-inspect first, show you the failure, and reseal before we clean. Call (469) 972-3151 for a free estimate - we’ll check accessibility and give you a written range that covers both possibilities.
Yes. Seminole sits roughly two to three miles from the Gulf, and the salt-laden marine air that infiltrates attic spaces combines with 10-11 months of annual A/C moisture cycling to accelerate mold, mildew, and corrosion inside ducts. Inland Hillsborough County suburbs with drier air and more seasonal system downtime don’t see the same rate of microbial buildup. Call (469) 972-3151 for a free estimate and we’ll assess your system’s condition.
Degraded liner that has cooked at 130-140°F for decades, shedding fibers and creating a porous, moisture-trapping surface. The liner was never designed for that thermal load over forty-plus years. We find it with our borescope, document it with video, and recommend repair or replacement before cleaning so we don’t dislodge loose material into your living space. Call (469) 972-3151 for a free estimate.
Your attic duct insulation has failed, allowing the extreme Seminole attic heat to meet the cold conditioned air inside the duct. Moisture condenses at the register boot, stains your ceiling, and creates a mold habitat. Cleaning the duct interior won’t fix failed exterior insulation. We flag it during inspection and recommend rewrapping or replacement. Call (469) 972-3151 for a free estimate.
No. The combination of original never-replaced ductwork, salt-humid coastal air, and continuous moisture cycling means microbial growth and corrosion rebuild faster here than in markets with seasonal downtime. We recommend addressing seals and insulation first, then establishing a maintenance interval based on what we find. Call (469) 972-3151 for a free estimate and we’ll build a plan for your specific system.
