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.
Fast, Reliable Air Duct Cleaning Across Sanibel
Air duct cleaning in Sanibel typically runs $380-$650 for a full residential system, and our crews schedule most jobs within a week of your call. We’re the local Air Duct Cleaning team that understands Sanibel’s stilt homes, salt-air climate, and the ductwork headaches that followed Hurricane Ian.
Our dispatch office coordinates scheduling from Miami, with crews serving Sanibel directly. We know the island’s elevated construction, the under-floor chases where flex duct weathers salt and humidity, and the post-rebuild problems that mainland techs miss. When you call (469) 972-3151, a live person answers, day or night. We’ll give you a written price before any work starts, and we back every job with our 365-Day Done Right Promise.
Why Kestrel Air Duct Cleaning Is Sanibel’s Preferred Air Duct Cleaning Company
We’ve built our reputation on Sanibel by showing up in the window we promised and documenting every guarantee in writing. Our technicians are background-checked, uniformed, and trained specifically on the island’s elevated stilt construction, not generic slab-home systems.
Sanibel homeowners call us back because we find what others miss. The disconnected flex joints in under-floor chases. The salt-crusted biofilm that shop vacs can’t touch. The lizard entry points where 2023 rebuild crews skipped sealing. We use Rotobrush rotary brush systems, Nikro negative-pressure extraction, and Abatement Technologies HEPA filtration, real equipment that pulls debris from duct walls instead of pushing it deeper.
Our 365-Day Done Right Promise means if the work falls short within a year, we return and make it right at no charge. No courtesy discretion, no phone tag. It’s in writing on every invoice.
Calls are answered by a live person 24/7. Not a queue. Not a callback tomorrow. A real conversation about your Sanibel home, your schedule, and what we’ll find when we get there.
Air Duct Inspection in Sanibel
Air Duct Inspection in Sanibel is where we start every job, because this island’s ductwork tells a story no mainland home can match. We run a video camera through your supply and return lines, paying special attention to the under-floor chase where salt air, humidity, and post-Ian rebuild shortcuts create failure patterns unique to Sanibel’s stilt construction. A typical inspection runs $180-$280, and we’ll show you the footage before quoting any cleaning or sealing work.
What We Look For in Elevated Homes
Our camera hunts for disconnected collars, sagging flex runs pooling condensation against pilings, and gaps where lizards or insects enter the system. These aren’t theoretical problems on Sanibel. On a call to a stilt home off West Gulf Drive, our tech dropped a camera inspection into the under-floor chase and found the 2023 rebuild crew had left three flex duct joints disconnected and a sagging run pooling condensation against the piling.
Static Pressure and Airflow Testing
We test static pressure at the blower motor to spot ductwork that was sized for speed during the rebuild, not for the actual cfm of your new air handler. High static pressure means your system works harder, your energy bills climb, and debris never fully clears from the lint pathway.
Residential Air Duct Cleaning in Sanibel
Residential Air Duct Cleaning in Sanibel means dealing with ductwork that lives in open-air under-floor chases, not sealed attics. We clean every supply and return branch using Rotobrush agitation tools under negative-air extraction, pulling salt-crusted biofilm, shell grit, and mold spores out through Nikro vacuum units with Abatement Technologies HEPA filtration keeping your living space clean during the process. Most Sanibel homes run $380-$650 for a full system cleaning, with larger or more contaminated systems toward the upper end.
Sealing What Rebuild Crews Missed
Cleaning alone won’t fix unsealed joints. After agitation and extraction, we re-seal every collar and connection point in the under-floor chase with mastic and mechanical fasteners rated for salt-air exposure. Then we add a MERV 11 filter at the air handler to catch what the island’s humidity tries to grow back.
Seasonal Home Protocol
Many Sanibel properties sit empty through June-September, peak mold season with minimal air-conditioning. We schedule cleanings before your return, test the system under load, and document static pressure so you know the blower isn’t fighting restricted airflow when you turn the thermostat down.
Trusted Brands We Service in Sanibel
We clean ductwork connected to every major HVAC brand found in Sanibel homes, from original 1980s Trane and Carrier systems still running in Gulf Pines to new Rheem and Lennox units installed during the post-Ian rebuild. For homeowners who want to maintain clean air between visits, we stock Aprilaire media filters, Guardsman UV purification systems, and Abatement Technologies HEPA portable units, with same-week availability for most Sanibel addresses. We don’t upsell equipment you don’t need. We size filtration to your actual system cfm and your family’s air quality goals.
Common Air Duct Cleaning Problems We See in Sanibel Homes
- Post-Ian flex duct failures: Rebuild crews working under emergency timelines left flex duct joints unsealed in under-floor chases. Within one salt-air season, vibration from elevated framing works these collars loose. Homeowners see the new ductwork and assume it’s fine. It rarely is.
- Seasonal mold colonization: A Sanibel vacation home sitting at 82 degrees through August with the AC on minimum creates ideal conditions for biofilm inside duct lining. Owners return in November to musty registers and assume the problem is the carpet.
- Oversized or poorly routed replacement ductwork: Systems installed during the chaotic rebuild phase often had ductwork sized for speed, not for actual cfm requirements. The blower motor strains against excessive static pressure, airflow drops at distant registers, and the lint pathway never fully clears.
- Lizard and insect entry through under-floor gaps: On Sanibel’s elevated stilt homes, disconnected joints in the under-floor chase become highways for wildlife. We find gecko droppings, palmetto bug casings, and once, a small snake curled in a sagging return run off Middle Gulf Drive.

FAQs About Air Duct Cleaning in Sanibel
Yes, and possibly more than the originals. Post-Ian rebuild crews often installed ductwork under emergency conditions with minimal sealing and no seasoning period. We routinely find disconnected joints, unsealed collars, and flex runs sagging against pilings in homes with 2023 replacement ductwork. Call (469) 972-3151 for an inspection and exact quote.
Your system sat through peak mold season with minimal air-conditioning, allowing biofilm to colonize the inside of the duct lining while the house was empty. Sanibel’s 80-90% humidity accelerates this dramatically compared to mainland Lee County. We clean the full system, treat the air handler, and can install a programmable thermostat to maintain dehumidifying airflow during your absence. Call (469) 972-3151 to schedule before your next return.
We clean every supply branch, return branch, and the main trunk line using Rotobrush agitation under negative-air extraction with HEPA filtration. On Sanibel stilt homes, we also inspect and re-seal under-floor joints, test static pressure at the blower, and replace your filter with one sized to your actual system. Before-and-after photos of your own ducts are included. Call (469) 972-3151 for a free estimate.
Sanibel’s barrier-island humidity is consistently 10-15% higher than Cape Coral or Fort Myers, and the salt content in the air accelerates corrosion and mold growth inside ductwork. Our crews use more aggressive agitation settings and longer extraction times to pull salt-crusted biofilm that mainland systems rarely produce. The sealing work afterward is also more critical, unsealed joints fail faster here. Call (469) 972-3151 to discuss your home’s specific conditions.
Yes, sealing is standard on every Sanibel job where we find gaps. We use mastic and mechanical fasteners rated for salt-air exposure, not tape that degrades in six months. This stops lizard, insect, and moisture entry through disconnected collars. The sealing is included in our written scope when needed, never added as a surprise charge. Call (469) 972-3151 for an inspection.
