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.

HVAC cleaning in Sanibel typically runs $285 to $685 for a full system cleaning, depending on home size and how much buildup has accumulated in the ductwork and coils.

Sanibel homeowners choose Cardinal because we’re one of the only duct cleaners on the island that shows you proof of the work.

That’s a full year of coverage on every booking, without exception.

Furnace Duct Cleaning in Sanibel
Furnace duct cleaning in Sanibel homes is about removing years of lint, drywall dust, and pet dander from the supply and return lines that carry conditioned air through the house. Many homes on Sanibel weren’t built with central AC – they were built with electric furnaces or heat strips that share ductwork with the cooling system, so the same ducts that push warm air in January are carrying cold air in July. When those ducts clog, the system works harder and the air smells stale. A standard furnace duct cleaning on Sanibel runs $285 to $485 for a typical 1,500 to 2,500 square foot home.
What The Job Actually Involves
We connect a negative-pressure extraction unit to the trunk line – that means the loosened debris goes straight into the vacuum, not back into your living room. Then we agitate each duct run with brush systems to break loose caked-on buildup, and photograph the registers before and after from the same angle. You see exactly what came out.
When Sanibel Homeowners Should Schedule It
If you’ve had hurricane remediation, drywall work, or new flooring installed in the last few years, schedule furnace duct cleaning. Construction dust settles in ducts and recirculates every time the blower kicks on. If you can’t remember the last cleaning, it’s overdue. If you can pull a register and see gray film on the metal, call us.
AC Coil Cleaning in Sanibel
AC coil cleaning in Sanibel hits different than the mainland because the island’s salt air accelerates corrosion and biological growth on evaporator coils. When the coil gets coated with grime, it stops pulling heat from the air efficiently, so your AC runs longer, your humidity climbs, and your electric bill rises. We clean coils with coil-specific treatments that break down the biofilm and corrosion without damaging the fins. AC coil cleaning in Sanibel typically runs $185 to $395 depending on access and coil condition, and it’s often bundled with a full HVAC Cleaning at a better rate than doing them separately.
Evaporator Coil Deep Clean
The evaporator coil sits inside the air handler, where humid island air passes over it constantly. That’s why Sanibel coils grow more mold than Fort Myers coils. We access the coil, apply a foaming treatment, and rinse it so airflow restores to spec.
Condenser Coil Wash and Fin Treatment
The outdoor condenser coil takes direct salt spray on Sanibel. We wash the fins with low-pressure water and apply a corrosion-inhibiting treatment after. It’s not glamorous, but it extends the life of a unit that’s getting hammered by Gulf air every day.
Trusted Brands We Service in Sanibel
We service and clean systems from every major manufacturer you’ll find on Sanibel: Carrier, Trane, Rheem, Lennox, Goodman, and more. For filtration, we stock and recommend Honeywell, Aprilaire, and Nikro products, including MERV 11 and MERV 13 media filters suited for the island’s humidity and pollen load. We keep common filter sizes and coil treatments on the truck, so a Sanibel stop on Periwinkle Way or Rabbit Road doesn’t mean waiting for parts to ship from Fort Myers. If your system uses a specialty filter, we’ll tell you before the cleaning starts and quote the replacement honestly.
Common HVAC Cleaning Problems We See in Sanibel Homes
– Elevated piling houses with exposed duct runs trap condensation and rust far more often than slab homes. The humid air underneath the house creates a thermal differential that causes moisture inside the duct insulation, which leads to mold you can smell the moment the blower spins up.
– Post-Ian rebuilds with new drywall often have construction dust caked inside brand-new ducts. Builders don’t always cover registers during finishing work, so drywall sanding dust settles in the ductwork before you ever move back in.
– Salt air corrosion on outdoor condenser coils is a year-round issue on Sanibel, not just during storm season. Coils corrode faster within a few blocks of the beach, especially along West Gulf Drive and Middle Gulf Drive.
– Short cycling from clogged filters happens more on the island because the AC runs nearly every month of the year. A dirty filter makes the system work harder, pulls more humid air through the evaporator coil, and accelerates buildup inside the air handler.

FAQs About HVAC Cleaning in Sanibel
How often does HVAC cleaning actually need to happen in a Sanibel home?
Every 3 to 5 years for most Sanibel homes, though post-rebuild homes with recent construction should schedule one within the first year. If you have pets, severe allergies, or live within a few blocks of the beach where salt and sand blow constantly, lean toward every 2 to 3 years. If your ducts were last cleaned over 5 years ago, it’s time. Call (737) 727-2314 and we’ll help you figure out where your system stands.
Do you charge per vent or one flat price?
One flat price per system, always. We don’t charge per vent because it invites games, and on Sanibel’s mix of small piling houses and larger rebuilds, it overcharges some homeowners and under-delivers for others. You’ll get a written price for the entire system before any work starts, and that number is what you pay. No add-ons when the tech arrives.
Will you show me proof of what you removed?
Yes. Before-and-after photos from inside your own ducts, taken from the same camera angle, are included with every HVAC cleaning in Sanibel. You’ll see registers, trunk lines, and coil surfaces before we start and after we finish. If we say buildup was removed, you’ll have photos that show it. That’s the whole point of the Relay Standard booking experience.
Do you offer same-day HVAC cleaning in Sanibel?
We don’t promise same-day service because proper HVAC cleaning on the island takes time – typical jobs run 3 to 6 hours depending on system size and buildup. We schedule by appointment and give you a live trackable arrival window so you’re not stuck waiting around. Call (737) 727-2314 and we’ll get the next available appointment locked in.
What does the process actually involve – is it just vacuuming the vents?
No, it’s a full negative-pressure extraction process. We connect a HEPA-filtered vacuum unit to the trunk line to pull air through the entire system, then agitate each duct run with rotary brushes to loosen caked-on debris. The loosened material gets sucked straight to the vacuum, not blown into your rooms. We also clean the blower, evaporator coil, and air handler compartment, then photograph everything. It’s a real cleaning, not a tick-box service.
One Flat Price, Photo Proof, Done Right
Sanibel’s building stock mixes 1960s-era elevated island cottages with post-Ian rebuilt homes on the same street, so a single route often requires two completely different duct-cleaning setups on the same day. One crew might be cleaning a compact piling-house system on East Gulf Drive while another handles a brand-new post-rebuild layout near Sanibel-Captiva Road. That variance in home age and rebuild status is what dictates how we price and scope HVAC cleaning here, not a one-size-fits-all chart. We were out on Middle Gulf Drive at an elevated cottage where the owner kept noticing a musty smell from the supply and return ducts whenever the AC kicked on. Our tech ran a camera inspection through the trunk line and found a heavy lint pathway and debris clogging the air handler compartment, so we set up negative pressure with the Rotobrush and HEPA filtration, used agitation tools on the registers, and pulled the buildup out to source. After cleaning we photographed the before-and-after from the exact same camera angle and handed the homeowner the images along with a MERV rating recommendation for their filter.
That’s what an honest HVAC cleaning in Sanibel looks like. One flat price per system, agreed before we start. Before-and-after photos of your own ducts, not a demo reel. And if the work isn’t right within 365 days, we return and correct it at no charge. Call (737) 727-2314 for a free estimate, or to ask Omar Haddad a direct question about your system.
