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.
Air Duct Cleaning Company in Keystone, FL
Air duct cleaning in Keystone, FL typically costs $350 – $650 for a whole-home system and is scheduled by appointment, not dispatched same-day. Homes here face a specific set of problems: salt-laden gulf air, year-round humidity above 60%, and slab-on-grade construction that puts ductwork either in the attic or buried under concrete. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and our crews serve Keystone from our South Florida scheduling office. Call (361) 326-5060 for a free estimate.
Why Keystone Homes Are Different
Keystone sits on the Tampa Bay coast where the gulf water stays 70 – 80°F most of the year, and that warmth pumps humidity into every attic and crawl space. Most houses are 1980s – 2000s single-story ranches or Mediterranean-style builds on slab foundations, many on well water and septic. The ductwork is almost always flex duct in the attic or hard pipe under the slab, often still wrapped in original R-4 or R-6 insulation that’s past its useful life.
The coastal location means we see conditions inland Tampa suburbs don’t. Salt air corrodes metal fittings in attic systems. Rainy-season downpours push moisture into duct interiors where it sits, and within a single season that moisture feeds biological growth. After named storms or tropical systems, the calls change character entirely. We regularly open attic flex runs or slab chases and find saltwater-borne silt and mold that has ruined the ductwork. Those jobs aren’t cleanings; they’re full replacements. That distinction matters for pricing, scheduling, and what a homeowner should expect when we arrive.
Our Main Keystone Services
Keystone homeowners call us for three jobs, each with its own page and its own set of local considerations.
Air Duct Cleaning in Keystone
We clean supply and return ducts with a rotary brush system from Rotobrush and negative-air machines from Nikro that pull loosened debris out of the system rather than pushing it deeper. In Keystone, the job often starts with an attic inspection because flex duct runs there take the worst of the humidity and salt air. We check for insulation collapse, fitting corrosion, and biological growth before we quote. Air Duct Cleaning in Keystone covers the full process, what we find in local homes, and how we price it.

Dryer Vent Cleaning in Keystone
Dryer vent cleaning in Keystone runs into two local problems: longer vent runs common in ranch-style layouts, and lint packed hard by humid air that keeps it damp and clinging. We use rotary brushes and high-velocity air tools to clear the full run to termination, then verify airflow with a meter. Blocked vents are a genuine fire hazard, and in humid coastal conditions they clog faster than inland. Dryer Vent Cleaning in Keystone has the details on our process and what we charge.

Duct Sealing in Keystone
Duct sealing with mastic closes the leaks that pull attic air into your living space. In Keystone, that matters more than most places because attic temperatures hit extreme highs and the humidity load is constant. We seal joints, seams, and connections, then test with a pressure gauge to confirm the reduction in leakage. Homes with under-slab ductwork need a different approach; we assess whether sealing is practical or if replacement makes more sense. Duct Sealing in Keystone explains both methods.
