Why Hollis Air Duct Cleaning Is Bonita Springs’s Preferred Duct Sealing Company

We’ve been part of the Garrison Partners family since 2004, and our Duct Sealing in Bonita Springs work follows The Garrison Standard: arrive inside the window, price in writing, complete the job by the book, leave the site clean. That standard matters here because Bonita Springs properties are often managed remotely. A property manager in Chicago needs a crew that doesn’t need hand-holding, and a homeowner in Pelican Landing needs technicians who understand HOA access rules for common mechanical chases.

Our technicians are background-checked and uniformed. You know who’s arriving before they knock. Phones are answered by a live person 24 hours a day, 7 days a week, so a property manager coordinating a turnover window doesn’t get stuck in voicemail. Every repair is backed by our 365-Day Done Right Promise: if the seal fails or the musty odor returns within a year, we come back at no charge, including a free second visit. No negotiation, no runaround.

We don’t chase the lowest teaser price. We give one flat price per system, agreed before work starts, and that price doesn’t move when the van is in your driveway. In a market full of coupon offers that balloon once the technician is inside, our customers tell us the written price is why they call us back for the next vacancy cycle.

HVAC Duct Sealing in Bonita Springs

HVAC Duct Sealing in Bonita Springs is usually about stopping air migration through failed seals in shared chases, not about patching a single visible leak. The villas and mid-rise condos built here from 1980 to 2000 often have compact mechanical chases with short, flat-rated duct runs. When the seal at a collar or plenum fails, conditioned air doesn’t just leak into the attic; it migrates into the chase itself, pressurizing the cavity and pushing musty, humid air into adjacent units. That’s why a property manager gets the “smell in the neighbor’s unit” call after a summer vacancy, not just a complaint from the empty one.

A typical HVAC duct sealing job in Bonita Springs runs $280 – $650 for a condo or villa system and $450 – $1,200 for a single-family home with longer runs and more joints. The price varies with access difficulty, whether we need to coordinate with an HOA for common-area entry, and whether the original flex duct needs replacement rather than resealing.

Camera Inspection Before Sealing

We run a borescope through every accessible section before we quote. In Bonita Springs, this step is non-negotiable. We’ve found crushed flex runs hidden behind air handlers, disconnected collars leaking into chases for years, and mildew on insulation that tape-over would only trap. The camera shows us what we’re sealing and what we’re sealing around.

Mastic Sealing and Static Pressure Testing

We seal with mastic, not tape, because tape fails within one rainy season in a humid chase. After sealing, we test static pressure at the air handler. A sealed system with a failing blower motor runs high static and pulls new leaks within months. We check the motor and the pressure because sealing without verifying the system is a temporary fix.

Duct Repair in Bonita Springs

Duct Repair in Bonita Springs often means replacing original 1980s – 1990s flex duct that has collapsed, torn at the collar, or degraded past the point where sealing helps. The subtropical climate here, with summer dew points above 70°F and a May – October rainy season, accelerates that degradation. Condensation forms on cold supply runs whenever the A/C cycles off during a vacancy, and the moisture works under existing seals, saturating the flex backing and the insulation around it.

Duct repair costs in Bonita Springs typically fall between $380 – $950 for partial replacement of flex runs in a villa or condo, and $800 – $1,800 for full replacement in a single-family system with longer hard-ducted sections. If we’re already on site for a cleaning, adding repair work is priced separately in writing, not tacked on as a surprise.

Crushed Flex and Disconnected Collars

In Pelican Landing we opened a 1994 villa’s return plenum and found the original flex run crushed flat behind the air handler and a disconnected collar leaking into a shared chase; a camera inspection showed mildew on the insulation just past the collar. We set the space under negative pressure, ran agitation tools through the supply and return ducts with HEPA filtration at the unit, re-sealed the collar with mastic, replaced the crushed flex with a hard-ducted run, and treated the plenum with antimicrobial. The musty odor stopped returning on the next vacancy cycle.

Hard-Ducted Replacement in Shared Chases

When flex duct in a shared chase has failed repeatedly, we often recommend replacing it with hard duct. The material costs more upfront, but it doesn’t collapse, doesn’t tear at collars, and doesn’t hold moisture the way flex insulation does. In Bonita Springs’s humid chases, that’s a permanent fix, not a cycle of re-sealing every two years.

Trusted Brands We Service in Bonita Springs

Our Duct Sealing crews carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, and we stock filtration and sealing products from Honeywell, Aprilaire, and Guardsman. For Bonita Springs customers, that means we don’t wait on parts shipments from Tampa or Miami. If a villa in Bonita Bay needs a specific collar size or a condo on Imperial Parkway requires antimicrobial treatment that matches the HOA’s approved chemical list, we usually have it on the van. The same tools commercial crews use on mid-rise buildings are what we bring to a single-family job, because the chase construction here is often closer to commercial than to typical residential.

Common Duct Sealing Problems We See in Bonita Springs Homes

• Original flex duct collapses in shared chases. The 1980s – 1990s flex installed in Bonita Springs villas was rated for lighter loads than what Florida humidity imposes. It flattens behind air handlers, tears at metal collars, and leaks into the chase for years before anyone smells it.
• Tape seals fail within one rainy season. A previous handyman or even an HVAC contractor may have taped over a leak. In a humid Bonita Springs chase, that adhesive degrades fast. We remove the tape and seal with mastic, which flexes and bonds in damp conditions.
• Condensation grows mildew under existing seals during summer vacancies. When a Bonita Springs condo sits empty with the A/C set high or off, dew point hits inside the ductwork. Mildew blooms on the insulation, under the seal, and re-contaminates the system every time the unit cycles. Cleaning and treating the plenum is part of the real fix.
• HOA turnover schedules rush sealing without static pressure checks. Property managers need units ready fast. A crew seals the obvious leak, leaves, and the system runs high static because the blower motor was already struggling. New leaks appear at the air handler within months. We test pressure before we close up.
