Why Hollis Air Duct Cleaning Is Bloomingdale’s Preferred Duct Sealing Company

We’ve been serving Florida homeowners since 2004 as part of the Garrison Partners family, and our Bloomingdale customers come back because we write the price down and don’t move it at the door. Our Duct Sealing team is held to The Garrison Code: arrive inside the quoted window, uniformed and background-checked, leave the site clean.

Bloomingdale’s housing stock is specific – mostly 1980s – 2000s tract homes with flexible ductwork in unconditioned attics, and that matters when we’re quoting a seal job. A tech who treats this like any other Tampa suburb will miss the water-table issues. We don’t.

Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No “we’ll call you back Monday.” When you’re smelling musty air on a Saturday evening, someone picks up.

Every repair is covered by our 365-Day Done Right Promise. If the seal fails or the odor returns within a year, we come back and make it right at no charge, including a free second visit. That’s written on every job, not implied.

HVAC Duct Sealing in Bloomingdale

HVAC Duct Sealing in Bloomingdale is a moisture-control job as much as an air-loss fix, and that’s a distinction you won’t find in drier, higher-ground markets. Most Bloomingdale homes sit on sandy soils with a high water table, and that ground moisture pushes into slab-on-grade construction even in 1990s-era builds. The result: musty odors and pool-style condensation inside flex runs before any visible mold appears. Sealing here must be paired with moisture verification, or the problem returns between cleanings.

Our process starts with a camera inspection of the full duct system. We pressurize the lines and use smoke testing to find leaks at the air handler collar, register boots, and any crushed or disconnected flex runs. Then we seal with mastic – a water-based sealant that remains flexible – and mechanical fasteners at stress points. We don’t use foil tape alone in Bloomingdale attics; the adhesive cooks off in summer heat and humidity.

A typical HVAC duct sealing job in Bloomingdale runs $450 – $850 for a single-system home, depending on accessibility and how many runs need re-support or replacement. Two-story homes with ductwork in a hot garage attic tend toward the higher end. We write the price before we start, and it doesn’t change.

What We Find in Bloomingdale Attics

Mastic and foil-tape seals fail at the air handler collar and register boots in unconditioned attics where summer temperatures and year-round humidity degrade adhesives. We remove the old failing material, clean the surface, and apply new mastic with a reinforcing mesh at joints that flex when the system cycles.

Moisture Verification After Sealing

Because Bloomingdale’s ground-driven moisture can re-enter through slab penetrations and wall cavities, we verify humidity levels at the return plenum and supply registers after sealing. If readings stay elevated, we flag it and explain your options. Sealing alone won’t fix a moisture source.

Duct Repair in Bloomingdale

Duct Repair in Bloomingdale often means fixing what decades of attic heat and humidity have damaged, not just patching a single leak. The 1980s – 90s flex duct in most local homes becomes brittle, collapses where supports have failed, or pulls loose at the air handler when tape adhesive degrades. We’ve also found original ductwork that was undersized from the start – a common issue in rapid-development subdivisions – which strains the blower and exaggerates every leak.

On a 1991 slab-on-grade house off Bell Shoals Road, our tech ran camera inspection down the original flex return and found it crushed flat where an attic truss had settled – the blower motor was pulling makeup air through a closet door gap instead of the return. We performed source removal under negative pressure with HEPA filtration, then sealed and re-supported the return run with new flex and mastic at the air handler collar. Static pressure dropped and the musty odor the homeowners blamed on “the AC” cleared within two days.

Duct repair in Bloomingdale typically runs $350 – $750 for single-run replacement and re-sealing, or $800 – $1,400 if multiple runs are crushed, disconnected, or need upsizing to correct original undersizing. We photograph before and after, and you see the images with the written price before we proceed.

Crushed and Disconnected Flex Runs

Original flex duct in Bloomingdale’s 1980s – 90s homes often sags where straps have failed, gets crushed by storage items in attics, or pulls loose at boots when tape gives way. Sealing visible joints won’t fix a disconnected supply dumping conditioned air into the attic. We locate these with camera and pressure testing, then re-support with proper hangers.

Post-Storm Humidity Damage

After summer storms knock out power, interior humidity spikes while the system is off. If ducts were sealed but not moisture-verified, microbial growth returns and the seal job looks like it failed. We check for this scenario specifically in post-storm service calls.

Trusted Brands We Service in Bloomingdale

We stock parts and sealing materials from Aprilaire, Abatement Technologies, and Guardsman for Bloomingdale jobs, and our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines. That means when we find a failed seal or crushed run during your service call, we’re not ordering parts for next week. We carry mastic, reinforcing mesh, flex duct in standard diameters, and register boots for the common sizes in local tract homes. For filtration upgrades after sealing, we source Honeywell and Aprilaire media filters sized to your return. Fast turnaround matters when your AC is running 10 hours a day in July and every day of delay shows up on your FPL bill.

Common Duct Sealing Problems We See in Bloomingdale Homes

• Adhesive failure at air handler collars. The mastic and foil tape applied when your home was built has cooked in attic heat for 30-plus years. It peels, cracks, and lets conditioned air leak into the attic. We scrape to bare metal and reseal with fresh mastic and mechanical fasteners.
• Crushed flex returns in original 1980s – 90s systems. Undersized returns were common in rapid-development subdivisions. Over time, the flex gets pinched by truss settlement or storage weight. The blower starves for air and pulls from wall cavities, garage, or attic instead.
• Ground moisture entering slab-on-grade duct chases. Bloomingdale’s high water table pushes moisture through concrete penetrations. Even sealed ducts develop musty odors if we don’t verify and address humidity at the source. This is why our seal jobs include moisture readings.
• Post-hurricane humidity spikes in unsealed systems. After power outages, humidity soars inside ductwork. If joints were already leaking, microbial growth accelerates. We see peak demand calls 2 – 4 weeks after major storms, and the fix is sealing plus verification, not just cleaning.
