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

We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Clayton County is built on showing up when we said we would and leaving the site clean. Irondale homeowners have told us they chose us because our technicians arrive uniformed and background-checked, and because our 365-Day Done Right Promise is actually written down, not just mentioned over the phone. We understand how Irondale’s mix of mid-century ranch homes and newer construction creates different sealing challenges, and we price accordingly before we touch anything. Our phones are answered by a live person 24 hours a day, 7 days a week, so you’re not waiting until Monday to schedule. Dispatch and scheduling are coordinated from our Atlanta office, with crews serving Irondale locally.

Duct Insulation in Irondale

Duct Insulation in Irondale is often the missing piece when homeowners have already sealed their ducts but still can’t get even temperatures room to room. The humid subtropical climate here means condensation builds on cold duct surfaces in summer, especially in unconditioned attics and crawlspaces where Irondale’s older ranch homes tend to run their ductwork. That moisture soaks standard fiberglass insulation, compresses it, and turns it into a mold habitat. A typical duct insulation job in Irondale runs $400 – $900 depending on linear footage and whether we need to remove degraded material first.

When Insulation Fails Before the Duct Does

In neighborhoods near the South River, we regularly pull back insulation that has been wet multiple times from crawlspace flooding after heavy rains. The duct metal underneath might be intact, but the insulation is doing more harm than good, harboring mildew and reducing R-value to nearly nothing. We replace it with closed-cell foam or properly sealed fiberglass wraps rated for high-humidity zones.

Matching Insulation to Your System’s Age

Original ductwork in Irondale’s 1960s and 1970s ranch homes was often insulated to a lower standard than today’s code requires. We measure what you have, explain the gap in plain terms, and give you a written price to bring it up to modern standards without pushing equipment you don’t need.

HVAC Duct Sealing in Irondale

HVAC Duct Sealing in Irondale stops the conditioned air you’re paying for from escaping into spaces where it does no good. Our crews use professional-grade mastic compounds and metal-backed tape, not the hardware-store foil tape that peels off within a season in Georgia humidity. We pressurize the system, measure leakage with a duct blaster, and show you the before-and-after numbers. A typical residential HVAC duct sealing job in Irondale runs $350 – $750 for a single system, with larger homes or multiple zones running higher.

Leak Detection Before Sealing

We don’t guess where your ducts are leaking. Our technicians run a negative-air test to pinpoint disconnected joints, crushed flex runs, and gaps around plenums. In Irondale’s older homes, we often find the original duct tape has turned to dust, especially on return air pathways in hot attics.

Sealing After Flood Exposure

Homes in low-lying Irondale neighborhoods that have seen crawlspace flooding sometimes need sealing combined with cleaning and disinfection. We handle the full scope, and we also provide Air Duct Cleaning in Irondale when mold or mildew has colonized the interior surfaces.

Trusted Brands We Service in Irondale

We stock parts and sealing materials from Aprilaire, Abatement Technologies, and Guardsman, the same filtration and ductwork brands commercial crews specify. That means when your Irondale home needs a plenum repair, a transition rebuild, or a complete flex-duct replacement tied into sealing work, we’re not ordering parts and making you wait. Our Rotobrush rotary brush systems and Nikro negative-air machines are on the truck for jobs that need cleaning before sealing. We explain what brand we’re using and why, in plain terms, before we start.

Common Duct Sealing Problems We See in Irondale Homes

• Original duct tape crumbling in attics. The ranch homes built across Irondale in the 1960s and 1970s often have decades-old foil tape that has dried out and detached. We remove the residue and seal with mastic that flexes with temperature swings and won’t degrade in Georgia heat.
• Flex duct crushed or sagging in crawlspaces. After repeated flooding near the South River, flex duct hangs lower than designed, kinking at bends and tearing at connections. We support it properly or replace it with hard pipe where the location demands it.
• Return air pathways pulling from wall cavities. In some Irondale subdivisions, builders took shortcuts and used unsealed wall bays as return channels. That pulls attic dust, insulation fibers, and humidity directly into your breathing air. We build proper return ducting and seal it tight.
• Supply registers leaking behind drywall. The gap between the duct boot and the finished wall is rarely sealed in older construction. Conditioned air leaks into the wall cavity, and attic air gets pulled back in. We foam and tape these junctions on every sealing job.
