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.

AfterFast, Reliable Duct Sealing Across Heron Bay
Heron Bay’s golf course ponds and dense Georgia pine corridors create a problem most homeowners don’t notice until their energy bill climbs: the same humid, pollen-heavy air that makes this community beautiful also forces HVAC systems to work harder when ducts leak. We’re the Duct Sealing team at Hollis Air Duct Cleaning, and we’ve sealed ductwork in homes along Heron Bay Parkway, around the clubhouse district, and throughout the wooded lots off Peachtree City Parkway where flexible attic ductwork weeps conditioned air into spaces no one lives in. Dispatch and scheduling run through our Atlanta office, but our crews serve Heron Bay directly. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Heron Bay’s Preferred Duct Sealing Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Heron Bay has grown through one thing: doing what we said we’d do. Our technicians arrive inside the quoted window, price the job in writing before touching anything, and leave the site clean. That’s The Garrison Standard, and it’s how we operate on every call.
Heron Bay homeowners have told us the same story repeatedly. They hired another company that quoted a low price over the phone, then the invoice jumped once the technician was inside. That doesn’t happen here. The price is written down before work starts, and it does not move at the door.
Our response time to Heron Bay is typically same-week scheduling, with background-checked, uniformed technicians who know the area. They understand that homes near the golf course water features face different humidity loads than the drier, more elevated lots toward the community’s eastern edge. That local knowledge changes how we assess leakage points.
Calls are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to get on the schedule.
HVAC Duct Sealing in Heron Bay
HVAC Duct Sealing in Heron Bay addresses a specific problem created by this community’s modern construction and unique environment: conditioned air escaping through gaps, seams, and disconnections in ductwork before it ever reaches your living spaces. Most Heron Bay homes were built from the late 1990s through the 2010s with flexible ductwork routed through unconditioned attics. The materials themselves are sound, but the connections between sections loosen over years of thermal expansion and contraction, especially with Georgia’s hot, humid summers keeping systems running 8 – 9 months annually. A typical HVAC duct sealing job in Heron Bay runs $450 – $850 for a single-zone system, with multi-zone homes ranging $750 – $1,400 depending on accessibility and the extent of leakage found during testing.
How We Test Before We Seal
We pressurize your duct system and measure airflow loss with calibrated equipment before applying any sealant. This gives us a baseline and shows you exactly where your money is going. Many Heron Bay homeowners are surprised to learn they’re losing 20 – 30% of their conditioned air to the attic.
Mastic vs. Tape: What We Use
We apply duct sealing mastic, a water-based compound that remains flexible and won’t degrade like standard foil tape. In Heron Bay’s humid attic conditions, tape adhesive fails within a few years. Mastic lasts the life of the ductwork when applied correctly.
Duct Repair in Heron Bay
Duct Repair in Heron Bay becomes necessary when sealing alone won’t fix the problem: crushed flexible ducts from contractors walking through attics, disconnected trunk lines, or rodent damage in the wooded perimeter lots. The housing stock here is relatively young, so we rarely see the metal fatigue common in 40-year-old systems, but we do find installation shortcuts from the original builders that manifest as collapsed sleeves or improperly supported sagging runs. A typical duct repair in Heron Bay runs $200 – $500 for localized fixes, with extensive re-routing or replacement of damaged trunk lines reaching $600 – $1,200.
Crushed and Collapsed Sections
Flexible ductwork in Heron Bay attics often gets compressed by storage boxes or work crews who don’t know it’s there. A crushed 8-inch flex duct reduces airflow to a trickle. We replace the damaged section with properly supported new material and add protective barriers where needed.
Disconnection at the Plenum
The connection between your air handler and the main trunk line is a common failure point. Thermal cycling loosens the collar, and suddenly your system’s blowing cooled air directly into the attic. We resecure with mechanical fasteners and seal with mastic, not tape.
Trusted Brands We Service in Heron Bay
We stock parts and filtration products from Honeywell, Aprilaire, and Abatement Technologies for Heron Bay homeowners, which means faster turnaround when your system needs components beyond basic sealing materials. Our equipment roster includes Nikro negative-air machines and Rotobrush rotary brush systems for jobs that require Air Duct Cleaning in Heron Bay before sealing can begin. If your dryer vent is contributing to overall system backpressure, we also handle Dryer Vent Cleaning in Heron Bay. Having the right parts on the van means we don’t make two trips, and you don’t take two mornings off work.
Common Duct Sealing Problems We See in Heron Bay Homes
- Pine pollen infiltration through return leaks. During spring, the visible yellow coating on Heron Bay’s outdoor surfaces also pulls into return ducts through gaps near attic access points. Sealing these returns reduces allergen circulation and protects your HVAC filter from premature loading.
- Humidity-driven thermal expansion at flex duct connections. Heron Bay’s lake-effect humidity from the golf course ponds keeps attic moisture levels higher than surrounding areas. This accelerates the loosening of duct clamps and collar connections that sealing must address.
- Multi-zone balancing issues in large homes. The upscale single-family homes common here often have three or four HVAC zones with complex damper systems. Leakage in one zone steals capacity from others, creating hot spots in distant bedrooms that homeowners blame on the wrong equipment.
- Original builder shortcuts at trunk line splits. Homes built during the 2000s construction boom sometimes have Y-splits sealed with tape rather than mastic, or flex ducts pulled tight without proper slack. These installations fail predictably, and we see them regularly in the 1990s – 2000s builds near the community’s original entrance.
Pricing for Duct Sealing in Heron Bay, GA
Most Heron Bay homeowners pay between $450 and $850 for single-zone duct sealing, with multi-zone systems running $750 – $1,400. Duct repairs range from $200 for localized fixes to $1,200 for extensive trunk line work. What moves you within these ranges: the number of HVAC zones, attic accessibility (some Heron Bay homes have tight scuttle entries that slow work), and whether we find damage requiring repair before sealing can be effective. We also offer Duct Sealing in Heron Bay as part of bundled service with air duct cleaning, which can reduce overall cost when both are needed. Every job gets a written price before work starts, and that price does not change. Estimates are free. Call (361) 326-5060.

Yes, we seal ducts throughout the community, including homes near the golf course clubhouse, the wooded lots along Peachtree City Parkway, and the newer sections toward the eastern perimeter. Each area presents slightly different attic access and humidity conditions, which we account for in our assessment.
We don’t classify duct sealing as an emergency service, but our phones are answered by a live person 24/7, and we will schedule urgent appointments for situations like complete disconnection where your system is non-functional. For true HVAC emergencies, we recommend contacting your heating and cooling contractor first, then calling us for the ductwork portion.
Pricing is consistent across our service area, though Heron Bay’s larger homes with multiple zones often land in the upper half of our range compared to smaller homes in more urban parts of metro Atlanta. The work itself is priced by system complexity and accessibility, not by ZIP code.
Every duct sealing job is covered by our 365-Day Done Right Promise. If the seal fails or leakage returns within a year, we come back and make it right at no charge, including a free second visit. This is backed in writing on every job, not a verbal assurance.
