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 Sealing in Hilliard
Air Duct Sealing in Hilliard is often misunderstood. Most homeowners think it’s only for old, leaky systems. In Hilliard, we regularly seal ducts in homes built after 2000 because the problem isn’t age, it’s what the builder left behind.
Here’s what the job actually involves. We pressurize your duct system to locate leaks, then seal joints, register boots, and connections with mastic or metal-backed tape rated for HVAC use. After sealing, we verify with a second pressure test. The goal is simple: air you’ve already paid to heat or cool should reach the rooms you actually live in, not your attic or crawl space.
A typical Air Duct Sealing job in Hilliard runs $450 – $950 for a whole-house system, depending on duct accessibility and how many leaks we find. Homes with finished basements or sealed crawl spaces take longer to access, which pushes toward the higher end. We give you a written price before any work starts, and that number does not move at the door.
When New Homes Need Sealing Most
Hilliard’s post-2000 subdivisions like Heritage Preserve and Alton Darby Creek use flexible, sealed ductwork that hides construction debris – drywall dust, sawdust, even soda cans – making a brand-new home a top candidate for duct sealing and Hilliard Dryer Vent Cleaning far earlier than owners expect. The flexible duct is crimped and taped at joints that often aren’t sealed to NADCA standards. Dust migrates through these gaps, past the air handler, and into your living space for months after move-in.
The Older Ranch Problem
Near historic downtown Hilliard, original 1950s-70s galvanized steel ducts have decades of rust and debris accumulation. Sealing these without first removing the load traps pollutants behind the seal. We always inspect with a camera before sealing any older system.
Duct Sealing Services in Hilliard
Duct Sealing Services in Hilliard from Hollis cover the full scope: leak detection, manual sealing of accessible joints, mastic application at boots and plenums, and post-seal pressure verification. We also coordinate source removal when ducts are loaded with construction debris or decades of accumulation.
Our Duct Sealing team uses professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies. The rotary brush system agitates debris loose while the negative-air machine pulls it out under HEPA filtration. This matters in Hilliard because construction dust is fine enough to pass through standard filters and recirculate indefinitely.
Most Duct Sealing Services in Hilliard fall between $450 – $950 for a complete residential system. If we need to access ducts through finished drywall or sealed soffits, we’ll tell you before we cut anything. The price is written down before work begins.
Construction Debris Source Removal
In a brand-new Heritage Preserve build, our tech pulled a camera inspection on the supply and return ducts and found drywall dust coating the flexible duct walls so heavily it was choking airflow and pushing the blower motor past its rated static pressure. We ran agitation tools under negative pressure with HEPA filtration, then sealed every register boot and joint to stop the construction dust from re-entering the living space. The homeowners said the fine white film on their furniture stopped within a week.

Pressure Testing and Verification
We don’t guess. Before and after sealing, we measure static pressure and airflow at each register. Hilliard’s humid summers and dry winters already stress HVAC systems; we make sure your blower isn’t working harder than it should because air is escaping into your attic.

Common Duct Sealing Problems We See in Hilliard Homes
- Builder-grade flexible ductwork in newer subdivisions with unsealed joints. Heritage Preserve and Alton Darby Creek homes often have flexible duct installed with tape that fails within the first two years, letting drywall dust migrate out of the ducts and into the air handler long after move-in.
- Homeowners skipping source removal on “new” ducts. In newer Hilliard subdivisions, owners assume new ducts are clean and seal over debris that keeps blowing into the house. The seal holds; the dust just finds another path.
- Sealing older galvanized systems without inspection. Ranch homes near historic downtown Hilliard have original steel ducts that have rusted and loaded up with decades of debris. Seal these blind and you trap pollutants behind the mastic.
- Humid summer mold and dry winter dust cycling. Hilliard’s four distinct seasons mean your HVAC runs hard year-round. Humid summers breed mold in unsealed crawl space ducts; cold dry winters pull dust through every gap. Sealing breaks both cycles.
Pricing for Duct Sealing in Hilliard, OH
A typical whole-house duct sealing in Hilliard runs $450 – $950. Small homes with accessible basements and minimal leaks land near the lower end. Larger homes with finished basements, sealed crawl spaces, or extensive flexible duct networks in subdivisions like Heritage Preserve trend toward $850 – $950 because of access time and joint count.
What moves the price: duct material (flexible duct takes longer to seal properly than rigid metal), accessibility (crawl space vs. full basement), pre-existing debris load (source removal adds $200 – $400), and whether we need to cut access panels in finished surfaces. We tell you all of this before we start. The price is written down. It does not change at the door.

FAQs About Duct Sealing in Hilliard
Builder-grade flexible ductwork in Alton Darby Creek is often installed with joints that aren’t sealed to residential standards, and construction debris frequently remains inside the ducts at handover. Drywall dust and sawdust migrate through these gaps into your air handler and living space for months after move-in. Call (361) 326-5060 and we’ll camera-inspect your system to show you exactly what’s in there.
Sealing alone won’t remove dust that’s already inside your ducts, but sealing after proper source removal stops construction debris from re-entering your living space. In Heritage Preserve homes, we typically recommend agitation cleaning under negative pressure first, then sealing every boot and joint to lock the remaining particles out of your airflow. The homeowners we did this for saw the white film on their furniture stop within a week.
Yes, but only after camera inspection and likely source removal. Original galvanized steel ducts in older Hilliard ranches often have decades of rust and debris accumulation. Seal over that load and you trap pollutants behind the mastic. We inspect first, clean if needed, then seal. The written price covers whichever steps your system actually needs.
For most Hilliard homes after duct sealing, we recommend a MERV 11 filter from Aprilaire or Guardsman, which captures construction dust, pollen, and mold spores without overloading your blower motor. Higher MERV ratings restrict airflow and can actually damage sealed systems if the blower isn’t rated for the static pressure. We’ll check your system’s specs and recommend the right match.
Hilliard’s four distinct seasons stress HVAC systems year-round: humid summers can breed mold in unsealed crawl space ducts, while cold, dry winters increase dust circulation through every leak. Proper sealing blocks both moisture intrusion in summer and dust infiltration in winter, reducing the load on your system in every season. After sealing, most Hilliard homeowners see more consistent room temperatures and lower utility bills within the first billing cycle.
