Duct Repair & Replacement in Jacksonville, NC

We begin with a comprehensive assessment. Our technicians inspect accessible ductwork in your attic, crawlspace, basement, and behind walls. We look for visible damage—tears, dents, corrosion, disconnections, kinks, insulation deterioration. We check duct routing for inefficiencies (extremely long runs, unnecessary bends, undersized sections).

We use video camera inspection to examine ductwork you can’t see. A fiber-optic camera travels through the ducts, revealing internal damage, sags, obstructions, and leaks. You’ll see the footage so you understand what we find. Then we perform duct leakage testing using a blower door and duct testing equipment to quantify how much air is escaping.

• We measure static pressure throughout the system to identify problem areas
• We check duct sizing against your furnace and AC unit specifications
• We identify where insulation is missing or damaged
• We document all findings with photos and measurements

Based on inspection results, we recommend repair vs. replacement and prioritize work by impact. A small leak in an attic duct loses a lot of air, so we seal that first. A kinked flexible duct in a closet might be strangling airflow to a bedroom, so we replace that section next. A disconnected return duct means your furnace is pulling unconditioned air from your attic, so we reconnect it.

We discuss options and costs: patching a small hole costs far less than replacing a full run of ductwork, but sometimes replacement is more durable. We also recommend upgrades—adding insulation to improve efficiency, rebalancing duct sizing to improve airflow distribution, extending ducts to underserved rooms.

• We explain the efficiency and comfort gains you’ll realize from each repair
• We discuss multi-phase approaches if budget is tight (seal leaks now, add insulation later, replace aging sections next year)
• We provide upfront pricing so there are no surprises

We perform duct repairs using industry-best methods. Small tears and holes are sealed with mastic sealant (a rubber-based adhesive more durable than duct tape). Seams are sealed where ducts connect. Kinked flexible ducts are replaced with new flexible or rigid ducts. Corroded metal ducts are replaced. Disconnected ducts are reconnected and sealed.

For replacement work, we run new ductwork to code (properly sized, insulated, and supported). We route ducts efficiently to minimize bends and length. We ensure return ducts pull from your living space, not your attic or crawlspace. We balance the system so air reaches every room adequately.

• We clean ducts during repair if insulation is damaged and debris is exposed
• We upgrade to rigid metal ducts where durability matters (high-use areas, areas subject to temperature extremes)
• We add or upgrade insulation in unconditioned spaces (attics, crawlspaces)
• We secure ducts with proper supports and hangers to prevent sagging and damage

Before we call the job done, we verify your ductwork is sealed, properly insulated, and delivering air to every room. We retest system pressure and leakage to confirm improvements. We check temperatures in every room to verify airflow distribution. We run your furnace and AC through a full cycle to listen for noise (which may indicate remaining issues) and confirm normal operation.

• We do a final video inspection of sealed sections to confirm sealant applied correctly
• We measure airflow at every register to confirm balanced distribution
• We pressure-test the system again and compare to the starting baseline—you’ll see the improvement
• We provide a written report of work completed and performance gains

Once your ducts are repaired, maintaining them prevents future problems. We suggest annual HVAC maintenance that includes checking for new leaks. Over time, seals can degrade and ducts can develop new issues, but regular inspection catches them early.

• We recommend routine furnace filter replacement (an often-overlooked factor in duct health)
• We advise on protecting ducts in attics from damage (ensuring they’re not crushed by insulation or stepping)
• We schedule follow-up inspections if you want to monitor long-term performance
• We’ll recommend additional work (insulation upgrades, duct extension to new spaces) as your needs evolve
