Stop losing conditioned air through leaky, damaged, or poorly designed ducts. Professional ductwork services for better comfort and lower energy bills.
Most homeowners focus on their furnace or air conditioner when something feels off with their heating and cooling — but the ductwork that delivers conditioned air throughout your home is just as critical. According to ENERGY STAR, the average home loses 20-30% of conditioned air through duct leaks, holes, and poorly connected joints. That means up to a third of the money you spend on heating and cooling is literally being blown into your attic, crawl space, or walls. Frost Fire Heating and Cooling provides professional ductwork repair, sealing, replacement, and new installation throughout Clayton, Raleigh, Durham, Garner, and the Triangle area.
North Carolina homes face unique ductwork challenges. Many homes in Clayton, Raleigh, and Durham were built with ductwork running through unconditioned attics where summer temperatures can exceed 140°F. Poorly insulated or leaking ducts in these spaces work against your HVAC system, forcing it to run longer and harder — driving up energy bills and accelerating wear on expensive equipment. Older homes may have undersized ducts, flex duct that has sagged and kinked over time, or original sheet metal with decades of accumulated dust and deterioration.
Frost Fire's ductwork services address every aspect of your air distribution system. Whether you need a few leaking joints sealed, a section of crushed flex duct replaced, or a complete duct system designed and installed for a home addition or renovation, our licensed HVAC technicians deliver quality workmanship with the same transparent, fair pricing you expect from every Frost Fire service. We use professional-grade materials — mastic sealant, metal-backed tape, and properly insulated duct — not the cheap solutions that fail within a few years.
Some rooms too hot while others are too cold? Leaking ducts, disconnected runs, or poor duct design cause uneven air distribution throughout your home.
If your energy bills are unusually high despite a working HVAC system, duct leaks are likely wasting 20-30% of your conditioned air into unconditioned spaces.
Poor airflow from certain vents often indicates crushed, kinked, or disconnected flex duct, undersized runs, or excessive duct length and turns.
Leaky ducts in attics and crawl spaces pull in dust, insulation fibers, and allergens, distributing them throughout your living spaces every time the system runs.
Rattling, popping, or whistling sounds from your ductwork can indicate loose connections, undersized ducts, or sheet metal expansion and contraction issues.
Mold growth inside ducts, moisture intrusion from leaks, or contamination from pest activity can cause persistent odors circulating through your home.
We inspect accessible ductwork for leaks, damage, insulation condition, and proper sizing. We can also perform duct leakage testing to quantify air loss.
Based on our findings, we recommend the most cost-effective approach — sealing, repair, partial replacement, or full duct system installation.
We use commercial-grade mastic sealant, properly insulated duct, and secure connections. No duct tape shortcuts — we do it right the first time.
After completion, we test airflow at each register, verify static pressure, and ensure even temperature distribution throughout your home.
Ductwork costs vary significantly based on the scope of work. Simple duct sealing for a typical home ranges from $300-$800. Replacing a damaged section of flex duct usually costs $200-$500 per run. A complete duct system replacement for a standard 3-bedroom home typically ranges from $3,000-$7,000, depending on accessibility
