Frequently Asked Questions
How much does duct repair cost in Texas?
Minor duct repairs like reconnecting or sealing a few joints cost $150 to $500. Sealing the entire duct system runs $300 to $800. Replacing individual damaged sections costs $150 to $400 per run. Complete duct system replacement ranges from $3,000 to $7,000 depending on home size. A duct assessment with pressure testing costs $100 to $250 and identifies exactly what repairs are needed.
How do I know if my ducts need repair?
Common signs include rooms that are significantly warmer or cooler than others, high energy bills despite a functioning AC, excessive dust coming from vents, whistling or rattling noises from the duct system, and visible damage such as sagging, disconnected, or torn duct sections in the attic. If your AC system is working hard but your home is not cooling evenly, duct problems are often the cause.
Why are duct leaks such a big problem in Texas?
Texas attics regularly exceed 140 degrees in summer. When cooled air leaks from ducts into this superheated space, it is completely wasted. Studies show the average Texas home loses 20 to 30 percent of conditioned air through duct leaks. This forces your AC to run significantly longer, increasing electricity costs by $30 to $80 per month during peak summer. Sealing duct leaks is one of the highest-return energy improvements available.
What is Aeroseal duct sealing?
Aeroseal is a patented technology that seals ducts from the inside. The process involves pressurizing your duct system and injecting aerosolized sealant particles that collect at leak points and seal them. It can reduce duct leakage by up to 90 percent and reaches leaks in areas that are inaccessible for manual sealing, such as inside walls or under insulation. The process takes 4 to 6 hours and provides computer-verified results.
Can I seal duct leaks with tape or mastic myself?
You can apply mastic sealant or metal-backed tape to accessible duct joints in your attic as a temporary fix. Never use standard cloth duct tape, which fails within months in hot attics. However, many leaks occur at connections hidden under insulation or in wall cavities where DIY access is limited. Professional duct sealing covers the entire system and includes pressure testing to verify results.
How long do repaired ducts last?
Properly repaired ducts with mastic sealant and quality connections last 15 to 20 years. Aeroseal treatments have a proven track record of 10 to 15 years based on long-term studies. New flex duct installed with proper support straps and sealed connections in a Texas attic lasts 15 to 25 years. The key to longevity is proper insulation to protect duct materials from extreme attic heat and UV degradation.
