Ductwork Repair and Replacement in San Antonio
Schedule Ductwork Service in San Antonio
Your HVAC system can only perform as well as the ductwork it’s connected to. Weak airflow, hot and cold rooms, dusty air, and high energy bills often come from duct restrictions or leakage — not from the air conditioner itself. At Texas Air Conditioning & Heating LLC, we specialize in advanced duct repair, duct replacement, airflow balancing, and engineered duct layouts for residential and commercial properties across San Antonio, Stone Oak, Alamo Heights, Helotes, Shavano Park, Castle Hills, Boerne, Alamo Ranch, Timberwood Park, Fair Oaks Ranch, Hollywood Park, Garden Ridge, Leon Springs, and more.
We use professional-grade materials such as R-8 insulated flex, sheet metal ductwork, and 2-inch ductboard plenums and trunks for remodels, custom home builds, older homes, and commercial installations. We also offer 0% interest financing for approved credit, making upgrades more accessible and affordable.
Professional Duct Repair & Replacement Services
Most comfort problems start in the attic — not the AC unit. Our technicians inspect every duct run for damage, air leaks, poor design, crushed flex, airflow blockages, or undersized returns that choke your system’s performance. We work on all duct types: R-8 flex, sheet metal, and ductboard, ensuring your system meets airflow standards.
Common Duct Problems We Repair
- Weak airflow at supply vents
- Hot and cold rooms
- Torn, crushed, or kinked R-8 flex duct
- Leaking or unsealed metal joints
- Undersized return ductwork
- Poorly designed offsets or tight 90° bends
- Air leakage into the attic
When Replacement Is the Better Option
If your duct system is outdated, poorly routed, leaking heavily, or restricting airflow, replacing the runs with properly sized R-8 flex, sheet metal, or ductboard improves comfort, reduces energy costs, and helps your HVAC system operate correctly.
