Sheet Metal Fabrication in Tyler, TX

Standard pre-made ductwork comes in fixed sizes and configurations that are designed to fit common applications. Custom-fabricated ductwork, on the other hand, is designed and built specifically for your home or building. At 903 HVAC, we measure your space, evaluate your HVAC system requirements, and fabricate components that fit precisely - eliminating the gaps, mismatches, and compromises that come with trying to make standard parts work in non-standard situations.

Turnaround time depends on the scope of the project. A single custom transition piece or fitting can often be fabricated and installed within a day or two. A complete duct system for a new installation or major renovation typically takes several days from measurement through installation. Because we handle fabrication in-house at 903 HVAC, we can control the timeline more effectively than contractors who outsource their sheet metal work.

Those sounds are typically caused by thermal expansion and contraction - when your HVAC system cycles on and off, the temperature change causes the sheet metal to expand and contract, producing popping or banging sounds. This is more common with undersized or improperly supported ductwork. Custom fabrication with proper gauge material, adequate support, and correct sizing can significantly reduce or eliminate these noises.

Absolutely - this is one of our specialties. Many older homes in Tyler and the surrounding East Texas communities have ductwork that does not match modern standard sizes. Our team measures the existing openings and fabricates custom transitions, adapters, and replacement sections that integrate perfectly with what is already in place. With 40+ years of experience in this area, we have worked with virtually every type of non-standard ductwork you might encounter.

For most residential ductwork, we use 26-gauge galvanized steel, which provides the right balance of durability, weight, and workability for home HVAC applications. For plenums, equipment connections, and areas that require extra rigidity, we step up to 24-gauge. Commercial and high-pressure applications may call for 22-gauge or heavier material. Our team selects the appropriate gauge based on your specific project requirements.

Custom fabrication does involve additional labor compared to simply installing pre-made components. However, the investment typically pays for itself through better system performance, improved energy efficiency, reduced air leakage, and fewer comfort problems. When pre-made parts do not fit properly - which is common in many East Texas homes - the resulting air leaks and inefficiencies cost you money every month in higher energy bills. We also offer flexible financing through Synchrony Financial to help manage the cost of larger fabrication projects.

Yes, we provide sheet metal fabrication for light commercial HVAC applications, including rooftop unit (RTU) installations and modifications. Commercial projects often require heavier gauge materials, larger duct sizes, and more complex configurations. Our 40+ years of experience includes both residential and commercial fabrication work.

Definitely. Leaky or poorly sealed ductwork can pull dust, insulation fibers, pollen, and other contaminants from attics and crawl spaces into your conditioned air stream. Properly fabricated and sealed ductwork helps maintain cleaner indoor air. For additional protection, consider our indoor air quality solutions, including Active Gold by DustFree air filtration systems, UV lights, and humidity control.

Some signs that indicate significant ductwork problems include rooms that are consistently too hot or too cold, excessive dust in the home, high energy bills, visible damage or disconnections in accessible duct sections, and musty odors coming from the vents. Our technicians can perform a thorough evaluation of your existing ductwork and recommend whether targeted repairs, partial replacement, or a complete new duct system is the best approach.
