Satisfied Mechanical Contractors



"I have been ordering duct from Superior Duct Fabrication for a decade now and they are an excellent company to work with! 

They always get me what I need when I need it! David Newcomb at the Pomona Headquarters is my go-to guy and I always feel that he is transparent and straightforward. No other company on the West Coast is capable of anything close to what Superior Duct delivers. 

"From budgeting and bidding to project completion, SDF has performed above our expectations. They have helped fill in the gaps when our own fabrication shop is overwhelmed, which allows us to continue to produce for our larger customers and General Contractors.

Our BIM detailing dept. can send full fabrication files for quote and release ensuring that all parts are built to our standards. Their lead times, quality, and deliveries are below none. Superior Duct Fab is efficient, reliable, and a pleasure to work with every time."

"I just wanted to reach out to [Taylor Mortensen, Sales Director] and let you know how much I appreciate working with Dani [Conaway, CSR]. She has been awesome at tackling some large work that was tricky to get all the logistics to come together correctly. Every time I have a special request or need, she jumps in and gets it taken care of. In a day and age when good employees are hard to find, it is good to know you have one of the great ones.

"I walked our San Manuel Casino project earlier today and it is my understanding that Superior provided 100% of the Sheet Metal Fabrication for the project. Our GF running the project indicted to us that everything that was supplied by your team was BULLETPROOF.


On top of delivering a top notch product ,  my GF told us  that the service from superior was even better.  As you’re probably aware it’s a very challenging site logistically and when our fab partner goes out of their way to make things happen for us  our productivities ,  which translates to other things , goes to another level.  We appreciate your continued effort and performance !"
