Fellow Tin Knockers:

No smoke and mirrors here. CHI Manufacturing is one of the best companies I have ever worked with. From the front office to the people on the floor, Phil has shown his people the correct way to treat their customers, always pleasant and helpful, they want to make sure you are happy with the end product. Communication and
quality are never an issue.

Probably the best sheet metal Fab I've ever worked with in my 25 years in the trade. They go above and beyond. Their ductwork is so well fabbed it makes the installers job a lot easier.

We have been a customer of C.H.I. for a number of years. We enjoy doing business with them. CHI has fair and competitive pricing. The orders are as accurate as is the invoicing and we have confidence in the scheduling of deliveries. We have no difficulty recommending CHI to others. We refer walk-in customers to C.H.I. for all prefabrication needs.

Great place where they still believe in making good products in the U.S.A.

I have worked in the Sheet Metal Air Distribution Industries in the Denver marketplace for many years and have had the pleasure of working with C.H.I. Manufacturing during this time. The products that they represent, the ductwork and fittings that they manufacture and the personnel that work within the company are second to none. They are recognized within the marketplace for their customer service.

CS Winair has done business with C.H.I. for the last six years - we use CHI for the quality and service they they provide. The staff is so helpful and great to work with. Quality and lead time is the top of the line. If you are looking for a great product and service, Phil and his staff are the ones you are looking for. Hats off to them!

I want to give a special thanks to Ryan for handling a very difficult situation on one of my projects. This project is a LEED project and requires very specific paper work on all products. Ryan tracked down all of the paper work that is required well before anyone else on this project. At this time, I plan on using C.H.I. exclusively for all my sheet metal needs.

Yelp Review:

I needed some custom ductwork done for a DIY project and found C.H.I. This is a local family business and their pricing was exremely fair when you consider you are ordering a piece of hand built custom sheet metal work. Whether you're a pro or ametuer (like me) they are certainly a business worth supporting.
