About Us

Established in 1926

CW Suter has been in Sioux City since 1926. In that time, we’ve developed a strong relationship with our community. Installing top-notch HVAC (Heating, Ventilation, and Air Conditioning) systems, providing high quality equipment for commercial, industrial, and residential clients in the area. We’re proud to say that our customers and our community know that they can count on us for fast, reliable service. Companywide, our priority is to continually earn that reputation.

Our Culture

We strive to provide excellence and professionalism in all aspects of our business. We value community, innovation, efficiency, integrity, and a willingness to adapt. We promise to provide a quality product and an exceptional experience to each of our customers, while empowering our employees to reach their personal, economic, and professional goals.

Our Objectives

Remaining sensitive to our customer’s needs, taking care of our employees with training opportunities and support, giving back to our Sioux City Community, and ensuring that we continue to provide the industry’s leading technologies and services. These four concentrations have helped us become a highly reputable company with a loyal clientele base, and we intend to keep it that way.

100% Employee Owned

As of 2023, we completed the successful transfer of 100% ownership of our company to our employees via an Employee Stock Ownership Plan (ESOP). Through our ESOP, CW Suter employees share the pride and experience of building our powerhouse business. Our ESOP is an employee retirement plan where you’re gifted an account invested in CW Suter stock (a privately-held company). We fund the plan completely — you don’t put any of your own money into it. This is a way we can share the business with all of you as employee owners.

Being employee-owned doesn’t affect the way our company operates. Everyone still plays their part in the structure of the company. It just affects the stake our employees have in the company’s success. When the company does well, you get to share in that success through the stock in the ESOP.

Commercial HVAC & Plumbing Services

Commercial customers are able to utilize our services in a number of ways. We have HVAC, Temperature Control, Sheet Metal Fabrication, and Plumbing. All are handled with the utmost care and latest technologies for the best results. In addition to the general heating and cooling services, we also provide professional BIM/VDC Coordination (Pre-Construction Services) for commercial customers.

Residential HVAC & New Construction

After almost a century in business, you can count on us to keep your home comfortable and healthy. From heating and air conditioning to indoor air quality systems, we repair and replace any manufacturer’s equipment. When replacement is the best option, we carefully analyze your needs to provide solutions that make your environment the best it can be. We will determine the products that best suit your home, needs, and budget.
