Building value in air – from the beginning.

Greenheck began in 1947 as a small sheet metal shop located in Schofield, Wisconsin. Founders, Bob and Bernie Greenheck promoted a business philosophy based upon two concepts— continuous improvement and the determination to be the easiest company to do business with.  We applied these concepts to become a global leader in the air movement, control and conditioning industry. Our current motto “Building value in air,” reflects that philosophy. The philosophy is our commitment to our customers and remains the primary influence behind our mission and success.

Greenheck started Greenheck India Private Limited in 2013. This is a wholly owned subsidiary located in Bawal, India. The purpose for this subsidiary is to enhance our ability to manufacture and supply product for a growing customer base in India, the Middle East and Asia.

Investing in Itself

Greenheck’s continued success is due to ongoing investments in our operations and employees. Major investment in expansion and new facilities allow us to serve customers better. Manufacturing space has steadily increased, adding thousands of square feet of capacity in Schofield, other U.S. locations and in other countries. This growth is in response to ever-increasing demand for products that move air in, out, and through buildings. Greenheck also makes significant investments to attract, develop and retain employees. Leadership and career development, training opportunities, special events and wellness programs are reasons Greenheck employees rank among the best.

Leading in Innovation

There is a reason Greenheck is an industry leader. It’s because of our commitment to provide solutions to new industry challenges. Making ventilation and related equipment more energy-efficient, quieter, easier to install and maintain, and capable of the highest performance standards makes Greenheck the manufacturer others look to for the latest advances and ideas.

Robert C. Greenheck Innovation Center

Greenheck’s own development and testing facilities at its U.S. headquarters are acknowledged as the industry’s best. Here, new designs are explored, placed through comprehensive and demanding evaluation procedures and rated for specific performance requirements.

Our dedication and commitment to creating and building innovative solutions is constant and evolving. We opened the doors of a new 72,000 square foot state-of-the-art research and testing facility named the Robert C. Greenheck Innovation Center in late 2015. The facility uses sound, airflow measurement and psychrometric labs, product prototyping, and dedicated space to develop and fine-tune manufacturing processes. It also includes office space to support our technical employee growth and foster an environment for collaboration and innovation.

Manufacturing Leadership

Greenheck always looks for ways to improve and innovate across the company. An important factor in this success is improvement in operational efficiencies. Our corporate strategy to achieve Operational Excellence influences these improvements.

Year-over-year productivity improvement has enabled Greenheck to offset the impact of increasing costs and still provide competitively priced products to our customers. This in turn has allowed the business to grow and to capture increased market share.

Great strides have been made toward our Vision of Operational Excellence through:

  • Sustaining our continuous improvement initiative, the Greenheck Performance System (GPS). 
  • Investing capital aggressively back into the business providing state-of-the-art manufacturing technology and tooling.
  • Partnering with suppliers to optimize value throughout the entire supply chain.

Through these strategies, Greenheck is blending best manufacturing practices to create flexible, low-cost processes that provide unmatched value to our customers. Greenheck's Vision of Operational Excellence consists of a well-trained workforce, easily visualized systems and cost-effective equipment focused on value-added operations.

Value Engineering - Assuring Suppliers’ Processes Deliver Maximum Value

Reducing cost is important. Greenheck constantly searches for savings through internal and external value engineering, or securing cost reductions. We partner with our suppliers to ensure components purchased and installed in their products deliver optimal value for our customers.
We have applied many significant process improvements over the past few years. At Greenheck, continuous improvement is a journey, not a destination.

Greenheck Performance System - A Continuous Improvement Initiative

In May 2002, the Greenheck Performance System (GPS) was launched. Through this initiative, employees have been educated and have implemented the proven methodologies of Design for Excellence, Maintenance Excellence, and Lean Manufacturing throughout the entire organization. Each of these methodologies directly correlates to the manufacturing processes employed.

For example, through Design for Excellence Strategies, Greenheck challenges itself to deliver maximum value to customers through our product designs. This product design strategy uses cross-functional teams to exploit manufacturing processes and creativity. Our Maintenance Excellence Strategy strives for optimal equipment repeatability and availability. The equipment employed must be dependable and capable, especially as inventories are reduced and move closer to just-in-time production with single-piece flow. Through Lean strategies, we focus on maximizing the value in each value stream eliminating waste and non-value added activities.
