EIR Testing & Maintenance Co.
In 1983, EIR Testing and Maintenance began servicing OCRs for cooperatives in the Midwest. Dennis Betz and Eric Gagne, of B & B Transformer, purchased EIR Testing and Maintenance in 2004. In 2017, Eric identified the need to provide increased customer contact and partnered with John Tonsager. EIR Testing and Maintenance has always been committed to high quality and customer-focused service. We are proud that we have technicians with over 20 years of experience with EIR Testing and Maintenance.
Today EIR Testing & Maintenance is proud to serve nearly 100 cooperatives throughout the United States. Our controlled growth through the years has allowed us to maintain our rigorous service standards and pay close attention to the details.
Tours & Seminars
We gladly welcome tours for our customers at our facility in Northfield, Minnesota. We also host OCR seminars in the spring each year to allow cooperatives an opportunity to expand their knowledge with OCR’s.
