Boilersource is now a Certified Women-owned Business Enterprise in both Illinois and Indiana!

We are pleased to announce that Boilersource has received our Indiana WBE certification. We are now a certified WBE and DBE in Illinois, AND a WBE in Indiana! As a regular dealer of boilers and associated equipment, we recognize the commitment to supplier diversity that is embraced by corporations and government agencies today.

Our promise to provide the highest quality boiler equipment, paired with custom and comprehensive mechanical room solutions, has set us apart for our storied 50 year history. Tricia Fredrick, President & Chief Executive Officer, has worked tirelessly to reinforce Boilersource’s legacy of providing innovative products and remarkable customer service. Her dedication to excellence extends into the company’s Total Lifecycle Commitment, or TLC360˚ promise. By reinforcing this obligation, and updating the Boilersource brand, Tricia strives to continually grow and improve on Boilersource’s mission of “Going Beyond the Boilerplate."

While WBE certification doesn’t change the premium products and services we deliver, it does help our clients meet their vendor diversity goals. Companies and government agencies that hire certified WBE businesses as their vendors show their dedication to fostering diversity. We’re happy to have you all on board as we venture into exciting and new territory for Boilersource and our devoted customers.
