Our Story

When Bill and Nancy Simpson met nearly 40 years ago, their marriage wasn’t the only perfect union formed: Bill’s HVAC industry expertise and Nancy’s 15 years of business experience came together beautifully to create Simpson Sheet Metal as we know it.

Since then, our team of 6 has grown into nearly 60. Our simple household HVAC services have expanded to include heating, cooling, ventilation, and custom sheet metal fabrication for commercial and residential buildings alike.

Through all this, one thing has remained: our commitment to our community.

Sadly, Simpson Sheet Metal lost Bill in 2009, but his legacy persists. The family business continues on, not only through Bill’s children and grandchildren but also through each and every dedicated employee who has made this into more than just a business.

We value family, friendship, and community—we value you.
