HVAC & plumbing representatives in Michigan.

Zach Ziroll leads SEI’s Michigan work as Sales Director — Michigan. His background at Robertson Heating Supply and Johnstone Supply spans warehouse and counter operations, territory sales and branch management.

At Robertson, Zach led the new Brighton, Michigan branch. That experience gives him a practical understanding of what branch teams need to stock, explain and support a product line.

Current field activity includes metro Detroit, Grand Rapids and Lansing. Zach’s application experience includes communicating and zoned HVAC systems, radiant heating, press connections and alternatives to brazing. He works with distributor teams and contractors on product education and also covers Indiana.

Michigan coverage is part of SEI’s seven-state agency. The separate six-state HVAC equipment growth figure does not include Michigan; we keep those two scopes distinct.

Representation that fits your line.

SEI represents HVAC equipment, plumbing products and professional tools across seven Upper Midwest states. Coverage for a particular manufacturer depends on the product, existing arrangements and the markets agreed with that manufacturer.
