About Us

Our Story:

Air Flow is a Heating, Ventilating, and Air Conditioning (HVAC) manufacturer’s representative serving Wisconsin and the Upper Peninsula of Michigan. Founded in 1973 by Allen Gelin and Neil Drees, Air Flow has earned its reputation among its customers in the commercial, industrial, and institutional marketplace.

Air Flow has over 25 employees and operates out of a 54,000 square foot facility in Milwaukee, Wisconsin. We represent over 50 manufacturers of HVAC equipment and thousands of individual products.

Why Air Flow?

We know your customer is your priority, not us. We also know all reps look alike. We offer similar products, at similar prices, with similar services. So what makes us different? As President Tom Gelin puts it, we have a patented system of “Give-a-sh**-ology. Yep, we really do give a sh** about your project.

That means we do the little things others aren’t willing to do, so you can have a successful project, get home in time for supper, and sleep well at night.

Any company can sell you HVAC products, but only Air Flow delivers the Range, Support, and Experience you need for lasting success.
