About Us

Our Story

Founded in 1998 by Dave Ponschok and Bob Eddy, EP Sales began with a mission: to meet the growing need for better ventilation solutions in the wake of changing construction practices in the 1980s.

Seeing the rise of indoor air quality (IAQ) issues due to new energy-efficient home designs, Dave and Bob introduced whole-house ventilation systems to the market. From that first air exchanger (HRV) to today’s expanded lineup of HVAC and hydronic heating products, our commitment to innovation and service has never wavered.

What Sets Us Apart

At EP Sales, customer service is our foundation.

We stand out because we:

Answer the call:

Contractors can reach a live person, any day, any time (except holidays and during the occasional Packer/Viking rivalry game!)

Deliver on promises:

We do what we say — a principle not always common in the rep industry.

Solve problems fast:​

Our team works closely with contractors to troubleshoot, identify issues, and provide immediate solution

Our customers often share their appreciation for the way we go the extra mile, providing critical parts, tech support, or simply lending a listening ear to help them get the job done.

When a contractor is frustrated because something isn’t working right, we help them fix it so they can move on — and get home to their families.

Our greatest achievement is the positive feedback we continually receive from contractors at trade shows and in the field.

Looking Ahead

Our journey is far from over. EP Sales is committed to:

We are passionate about growing while holding true to the values that have fueled our success since day one.’
