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.


The "EP" in EP Sales stands for Eddy and Ponschok — a friendship and partnership that began on the football fields of Lawrence University.
At EP Sales, customer service is our foundation.
Contractors can reach a live person, any day, any time (except holidays and during the occasional Packer/Viking rivalry game!)
We do what we say — a principle not always common in the rep industry.
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.
— Dave Ponschok
Our greatest achievement is the positive feedback we continually receive from contractors at trade shows and in the field.
— Bob Eddy
We are passionate about growing while holding true to the values that have fueled our success since day one.’
