Let Us Solve Your Ventilation Puzzle

Building a high-performance home is hard enough. You shouldn't have to become a mechanical engineer or a logistics manager just to get fresh air into it.

Most Builders and DIYers face the same three roadblocks:

  • The Layout Blind Spot: Architectural plans rarely specify optimal supply and return locations. Without a clear strategy for register placement and exterior vent clearances, you risk code violations and poor air circulation.

  • The Sourcing Headache: Wasting hours trying to piece together compatible diffusers, ducting, and units from different vendors is frustrating—and finding out they don't fit together on installation day is expensive.

  • The Performance Risk: Modern homes are built tight. A system that isn't properly balanced can lead to mold, noise issues, and poor air quality, defeating the entire purpose of your build.

The Result: At ERV Design and Supply Co., we take these headaches off your plate so you can focus on the build.

About Us

Bridging the gap between strict energy codes and real-world installation.

Our Story: ERV Design and Supply Co. was born on the job site, not in a boardroom.

With years of experience in the custom home industry, we had a front-row seat to the evolution of building science. As green energy codes became stricter and homes became tighter, we noticed a glaring gap in the market: while the building envelopes were getting better, the ventilation strategies were falling behind.

To address this, we initially started a local company focused exclusively on installing ERV and HRV systems. We spent years in the field, getting hands-on experience with the equipment, the ductwork, and the distinct challenges of installation.

From Local Experts to National Suppliers: That hands-on experience became the foundation for ERV Design and Supply Co.

We realized that the headaches we were solving locally—confusing designs, fragmented supply chains, and installation errors—were happening to builders and homeowners all over the country.

We founded ERV Design and Supply Co. to take the lessons we learned in the field and make them accessible to everyone. Whether you are in Maine or Montana, we can now deliver our expert designs and custom kits directly to your doorstep.
