01  /  Who we are

A rep firm with forty lines.

EBS sells and services commercial and industrial HVAC equipment for the contractors, engineers and facility owners who install, own and maintain those buildings across North and South Dakota. The same forty-line card covers replacement and new equipment.

EBS offers complete HVAC sales and services. We focus on commercial and industrial “Use and Occupancies”. EBS runs the manufacturers’ selection software in-house: send a duty point or a spec section and the answer comes back as a sized unit and a quote. The line card is the same on a single replacement fan coil and on a full central plant.

EBS works from the drawing set.

Air distribution

Grilles, registers, diffusers and the formed sheet metal around them — the last three feet of every system, and the part a building’s occupants see.
