Inside the Wild World of MEP Design: Site Visits, HVAC, and Engineering Oddities

On this episode of ProfitDig Live, we sit down with Phillip Greer to talk MEP design—short for Mechanical, Electrical, and Plumbing. But don’t let the technical acronym fool you—this conversation takes some hilarious turns.

Phillip has worked across the country on everything from wastewater treatment facilities to ice cream plants built in repurposed meat packing buildings. He shares stories from site visits that range from informative to downright bizarre—like walking into a freezer mid-shoot for a “spicy” video production (yes, that really happened).

These days, Phillip focuses on HVAC design, helping ensure that ventilation systems in treatment facilities meet health and safety standards. It’s not glamorous work, but it’s essential—and incredibly complex. “You’re not the most important part of the building,” he says, “but ductwork takes up a lot of space, and somebody has to figure it out.”

We also dive into how MEP designers use Revit and CAD, what it’s like to inherit decade-old municipal jobs, how dummy thermostats help keep the peace, and the challenges of working in a space where your equipment always has to make room for everything else.

From the technical to the absurd, this episode has it all.
