Also Operating as “Building Scientists”

Since we opened our doors, we’ve grown far beyond HVAC. Today, we train not only HVAC professionals, but also electricians, energy auditors, plumbers, and weatherization technicians.

Over time, it became clear that “HVAC” didn’t fully convey the scope of our work or our true mission. So we created “The Building Scientists” to use when we want to put extra emphasis on our commitment to providing both HVAC and building science training. It’s one organization, one team, and the same high-level training services.

Get Your Team Certified and Qualified for Energy Rebate Programs

Serving contractors in MI, WI, NC, MN, ME, and beyond

States across the country are unlocking Home Energy Rebate dollars. But to access that revenue, your team needs to be a program-qualifying contractor, which means your team needs to be certified. Most programs require the same three BPI credentials: Building Science Principles (BSP), Building Analyst Technician (BA-T), and Building Analyst Professional (BA-P).

HVAC U offers all three. Our flexible scheduling, high pass rates, and expert instruction mean you can get your team qualified and program-approved fast, without pulling them off the job for weeks at a time.
