I want to tell you what an awesome program BuildATech® is. My nineteen-year-old son went through it last March and he’s performing like a star.

As an AC novice, I came into this class with only the most basic understanding of how an air conditioner works. Working with the team at Lennox, I now feel confident and proficient as an HVAC professional.

Learning the how/why of the system was a big help. Knowing the science and processes involved make understanding set up and troubleshooting much easier.
