Working with a Legend

Jim Sinclair, aka Jimmy Diffuser, is a legend in HVAC. These are not just my words, I hear it everywhere I go with Jim.

He started in 1975 and carved a niche in HVAC with expertise in thermal comfort and treating people right.

I have been learning from Jim from afar for 9 years and recently in person as we transition the company he founded in 1985.

Our factory trips this week confirmed his legend status as many people went out of their way to say “thanks”!

We continue to work together as he remains Chairman of the Board, giving guidance on thermal comfort and more.
