Mark Huff · A life in the trades
I've spent more than 30 years around HVAC and mechanical systems, from service trucks and controls to project management and sales.
There's a lot to respect in this industry, and a lot for the next person to discover. My books and Mechanical Marauders are ways to open that conversation.
The bigger pictureExplore the books
The work behind the everyday
A comfortable building depends on work most people never see. The trades bring together practical skills, problem-solving, experience, and people willing to keep learning.
I want more people to notice that work and see the possibilities in it. That means making the industry easier to understand, giving the people doing the work some attention, and leaving room for a little dry humor.
Explore Mechanical Marauders
Mechanical Marauders is my separate side project for that bigger conversation: the people, the systems, the learning, and the ways someone might find their place in the industry.
Explore Mechanical MaraudersA view from the field
The trades bring people, equipment, planning, and practical skills together. A career in this industry gives you plenty of reasons to look beyond the part of the job right in front of you.
That broader view is part of what I want to share, alongside the books and the conversations they can start.
