Why we started ASI Mechanical

Welcome to Anderson Shaw industries, where we keep it real, keep it simple, and keep it local. We're not some corporation. We're your neighbors, friends, family - born from Tucson grit, built on trust, and powered by common sense. 

After 30+ years in the trenches of big corporate mechanical contracting, we’ve seen it all—the politics, the power plays, the ego-driven decision-making, and the endless layers of red tape. We worked under wannabe bosses more focused on control than craftsmanship and teamwork, and watched common sense get buried under spreadsheets and boardroom nonsense.

We learned the hard way. And that’s exactly why we started      

ASI Mechanical 

We’re taking it back to the basics—where grit, honesty, and good old-fashioned work ethic still mean something. No investors. No middle managers. No corporate fluff. Just real people doing real work for the community we love.

• No Suits, No Shenanigans – We’re anti-corporate, anti-monopoly, and anti-BS.
• Hands-On, Not Hands-Off – Every job is self-performed by our skilled local team.
• Simple Logic, Solid Work – We believe in doing things right the first time.
• Real People, Real Values – Honesty, compassion, and gratitude are in our DNA.
• Community First – We’re committed to Tucson, its people, and its future.

Mechanical contracting with a twist—HVAC, plumbing, and systems work done with integrity, transparency, and correctly. 

Because we’re not here to “scale” or “exit.” We’re here to serve. We’re here to stay. And we’re here for you.

To lead a quiet revolution in mechanical contracting—by rejecting corporate chaos and returning to the roots of craftsmanship, community, and common sense.

To provide Arizona with mechanical services that are honest, hands-on, and human built on decades of experience, a deep respect for the trade, and a commitment to doing things the right way.
