Built on Island Values.
Built to Last.
Southern Maine Mechanical was built from the ground up by a guy who grew up hauling traps before sunrise on Chebeague Island. The work ethic hasn't changed — only what he's fixing.
The Story
From the Lobster Boat to the Boiler Room
James Kuntz grew up on Chebeague Island — a tight-knit fishing community in Casco Bay where long hours, resilience, and pride in your work aren't values you're taught in a classroom. They're just how things are done. His family lobstered for a living, and from an early age James learned what it meant to show up when the weather was bad, to fix things yourself when you couldn't afford not to, and to earn people's trust through action, not words.
That upbringing — hauling traps at 4am, maintaining gear, solving problems with whatever you had on hand — became the DNA of Southern Maine Mechanical. James built the company from nothing, combining the blue-collar work ethic of his island roots with modern HVAC and plumbing expertise built through years of hands-on field work.
He's known for taking on challenging projects — the ones other contractors decline — and for treating customers the way people on a small island treat each other: fairly, honestly, and with the expectation that your reputation follows you everywhere you go.

"On the island, if you said you were going to show up, you showed up. If you said you'd fix it, you fixed it. That's the only way I know how to run a business."
What We Stand For
Island Values. Modern Expertise.
Reliability
On Chebeague, if someone said they'd be there, they were there. We bring that same reliability to every service call — same-day response, on-time arrivals, and jobs done right the first time.
Honesty
We tell you what your system actually needs — not the most expensive option. If a $200 repair will solve your problem, that's what we recommend, even when a full replacement would be more profitable for us.
Pride in the Work
Clean installs, proper sizing, no shortcuts on materials. The kind of job where we're happy to put our name on it — because on a small island, your reputation is all you have.
