It is with great sadness that I post this thread. My friend and mentor, Jim Davis, passed away in his sleep on Saturday 6/20/2026. He was 79 years old.

I met Jim in 1993 at the class he was giving on CO and combustion. I can honestly say that his class changed me as a contractor. In my many years in this industry, I have never met a man more dedicated to educating people and more importantly, saving lives.

I know as a fact that many contractors that use this forum have been just as affected by Jim's teaching. I met Matt Sweeney at that first course in 1993, and he has never forgotten Jim or what Jim taught him. Jim also held Bob Harper in high esteem. Jim referred to him as a genius in many of our discussions. While he and Bob did not agree on everything, they agreed on the most important things. If you don't test, you don't know.

Jim contacted me in 2023 to bring me on board at NCI as an instructor. What an absolute blessing it was to get to work with my mentor and learn from him before his passing. While he is no longer with us, his legacy will continue.

Very sad to hear this. I loved reading what Jim had to say. I always meant to get down there to take one of his classes. He was truly an unsung hero of our industry.

I am heartbroken 💔. I loved this man. Jim was "A Disruptor" (Be a Disruptor by Stratis Morfogen). Jim had nerves of steel and feared no man or beast. Saw Combat in The 'Nam. Jim cut right through the Bull and gave it to you straight. He was also one of the most brilliant men I ever have encountered in this business.

I still remember hosting Jim at my Mom's House in Floral Park for Steaks and some Fine Kentucky Bourbon after his training class down here on The Island 🏝. We even did a Field Trip to My House with the Class to test my new Boilers. My Brother Bart and Mom Colleen (Both Gone) hosted Jim, Mark Hunt and Darin Cook, Johnny New York Cataneo and a few others.

Thank you for letting us know, Mark, and please post any pertinent information here. Mad Dog

Combustion analyzers back then were smaller than some of todays models. Jim probably would have given someone a concussion with the new ones. Al is very much alive and still with NCI. He had a close call with a heart attack a couple years ago, but he's doing very well.

This sucks, Matt. We had a great group of all-in dedicated guys back then and we all learned from each other. The guys you mentioned, Darren, Mark Hunt, etc I haven’t spoken to in many years but my goodness the yelling and screaming we did back then, all in great fun. We socialized with Jim Davis and he scared the crap out of us some days. I became a good CO tech (testing, detecting, and eradicating) because of what he taught us. I know, I know: He would go head to head with the manufacturers but he could always back up his **** with test results.
Rest in Peace, Jim Davis.

We'll never see his like again. Mad Dog

I'm sorry to hear of his passing. You always learned something new from whatever he posted.
