A NEW CHAPTER
Ron Coleman Retires, Brian Merritt Named President
In September 2026, founder Ron Coleman retired after 46 years of leading All Temp Mechanical. Ron built this company on hands-on boiler know-how and a commitment to doing the job right, and that foundation isn't going anywhere.
Brian Merritt is stepping in as President. With more than 20 years in the mechanical industry, Brian brings a fresh attitude and a real desire to grow relationships with our clients, while keeping the same high standard All Temp has always been known for. Same team, same service, same phone number.
THE FOUNDER
Ron Coleman
With his expert technical knowledge and years of diverse experience, Ron Coleman is widely regarded as one of the industry's most trusted advisors and specialists. Growing up on the historic steam ship, the S.S. Virginia V, Ron had the opportunity early on to get first-hand experience with boiler systems and has had a passion for the industry ever since. Quickly developing a reputation for his strong work ethic and adept skill set, Ron continued to advance in his field by founding All Temp Mechanical in 1980. The success of the business became a natural by-product of his uncommon experience, dedication and client-focused approach. To this day, All Temp Mechanical remains as one of Seattle's top commercial boiler contractors.
THE PRESIDENT
BRIAN MERRITT
With more than 20 years in the mechanical industry, Brian is a hands-on leader who believes great service starts with a great team. He takes pride in building a crew of skilled technicians who truly love what they do, and he knows that when his team is supported, respected and set up to succeed, it shows in every boiler room they walk into. Brian leads by example, sets a high bar and backs his people, and he brings that same energy to building strong, lasting relationships with the property managers and building owners we serve. Under Brian's leadership, All Temp keeps the high standards Ron built the company on, with a team that's proud to be here. Away from work, Brian is a proud dad of four and is married to his amazing wife, Allison who works in the finance industry. Under Brian’s leadership, All Temp Mechanical remains one of Seattle’s top commercial boiler contractors, with its best years still ahead
