Service by trusted experts

Your boiler plays a central role in your hot water heating system so you need a company with journeyman plumbers and mechanics that specialize in working with them.

Historic homes are our specialty

The original gravity hot water or steam heating systems still operating in many historic homes require true craftsmen to maintain and service them.

Years of wisdom

Our wisdom of these systems has accumulated over years of diagnosing and servicing equipment in homes built from the late 19th into the early 20th centuries.

We fix what others can't.

Our high level of familiarity and understanding of how these old-fashioned systems work is the key to our success.

Experts in steam systems

More art than science, the correct replacement and repair of a steam boiler is a rare skill.

Luckily, the mechanics at Carlson Mechanical have the necessary knowledge to ensure a properly functioning steam-heat system.

Designing new and modern steam boiler systems with our signature installation process is a Carlson Mechanical specialty.

We've got you covered.

Your boiler plays a central role in your hot water heating system which makes it one of the hardest working pieces of equipment in your home.

Install & replace

You need a boiler that delivers consistent service and we only install boilers from trusted, leading manufacturers such as Lochinvar, Burnham, and Viessmann.

All makes & models

Our skilled mechanics keep our trucks well stocked, which means we can usually fix your boiler on the first trip. Please note that we do not work on forced air systems.

Annual maintenance

Annual service will prevent unwanted breakdowns by catching small problems before they turn into expensive fixes.

Our clients say it best...

“A big shout out to technician Dennis, he was thorough, knowledgeable, and all around excellent servicing our gas boiler furnace this month. We will be a customer for life with Carlson Mechanical from here on out!!!”

Jerry G.Seattle

“We didn't even know Mark had done the original install of the boiler at the house we bought until we went to sell it and our buyers wanted it serviced.

Mark came through and helped us in a bind! Professional, timely, and went above and beyond what he needed to do to help us out. I'd use Carlson Mechanical again in a heartbeat!”

Becca L.Edmonds

“From Amy in the office to Dennis the boiler tech, I'm thoroughly impressed with Carlson, and I'm picky. Not only did he work swiftly to troubleshoot why my boiler would not stay running, but explained each step of his findings as he worked.”
