Your Experienced Heating and Cooling Professionals

Marten Mountain Metal Works is a locally owned and operated company serving the heating and cooling needs of northern Alberta homeowners, contractors, developers, and business owners. 2014 marked our 40th anniversary in business, and we’ve been operating in the Slave Lake area throughout this time. Over the years we have gone through a lot of changes, but one thing that has never changed is the quality of our work. We take pride in being part of this community and look forward to spending at least another 40 years helping the people of the Slave Lake Area.

MMMW was created by Larry Bumhagen in 1974. Larry saw an opportunity to create a business in which he could build a future for his family. Larry had a dream that his son, Richard, would one day take over the company. Richard did just that in 2006 and still runs the company on the same values his father has instilled for the last 40 years.
