Reliable Experience: We Know Furnaces in Slave Lake!

Marten Mountain Metal Works is a locally owned independent Lennox® dealer here in Slave Lake carrying furnaces, air conditioners, and more. We have been serving Slave Lake and the surrounding communities for over 40 years. The goal at MMMW is simple: great service. We want to supply you, the consumer, with a level of customer service that cannot be beat along with a quality product you can trust for years to come.

Benefits of Our Planned Service

Having a certified HVAC technician inspect your furnace helps the longevity and performance of your equipment. Our technicians complete a detailed list of tasks while on site.

We make sure that your furnace is clean and that all the components are checked for preventative maintenance.

Avoid Feeling the Chill

Albertans can’t afford for their furnace to break down in the middle of winter. Unfortunately, it can and usually does during Alberta’s coldest months as your furnace is under a lot of load.

MMMW and the manufacturers we service recommend having your furnace checked in the fall for its continued upkeep. Call us for installations, renovations, repairs, and upgrades to keep your property warm when you need it most.


We provide cost-effective solutions to help maintain the function or your HVAC equipment.
