A Legacy of Service Since 1947

The story of Sure-Fire began with founder Emil Malesevich, who saw a need for quality heating service outside the big cities. Starting in a small Mayville shop, the company grew by always putting customer service first.

Over the decades, they expanded, adding electrical services, acquiring Behm Heating in Beaver Dam, and opening a Waupun location. In 1983, they consolidated operations into their current 18,000-square-foot headquarters in Horicon, WI. Today, they are Dodge County's largest heating and air conditioning contractor, still family-run and dedicated to the mission Emil started.
