50 Emergency HVAC Contractors in Duluth, MN

Duluth sits at the western tip of Lake Superior, creating one of the most demanding heating climates in the continental United States.

Fifty-one contractors serve this metro area, maintaining an average rating of 4.1 across nearly 4,780 customer reviews.

Service call pricing reflects the complexity of after-hours work. An after-hours service call on a weekday evening runs $165-$330, while a weekend service call typically costs $193-$358. Holiday calls, including major holidays, can reach $248-$495. Minnesota requires that HVAC contractors hold a license from the state Department of Labor and Industry, which means they must employ a licensed Master HVAC professional to perform heating system work legally.
