Krause Heating & Cooling
Krause Heating & Cooling installs and repairs furnaces, heat pumps, ductless mini-splits and air conditioning in Duluth, Superior and nearby communities.
What they do
Furnaces, heat pumps, ductless mini-splits and air conditioning make up the core of the work, with heating repair alongside. Custom ductwork and fittings are fabricated in-house, aimed at better airflow. Technicians are union-trained, and the family-owned firm has operated since 1982. Mini-splits suit older homes, cabins, additions and homes without ductwork, while heat pumps can be paired with a furnace in a hybrid system. The company focuses on residential service but takes on select light commercial work. Estimates can be requested online. Service calls reach up to about 50 minutes from Duluth, covering communities in Minnesota and Wisconsin. Financing is available.
