Custom Ductwork
Custom Ductwork and Sheet Metal Fabrication
Quality airflow starts with properly designed and installed ductwork. Krause Heating and Cooling is one of the last union sheet metal contractor teams in the Duluth and Superior area, and we fabricate custom ductwork and fittings in-house for precise performance. Our craftsmanship ensures your heating and cooling system runs efficiently, distributes air evenly, and stands up to long-term use.

Ideal for Old Homes, Remodels, and New Installs
Custom ductwork is often the best option for:
-
Older homes with limited or outdated ducting
-
Additions, basements, and attic conversions
-
Furnaces or air handlers that require special transitions
-
Homes with uneven heat or inconsistent airflow
-
Mini-split and heat pump supplemental ducting
-
Projects where standard duct pieces simply do not fit
If your current system struggles to heat or cool certain areas, poorly sized or restrictive ductwork is often the cause.
