Warwas Heating & Cooling

Warwas Heating & Cooling is a Duluth-based HVAC contractor maintaining a 4.7-star average across 18 client reviews. This locally-operated business specializes in furnace and central air installation for homeowners throughout the Northland region. Reviewers consistently highlight technician Corey as the primary contact, noting his combined expertise in heating, cooling, ventilation, and related trades.

What distinguishes Warwas Heating & Cooling is the owner's breadth of hands-on trade knowledge spanning plumbing, electrical, and carpentry alongside HVAC work. Multiple reviewers reference tackling complex jobs involving older homes with complicated ductwork systems that other contractors declined. Corey individually assesses each situation and applies multiple skill sets as needed rather than subcontracting unfamiliar tasks, which minimizes disruption for homeowners during major installations.

Customer scenarios from published reviews illustrate on-site problem-solving in action. One reviewer describes going without heat in parts of her house since December before Warwas restored heating, airflow, and peace of mind through patient explanation and thorough work. Another mentions Corey cleaning air ducts where competitors refused the job due to tight crawlspace access, then installing a new heater on a Saturday when their existing unit failed ahead of fall. A third reviewer appreciated that Corey worked through a holiday weekend to ensure a family stayed warm.
