D G Solem & Sons

D G Solem & Sons has served Duluth homeowners since the company was established over two decades ago, building a reputation on consistent, high-quality HVAC work. The family-operated contractor holds a 5.0 star rating across 13 verified reviews, a perfect score that reflects their commitment to doing the job right the first time. Operating from their Duluth headquarters, the team handles heating, cooling, and ventilation projects across the city and surrounding St. Louis County. Their standard hours run Monday through Friday from 8 AM to 4:30 PM, with emergency availability that has saved residents during holiday crises.

What distinguishes DG Solem from other regional contractors is their specialized expertise in hydronic heating systems, which use heated water to warm homes through radiant floors or baseboard radiators, a service many area companies do not offer. They also maintain in-house custom ductwork fabrication capabilities, allowing them to build ventilation solutions tailored to older Duluth homes with non-standard layouts. The company handles new construction installs and provides full-system replacements, giving homeowners a single point of contact from design through final inspection.

Multiple reviewers specifically name technician Mike and his colleague Kevin, describing their approach as exceptionally clean and efficient. One Duluth homeowner received same-day service when their furnace failed two days before Christmas, with the team completing a full replacement in just two hours without leaving a trace of their work. Another customer away during the holidays trusted DG Solem to order parts and restore heat while they were traveling, a level of responsiveness that earned the company their future maintenance business. Technician Pete has also handled propane plumbing projects, demonstrating broader mechanical capabilities beyond standard HVAC work.
