Alternative Energy Systems LLC

Alternative Energy Systems LLC serves Royalton and surrounding central Minnesota communities with heating and cooling solutions. The company holds a 4.5-star rating across 26 customer reviews and operates Monday through Friday from 8 AM to 4 PM. Established in 2005, the business began focused on biomass boilers and has since expanded to offer heat pumps, furnaces, air conditioning, and specialized corn and wood-fired stoves. Their service area encompasses rural settings where natural gas infrastructure is unavailable, including cabins, farm properties, and outbuildings.

What distinguishes this contractor is their dual focus on traditional HVAC systems alongside biomass heating technology. They install and service Crown Royal outdoor wood boilers and St. Croix corn stoves alongside conventional gas, oil, and electric equipment. The team provides 24-hour emergency service, new system design, and full installation capabilities. This combination positions them uniquely for properties seeking alternative heating sources or off-grid solutions that most conventional HVAC companies do not offer.

Customer reviews highlight Mike and Adam responding to emergency heating failures during extreme cold weather. One reviewer described the team arriving the same day after a furnace failure, helping evaluate heat pump options for propane cost savings, and completing Saturday installations. Another customer noted the technicians thoroughly explaining system operation and answering questions even after initial installation. These scenarios reflect the company's emphasis on customer education and responsive service for heating emergencies.
