D&K Generators, Boilers, and Geothermal

We’ve served Morrison and surrounding communities as a trusted generator and heating specialist since 1985. From our location on Highway 78, two and a half miles south of Morrison, we serve customers in Prophetstown, Sterling, Dixon, Rock Falls, Fulton, Savanna, and nearby areas. We are licensed, bonded, and insured, and we are affiliated with NFIB and the Chamber of Commerce.

Our services include the sales, installation, maintenance, and repair of generators, boilers, geothermal systems, and air-to-water heat pumps. For generator customers, we help select and install systems for homes and commercial properties, then provide the ongoing maintenance and repairs needed to keep them ready. Our technicians service all major generator brands. We also sell, install, and service boilers, helping customers choose equipment suited to their space and heating needs.

We design, install, and maintain geothermal systems that use the earth’s natural energy for efficient year-round heating and cooling. We also specialize in air-to-water heat pumps, which transfer energy from the air into water-based systems for radiant floors, radiators, or domestic hot water. Whether we’re completing a new installation, performing routine maintenance, or diagnosing a problem, we focus on knowledgeable service and dependable, long-lasting comfort solutions. Customers can find us at 12503 Crosby Road in Morrison or reach us at (815) 772-4404.
