Jensens Plumbing & Heating Inc was founded by Forrest “Rusty” Jensen in 1942 as a plumbing and “Hydronic” heating contractor. They serviced both commercial and residential customers back then using the latest technology of the time. Now 70 years and 3 generations later, Jensens Plumbing & Heating Inc has grown from that 1-truck, 2-employee company to one of the largest plumbing and heating companies in McHenry County with over 40 trucks and 50 employees. Our union-trained technicians can handle any heating, air conditioning, or plumbing-related installation, service, or repair. They install and service every size and type of heating and air conditioning units and ductwork from the smallest eco-friendly residential system to the largest commercial rooftop units.
