Customer Testimonials

“We are very happy with our geothermal system recently installed in the fall of 2008. It saved us money this winter in comparison to our old fuel oil system. Ron Mausolf, Les Booms and the rest of the crew were great to deal with.” Joann Sengstock, Port Hope MI

“We needed a heating solution for our old, unique home and decided to put in a geothermal system from Thumb Cooling and Heating. They were not only professional as businessmen but personable and meticulous. They did a great job and we would recommend them to anyone.” Fred and Mary Ann Jahn, Port Hope MI
