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

“I am giving my high efficiency furnace/AC unit a 12 rating on a scale of 1-10! My heat bills are only $80 in the coldest winter months. It can’t get much better than that! I am a very satisfied customer.” Audrey Pochert, St. Clair Shores MI
