Doc, We have a horizontal closed loop geo system and are located in Ann Arbor Michigan. I have been following conversations on the forum for a few years and I respect how you interact with other members and the way you advise. I would like advice on maintenance on our system and any improvements for efficiency. I am wondering if you have a recommendation of someone to contact in our area. Thank you, Doug
