Recommend MSI to everyone
My geothermal heating and cooling system was not doing it’s job. It was not too hot in August so we were able to get by without air conditioning for a few days. I called MSI and explained the problem. They had a service tech in the area and he was here within an hour. He diagnosed the problem but was not able to fix at that time. He returned two days later and fixed it. I will recommend MSI to everyone.
