Mike and his team installed 3 Mitsubishi ductless systems in our downstairs bedrooms and hallway. We needed them mostly for heating to replace our under floor hot water system. They have been excellent ! performing great in even the coldest of Chicago winter nights! The bedrooms and hallway has been kept warm and cozy, great performance. Most of all Mike and his teams service was outstanding. They installed the system in 3 days with high quality and professional work. Mike stayed in touch with us afterwards to make sure all worked well and ongoing support. I would highly recommend the system and most of all Mike and his team to do the job. Thank you Mike, great work!
