We were told by a few companies that we needed to replace our furnace. Michael came out, tested everything, found the cause of the issue (which 4 other companies could not do, they were just trying to sell us a furnace) and fixed everything. The professionalism and honesty was GREATLY appreciated. I was expecting to replace the furnace, but Michael assured us that it was not needed and explained everything in detail. HIGHLY RECOMMEND!
