Gas Furnace Repair in Livonia, MI 48152

“John was extremely professional, competent, knowledgeable, conversational and fun. He immediately diagnosed and fixed the problem, checked out the entire furnace, showed me what to do for homeowner’s maintenance, and replaced the large filter. It was a pleasure to work with him (actually to watch him work). I must commend Harriman on the rapid response time. – essentially about 24 hours from call the completed repair.”
