Cassie and her team just left my house. They were SO friendly. They were very efficient. I was giving a window of arrival between 11:30 & 12:30. They were a few mins early and took about a half an hour to complete my furnace cleaning. They recommended a new humidifier and hot water tank (which we know soon needs to be replaced) and provided a quote. Did not feel as if I was being sold something, was information! Would absolutely use these guys again and would 100% recommend to anyone who is looking to get this done. They have great online deals!!
