The guy came to my house and only greased the moving parts and had it running until he left. I called the very next day and he acted as if he couldn't remember coming to my house. Finally, after much effort he admitted to remembering the work that was done. He told me that it may (the problem) something more serious and was very reluctant in returning. I was just fed up and decided to abandon all hopes of trying to get him to return. My advice to you or anyone who deals with this guy is to go ahead and hire a company with a warranty. I lost $75 for his lousy work.
