It is unfortunate I have to write this but my experience with Mr. Clint Cluff has become nothing short of a nightmare! Current customers I have a question for you; were you asked to register your unit or did the company do it? Also Mr. Cluff spoke to me in a condescending manner. I felt very violated as I paid for a service and have a warrenty that he has declined to honor. I am unsure if he expects me to not fight this because he was speaking to a woman or due to my Hispanic name. I will never recommend Cluff Mechanical and current customers seek validation to your warranty!!! I can show you my warranty.
