At year 7 after purchasing my new A/C system from Clean Air, the blower fan in the air handler burnt out. When Clean Air's tech came to my home on 8/2/2017 all of the information about the warranty came to light. However, Clean Air did not take accountability for the fact that the part should/would be covered under a 10 year warranty if they properly did their job at the time of installation. In the tech's presence, I placed a call directly to Carrier, who confirmed that the part would be covered by a 10 year warranty, except for the fact that the warranty was not registered by the installer (Clean Air). The tech discussed these issues with his Service Manager, who took no accountability and seemed to be too scared to speak to me directly, relaying all information through the low-level tech.
