FriedrichAir, CCF08B10A, Chill Premier 8K, Fixed Chassis

After extensive research, I purchased a 8k Friedrich window air condition in April. I wanted a quiet air condition with a sleep mode. I could not try out the air conditioner until June, so the return period from the seller had passed. The unit is defective and makes a very loud rattling sound. I installed properly, and even moved it to another room and the rattling sound is clearly coming from the unit. In addition, in sleep mode, there is a bright blue LED that lights up the entire bedroom. The unit is useless. I called Friedrich, and they told they need a diagnosis report from an authorized HVAC contractor since they do NOT have any service people in my area. First, that is odd because I live in Boston MA. Really? No service people in a major city? They told me I have to find and pay for the HVAC person and refused to stand behind their defective product.
