Three years ago, I replaced my mother's aging a/c system with an amana brand hvac, inside and outside unit. It's been a problem ever since, with component failures. My mother is 91 years old, and the reason we replaced it was to give her piece of mind. She's had everything but. I can provide the service history and the local installer info if needed. My mother used the word "lemon" to describe it yesterday. She's right.
