First, a little back-story. I've been having trouble with the air-conditioning system in my south-Texas apartment home for almost two months so far this summer. The apartment manager has been sending their "A/C Certified" (the certification a whole separate thing to be skeptical about) technicians to my apartment. On each occasion that a technician comes to my home, he wants to just glance at it and tell me there's nothing wrong in spite of my explanation. I nearly have to poke him with a stick to get him to give it more than a cursory examination even after I explain that the indoor temperature tops 80 degree Fahrenheit every day.
However, one of the technicians observed that there was an area above the living room where the insulation above the ceiling is missing (I confirmed this observation), and so the apartment manager called for an outside contractor to come service it.
He came to my apartment and told me that not only was a section of insulation missing, but that all the insulation above my apartment was old and needed to be replaced. I am very skeptical of this claim because I've never heard of such a thing, and also I never had any trouble with the temperature in the winter time. The apartment manager has not had time to act upon his recommendation AFAIK, but it sounds to me like we're being taken for a ride.
I've never heard of such a thing as building insulation needing to be replaced when it reaches a certain age. Personally, I've nearly given up hope on the situation and have begun making plans to move my family to a new home.
Therefore, my question: is building insulation a thing that wears out and must be replaced eventually in order for my apartment home to stay cool in the summertime?
