Discovered that the attic access hatch isn’t insulated, which honestly isn’t surprising given when it was built. No ladder system. I’m working on cutting up some foam boards to glue to the backside. Hopefully it will reduce how much is radiated through this barrier.

We recently found out that one of our ducts was just petrified old tape, there had never been any metal ducting there at all. It wasn’t cheap to get fixed but it has made a noticeable difference in how long the AC is on and the temp in the house.
