Spoke to the install guy and told him we can't get room temp less than 5F below outside air temp. This seems unacceptable, but he says it's not and his AC evap froze up yesterday at his house do to the high dews/temp. It was only 80F. Can't imagine our unit doing squat when it's 90F+/70. I think the issue is the high cathedral ceiling/loft area that obviously traps a lot of heat. The indoor unit is mounted ~9ft. Using the IR gun, the top of the unit was 77F while room temp at couch level was 75F. I had remote setting on 64F. There's no way our room will cool to that level, so the compressor will be constantly running right? The bedroom unit was set for 68F on remote and I woke up to the same temp on our room thermostat, so it seems clear to me the new unit is likely undersized and with such a large cubic vol of hot air, the new pump will not be able to do much for temp. Humidity OTOH was lowered to 60%, so that was good and achieves a more comfortable level, but for $4K, I'm pretty disappointed.
