When it is 40 degrees outside, it cools to just 35 degrees. When it is 35 degrees outside, it cools to just 30 degrees.
Also there is excessive noise above our master bedroom when zone one is used. We have also noticed hot air has once again started to come out of the chute opening.
Kindly send your representative on a hot day to check the same.
