I asked this question yesterday and was told to check pressure, I am trying to get the person that is certified who help me install the unit. He did pull a good vacuum on the unit and held it there for awhile when he installed it, but never came back to check pressure after a few days of running. Will it help if I put more air returns in my house. I was thinking of installing another vent in the ceiling and use a flex hose to tap in the large air return duct in the attic.
