Performed a tune up on the hvac equipment. Testing system operations, component amperage’s, capacitor ratings, changed the 2 larger filters, cleared both drain lines, and tested the thermostats. The systems are both cooling properly at this time, one down to 46 degrees and the other to 48 degrees. I will email a proposal to replace the 2 supply grills downstairs and seal lower attic interior wall with a sheet of duct board.
