The last company that I talked with recommended moving the return registers on the second floor of my house from the floor to the ceiling. The cost is minimal when compared to installing the system.
We have always had issues with keeping the second story cool and he thought by moving the registers to the ceiling this might help.
We have a 1994 Bryant A/C so I know the new system will be more efficient.
Should we wait until after the unit is installed to see if our cooling problem is resolved?
My wife doesn't really want the registers moved to ceiling height due to the aesthetics but if it would really help with the cooling she might be game.
Again, we are not adding registers just moving them from the floor to the ceiling and I don't know how big a difference this will make.
We added insulation in the attic so we should have about a R-49 insulation value in the attic.
