Thank you. Confirmation that the contractors messed up when they originally installed it and that the A/C contractors didn't notice it either. This house has had some unconditioned and unfiltered garage air blowing through the vents for the last 11 years. I imagine this reduced efficiency not to...

Maybe this helps illustrate the problem better. You can see the filter at the top and the vents open to the garage which pull in garage air after the filter. This can't be right. Here is the only spot in the installation manual that shows those vent holes and they are only shown on the supply...
