I think this one is pretty self explanatory.

Great for making it 'easy' for homeowner!! Also must have been drafty as there does not appear to be mastic or foil tape sealing seams.

Any filter access from the other side?

Also, where the liquid line enters the cabinet, that will surely be a leaker. The copper line is rubbing on the metal knockout and with the way the cabinet vibrates it will only be a matter of time.

No access from the other side, the unit is in the attic, and butted against the rafters. I didn't even notice the return line rubbing the knockout! thanks! As far as the cab being sealed, they used a foam tape at the joints (not clearly visible in the pictures though). Luckily there is a filter at the return vent so I just recommended removing the filter from the handler all together.

Furnaces are often installed in attics and crawls around here, I can not tell you how many times I've pulled the original filter out of a 10 yr. old furnace, handed it to the seller and said "It aught to run better now". The look on the sellers face is priceless...
