Disconnect behind the condenser is no good, the mastic looks horrible, AHU not properly hung, refrigerant lines look like they are run in downspout bought at Home Depot. I CANT STAND CONTRACTORS THAT CHEAP OUT!
Foil tape on the AHU looks terrible, not to mention its not necessary! American Std. has a nice gasket on there AHU's so that you dont have to do that kind of crap. I would not be proud if that was my work.
tape is horrible, not needed on a new unit, especially a Trane/American standard....we also have to hang the units as well as the drain pans. You should have made a proper transition for that supply, you have a lot of dead air there causing turbulence. Duct sealant should be used for the tape seams only. The condenser should have been moved over to clear the disconnect. We are required to have 3' clearance in front. And that rain gutter for a line set cover is hideous
I hate to pile on here but, yeah, its just not a good looking install. Lots of good advice even if its "tough love" Every time I see silver tape all over an air handler I just sit in the attic and weep over my sliced up finger tips hahaha
