Who can tell me about air conditioning parts or lead me to a good diagram?
We are trying to fix the air conditioning at work (the landlord won’t do anything) and need to replace some parts. We have the ducts and I have found out that the ducts are connected to the collars (male/female). The collars are then attached to a big square piece which then has the grille attached where the air goes out. Does anyone know what the big metal square piece is called? I’ve been looking online but so far, no luck.
And if you know of any good diagrams illustrating this, that’d be great as well.
Thanks!

You are referring to a supply air plenum. And the grill piece is called a supply register.
The box is called the boot either a PH1, PH2 or PH3.
The very large box at the unit where the ducts are attached too is called the plenum, either the supply or return.
