I didn't mean to imply that he should install it himself from an on-line source but just to show him how far off that $16,000 quote was if you just consider what the unit costs.
What I like about them is the efficiency, no loss in ductwork, easier installation, and being able to control separately in each room/area.
I'm sorry I didn't mean to imply anything either. I just wanted to explain some other things about them. They are great units especially in certain applications. But he definitely can do better than 16K and get a quality install done. I just want to see him get the best deal that he can be happy with for the short and long term.
