Either prepare to DIY start to finish or contract out for a complete system. Buying components online and expecting a contractor to do the rest isn't the way to go IMHO.
I did the former for about 1/3 the cost of the quotes I was given. I couldn't be happier but this isn't a DIY forum so I'll end it at that.
Yes it is a practice
Actually, I think "practice" is a very descriptive term for this trade. The equipment we install are not appliances and the end product quality is a direct consequence of the experience of the installer.
Would you want a system put in by someone on their first day?
Would you want a system put in by "I have been doing this for 30 years..it will work" (We cut those roof trusses all the time, )
or would you want the installer who practices his trade by taking pride in their work and making the next install look better, perform better and apply lessons learned?
Give a man a fish, he will eat for a day. Teach a man to fish, he will eat for a lifetime.
Give a man a capacitor, doesn't know what to do. Teach a man to install it, now he knows everything.
I'ev bought auto parts at the dealer then taken them elsewhere for installation (and not gotten their warranty) but I wouldn't try that with anything else.

Saved almost the present year in $$ (can't post pricing). So far I am very happy.
A co-worker did even better. We installed his outside unit and a/c coil. He paid a pro to purge and braze the refrigerant lines. He saved more than half the cost of the conventional route.
I scrapped the old copper and aluminum coils for $53.
It can be done. I would't buy it over the internet as the mfr provides no warranty.
