I'll suggest you google up things and terms you don't understand or have a slightest of doubt in them. And read about them on Google. Come back and read his explanations again. You'll be good to go.

Exactly. I installed my friends Oreint 1.5 AC with proper procedure and care - as you have explained here too - and that AC is working like a beast even more efficient than his Mitsubishi 1.5 ton installed by a local mechanic. Even my friend said he never had operated the unit on full fan speed and lower than 27 degrees this whole season. Haha.
@xulfiqar bhai taught me these procedures and helped me while i was working on this DIY. Installed two units after that working like champs.

Why Won't They Perform When You Do A Proper JOB required...These Local Manufacturers Also Don't Put Any Instructions In Their Manuals Now And Leave Consumers In Hands of These So Called Technicians....

Proper Installation Not Only makes It perform Good But Also Increase Your UNIT Life By Many Many Years Compared To That Installation....!!

I Am Also Planning To Install Additional LINE Filter Drier.....As These Units Only Have Strainers But Not Proper FILTER....A Filter In-line Filter Will Prevent All Kind of Moisture Build-up Inside System And Make It Work LIKE CHAMP After Many Years..

It Cost Rs 450..Comes With Both Fitting Ends As Well As One Can Braze Them On Lines If They Want....!

Car AC comps won't work. Vaccum pump is available but its too costly. A 4 CFM pump is worth 45,000.
