Sharing what i know and learn so far, i try make it in point form to keep it simple:
contact 4 company:
letscool
amyth
aircon rescue
newway
my shortlist are simple:
look at google bad review (or any other source) only, the bad review date last posted how often bad review is posted
materials
materials :
letscool quote me : SWG22
amyth quote me : SWG22
aircon rescue quote me : SWG21
newway quote me : SWG21
the price all 4 are less then $40 different
all other almost the same of 1/2inch, copper wire almost same core and number of wire etc..... so my shortlisted are aircon rescue and newway as they quote me the correct materials (i started a thread talking about the copper thickness)
i choose newway based on google (or any other source) bad review feedback or lack of (as explain) aircon rescue no cause not much of any feedback from any source (it a new company)
after the piping is 80% done, i go take picture . i take this drain pipe like very little insulation when he saw me take picture he redo (or maybe he already want to redo i dont know) but happy he did redo cause the next 3 to 4hr doing the piping from 3.30pm until 6.30 to 7pm++++++
more checking, so far so good after that strange redo
from here on, all is good, everything is good, dont even need to open mouth liao
drain pipe no join connector but using heat to pipe and install with insulation at blend area
video about layout(before drain pipe redo), vacuum and doing the soap test to check leak , installer auto use soap to check for leak on their own unlike my first installer who dont even vacuum and do the soap test

last step, they even add rubber on the condenser leg, (this is not needed at all, some may first it a cons if the rubber wear out) i feel adding it, doing the soap test show their professionalism
workmanship issues take time to show up, can be weeks to year. but so far everything look good for now
