Yes, it is a non-inverter. All the air-con guys who came to view and quote me said that the compressor for Inverters are too big to be shifted out of the window to the air-con ledge outside.

Except maybe the D@ikin inverters. But then D@ikin inverters system are way way over my budget, so I decided on a Panas0nic Envi0 System 3.

Ok, thanks for all your advices, I will definitely apply for a day's leave to see that they do not cut corners. But then again, how can we know that they do not "anyhow bend the copper pipings" till the copper pipings are NOT cyclindrical anymore? I mean I can see the pipings after they bend it, if the pipings are still cylindrical or not. But then what are the "proper tools" that they should be using?

Also, if on the day itself, if I see that they anyhow bend the pipings and the pipings no longer is cylindrical in shape at the bends, can I point out to them and request them to use a new pipes to re-bend??

I mean I scared, later those air-con guys will give me that "don't teach a father how to corpulate" type of face and attitude...

Sorry if I am asking a lot of things at one go.
for 9,000btu FCU liquid & gas copper pipe, actually almost all the installer use hand to jus bend the pipes. so shouldnt be a problem. to how they bend the pipes, i tink by jus a look, u can know they got anyhow bend or not. since it is a G22 copper pipe, it wil be very thick. so the bendin shld be nice.

but than, it is NOT recommeded to cut the copper pipe n join another in. as in joining 2 together. this wil causes leak. n majority leak problem is becos of copper pipe joinin together.
