Hi everybody
im currently renovating and have just installed the aircon piping. I notice the aircon contractor install the both copper piping in only 1 insulation from the compressor to the fcu.
I've question their installation and they told me that it is their company standard to lay a single insulation and share both copper in 1.
Is it a standard practice and acceptable?
it is stated to upgrade to 1/2 insulation, but seem like it's only 1/4" on some part
pleaae share your advice and experience.
thank you
