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 Edited December 1, 2017 by Don Yang typo and add pictures Share this post Link to post Share on other sites
