I bought a new Hitachi split AC lately which isn't cooling as much I was expecting.
I checked for leaks/bad installation and found this.
(This is connection point of external pipe and pipe which came inside split)
As per what I have studied, it's important to insulate the big pipe at least.
I have two questions:
- As this part is next to the split section aka inside a room, to what percentage can it affect cooling?
- What should I use to insulate this joint? Would Aluminum Tape do? There are very limited options available here in India. I found this aluminum foil shielding tape on eBay. Would this do the job?
