“Installing 1-ton Blue Star AC with outdoor unit two floors above — piping length and cost?”

Hi everyone, I’m planning to install a 1-ton Blue Star split AC. My indoor unit will be on the 5th floor, but the outdoor unit will have to be placed on the terrace above the 7th floor.

Does anyone have experience with this kind of installation?

•	How many meters of copper piping did you end up needing in a similar setup?

•	How much did the extra piping cost in Delhi?

•	Are there any things I should watch out for so installers don’t overcharge or skip important steps (like vacuuming the pipes)?

Would really appreciate any advice before I get it installed. Thanks!
