Sigh, just found out that my condo's aircon carbon piping installed is the thinner one.

I guess maybe need to settle with Daikin Inverter R22 airconditioner now...... Hopefully pricing wise will be cheaper but wondered if anyone's using it and power consumption the same as R410A ones?

Just wanted to query.

My air con installer insist that he should hack the wall and check if the copper pipe is bended (my developer got install those wiring, pipe etc dy in the wall).

Should i just tell him to just install the air con and not hack the wall?

Thanks!
