Hello everyone, I am looking to purchase and install a few Mitsubishi Electric airconds for my landed house (12 years old ACs).

1. It is concealed piping. Do I need to hack the wall to redo the pipings or I can reuse same pipings? Old ACs are 410 type and I'm looking to change to R32 types.

2. Does anyone have installer contact that's good for Mitsu AC installation?Are installers attached to a single brand? (ie Mitsu installers would only install Mitsu airconds?)

Dear all, for my hall - I am considering between a non- inverter or inverter 2hp air cond. Since my living room is 40ft x 22ft rectangle design with dining area, I assume having an inverter air cond is not more beneficial than non-inverter as its unlikely to achieve the set temperature due to the open concept of living room.
