Workmanship also plays an important part, other then materials.
Need some advice.
Understand that it's probably better to buy from Daikin Pro Shop or Cold Engine/Air Connection for better workmanship and maybe better materials.
But if I only want to replace system 3 aircon but using back existing piping, does it matter if I go to Daikin Pro Shop/Cold Engine/Air Connection or other shops (eg. All Best, Gain City, Best Denki, etc) since I don't need their piping anyway?
