The fun (or not so fun) part about Daikin five stars, having bought 4 for my apartment back in 2012, is that while they perform, they perform like champs. However if something goes wrong, they cannot be “serviced” as such – main board replacement is the usual thing. The older, cheaper models can usually get their boards repaired locally.
The other part is they are extraordinarily sensitive to power fluctuations. The old fashioned two or three star ones with copper coils are not energy efficient, but they cool a lot better and are a lot cheaper to maintain when they go wrong. Whether that is offset by power bill savings is something to be determined, we wouldn’t use all the ACs to the extent that they’d be used in a factory.

I think I'll buy BLDC fans for the factory. We changed our acs to Daikin 5 star a couple of years ago. I think we've recovered the money already from the savings Thanks and regards Narendra Shenoy On Tue, 27 Apr 2021 at 20:20, <[email protected]> wrote: > Not sure I've scanned the full list.
