Does anyone know if it's worth going for a high COP configuration for Toshiba?
Seems like a trade-off between cooling capacity and electrical consumption.

yup, higher COP means it is more energy efficient, but from the figures also means it will take longer to cool the room down to the same temperature.

The efficiency drops when the compressor is operating at maximum capacity or overloaded. Similar to efficiency curve on a computer PSU, where the highest efficiency occurs at 70-80% of the max capacity.

Getting my installation from Best Denki soon. If the old piping is still in good condition, should I still change to new piping?

Old one: Sanyo R410A
New one: Mitsubishi R32

Condo concealed piping
Cost of installing new pipe: 3 holes plus longer pipe charge is about $360

You suggestions are appreciated. Thanks.
If only Sanyo air cons are still available now. Both Sanyo are National were the best brands and can last really long.

Coming to your question, it is best to change to new pipings but concealed pipings are more complicated.

Got to check with your installer for better suggestions.

removed a room for a bigger living + dining area -- about 46 sqm

one retailer recommended a system 2
3M41U2ACVG / 18000 btu x 1 + 12000 btu x 1

while the other recommended a single light commercial unit
RAV-GE2501KRP / RAV-GE2501AP-SG

any opinions?

you may want to check if RAV-GE2501AP-SG can fit through the window at the aircon ledge, it is a big unit.

Thanks for the reminder! Outdoor unit will be ceiling mounted in the yard, but i’m now considering how low it ends up

Is it easy to DIY cleaning of Daikin iSmileEco's aircon blowers?

Tried calling a few retailers but nobody has any idea on when Mitsubishi Starmex R32 models will be available.

this was 1 of my consideration when buying....
should be batch issue...see luck ba. i ask the technician also no said got this issue.
if really that bad, people already flip flop liao.

if super unlucky, 1 year die
if unlucky, 5 years die
if lucky, 8 years without issues
if super lucky, beyond 10 years....... praying :)

Which system 3 can do 9K+9k+9k comfortably?
Are gas R410 and R32 using the same pipe? If you install for R410 can the pipe be reused for R32?

Assuming the same outside unit, is it better to use 1 18k btu fancoil or 2 9k btu fancoil units for a living room? To be paired with another 9k btu fancoil unit for another room (i.e. to go with System 2 or System 3)?
