Help : Aircon Planning

[genesis 0]

Hi Warrior88,

I got the following for the bedrooms :

MASTER BEDROOM

==============

BTU = 9275 (2.71 kW)

BEDROOM 2

==============

BTU = 8327 (2.43 kW)

BEDROOM 3

==============

BTU = 8327 (2.43 kW)

Hence I go for MSXY-GA13VA (3.5 kW) for Master Bedroom, 2 x MSXY-GA10VA (2.5 kW)

for Bedroom 2 and 3.

I understand Bedroom 2 & 3 might not be cooling enough but from experience, I normally

set temperature to 26C lowest since these 2 rooms are my kids' rooms and we normally

don't make it too cold. Hence, I doubt there will be cooling problem.

I might be wrong here but worse case, I can still opt for 3 x MSXY-GA13VA (3.5 kW). Will

talk to the aircon seller and see what they recommend.

Hi Kst,

You might just want to consider using just one condenser MXY-4A28VA or MXY-4A38VA , both able to support 10+10+13+26 . Most of us don't turn on all the fan-coil , looking at your case I believe you might only use 3 fan-coils together, however, I think MXY-4A38VA meet your requirement.

the installers must hv integrity and not cut corners when installing. to avoid future leaking problm, owner must be around when they install the piping and most imptly, be there to witness the whole process of pressurization.

Leen, thanks for sharing all your aircon links! what must we look out for during the pressurization process?
