hey guys..

anybody use the "dry" mode to perform cooling
does it actually uses less energy then "cool" mode ?

if dry n cool works the same why do they include both ?

Really sorry for the confusion. Actually I need to install 7 units of aircond : 1 2.5HP Cassette (according to my contractor, the installation cost is the same as 3HP, so, he quote me 3HP price), 3 1.5HP and 3 1HP. Very headache now. Install aircond also damn expensive!
Thank you!

Thanks for the contact.

How many wires will be use in aircon?
My contractor only install 3 wires & all wires & piping already concealed.

Hi sifu, i need some advice here. Anyone have their home with installed ducted type aircon? I need some feedback about ducted type aircon about their cost of installation and ease of maintenance with compare to ceiling cassette unit and wall unit. Pls provide me some guidance..kind of lost here. It is to share among my dining and living room. 2.5 or 3 hp should be enough. Total area is 22 by 18 feet.

1. How do I know for sure that my piping is leaking? Any professional contractor that can do the detection? I'm trying not to do the hacking and rewiring if at all possible.
2. Any recommendation of a professional air cond service / repair man that can do all this including the electricity wiring? Because we need a x voltage wall socket for this 2 HP a/c unit.

URGENT! A good and professional a/c service / repair man needed, hopefully can work before CNY 2013. Please recommend.

Hi,

What is the difference in size of an aircond if the cooling power is the same? I want to install 2.5HP ceiling cassette aircond in the living and dining area but the cassette have many different size panel 900mmx900 mm, 750mmx750 mm and 600mmx600 mm?

Does it give any effect on the cooling and electric bills? Any sifu can clarify this? 

Thanks for the info. I'm planning to install the mini cassette for my living room. The large ones is too big. May not have enuff space to accommodate it. Not many are selling the compact ones. Planned to install daikin but they don't have the compact ones. Now saw Hitachi have compact cassette but don't know for sure how good or reliable they are. Their split type are good.

Anybody using 3hp a/c at home? This a/c seller advised me not to go for 3hp for home due to standard wiring cant take the load. Anybody got experience on this?

Abnormal size. Will have to pay premium for parts n labour next time.

2 hp blower is already quite large and sufficient for my landed living room, so I think it should fit yours unless you stay in a big bungalow with loft ceiling.  If you need higher hp, I suggest you mount another 1 hp or 2 hp at another location for more even distribution of cold air.  Else it will be freezing cold at the 3 hp blower and warm at other dead corners.

Yup.. its good to have a few small aiconds rather than 1 big aircond.

Skng03...thanks for the reply. How long have you been using the 3hp unit? Your place is single phase or more?

I was told by the air con sellers that cassette type are high maintenance, else they will leak water easily.  In addition, you need deeper false ceiling.  I used wall mounted to maintain the height of my loft ceiling.

guys i need to advice here, my 1 week old Mitsubishi 2HP non inverter aircon just failed, only blow strong air, not cold at all. Asked the mitsubish technician come check and he told me my house piping and wiring are not for 2HP aircon. and the wiring already burn so the compressor won't run. He can't do anything because warranty only cover indoor blower unit and and the outdoor compressor unit.

So my question is, other than pipe, wiring for 2HP aircond also different?

I am n00b in this electrical thing but the installer should tell me it is not compatible, they should know right?
