There are several air con threads. Best to ask moderator to merge them.

My sister bought a new condo unit. Cables for a/c were pre-installed.
Recently asked an air-con installer to go to have a look. He said the cabling is of 3-wire type, so can only install non-inverter a/c or Panasonic inverter a/c.
Also, he said we can only install 2.0hp a/c in the living room, not more, not less.

Are there such restrictions

Stock market boring, so master cherroy now talks a/c liao

I talked to the technician of condo contractor. He told me that the pipes can be used for both inverter and non-inverter types. (I suppose what he meant was R410 and R22). However, max for 'new gas' is 2.5 hp, while max for 'old gas' is 2.0 hp.

If pressure for R410 is higher, isn't that we should use smaller hp a/c

We can buy Thailand-made Daikin non-inverter in Malaysia?

May I know if 1.0 hp is good enough for a room measuring 16 feet x 17 feet (including bathroom)? This room faces east.

Of course, when the aircon is on, the bathroom door will be closed.

Master bedroom 1.0 hp enough?
