Just confirmed my order to replace all the aircon from current Macquay (12 yrs old) to Mit starmex sys 2 & 3. Took the older model with 2 ticks cos the compressor BTU is 25000. The new model with 5 ticks is only 20000 so if on all 3 unit it wun be cold enough, I was told. Also I am using the existing pipings to save some cost.

Any reason why mits seems to have a very strong presence here with so many recommendation for it? I always thought mits pays a lot for marketing and may not be that great...

I am currently using toshiba (for 5 years), and will be moving to a new place within 2 years, so looking at aircon again.

Too long to read through all the posts...

To all the experts:

1) What is the best recommendation for a 4 room HDB flat for an air con system (All rooms and living room)

2) What's the estimate cost for laying the trunking, pipes ,etc?

3) The distributor will come over to take a look on how to do the layout of the trunking, etc?

Thanks.

Hi experts, would 24k btu fcu in living room an overkill for new bto flats? Was recommended in getting the 38k btu compressor with a 24k btu fcu for living room. Thanks guys

To qrsy2k,
For 4 room flat, 18k btu is good enough.
5 room flat to use 24k btu.
38k btu compressor is an overkill unless you on all 4 units at the same time often.

To Skyeagle,

1) 9k btu for bedrooms + 18k btu for living.
2) $3k+ - $4k+
3) Usually they will come down for a assessment first before installing.

Hi Terumo, thanks for your answer. If i use MXY-4A28VA compressor will i be able to on both the living room aircon and 1 room aircon concurrently?

Another concern of mine was the aircon in the living room will take very long to cool if i use the 18k btu fcu.

Just change to daikin non-inverter ma56ev1 with x 3 ft25dvm (9000 btu).
The thing was if compare this system with my previous inverter system, there was a bit different with the degree setting.

Current system need to set as 22c then it equal to my previous 24c.

Call the shop, they told me this was the different between non and inverter system.
it will not as cold as inverter system. Is this true? Shouldn't it to be same cold in same temperature setting?

Can I just ask if this Gain City $99 for 5 years warranty is a good, legit idea? Heard it's still chargeable despite the "warranty".

Not to mention GC will jack you on the pipe from 22 to 23 gauge when installing; or was it the other way round. Happened to my friend.

I'm a customer of GC and I bought my second unit in 10 years, never happen to me before and they honor the warranty once when my last aircon was down.

To qrsy2k,

If you on living + one bedroom, its fine as 9k + 18k = 27k btu.
If you want your living room to cool down faster then upgrade to 24k btu.

To tancheeru,
Ma56 is around 21k btu.
It might be been to your previous inverter is 27k btu, hence the drop in btu capacity, thus takes a longer time to cool down.

To baku00,

Panasonic just launched a new series with higher number of ticks.

20k btu outdoor is sufficient for 2 x 9k btu.
28k btu outdoor is for other combi like 12k + 18k or 18k + 9k setup.
