So u also installed by Gain City? What insulation u using? Any problems with their insulation? I feel worried coz the guys like doing things anyhow. A bit worried.
so far so good... at least they did a much better job than my previous free-lance contractor.

the insulation given was Amaflex, should be the same for all GC bah... But i upgraded to 3/4" thick (kia-su singaporean) coz i had severe condensation issue previously.

no... unless the rubber insulation covering the power cables to the FCU cracks/breaks, which is highly unlikely, if so then most of us would be in peril by now... hehe

hm.. this is strictly my own views k?

i think the old Fujitsu had very slim/small FCU which impeded the the transfer of 'coolness' into the room. The result was cold gas in; cold gas out. And sweating was common, at least for me and another close friend.

GC told me that the newer Fujitsu model has oredi addressed this issue, and for what i see it is larger than the older one.

but one bad experience was enough for me... i went for Toshiba.

What about Daikin? Have you enquire the price for it?

the newer Daikin inverter sys running R410A is Expensive

sys 3 around $3.4k

the older 3MKD75DVM / 3 x FTKD25DVM running R22 is cheaper. around 2.7K

Anyone using Mitsubishi Heavy Inverter Sys 4 ?


Model:
1x SCM80ZG-S (Outdoor Unit)
1x SKM28ZG-S (FCU)
2x SKM35ZG-S (FCU)

I was quote $3580/- with the following items / materials:

- Stainless Steel Bracket
- Totaline Copper Pipe (Unknown Gauge)
- 1/2" Grade 0 Insulation (K-Flex)
- Totaline wire 3 core / 70 & 4 core / 40 (May I know what is this ??)
- PVC Trucking
- PVC Drainpipe (16mm)

- 2 Trips Installation
- Dismantle existing air-con


This is outdoor unit very noisy ? I read the spec it say 66db.
What is the normal noise level for a 32k BTU Condensing Unit ?

tat 66dB is on full load. tat means the sound level wil only for a short period of time. once the room reaches the temp, it wil reduce to part load, thus sound level wil also be reduce.
