How much is the labor and transport
If I remember correctly $107 for first fancoil, if multiple equipment failure, subsequent units will be at 50% of $107. Not sure if the price applies to outdoor unit tho, should be cuz the guy who picked up my call asked me to spell out the model number for both indoor and outdoor unit.

And for your info, it is clearly stated in the LG artcool fancoil installation manual that min clearance from TOP of fancoil to ceiling is 200mm. Only saw that in the manual after installer left. LG emphasizes this with a caution mark stating that cooling capacity will be reduced as well as increased operating noise if 200mm clearance is not met. Which is kinda true for me now. I surveyed the fancoil and I think nowadays, even for other brands the only air intake is at the top of fancoil. So if the min clearance is not met, air intake will likely be restricted especially when you go for higher fan speed.

I have 3 fancoils installed and only 1 unit has that min 200mm clearance.

The other 2 fancoil installed with the installer's presumed adequate min clearance of "3 inches" .

If u have L box at your living room like mine, it is really not practical to achieve 200mm clearance between fancoil and ceiling because if u follow the guideline strictly, your fancoil will be too low.

power consumption is good, a 6yo 318L non inverter fridge running together with the aircon system at night averaging 8kwh per night (readings at power meter recorded). 10 hrs usage (9pm to 7am) for my 2 common rooms 12kbtu + 9kbtu, set at 25deg C, reaching target temperature less than 20mins monitored using digital thermometer.

I hope the LG system will last me at least a 5 years. (Praying hard)

my starmex single split 12k btu inverter is already dying on me now, and it has served me for only less than 3 years.

I recently changed my aircon. My previous aircon was ard for 13 years. Compressor not as strong as it used to.
When the installers dismantled my old aircon piping, the piping was still in good shape, no holes, no rust, no leakage, and its the smallee hole pipe, not the much touted big radius piping. Even the sponge was in god condition and its a no brand sponge..
My conclusion is that its not always the material that matters, its the installation that matters. You can see the installation was done meticulously.


Anyway i used coolserve as my installer this time round. Been three weeks and no problem

Is there real need to upgrade to the thicker pipes n insulation? Very reluctant to remove existing trunking which will be a huge mess to reprint

some installer wont give u installation warranty if you reuse existing pipings

depending on when did u install the previous set of pipings and if you have upgraded them last time. installer advised me to upgrade to thicker copper pipe and insulation so i can reuse them for my next system change... lol not sure BS me or not

I'm ok to replace the existing pipes and insulation to same size. Think is 1/4". The upgraded version is 1/2" and if I change to that, I will need to remove my existing trunking and change to bigger ones to house the bigger insulation pipes. I prefer not to do that so I can avoid repainting the new trunking.

Just trying to understand the criteria for the bigger pipes and if its absolutely necessary.

was in the same position as you 3 weeks back

if you wanna use back the existing trunking, then you can go for the standard copper pipe and insulation package w/o upgrading them.

the key point will be the workmanship, cuz thinner copper pipe wall thickness is easier to kink if the installer just bend them using bare hands and mind you most of the installers will just bend the pipe bare hand cuz using proper pipe bender is very very time consuming for them (easy way out)

insulation wise, my installer was saying 3/8" is adequate, and insist on good brand like armaflex class 1 or 0, but still i upgraded to 1/2" lol. he joked that he don't understand why singapore households like to upgrade the piping and insulation package to "industrial" standard (unless you wish to keep the piping for your next aircon system change especially for condo if you need to strip off your renovation just to change the pipes), some even went for 3/4" insulation

Natair builder for LG a little bit cheaper. But upgrade to better insulation and pipes about the same. But netaire has $300 choice voucher and 5 years warranty on parts.
