Really appreciate all your responses and helpful advises.

Previously also thot it was jelly & dirt that clogged drainage. Did declogging with chemical twice plus pouring hot water as advised. Also tried vacuum process.

After above treatment, the water still drip during operation.

Sorry to trouble all of you.

so when you pour the hot water, did you observe the water flowing 'freely' out to the drainage?

Yes, the hot water did flow out but slowly. Is there any possibility that there is condensation on the cooling fins?
At present just live with it. Every night just put a small container to collect water droplets. The amount collected is about 500ml, lesser than 2 drink cans.

Thanks again for your concern. I appreciate the many concern buddies in this thread.

firstly, you're welcomed. we're all here to share experiences and learn from each other.

condensation on the cooling fins is CONFIRMED, it's all physics and so happens on all FCU. that's why there's a pipe to drain the water.

usually, air-con maintenance guys would take a jug of water and pour directly into the fins and observe if the water is drained out smoothly.

for me, i would remove the FCU cover and observe exactly where the water is coming from. 500ml imo is a lot and suggests clogged drainage, but you mentioned declogging with chemical was tried... hm... ask terumo. =:p

Aircon above head

HI All,


I have considered all posibilties and I have no choice but to place my aircon above head.

WHat you guys think? Is it okay? Any possibilty of leaking and water droplets fall onto our heads?

In terms of cool air coverage, is it effective and cooling for the body?

Currently my aircon is by the side, but for my new house, no choice but must be above head.

YOur comments and experience please.

The water leak or condensation should be caused by dirty fancoil which requires general or chemical service most likely. If drainage pipe is not choked.

appreciate any advice...how much % electricity savings would i enjoy if i replace a 10 year old Daikin Inverter with a brand new Daikin Inverter?

Is 20% a reasonable estimate?


I think its more than 20%. I changed my MA56EV1 to a 4MKS80ESG and i was pretty surprised the drastic drop in my electrical consumption... but everytime we on the aircon, we will turn on the wat econo mode, so far haf not tried without turning on la...

As above... looking into air conditioning 3 bedrooms and the living room.. my contractor quoted me $3.7k for a 4:1(2 compressors inside) toshiba system with inverter.

is it expensive?

any lobang/recommendations?

is daikin or mitsubishi better?


Toshiba's parts are harder to get compared to other brands. Their design gathers lesser appeal compared to other brands, like Mitsubishi.

You'll have a better chance here.

There should be some choke at the drainage i suppose 500ml per night is quite little actually. As a rule of thumb, condensate water is about 1 litre for every 2HP cooling per hour. :)

Hi Guys, planning to get a Daikin or MEC or Panasonic system 2. My MBR is 16ft x 10ft. Shud I get the 11k btu or 9k btu? Usage is 8-10 daily for the MBR.
Also I have checked a few site on BTU calc....most of it recommend 9k btu and some 11k btu. Thanks.

To Slayer1, your room requires around 7.2k btu. Get 9k btu should be enough.

Thanks to xseanyx.

I guess there is a little choke somewhere along drainage line. So if drainage flow slower than condensation amount, it will caused overflow.

Last 2 nights there is no overflow. Hope it stays that way. I am using 1.5hp.

Thx

yes. 23 is more thicker than 24. as inverter hav higher pressure, thus need thicker copper pipe to prevent leak.

Thanks terumo. Been searching the web for BTU calc, most of it points to a min 9k btu. Thanks again.

Hi Bro Core2max,

Your extended warrt by itself is how much?
It covers all faulty parts?
Any fine print like wear and tear not covered?

Forgot the details... must check the receipt again.

if i am not wrong, the cost is $300+ (for additional 4 yrs).
It covers all faulty parts. If they cannot get the parts, they will loan me temporary aircon (until they can fix it).
