Air conditioning - Any recommendations please?? - Part 2

[Ah Ken]

get another isolator, my 2nd isolator trunking goes from DB box to toilet to ac ledge

if you only want starmex this is the option

system 2 btu is 15.3k only, you count the btu from the condenser side not fcu side. but if you want all starmex. this is the option

option1: you get system 2 for the 2 smallest room and system 3 (22k btu) to 2 (2 FCU - fp20vp) of the biggest room (but only 1 can be on at the same time)

option 2: system 3 for the 3 bedroom @ 9k +9k+12k and system 3 with 1 FCU (24k)




if dont mind the brand, many 20k btu can fit your windows, but if you more then 24k btu and single split system for living rm this is the option

option 1: Daikin model (RZFC100DV1G/ FAFC100AV1G) aka 30k btu and will fit your windows as it height is 695mm for living room

Hi bro, thanks for your reply.

For option 2, system 3 is paired for 9 + 9 + 12? The 12k is a default grouping? The 3 rooms aren’t really so big. And for the system 3 with 1 FCU (24k), can I say that you are suggesting using the multi-split system 3 with 1 FCU (24k)?

From what I understand given to me by GC is Single-split system for the living room and I realise that for single split units, the compressors are relatively large. I am not so knowledgeable about this and had all along think as using the multi-split set-up for the living room as I browsing through the PDF and notice the compressors are smaller.

I had also given some thoughts of 2 systems before your post came in, System A: 9K + 9K and System B: 24K + 9K. Does it sound sensible?

For your last note, GC rep did suggest that I downsize to 20K. In fact, my living room had been using a 18K for years. It is a Sanyo unit and performance was ok. No disappointing moments for years, maybe only some drops when many people are gathering in the living room. I was told that day that there is only one 20K option to choose which is Panasonic as other brands don’t carry 20k. I not sure if I am being smoked or what. Suggested by him is to get System 3 for the rooms by ME and living room with Panasonic.

Thanks for your reply bro, hope to hear from you more. I not rushing to get it at the moment since it is already CNY and weather has been chilly so helping us since my A/C have been downed for quite some time already.

hello,

can i do a quick check here regarding the reviews on this 2 vendors; genesis cool and comfort cool

as i am currently doing renovation now and my id suggested us to use genesis cool.

comfort cool is the vendor under my project's group buy.

Am open to other good AC vendors as well.

TIA!

Just a summary for those who don't read the info and ask:
- it's the compressor that matters, not merely the blowers
- if you choose to underpower, don't seek validation here and end up regretting
- do your sums, use the online programs, add additional variables eg open areas, cater to entertaining guests etc
- having a weak underpowered compressor means that the room cools more slowly or never and it works much harder
- save a few dollars on models or contractor and live to regret for years
- pay your man his worth, I'm sure you would pay yourself well if you're in his shoes too, he has a family to feed too
- stick to the traditional brand leaders for ease of maintenance and repair

Good luck!

Yes for option 2 use system 3 as a single 24k fcu cause of your windows height. I not sure multi spilt can support a single 24k port as it gas pipe diameter is not the same, do check their guide

12k for bedroom is cause master bedoom bigger but if your master room smaller 9k is ok.

Single split l is stronger but your windows height limit you condenser size else single 24k is good or unless you ok with smaller 24k but using multi spilt but need to check if can support.

For System A: 9K + 9K and System B: 24K + 9K.

My goal is always backup, I scare heat at night and if spoil how. So ur choice is idea for me as if 1bedroom ac spoil I can sleep at another bedroom with ac cause that is 2nd condenser, best is 2 set of system 3 with 2 fcu each only with 12k or 15k blower and living rm 24k blower. Even under hot sun also not scare

I suggest more btu rather then lesser btu

Like me I get just the right size btu and I am stuck with 25c or 24c max cause if I try to set 21c even after 1.5hr my compressor is on full power, but the fcu is blowing directly at me so it very cold for me and heng 1 install 1 compressor (can see my picture posted in this thread before can check my testing in this thread)

So my 2nd ac will be a lot stronger as it away from me but will find on tb if there any thing to blow the fcu to the living room area but there always stand fan that always work to direct the airflow

hi i am looking to get ME system 2 9k x 2 as replacement for my older daikin.
those who have gotten ME installed within say the last 2 months and felt that your deal , installation quality and experience was good to great please drop your recommendations here.
thank you

 

[a4973]

If I am getting ME system 2 from GC, is it a good idea to buy the extended warranty as well? Do most here buy or not but extended warranty? Thank you

A question, my aircon system was installed in 2 trips, pipings were done in Dec24 and blowers and compressor was installed in Jan25 this year.

Right now, i tested my aircon and there were not cold. I called GC and they got Mitsubishi to come down.

They found gas was leaking and concluded GC did a bad installation and will submit a report to them.

My question is, currently my pipings are boxed up and I believe GC will have to remove the box up to remedy the leak.

So will GC bear the box up cost after the remedy?

did they using vacuum pump on copper pipes before turn it on?
No use any vacuum pump could be many problems

They probably will only help you putty and make good the box up but it won't be up to your expectations. Plus if your box up is not white you need to get it repainted again. Do you still have balance paint left?

I'm in market for Aircon I guess .

Moi parent's place , Aircon leaking gas. Have gotten a quote to do leak test , it is around 500 before gst. Let's say if condenser leaking, replacing a refurbish one will cost 1k before gst.

In this case, I rather replace everything new ?

Currently it is a 4 room flat with 3 Aircon. I'm thinking should I install 4 units (inclusive the one in living room) .

If so, what are the options for me ?

Depends if you need to turn on all at once? If so, System 2+2 or 1+3 works. Depends if all 3 bedrooms are to be turned on concurrently or 1 of it is just a study room to use in day time.

 

[seowbin]

2+2 or 3+1 means need need 2 compressor unit or ?

Either one is fine. My room seldom use now. Must see price. Haha. See who to get cold slower right ?

Yes. A system 4 means you only can use a big unit (living room) + 1 other bedroom concurrently, or 3 bedrooms without living room. But you won't have backup when it is down.

Really depends on how often you need to use it.

I have a System 3 (2 living room 1 bedroom) + System 2 (2 bedrooms) because I don't use the living room ones often unless there are guests and 1 of the System 2 configuration is linked to my study room which I use in the day. The System 3 bedroom unit is for my main bedroom which I use every night.

I have a 1 system aircon (living room) which I seldom switch on. Lately the power trip after 1-2 hours of use for the whole house. After resetting it works fine again with no issues. This happens randomly and the aircon company can't detect anything wrong with the circuit and compressor. Any idea?

If constantly after 1-2hrs there might be some issues with the circuit somewhere, maybe pressed in the bends or what then generate too much heat / overload. Just a guess

Thanks. Initially, I thought it was overheat somewhere but after switching the circuit breaker back on, it is working fine for days and even weeks. Problem occurs if I dont switch on for almost a month than the random short circuit happens again.

Then it might be the breaker that is sensitive / faulty. Change it and observe.

We used to have a short circuit when there is lightning, but not all the time. No high energy consumption usage like W/M, Oven, AC. It's just normal lights and fans as usual.

After we changed the MCB breaker, it is ok already.

I got a feeling most of them are buying from gain city. Because I check gain city price, is almost comparable if not cheaper...
