one more thing, to be suspected on compressor or indoor fan motor an issue..
if system 2 and above still can check on each room and compare the airflow does meet on each room, if few room still the same way and blowing hot air, then the only way for claim on new compressor will do, unless the service guy they has touch the outdoor connections before.
Topup gas today (47th month,~yr4)..actually realized also had a previous gas topup at 25th month also.
Service guy explained gas topup ~every 2yrs can be expected..unlike fridge which is sealed system, aircon has nut connections at compressor and FCUs, ie prone to leaks over time.
I intending to have 4 aircon units (3 bedroom + 1 living rm).
Main use in MBR for now (and likely won't use it every night, some nights just use to cool the room down etc); living room only when guests over or super hot day or haze day.
Should be getting ME, but not too sure in terms of configuration.
Should I get one system 3 (for the 3 BRs) + one just for the LR; or a system 4? The 1st setup cost like 1k more, is it worth it cos will save electical bills compared to system 4?
And if system 4, is 3A28VA enough? or need 4A38VA ?
Looking at 9k for each of the BRs and either 18k/24k for the living room.
Also, let me know if any special promotions or sale for aircon ongoing now, shd b buying in the next wk or two.
Thanks much .
Hi Kim and Terumo, my questions is very similar to Gaoz7 what about if my isolator is based on 20A?
Does that mean that i can go for the 4A38VA?
Can i also know what are the pro and con or getting a system 4 vs a 3+1 in this case if i mostly on the mbr aircon at night at 27 degree?
By the way, it is advisable to turn on fan mode without the aircon to treat it as a fan?
I looking for a system 3 that is long lasting. My current System 3 Mitsubishi Heavy Industry died on me and the current Mitsubishi Electric aka StarMex have condensation issues after 4~5yrs.. anything to recommend? I planning to replace the piping and everything.
My aircon guys wanna do system test again and it will take months to resolve as suspect leak on the piping. I just dont trust them and want the nightmare to end!
Btw Best Tech service SUCKS! The piping skill is rubbish... This is not the 1st time.
I thinking of Daikin but dunno the service is good with fair price.
Everything was related to workmanship, a better job done, even 5 to 10 yrs still not an issue.
Just depend how is the exprience when they connections the nuts, some they worried to fall down with compressor together rather than quickly done and didn't check with bubble test before to handing over.
So the future has many troubleshoot to be solve.
Makes sense. I also feel topup gas every 2yrs is not quite right.
Qns seeking advice (Thanks!):
1. Should I do a leak test & rectify? How much does a leak test cost?
2. Is leak test also done at FCU end?
2. I had reused small sections of R22 copper piping as these were concealed, could this contribute to the leak?
If your block electrical loading has been upgraded, then you can install the 4a38, if not, its advisable not to.
Hope so..do rmb maintenance 4times a years is a must for GC warranty and have to be BCA approve and have to keep the black and white receipt to show when have problem with the Aircon within the warranty periods.. many bad after sales service heard from many friends
