thanks.

starmex sys is standard with mxy3a28va as compressor then the 3 fancoils you choose what btu you want. the $2799 from all 3 contacts are 3x9000btu fancoils.

Hi all, any recommendations on air conditioner system 2? Budget around 2k. Most important factor is to save monthly electricity. Usage roughly is 6 - 8 hrs daily. Thank you for all your help!

To lazypigx,

Can get inverter sys 2 with ur budget.

Hi guys, the compressor for my old Toshiba RAS-3M20UAX5, which is installed in my master bedroom is jammed.

the technician who came down to check, suggested to me to replace the piping to the other working compressor and terminate the usage of one of the aircon unit in one of the room.

he said that it is not worthwhile to repair the compressor and it doesn't come with warranty, and there's no guarantee that it will work after it's repaired.

so may i know if this is the best available option, other than replacing a new system?

Hello Eyz,

What your contractor suggested is to do a switchover by isolating the jammed compressor and to connect the master bedroom unit to the other working compressor. (Non inverter)

You will have to sacrifice 1 common room so that the outlet can be used for the master bedroom.

What your technician mentioned is correct as most 2nd hand compressors does not come with warranty. Only warranty would only be for the workmanship and not the compressor itself. Also, most probably as the compressor was jammed and not running, it means that he is unable to test the system completely to detect other underlying fault hence he would not be able to guarantee if changing the compressor would make the whole system work again.

Based on the model given, the unit should be around 7-8 years of age? Basically you do not have much choice as compressor replacement does not come cheap and most probably not cost efficient to do so much repair on an old system. However this would be up to personal discretion.

What you could most probably do other than to change a new system would most probably be to get the most competitive pricing for the 2nd hand compressor replacement. Other then that sacrificing the aircon of 1 lesser utilized common room and opting for the switchover might be the only other way.

Personal opinion I would consider changing a new inverter system as this is an old 1 tick non inverter.

Hope you have this resolved soonest

Hi

thanks for the detailed and prompt reply.

anyway, are there any way to direct power up the compressor, so as to determine that the compressor is really jammed?

the gaincity technicians ever came down to diagnose my mom's place aircon. they did a direct power up to the compressor, so as to determine that the compressor was not faulty.

however, when i suggest to the technician, he didn't get what i was trying to say and went ahead with the switchover.

anyway, 2 of my 3 fcu is unused. i guess i'll just leave it as now.

a fellow forumer suggested me to check with toshiba for advice, i guess i'll check with them at a later time.

anyway, i asked the dr. cool asia technician for advice on a system replacement. judging from my current setup, he suggested a daikin r22 system 3, which would cost around 2.7k.

the main problem lies with the piping from the mbr, where goes through 2 built-in cabinets. pictures attached below:-







in order to change the piping, the built-in cabinets would need to be removed. if existing piping is used with a r410a system, sweating might occured.

any advice on this?

anyway, does aircon installer help to plaster the wall nicely after the installation?

Hello Eyz,

Yes you are able to directly power up the compressor to determine if the compressor is really jammed. However most of the time this would not be necessary as technicians should be able to measure using multimeter and coupled with experience they should be able to advise if this is really the case.

However since the switchover has already been done and 2 of the 3 FCU is unused, then you should most probably leave it as that until the last compressor fails before looking into a system replacement.

Concealed pipings are usually a factor to consider during the replacement of aircon. The hacking would be costly and a hassle.

If you are looking into replacement by using back the old pipings/insulation, then Daikin R22 gas model 3MKD or MA56 would be the ones that should most probably fit your requirements.

To use back the old pipings would mean taking a risk on sweating pipings/gas leak and if you choose an inverter running R410A gas, the gas pressure is much higher as compared to R22 which means that your old pipings might not be able to withstand over long periods not to mention the flushing and prep work required to have your old pipes ready for the R410A gas.

Other then that a new system would be expected to last at least 7 years with proper maintainance. It would be a gamble to have your old pipings last that long. Personally I would not prefer to use back existing pipings if possible.

Plastering of walls would depend on individual contractors that does installation. Some might plaster over with white cement however the painting you will have handle. Best to check with the one that is handling the replacement for you.

Drop me a PM if you have more queries.

All along I thought Daikin air con was a lot more expensive than Mitsubishi. But according to my ID, its only about $100-200 more? Is this true? Assuming he is right, would you invest in a Daikin or Mitsubishi?

I have a relative who is quite knowledgeable about such stuff and he said Daikin is better. Reason is they only make aircon so they are more specialised. But my ID said from his experience Mitsubishi is better.

What do you guys think?
