1/4 is too thin, min should be 3/8 insulation.

In a dilemma now - old Daikin System 3 outdoor unit got error H8, understand that it won't be worthwhile to repair as there are quite a number of possible reasons for this error.

The problem is that the old Daikin outdoor unit is only 790mm wide, and I can't seem to find any current models that can fit into this dimension. There's probably only an extra 5cm or so space on the aircon ledge.

Anyone knows of any suitable replacement R22 brand/model which is small in width?

3 fan coil aprox service charge 4 times a year is only $250 ma..

so cheap meh...luckily i did not sign for that 350...

i just checked GC 5 years Extended warranty. they say no hidden terms & condition or obligation. no need to engage them for servicing.
can engage 3rd party to do servicing. but if got problem, need to check if it is due to 3rd party.

and saw their promotion today. got Mitsubishi Heavy Industry System 3 on sale for $2499 with standard installation, is it reasonable price?
according to coolserve and the catalogue, this system (SCM60ZJ-S) has a maximum capacity of 25000+ BTU, but GC list it as 20500BTU..
am confused on this....if just 20500, then not enough for all of my bedrooms.
if 25000+, will be enough i guess.

please help to clarify this...

i was quoted Mitsubishi Heavy Industry System 3 for around 2600$+, with removal of old a/c and piping.

I would like to know whether this Mitsubishi Heavy Industry and the strongly advertised Mitsubishi Starmex are the same or not?

I was told by the Dr. Cool staff that both from the same manufacturer, but different dealer who market it differently.

If so, are the performance of both same specification of their aircon system the same?

Anyway, I just bought a resale flat that comes with Toshiba RAS-3M20UAX5. Searched on the internet revealed that this is a 1 tick non-inverter. My concern is whether this system 3 very power guzzling?

I also have a small upgraded utilty room at the back of my kitchen. The dimension is around 2.3 by 2.2 m, which I intend to use it as my gym room. I'm wondering what kind of cooling system I can install that would not take any space in the room?

Please advise.

Thanks.

Yeah it is the smallest, but for toshiba, is it true that warranty is void if installed using old R22 pipes? I'm hearing conflicting info from different companies.

Nope. Warranty won't be void. The pipe is the same. Only refrigerant is different

On the topic of insulation. I'm using 3/8 thickness insulation and the insulation is sweating and dripping onto the trunking causing mould to grown on the outside of the trunking. Will changing to half inch insulation do any help? I'm thinking of doing it myself.

Thanks, so far, Gain City and Coolserve has advised me that there will be no warranty from Toshiba if I reuse my old R22 pipes.

Called Toshiba service center to check, and the response was that their units should never be used with old R22 pipes.

Would be great if there was an official publication of their warranty terms. Don't know who to believe now.

Edit: Btw, GC staff advised me that only LG, Panasonic and Mitsubishi Starmex officially covers their warranty for reusing of old R22 piping.

3/8 inches is the minimum requirement for Insulation. Even if upgrade to 1/2 " it will only reduce and not prevevent. Sometimes its a user problem bro. Room 2 or 3 switch on aircon. Master bedroom dun. Condensation cfm appear

Bro. I have checked.. reusing of old copper tubing tat holds r22 gas is reusable and it does not void the warranty of the equipment. UNLESS the installer cannot make it la...
