Hi guru:

I am staying in condo. And current air cons system is about ten years old already.
All pipes are concealed inside false walls and ceilings.

So other than pipe installation cost, the rest of daikin is quoted at fair price?

I was told by other dealer selling both daikin and me that me latest r410 system could use back the existing r22pipes, however only me can do and daikin can't.

Have u ever heard of such thing?
There are a few thing to consider...

1. Are the old pipe correct size for the new system. If not, change to new pipe.

2. Are there any old R22 refrigerant oil traps in the old pipe? You will damage your new aircon if the old R22 refrigerant oil mixed into your new aircon running on R410 refrigerant.

3. Will Daikin VOID your warranty if their technician found out the new compressor is damage by old R22 oil because you never change the pipe.

This is a grey area for the reusing back of piping.

I feel that if correct installation steps are taken, the pipes can be reused if there are no leaking issues.

Need to vacuum the gas pipes before testing & commissioning which is an important step of the process.

Thanks for all your inputs.
Think I will stick to daikin r22 systems as I don't want to take the risk and complication of reusing the r22 pipes for a different refrigerant.

Been told that installing aircon on utility room is illegal by Courts. Is this true? Moving into a new flat, there's a aircon there already bit spoiled. Only want to install the air con unit, the compressor will be outside MBR.

Hi Masharno Wolfe,

Believe the utility room you are referring to is the hdb housing shelter?
If it is the case then yup it's illegal but since there is an existing aircon there then maybe u can try to nego with them I supposed.

See link below:

Hope the above info helps

The utility room is one added during an upgrading project, its like a tiny tiny bedroom with windows. Looking at the floorplan there aren't any thick black lines around the room.

In any case if end up not able to get the aircon unit on the wall, apparently casement units are okay so I'll have to go with that. Only concern is if its going to be noisy or not, seems like there's only one model of casement unit available (europace)

To kelvin_som,

I think no aircon can remove the smell from the room. (IMO)
The smell will just be thrown around the room.
U can try to input a fresh air fan to input some fresh air from external sources and a small vent for air to escape.
This might help.

Hello all,

My aircon has been dead over a decade, but finally decided to get a new system 3 inverter!

Problem is, I'm not sure which one to get, anyone has any good recommendation?

Plus the wiring in my house is really old, my HDB hasn't been renovated since we moved in 25years ago. The salesman at Gaincity was telling us if thats the case, MHI is definitely out because they require higher voltage or something.

What should I look out for when getting my inverter system 3? and price range any thing thing else that I have to add into the cost? I've been down to the showrooms, all the compressors look damn big! is there a size limit or something for HDB flats?

And usually how long does it take from purchasing the aircon to getting it installed? can they do it the same weekend?

Cheers!

So I just saw terumo's airconguru blogspot. Thanks for taking time to explain to us all the information we need there! was really helpful.

I saw that you recommended Daikin, Mitsubishi and Panasonic inverters. Fortunately, or unfortunately, those are also the 3 I am looking at and can't decide between.

What should I consider between the 3 to make my final decision? [Actually leaning more towards Daikin and Panasonic]
Are there any restrictions as I mentioned I live in a 25yr old 5-rm HDB that has never been renovated nor rewired.

I saw a lot of people recommend getting from gain city as they do very good installation. PC show... no promo la hor! hahahaha ;P
