To Leon,

If ur existing sys uses R22 but u r changing new pipes, no issue to change to R410.

Does ur Panasonic quote includes thicker (1/2) insulation or stainless steel bracket?

Lightbulb Need Advice

Hello, need advice. Here is the situation and plan, but not sure if it is sensible

a) Situation
I stay in a condo that comes with the 8 years old a/c non-inverter Daikin and concealed pipes. There are 2 condensers: System 3 to 3 bedrooms, System 2 to dinning. We usually only use the master bedroom (MBR) a/c about 6 hours week night and about 10 hours on weekends.
Recently got U0 error (means low refrigerant) ask Daikin come and check and only top up refrigerant (R22) and refused to check for gas leak. Say must do pressure test ($300) and can only tell if the leak is at condenser or pipe. Still got the U0 error but less frequent (need to reset a/c to start again in the middle of the night, yuck!)

b) Plan
Since only use MBR a/c, considering replacing the System 3 to System 1 (for MBR only) and change to inverter type to save electricity. Also need to change the pipe since the inverter type needs thicker copper and the existing one is possibly leaky.

Now, not sure if it is ok to leave the existing pipe and fancoil to the other bedrooms alone or need to take it out. Is it better to hack out the old pipe to replace with new pipe or run a new trunking? Any risk of changing system 3 to system 1?

Advice or comment is highly appreciated. Thanks!

To fbap9467,
If u r not using the 2 bedrooms, can leave it as it is and install a new sys 1 with pipings for the master room.

I guess daikin is better cause they only sell aircon and nothing else. But make sure u hoot the onewith latest gas. Cause the older type will be phased out.

I got a quote for Panasonic inverter type + 12 BTU+9BTU+9BTU for $3100, including removing old system and install new, + GST. Is this a good price?

He also quote similar setup but Daikin or Mitsubishi Electic but for $200 more. Does these two brand worth the extra $200?

Model CU-3S27KKZ(Panasonic), 3MKD75(Daikin and 3S28(ME)

Also, existing system uses R22. It is ok to switch to R410?

TIA
GC offer Panasonic system3 inverter at $2399 nett included 4years extended warranty for part n labour. Not latest model but 1 model older than current one. Sharing same outdoor unit. It's a good deal. Grab it b4 it's over.

Some people choose to service their aircon themselves.
Read this article before you consider if you should service your aircon yourself.

Anyone has experiences with MHI?
I got directed to MHI while looking for Starmex.
Seems that MHI is more power saving, cheaper and more feature.

I read that MHI's pretty good. But the power saving, according to the salesman, is calculated only via the power consumption of the compressor.

So if you use a weaker compressor, definitely the "annual cost" is lower since /hr is lower.

But using a stronger compressor might also mean that usage i.e. hr lower.

Both power consumption does not differ much, should be still acceptable.
Unless user has used two before to make a comparison.
I am interested in the ionizer function, can turn me into ion man =p
