Old school piping save cost, it is thinner and smaller, compare to the new inverter piping.

Thanks for sharing... so old school pipe is cheaper because it is thinner but not smaller... right?

hmm... 10 years old, I will suggest to change new one. Household appliances use 10 years is like max life span...

Wow... now aircond also can buy online. But warranty may be a problem?

Sometimes labour and transportation charges are not inclusive in warranties.
Best is to call pensonic HQ and clarify with them

Opss... sorry for you... but how come you buy pensonic air-cond?
Usually pensonic goes for water kettle, toaster, mini-overn... they are not a reliable brand to begin with but they are cheaper and good for those not so expensive appliances ..

Guys... sorry if this is not related.
I heard of a air cond cleaning service which does not need to remove the indoor unit, the worker just tape the aircond area with plastic sheet and direct to pail. Then use high pressure streams to clean the fins.

Any body know the company name? Thanks.

Ya... something similar... but I don't want groupon... cause groupon for service is not good. Sometimes, the seller don't honour the deal.

Hi, any of you considering VRF or VRV type air cond in residential? Any information to share, is it more efficient and economical?

Oh... really expensive ah? Cause all the office is using... thought that it will be quite OK.
Besides, watch TV, generally US house most of them using such system as well.
Anyway... will survey more about the price and share here.
If any forumer got information can share as well

Already completed, now considering renovation planning phase
Generally required 10 to 12HP to cover the whole house. Around 8 units.
Let's say 1HP aircond is 1.5k, so should be about RM15k for all the aircond
Considering vrv because it will be great to install on the flat roof, so the house exterior can be nice
Research daikin have vrv system in this range
the problem is their indoor is customize, no idea how the process of mix and match

Now is to find if the price is OK

Just get more information about vrv system. You are partially right
Based on the information given, the price does not cost about a low spec myvi, maybe you are referring to commercial type vrv, for a residential type,
a 9 to 12HP is about 10k for the outdoor unit, maybe this is your so call mini vrv.
For my specification, the quotation runs to about RM50k, or maybe slightly less.
But compare to normal air cond, the cost will only run 20k. so vrv system is till 30k more expensive

The good thing about a vrv system is 1 compressor can drive up to 10 units or more, and the piping length can be very long. Good for condo with not much ledge to place aircond
The system get economical if you need to cool large area, 2HP and above is the place they shine, anything less is expensive.

of course, there is still alot of shop selling non inverter air cond
