If single phase power supply, is it good enough to run 3 air conditioning at the same time?
*
Yes.

I run 2 units 1hp and 1 unit 2hp every night. Try not to on every unit at the same time.

Wow, good to hear that. I forgot to get them to install 3 phase supply. Now the house already completed, and I feel it could be a hassle to install it. So plan to have single phase only.

BTW, for normal 1.0hp inverter air con (daikin and pana), the installation requirement is quite similar and simple right? Meaning I can purchase from online and get normal contractor to install it.
*
Yes

But if you ask the shop to package, it can sometime solve some headache esp problems during installation, they have to settle it.

Otherwise installer may say your hardware problem., then you have to call Pana or Daikin.

Just incase you get a lemon unit.

Hi want to ask how professional Aircon man check for leaks. My 1hp Aircon using new gas was installed using the 20 ur old concealed piping. Old York Aircon was also 1hp but using the old gas.

The new Aircon ran well for a year or so but suddenly not cold. One Aircon man came & check  indoor n outdoor unit joints with soapy water. Then top up gas n  say observe. Within few days, gas gone. Guy says concealed piping leaking must reinstall with new piping

Asked another Aircon man to have a look n he say do 3days pressure test on concealed piping. Also need to take indoor n outdoor units back to shop to check for leaks by "submerging in water"

Does that sound right? The piping pressur test sounds logical. But dunno about  checking for leaks by "submerging in water".  Also how much would this cost?

If I am you ...

Not necessary to do piping pressure test and submerging in water.

If space permit for a temporary piping connection through a window, get it done and test for few days. You see the result with your own eyes...whether is piping or hardware issue.

I did that when one of my outdoor unit having power issue. Did a temporary connection and confirmed result .. so did new wiring.

My landlord in apartment refused to install aircon in the living room which gets very hot due to facing setting sun. But has no objections if I'm to install it. Yeah he thinks I'll just leave It when I leave.

To not give him the pleasure, what 1.5HP aircon is easy to install and uninstall later on? I'm thinking of puttingbthe compressor on the balcony since its not used anyway..
*
Not that he like to refused ...just dont want to bother with who is responsible to maint and do major repair.

Installation and dismantling is same for any air cond. Buy those portable units if you want pack and go when tenancy expires.

How much is installation cost for 1 hp?
Getting quote for rm1250 for cheapest daikin 1hp including install. If buy from lazada is around rm900.
*
Is new installation or installer need to bring down the old unit ? If is the latter then fair price.

Otherwise, for new and std 10 ft piping

Single storey or condo 250

Double storey 280 to 300.

I wouldnt take the figures seriously. Different manufacturer different measurement methods....marketing/sales strategies.

"New' models, same components ... 'different specs' !

Regular maintenance will gives better efficiency than paper speccifications !

Is R410a piping can use for R32 aircond ?

Manufacturer/installer will require you to change.

You can continue to use but at your own risk relating to any warranty claim.

Hi,

Based on below chart, should i go for Panasonic brand?

No layman will be able to measure those specs after installation. Too many variables.

Buy which brand you 'trust'.

Do you by any chance know what are the procedures to find out if the process of vacuuming out the old oil was done properly?
*
The best the technician does is to connect one end of the coil to the high pressured gas tank and pushed out the oil few times.

Does that even clear out oil deposits?

Best effort.

Also depends on the length of your coil.

Hi all, my living room aircond (York 1.5hp / 7 years old) has been giving issues quite frequently lately. Planning to change to another model, any model to recommend? Leaning towards Panasonic for now.

Questions :

1.) Worth to go for inverter or non-inverter?

Usage for weekdays : 5 hours per day.
Usage for weekends : Sometime up to 8 hours per day.

2.) The living room has a high ceiling so is it better to go with a 2hp unit? Using online calculators shows roughly a 1.75hp estimate.

Thanks!
*
Pana.

Inverter

2 hp ... better have higher than lower. Less stress on ac to cool the place.

Thanks for the info. Any idea which looks better from these 2 Pana models? I can only see the Nanoe X as the main difference.

Guys,

Anyone can recommend me a contractor to install and supply aircond for whole bungalow, looking for quotation for total 11 unit ranging from 1 to 2 HP.

I need all the aircond pipe to be install and conceal inside wall/plaster ceiling while the construction is running instead of hack and patch later.

Many contractors very fussy. No location, no quotation.
