yeaa!! i was actually considering the same thing as i remembered my parents house using a normal plug to connect to the aircond, but was told by a few electrician that i have to pull the wire from the mainbox which really confused me. Using your suggestion would definitely save me a lot of time and money.

So it is possible to extend the wire from my typical plugs as in the diagram below? there is a power plug right below those switches

There is not much an issue, my rear bedroom forgot to install power also and the Aircon man tap from the original socket for support 2x1.5hp also don't have much issue, becoz bedroom socket really never used much and sharing for fridge or water heater that is bigger issue of this, if you still worried then go for inverter aircond the original input watts very minimum, unlike non inverter for each secs used the same input watts for supply compressor runs.

Inverter got part loan meant the energy will reduce from 100% to 50% after temp. are reached.

You need to check and calculate properly the total load of the wire (if you decided to pull from one of plug point) that do not exceed the maximum ability of the wire.

This is ill advice.

Inverter at full blown (when start operate time), it consume the same amount with non-inverter, just ability to run at partial load in operation afterwards (when the room is cool enough), that result in saving in electricity and draw less current.

Inverter is not using less current by default.
At 100% running, inverter still consume high current.

Despite many time explanation, seems like still not getting the right understanding of inverter.

1) possible
2) Plaster ceiling can be "re-patched" after the job done, not much an issue.
3) No contract will want/dare to drill through a beam, so you need to round it.

You need to check properly in term of load capability of wire and your total loop of the wire, from the point that wish to pull/loop for the air-cond if decided not using directly from the DB.

As even you see is just a plug point, sometimes there is plenty of loop sharing the same supply behind that you do not see.

And also, the rating of the wire pulled original that can carry how much load (A).

Easy way to check, is off the Circuit breaker in the DB, see how many point do not have current, then already know how many loop has been applied on the single pull of wire.

Inverter standard preset was 25C vs non inverter 23C from the starting power draw was lesser.

Don't forget inverter is variable BTU and full detect on actual temperatures indoor & outdoor also variable speed and runs.

With compare to non inverter high power input from maximun draw..

So in day time was runing higher speed or low speed as what you set on... From non inverter you can't set to 27C these was compressor stop runs.

Also inverter starting was runing slow speed to maximum JET speed vs non inverter full load power.

Both is still reach at maximum watt of running when require.

If you see aztechx where he place the aircon. It is in the hall + dinning area. That probably require 2HP and more. Either he install underpower 1.5Hp or correct power of 2HP, both are running at high watt. (1 longer time with less watt and 1 higher watt with short time.) Is it better for him to have separate wiring ?

1. anywhere is possible.
2. there will be damage if they hack there, else, nothing will happen.
3. not advisable as far as possible.
4. depending on the length, works to do the job.

Anyway, your plaster ceiling are really good, on heat retention.

I shake head with the reply.

In term of wire consideration, you considered the maximum current draw by the appliances, as it is a very dangerous to let cable to run over its rated capacity whereby wire can get hot and burn.

Please don't spread false understanding that inverter draw less current hence can loop the wire easily as compared to non-inverter. It is an ill and dangerous advice which could cost life!

They both draw the same amount of current at full blown.

Panasonic non-inverter 1 HP CU-C9QKH
https://www.panasonic.com/my/consumer/home-...r/cs-c9qkh.html
Running current = 3.6A
Powerinput = 790W

Panasonic inverter 1HP (CU-S10PKH) https://www.panasonic.com/my/consumer/home-.../cs-s10pkh.html
Running current = 3.6A
Power input = 225-920W

York YWM10L 1HP non inverter
Total current 4.38A

York Y5WMY10JF 1HP inverter http://www.scribd.com/doc/142020182/York-Inverter-Catalog

Total current 1.63~5.06A

The inverter at full blown can draw more than non-inverter.
As you need AC need to convert to DC for inverter motor to run, there may be conversion loss as well in between.

Ok, maybe nowadays for most developer has wiring cutting cost and used china made... Then have no choice died died then to be re-wiring and end story

being offered Pana and Daikin by contractor, but I am keen on ME. may need to source aircon myself. any shop with good price in klang? else which brand should I opt? thks

I plan to install 3 airconds for 3 rooms. 2 rooms with each size about 11" x 20" and living room about 22" x 30"?

Any brand and horse power recommendation ?

1.5hp for 11x20" and living go for 18k or 22k btu is a minimum required

any brand? inverter or not? prefer save electricity

ME inverter and the rest not sure.

ok ive decided to rewire the aircond from the db box for my hall aircond. However i was quoted below from my usual contractor and was wondering if its a bit on the high side

Copper Pipe for
Aircond 1 - Hall unit as shown above
Aircond 2 - master bedroom unit with wire already jutting out of wall (i assume copper wire is not needed here?)
he quoted me RM800 for copper wire (35 ft)

Aircond point (what is this?)
RM150

was wondering if its reasonable. basically the cost above includes the wiring an repatching for the fresh new wire frmo db box. since hes quotation is based on 'agak agak' very hard to get itemized bill.

okie thanks! actually only one of my bed room is frequently using air cond. the other one is more like guest room and we don't usually switch on air cond in living room as well unless got big crowd. so i assume ME inverter for the frequently used one and how about the bedroom + livingroom?

Aircon can be used for longer time, just get a better one, cause you may not change it often.

Like no used Aircon can be power turn it off also.
Everything your pocket money just pay for 1 time only.

Next time got GST of the price lagi higher.

Recommend you ME is easier access to blower and clean out by own.
Also quiet don't have wave noise.
Cooling also quiet good.

hehe..you see the pictures posted on this forum..
i see plenty of the contractors drill through the beam so the wire can go through
