Pana inverter... 1.75hp.. up to 1700BTU..
No, for bedroom..

About 500sq. ft.

Partition? No no...

Guys, need help. My aircond living room brand Electrolux never do service maintenance after few years.

Even after I clean the filter, the cold is not it used to be. Do I need to add some gas? Or what?

Can recommend any technian? Subang Jaya area.

Ask the technician. What causes the leakage. They only have 2 types of water leakage.

1. Drain pipe clogged. This will leak like water fall.
2. Condensation of the piping. This probably like droplets.
3. Poor concealed drain pipe job (no level) this will easily clogged tour drain pipe if your room is extremely dusty.

If your drain pipe never install properly this will get high chance of leakage + dusty.

Condensation is caused by FCU poor air flow. Suggest to service.

Drain pipe flush down with chemical. Can buy at any DIY shop. Usually they don't carry these stuff. Get for them.
And. Never buy those can spray to spray your coil. It only get worst when the contamination flow into your drain pipe. It will stick when it's dry. I personal don't recommend this. If the can can works like a magic spray. Ac shop no need to do any servicing. Spend a little money to do the service.

Does it stop leaking for a while after the outlets is cleaned?

One of my AC units does the same thing - once every few months it'll start leaking. Go on a ladder, take off the front and lift up the unit then blow through the pipe (I know, a bit disgusting!) and it'll be fine again for a few months.

So this is the design fault? Which mean even if I change a new indoor unit it may happen again....?

I'm guessing mine has a bend in it somewhere which causes it to get clogged - all other 4 ACs I have don't have this leaking issue - drain pipe hasn't been cleaned in the last 4 years on those and no leak at all.

Hi all.

I have one carrier aircon which brought on last year (nov).
The problem arise when the unit is turn on for more than 4 hours, the aircon sometimes wont blow cool air. Checked with the compressor, the compressor stop but after few minute it began to start and the cool air being to blow out.
But the problem is the compressor stop too frequent and although I set 17, the room not soo cool as compare to other aircon.

Already call carrier service and the technician already came 2 times and the refuse to repair or change since during they visit, the aircon works well and no problem arise.

What should I do now?
*sorry for bad english*

already clean. During the technician visit also he said that no dirt on the coil. But during his visit the aircon just turn on and still cool.

after several hour and the aircon become less  cool

Thinking which to buy.... please guide
Panasonic PV18SKH
Mitsubishi HK17VA
Harvey norman salesman told me mitsubishi can open up for washing.

What brand/model would you recommend for 2HP?

greetings fellow forumers,

I planned to install an aircond in my living hall. Need recommendation on:

- HP power
- inverter or non-inverter
- should I consider centralized-type?
- brand (got 2 room airconds now mitsubishi and samsung and mitsubishi is the best)
- roughly the estimated additional bills for a month

Here are the details:

- it will cover my living hall until my kitchen. It an open style house so nothing I can do about it. Size about 45'x18' I think (1 big tile is about 2 feet right?)
- there also stairs to 2nd floor.
- weekdays will use maybe 6pm-9pm. Weekends maybe twice 12pm-3pm and 6pm-9pm
- I got a very high ceiling living hall so the volume is more i guess.
- Windows not tinted.
Many thanks!

I always off the main switch when not using the aircond. Now my PCB spoilt in last year and this year, could it cause by too much on/off main switch and the so called hit by high wattage ? 

Will lots of bird shit spoilt the outdoor unit?

A contractor quoted me this:

1) upah pasang 1.5hp inverter = rm 481.00 normal 10 kaki paip. Jika  tambah paip 1kaki rm 35.00
Jika paip kena tanam dlm simen harga lain.

2) upah pasang 1.5hp aircond biasa.
rm 364.00 normal 10 kaki. Tambahan paip 1 kaki rm25.00.
kalau paip tanam dlm simen harga lain.

3) upah pasang 1 hp aircond biasa back to back 10 kaki rm 312.00
tambah paip rm 25.00
kalau paip tanam dlm simen harga lain.

Is this right? Seems so expensive.

anybody here can advice me how much tnb charge per hour use of 2hp aircon? thanks

thanks Supersound. So 2 units per hour is how much RM?

I help you on this. Using my AC mode clamp meter, for 1 HP is about 3.3A, so roughly 2HP is about 6.6A for the current consumption. let say the incoming voltage is 230V so you have

Power (W) = 230*6.6 = 1518 or 1.518 kW.

Again this is rough calculation but the accuracy is there. This power only achieve during the compressor kicks in, lowest temp (16C) and high speed blower. Therefore, for first 200 unit block consumption it would be

1.518*RM 0.218kwh = RM 0.33 per hour
for Panasonic Inverter 1.0HP  (5 star rating by the Energy Commision) with Econavi mode from my reading it was

Settings => 28 C , full speed blower , econavi ON
Current consumption the first 1-2 hours => 2.7-3.5 A (621 - 805 W)
After 2 hours till to the 12 hours => 1.0 - 1.2 A (230-276W) about 6 pieces of normal flouresent lamp

You are the one that misleading,

From your link non-inverter is 11.1 Btuh/W (9,210Btuh/830W). Means 1 W of electricity removed 11.1 Btuh of heat.
Inverter is 12.57 Btuh/W (9,550Btuh/760W). Means 1 W of electricity remove 12.57 Btuh of heat.

Do the maths. I believe I have proof you wrong before and you still come here to mislead people.

Please check back our conversation on 23rd Sep 2015 as shown below.

Side track a bit, just realised that Urusara 7 1 hp AC EER is 19.53 (8400Btuh/430W)

"As I said before, inverter only do wonders when it starts to ramp down its output, else it will be worst."
Your links already proof you wrong, at max load no need to ramp down, inverter still have better EER. means still more efficient at any circumstances (ramp down or not) if compare to non-inverter.

"But I'm sure you will deny this, go and buy yesterday's SIichew on the first 10 pages already prove that inverter are not god in power savings."
See, your links proof you wrong. Now you try to spin to yesterday Sinchew (luckily not last year one). I seldom read newspaper, but my house do order Sin Chew. Let me go back and read it. Again what I suspect is they did't proof anything, just someone who act expert and talk cock like you.

"You may able to twist in the forum, but you can't twist what in reality."
You are the one who post those links which generate by manufacturer's expert, but they backfired. Now you spin to yesterday newspaper. You call newspaper is reality? Now I know why Utusan still haven't close shop.

BTW, asking people to read this, read that to justify your non sense is always your style. This time you are smart, no more link so I can't shoot you on the spot. Not like last year, you post a link of hundreds pages technical manual to ask people read carefully and still end up nothing. Again next time ask people to read encyclopedia. (Those interested about how supersound spin previously, can start reading from page 57~61).
