How's the Hitachi brand in A/C? Is it reliable?

4yrs old panasonic 1.5hp inverter used to be cold at 23 - 24c. Initially, weak airflow, start dripping, not cold then called for servicing before Raya. Technician said r410a refrigerant drop 1 bar but still enough so no topup is required. Now airflow is strong but why run more than 2hours at 16c still cant feel the cold, due to refrigerant ?

Mitsubishi or LG aircon? Someone help

I have read up a lot about Mitsubishi aircon reviewand lg aircon review but I still can't decide

planning on getting 1.5hp inverter air cond.
now looking at these 2 model:

1.  haier hsu-12vnr18r () - RM1699 w installation
2. daikin (ftkf35av1m) - Rm1879 w installation

from the spec the only different I can conclude:

1. 10+3 warranty, bit higher cfm, cheaper
2. 5+2 (promo) warranty, reliable brand, econo mode

any thoughts on these two? or if there other better model do suggest. TQ

Airflow is strong now and compressor is running at full load amp. Just wondering could it be low refrigerant, even short of 1 bar. 

can i retrieve the error code even though it is still operating normally.
No, last time technician didnt wash the outdoor fins as still clean according to him.

Hmm, sorry but I'm confused. If we set the temp to low setting like 18-20C, the compressor will run all the time, which leads to high electricity bill and also compressor failure (maybe?).

But if we set to 23-24C, the compressor will turn on and off depending on the room temperature achieved. This is the 'normal' way that an a/c should run and will give some electricity bill saving, right? But, this will lead to capacitor failure?

1 of my FTV28P giving problem on Outdoor Unit. Very loud reciprocating noise. I not sure what kind of failing sound. It just 1 year 9 month old. Proper usage is around 1 year 2 month only.

If you use inverter, the compressor speed will go down to maintain the room temprature. The lower the compressor speed the lower the power consumption (less than 1 amp).
If you use non inverter, the compressor is turned ON and OFF which compressor capacitor will work hard to kickstart the compressor, doing so will pull your electricity higher.
Many people are mistaken with the assumption that inverter saves energy if you operate more than 8 hours.
It starts saving from the moment you turn ON your aircond provided you have sized the unit correctly.
It is your choice anyway. ROI is quick with the inverter. I know because I have 6 Panasonic inverter.

as far as i know...the formula is:

size of the room x 60

so 230 x 60 = 13800btu which explains why i put 2hp

When purchasing inverter, you must undertand there will be 2 control boards, one at the indoor and another at the outdoor. Once any of it is broken the cost to repair can be very high and the spare part may be not available.

So my sincere advice is to go for the brand with the reputation. Do not choose manufacturers from China or Thailand as the spare part will be scarce.

Go for the most trusted brand Panasonic as they are made in Malaysia. The spare parts are plenty.

Do not buy cheaper goods which you will regret later for not having after sales supports (spare parts).

Having the sales/service office does not carry any weight if they do not keep sufficient spare parts for long term.
(Hint for you: volkswagen malaysia).

The difference from one brand to another is very much related to their internal policy. 
A simple problem can give you an headache :- a rubber bushing that wont last more than 3 years will cause aircond compressor to vibrate and cause annoying sound.
After 1 year warranty it is you cost.
Does the manufacturer’s policy ensure the part can last 10 years? The same thing with other parts like plastic grilles. Can it last without breaking up (ie during servicing)?
The same thing with the electro-mechanical. Can it withstand the time?
Each manufacturer has its own standard and for that reason you won’t find commonity in parts or materials used.

Hi all sifu,

My Panasonic non-inverter aircond is from 10+ years ago and is due to change. Below are some of the units recommended by salesmen and I'm wondering if anyone can tell me which is good or out of the list below. I'm not an aircond expert per say and I'm having difficulties to choose a good 1hp inverter unit

It is effective to reduce the vibrating sound and helps to isolate the sound from getting transferred to the indoor.

Guys,

Plan to buy Panasonic CS-XU18VKH from Senheng.

RM3629 (1 year general + 1 Senheng warranty). Need to add RM259 if want additional 3 years warranty. Total: 5 years warranty.

1. Is the price okay?
2. Is Nanoe-X and Nanoe-G really effective?
3. Can i remain on 1phase DB for 4 inverter AC(2hp x 1; 1hp x 3)?

Thanks.

What's the average Kwh for 7-8 hours use on 1.5hp and 1hp inverter?
