Just installed Panasonic Inverter 1.0HP air conditioner for my bedroom today. RM1400 inclusive installation (air cond unit, RM1200 plus installation charge of RM200 due to Inverter). Obviously I didn't bought the unit from Seng Heng which is really pricey (about RM1600++ inclusive installation). I bought the air conditioner from the shop that sells and specialize for the air conditioner unit only, not retail electrical chain stores. Can 'nego' some more
At first I was hunting for Daikin model, unfortunately they said that it might takes about TWO WEEKS to order from supplier
Daikin unit much more cheaper (less RM100 than Panasonic inverter - the reason why Daikin was way cheaper is due to R22 vs R401 refrigerant applied to the compressor) But I was really impatient to wait for two weeks, then I decided to just take Panasonic Inverter since they got ready stock for that unit.
- The indoor unit seems bigger, like 1.5HP air conditioner albeit it only 1.0HP when compared to my old cheapo Mistral air conditioner.
- Installation process was like a charm. Took about 40 minutes only to dismantle my old air conditioner and replaced it with a new one. Good workmanship and installer told me his 'ups and downs' experience dealing with air conditioner installation for the past 12 years. He seems really experienced and professional installer.
- Inverter unit will costs much more money to maintain. Conventional 1.0HP ~ 1.5HP air conditioner only costs RM80 for the brief maintenance, but Inverter will costs about RM130-RM150 for the maintenance (again, due to R22 vs R401A refrigerant). He said that maintenance need to be done like once a year. Depending on the usage styles. More frequent use, need to service every 6 months.
- According to the installer, there's 'nothing special' about inverter compressor. It just a normal compressor, but with build in 'intelligent' microcomputer board to control their behaviour for not to frequently 'on---off' like conventional air conditioner. Just hope that the microcomputer board will last longer since the costs to replace that tiny unit will be pricey.
- Installer also said that you can really saves using the inverter, but with longer usage like 5 hours++ every time you turned it on.
- Faster cooling as well as quiet compressor and indoor unit noise when compared to my old air conditioner as well as my neighbour compressor unit.
- Strong breeze from the indoor unit albeit fan settings was on medium-low, hence the reason why it cools my room faster. (temp settings: 25 degree celcius)
- I still didn't managed to understand well the functions of those-so-called 'ECONAVI'...
- Overall, for the time being I'm satisfied with my 'investment' with Inverter. I understand now the phrase ' you get what you pay' - RM700 Mistral vs RM1400 Panasonic Inverter. So much different between these two air conditioner. Perhaps it just less than a day.... I just crossed my fingers
Congrats.
It's a bit weird, in JB almost every shop has Daikin, or can get it within a few days. Only electric chain stores like Courts tend to not have the brand. Maybe it comes from Singapore, where the brand seems to be much more present (TV ads, billboards, ads on taxis, ...).
Yeah, I find my unit to be pretty quiet too. Especially compared to my old unit which was literally falling apart. Had to start the fan with a stick... trying to turn it until it runs.
EcoNavi... as far as I understood it, works by sensing if someone is in the room (similar to those lamps that can sense if someone is moving, and then turns on). If there is no one, for a while, it lets the aircon raise the temperature. So lets say you set it to 25°C. No one is in the room, after 30 minutes the setting gets changed to 27°C. Since rooms in Malaysia are not so well isolated, energy would be wasted by trying to keep the room at 25°C if it is not needed. Once someone enters the room, the temperature setting is lowered to 25°C again.

) 1 hp unit consumes around 30W... occasionally it rises to 300-400W. (30W is the fan working only... the old National unit used 40W when completely turned OFF). Though I have set the temperature to 28°C, so it doesn't actually have to cool that much, just enough to make me feel comfortable. My regular Sanyo fan uses 40W and is noisier... it also made me sick because it would be blowing onto my neck.
Hard to imagine that I lived in Finland for half a year.
