Hi guys,
Just want to have some opinion..
I have 6 aircond (2HP/1.5HP/1HP) plan to pasang for new house but i am not sure how should i choose the brand.. Daikin/Mitsubishi/Midea/Panasonic/Samsung

can give some suggestions?
*
If you are satisfied with your existing brand, buy the same ...just 1 brand for the entire house.

Mix brands are not advisable unless you want to deal with different problems when it arises.

Try manual adjustment to 'lossen' it. Then reset

Hmm, manual adjustment doesn’t seem to make it move(upon reset), even after disassembly to the bare motor itself sweat.gif

Can feel the bare motor vibrating though

Check whether the head connected to the motor is crack. It may prevent proper grip to move.

One of my unit flap also cannot open close and also swing up down due to the same problem. So I inserted a board to place it in a permanent position.

If is under warranty, call cs. Not sure the crack part is covered thou.

Apparently nope, no cracks upon visual inspection. The unit is now 6 years old roughly sweat.gif

Seeing the replacement motor is selling on Shopee for roughly rm50 can seem to figure out a way to unplug the motor

If the motor is vibrating or rotating, I doubt is the motor. It could be wear and tear of the plastic flaps or something or dirt accumulated to prevent it from moving.

Anyway I am just guessing as I havent seen it.

Yup the motor seems pretty dirty coated with black dirt( didn't take a picture while disassembling sweat.gif)

hmm.gif , the swing motor cable is behind where the main AC/compressor connection point?

Sounds like something that a technician would do rclxub.gif

For the time being time, I’ll just use my hand to operate it like a basic AC


Thanks for your advice though

It's almost time to change my ~19 years AC.
It's not as cold even I set it to 17°.
Recently DIY cleaning the IDU also did not help.
After scrolling thru, I gathered that -
1) Higher BTU
2) Higher Efficiency (CSPF)
3) Higher Warranty
4)
How to calculate the btu needed, as I've checked with a few websites from 8000, 9000 some advise to add extra 10%-20% btu, Pana recommended 1.5hp and Daikin website recommended 15,600 btu.
Room size- 15'W x 12'D x 10'H. So what will I actually need 1, 1.5, or even 2.0 hp?
Normally we set the a/c temp at ~19°-20° with timer for 4hrs. Do I need an inverter type for temperature of ~19°?

Reading thru most people recommend to set higher than 24° for a better energy saving. We do prefer a colder environment like ~19°-20°.

Any data to justify on the inverter ac vs non inverter ac for 1hp, as I'm thinking (might stretch a little for 1.0hp) by buying a higher/colder btu, the room temperature will drop to 19° faster then it will stable at the set temperature with better energy saving compare with a lower or lesser btu that will take longer time to reach the 19°.

So I need a lowest btu range to a higher boost range btu with Good/Excellent CSPF & EER. Right?

Hitachi RAS-VX10CJ/RAC-VX10CJ OK or ?

Hi, my aircond switch broken, saw got 20a, 45a, etc..
not sure which type i should buy..

my air cond model is Panasonic 1.0HP R32 CS-XPU10WKH-1
https://www.panasonic.com/my/consumer/air-s...xpu10wkh-1.html

1hp is around 6-7A current so a regular 20A water heater switch will be fine. Get MK or Hager.

Longer warranty, Higher btu, higher CSPF / star rating, sushi brand, NO KIMCHI, NO specific brand with Heavy Industries in the name. The regular Mitsu MSY-xxx P/N models are OK.
There are economy series and standard series. Usually the lousier ones get 4 star ST and the better ones are designed for 5 star ST.

VX10CJ is good for a 1hp inverter spec, but since you are using it at "freezer temp" of 19C it may take at least few hrs to even get close to 19C. = this 19C target is like driving a kancil full throttle all the time..
hence whilst 4.5m x 3.5m Room size is considered small enough that a good 1hp inverter is adequate for temps of 25-27C (I'm skinny so cannot tahan cold),
as you prefer target 19C better take a 1.5hp so it won't struggle. still possible to buy the RAS-SX13CJ. - https://www.lazada.com.my/products/hitachi-...1189036296.html

Guys my Samsung WindFree 1.0HP is having auto shut off issue after 2 mins running, with error code flashing “C1” then became “01”. I’ve tried to run auto clean which also failed halfway through (that’s what the C1 usually mean). Anyone has ideas?

Hi Sifus,

im looking to buy a few airconds for my home. A few 1.5hp and 2.0hp and 1 3.0hp

I've been searching online and realised there are 2 refrigerants to choose from; R32 vs R410A.

What would you recommend as I want it to be environmentally friendly ie. less toxic.

I'm looking for the inverter models to reduce electricity cost as well.

So far looking at Panasonic models.

TIA.

R410A refrigerant models have been phased out, unless it is old stock. Most manufacturers are going towards R32 now. If you looking at Panasonic inverters,

There is the X Deluxe Inverters, Deluxe Inverters and the Standard Inverters. End of the day, it is what features do you need.

Hi all notworthy.gif My air cond installer quoted RM3.9k for *6unit air cond (conceal + installation job) for my house. Is the price reasonable?

*1unit is back to back and another 5unit involve conceal job w/ average 10-15feet per unit. He is using 0.71mm copper thickness, i saw ceo684 posted it before. So i assume the thickness is fine.

Much appreciated if someone can advise before confirming with the installer.

There are plenty details in the net regarding the 2 refrigerants, invertor and non. Take your time to read and undetstand b4 committing to a purchase.

To add ... if your usage is for long hours, buy an invertor, otherwise a non will do. So you have to decide which room unit is invertor and non. But if you have the budget, then go for all invertor.

Pana is ok .... others no comment.

For split unit
Pana X-Deluxe, Daikin FTKU, Hitachi, Mitsu Mr Slim (MSY P/N, not the MHI SRK), Gree Lomo Queen Inverter generally OK. Compare BTU spec for each class (1.5 to 1.5) and warranty.

For cassette or mini cassette
Choices more limited - Pana. Daikin. Mitsu. Acson.

You can consider multi split IF you are not using ALL the unit at the same time. Multisplit is somewhat more economical especially when you are speccing higher hp aircon.

R410 may be older model but sometimes much much cheaper for the bigger unit 2hp and above cassette, can be 1k cheaper (or more) vs the R32; it may be better CAPEX to get a cheaper R410 INV than a new R32 NON, for lower OPEX.

Not knowing how big ur units are
250-350 per unit give or take 1500-2100 for basic installation.
0.71mm copper is good, preferably acson/daikin pancake
Make sure IDU-ODU is 4-wire. The extra one for signal, use thin wire 1.5mm also nvm. 4 wire (LNE+signal) for safety. Thin wire dont cost much to add on, but its a PITA once u installed as u can't just add on easily.

Rest is hacking cost and concealment.

Inverter for bigger units should save power.
Also depending on usage pattern. Keep at 25-27C very power saving. Running it like freezer 16C best inverter also useless for power saving. laugh.gif

Build quality, star rating, cooling capacity, extra features.
Not all AC are created equal.

Some are built for ticking the box "got aircond" at cheapest pricepoint
Some are better built.

Its like buying a car kosong spec 2.0L vs high spec 2.0L.
