I am buying new property (not yet start building) and it comes with built in piping for the airconds. As I was looking around, seems if using R22, R32 etc the piping requirements are different? The standard now would be R32 right? What should I check if I need to know if the built in is compatible with R32 aircond?

Upon reading further... the R32 is flammable compared to R410a?

I avoid installers that is assigned by the electrical shops. I look for installers from AC parts suppliers. A few of them were discovered this way. Similarly, I tend to distrust developer AC installers and wish they let me get my own installers to supply and install AC electrical, drainage and gas piping. Get the properly trained specialist to do what they do best.

Good piping use Inaba Denko Paircoil (JP). The other one it's Smartco Paircoil (KR). Each pipe is insulated individually (correct way) rather than 1 insulation over two pipes (wrong way). See here.

AC cost savings check the excel sheet with alexander3133 as he came up with the stats in this thread. He'll update it time to time.  Inveter already save from day 1. All boils down to how frequent in usage. The more it's used the faster the payback. If rarely used no point going inverter. If going 5 star, make sure you get good piping installed as described above.

Nice info! My developer included aircond infra for all the rooms, other than the pipe's brand which you mentioned is there specific dimensions I should be looking at? Both the electrical and aircond piping is done by two different subcons. I'll try to ask and upgrade if possible.

I have been using Panasonic inverters for wall mount, my new home came with cassette piping for the halls and master bed room. Among cassette, what are the recommended models for R32 inverters?

For inverters, I remember reading need 4 cores from indoor to outdoor unit. What about DB to indoor unit?

Need to clarify this, and make sure my developer gives me the right one 😅 else I need rewire again when house is done would be headache.

4 core in blue - Connect indoor to outdoor unit.( if not mistaken , non inverter also either 3 core or 4 core)

The one circle in yellow - AC Terminal, Some brand located at indoor and some located at outdoor

buy ur aircond first bro or let the aircond technician settle for u.

Ahh, cause developer provides the wiring for aircond (7 units). So since its still not yet wire up wanna make sure its done correctly. Don't wanna hack after the home is completed.

Current home uses Panasonic inverters, was considering Daikin for my new home until I saw this post 😅 Guess I should stick back to Panasonic for my wall mounts.

For cassette mount which are the better choices? Mitsubishi? Panasonic? Daikin?

Developer provided 4 cassette points (one which I converted to wall mount cause that ceiling is about 16’ high 😆, show house 2 HP can’t even feel anything). Other 3 is at master bed room, living hall have two, one in front and another at the back “dining area”.

Any Mitsubishi JP series (Mr Slim) users here? Do you appreciate having the ability to access the rollers directly?

I currently stay by the main road, using Panasonic inverter which uhh every 3-4 months I need to call people to come clean mainly cause the blower is clogged up.

Am surveying if I should stick to Panasonic or maybe move to Mitsubishi for my new home (mixture of wall and cassette wiring/piping provided by developer).

Also the Daikin FTKF sells their so called easy removable drain pan, I guess if able to remove that I can also access the rollers better. Any thoughts?

the removable blower would be a great help when cleaning. i would definitely go it. the Daikin removable drain pan is a plus as well. but do note that most, (if not all) of Panasonic's new R32 models came with blue fin technology as standard. this will significantly increase the durability of your unit by 3 times compared to normal aluminums fins.
*
I tried to request my seller to quote for the Mitsubishi Mr Slim but was informed they don't have stock and it is discontinued (no wonder I can't find Mr Slim from the website, only from google search).

I'm a Panasonic user for some years, but now trying to explore for options for my new home. Leaning towards Daikin now with the easy removal drain pan biggrin.gif. But well noted on the blue fin... so far my previous Panasonics holding strong la, and they aren't blue fin models too.

now sure why  you put  drain pan  as a  must want factor  when buy a AC .
its so easy to wipe clean  the drain pan  ...  and should be fine for like 2 -3  years.

the fan blower is easy  to clean   without need to take out  with the proper  cleaning tool s. DIY .


more important  are    the STAR rating , EER specs,    cost of operation ,  and  good features  like ion air , Follow me, iFeel   etc. 

if money is not a problem  go for the pana inverters. 
pana inverters  have about a  5 -10%  power cost saving over  sharp, hitachi   for the specs  i see.  assuming  operating setting are same same.

What is this proper cleaning tools for the blowers? Now I'm getting interested.

I have been using Panasonic inverters at my home for quite sometime now (CS-S10PKH mostly these 1hp units but I always can't figure out how to remove the vanes ._.)... these nanoe or that moveable vane and flaps is what I already have been using but then seldom use the econavi also la. My problem is always sigh, the blowers gets clogged up and wind flow becomes really crappy.

Jelly... jammed my entire drain pan. That purple stain, I’m suspecting the guy who serviced might have used iron remover 😓

For me I still stick to manual vacuum (+ long bristle brush to loosen) clean (for fixed IDU fins) and whatever is removable (filter) can wash lah. Coz some of the 3rd party service wash using harsh chemical that eats up (react with) the fins.

I normally do that, but hard to access the roller mainly also the vertical vane kacau. This round really just yolo and pull it all out.

i wonder where the jelly  come from  ...  nod.gif
normal is just clear water.

is this aircond near the kitchen ??

6  months and your  fan so  clog up...  again am surprise...  your area very dusty ??
mine still clean after 2 years. 

i suggest you use  daiso  AC  filter .  to get cleaner air into the system .

So far based on my experience, always when jam up is the jelly... only this time I was able to do it myself. Normally pay those aircond service man RM80 per unit. I live by the main road... landed house. So dust level is crazy, imagine my car park outside after 1-2 days also got dust will accumulate. This room has a Panasonic filter 40m3 capacity model running 24/7 also that dirty.

You using the Daiso aircond filter? I'm gonna give that a go, thanks for the suggestion! with this maybe don't need to clean as frequent. This unit is upstairs, inside room which is quite far from the kitchen.

As I know the jelly forms inside the drain pipe.. how come the jelly comes from the fins..anti gravity mode flubber kah? laugh.gif

That section of the coils are very near to the drain pipe... 2 potentials are when I removed the drain pan I accidentally soaked the coils in, or the jelly is just too thick until go on the coils. (gonna check on the other units during weekend biggrin.gif.)

First time remove laugh.gif , wife kept ringing my head and didn't want to hire these professionals due to COVID-19 sweat.gif spend 3 hours, watching video as I figure out LOL. But next unit I were to service will be much faster and more efficient.

Just brought a Mitsubishi JP serius 1.5hp aircon. 

To replace the old Panasonic inverter. Aircon still running fine. Just aging and less cool.

JP series have the easy cleaning and dual coating. Easy clean help to easy get into the blower to clean. No need to take out the cover.

While dual coating reduce the dust stick to the coil and blower. J

JP series is the Mr.Slim right, which the R32 inverter is phased out unfortunately. So I went with Panasonic for my wall mounts for my new home since I got the hang of it on how to service them now.

R410A will phase out 2025

R32 is the latest replacement.

No Aircon have the easy clean accept Mitsubishi.

Cause I clean Panasonic aircon for over 20yrs. And I have another Mitsubishi aircon to compare.

But not all Mitsubishi aircon have easy clean.

From what I surveyed before, Mitsubishi JP series are the R32 inverter with Easy Clean, but JP series has been discontinued and replaced with JS (I think...) series which is another R32 inverted but without the Easy Clean feature unfortunately... so yeah will just stick to Panasonic for the wall mounts.

I think only the non inverter JR are the ones with easy clean feature.

Mitsu models the current basic inverter is now JS series.
There is a difference in the design - some model is designed to fight on entry level price point - some model maximise everything for you - not all 1hp is built the same, as such even the BTU capacity design differs.
The 9000 btu type doesn't cool as well as a 9700 btu nominal.

This is why if the 1.5hp is quite cheap (in the case where the basic 1.0 hp is on the smaller side 9000, and 1.5hp model is reasonably priced a.k.a. similar as other brands' 1.0hp) for a larger room to be cooled, can always consider taking the 1.5hp to avoid disappointment. From my experience my higher btu 1.5hp (12640 nominal, turbo upto 14330) is perfect for my living room whereas some neighbours in the same project were complaining their 1.5hp (on the lower end of btu performance say turbo up to 9895) not good enough and advised me to use a 2hp instead.
Hence newer isn't always better if both the newer and older are also R32 inverter.

Out of current series the JS one (basic) doesn't have Easy Clean. Only GR and higher premium series got.
However, JP series is still available on shopee and other online stores by electrical shops.

These specs are from Mitsu website.. I have no idea why their basic 1hp consumes more running amps than the same series' 1.5hp  rclxub.gif  rclxub.gif

Bro, thanks for the input! For some reason, all my Mitsubishi quotes I gotten was JP or JS, none gave me GR so I assumed all the R32 inverters no longer have Easy Clean... even my friend who works at Mitsubishi Malaysia also just told me JP discontinued, replaced by JS walao dry.gif. The one that still has JP series, only sells Mitsubishi units... I wanted the Daikin cassette so have to take from another shop but that one doesn't have JP anymore.

Will check the comparison between GR and Panasonic XPU series, haven't finalized my airconds... mixture of wall mounts and cassette to install.

JP, JS, GR have easy clean. Only JR and top model LN don't have.

GR still available online Shopee. Mitsubishi bring in batch. After finish, not import anymore. So some seller still have stock till finish.

In my case, the shop no more stock and check the distributor which no more bring in.

So I choose JP instead JS. As the JP have the dual barrier coating feature which less dust stick to the coil and the rotor. Aka, easy clean and less cleaning.
*
I see, so basically GR model would have the same functions as per the outgoing JP. I went to check at shopee for 1.5 GR and 1.5 JP... alamak the price up quite a bit tsk. I will probably stick to Panasonic 1.5 XPU instead.

Hi everyone, need some help! I am deciding between 2 brands for a medium sized bedroom, approx. 150 sq ft, 10 feet height.

Daikin 1.5HP Inverter FTKF
https://www.daikin.com.my/daikin_products/ftkf-series-r32/

Panasonic 1.5HP Inverter X-Deluxe
https://www.panasonic.com/my/consumer/air-s...xpu13wkh-1.html

Which brand is colder? Is it a big or small difference?
*
I considered between this 2 units as well, basically I lean towards Panasonic. Spec wise the Panasonic is more efficient... and the panasonic has adjustable vertical vanes while the Daikin don't have it... The interesting about the Daikin is the wifi control and also the removable drain pan... (but I can't find videos online on how easy to remove the drain pan for cleaning la... those jelly things that causes the water outlet to stuck).

Oh right, another thing is... Panasonic comes with the nanoe tech.. Daikin I think only the smarto has it (which costs a bomb).
