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.

ur developer electrical is talking about the yellow . DB to power up ur aircond unit

u are talking about the blue.

Hope this clarify u.

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.

If Panasonic consider noisy then what is Daikin then? Lol.

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.

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.

ok will update  in a few days  .. as need time to prepare . 

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 wonder where the jelly  come from  ... 
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 .

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

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

R22 is phase out.

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.

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   

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.

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