PJUSA, I use a 1.5HP Samsung triangle. While they are nice to use, they are not easy to clean the way you mentoned. The louvre has horizontal grille intersprsed at a every fixed width which blocks any vacuum crevice tool from reaching the blower. An AC installer/maintenance guy needs to degas, take the unit apart, clean and reinstall and then re-gas. This is not my opinion. It' was told to me by the guy who came over to look at a water leak issue. I have called Samsung and asked for a maintenance document for cleaning cos their manuals are not helpful in that respect. Mine is due for cleaning after 9 months as the blowers are acummulating dust and it's kinda making a very low almost creaking sound but it's barely audible. Unless the ARnnJVFSB models have improved this aspect, try getting something else. Also, their service turnaround sucks as they rely on a pool of AC technician which are not in-house but rather contracted according to locality. Good product (well it cools as it should) but a bit user-unfriendly maintenance-oriented engineering (cleaning the blower) vs the easy clean model such as Mitsubishi Electric.

Unless a deep reach, small and narrow crevice tool are made, then this aspect of cleaning is confined to qualified technician.

[Edit: Additional info: The manuals do state where the clips are but these are for securing the whole indoor unit to the Alu mounting frame. There are various spots where inner clips are located which can be easily dislodged. BUT there are hidden screws in the front along the "beam" between the filter and louvre. These may need some sort of torque screw to remove. This is perhaps one of the many that hampers removal for risk of breaking the outer chassis at this location. I'm unsure where else the other clips and screws are. Hence a field service manual would help show where these are located. Even if a service technician does what's recommended, unless guided by a field service manual as to how to disassemble the indoor unit chassis from the rest of the unit, how is the technician going to clean the blower unimpeded by the horizontal grill? And Samsung sent technicians mention that they don't provide cleaning asking our own to do so. Kinda like catch 22.]

Thanks your value info of samsung triangle design.

That's a main concern for when buying a product and made from mfg design for user friendly as a cleaning with maintenance to be much easier for future used.

MHI, Toshiba under China, Fujitsu or Daikin Thailand to be the same, not easy for remove out the fan blower as well, unless to be fully overhaul and remove out a whole fan coil unit.

Daikin GA is under York inverter previously design there's was a better a bit, cause still removable fan blower for few screws only, just not really easy for clean out drain pan as well.. Due to drain pan attached together with the whole chassis, once a water leakage may remove a whole FCU for a overhaul will do.

Pana design still ok and easier for remove a parts of fan louvre & fan blower, if there was 3D airflow design will be more difficult part.

Cheap like China Aircon brand also were difficult for maintenance too, cause I had Gree Aircon in hometown.

Actually LG recent design was a better for maintenance than samsung triagle, if wanna consider for Korean brand then go for LG you never get wrong.

Hitachi seem like better brand and selling much expansive, but I had found it is the worst Aircon and also parts selling expansive but made in China too, again the maintenance also were difficult too, even remove out fan blower or cleaning interior parts.

So far so good a better and user friendly still Mitsubishi electric like no others.. Lol

thanks super valuable information. i will skip samsung in that case and stick with panasonic. i service the units myself as i dont see a reason for wasting 150 bucks for a "service" when all you really need to do is wash the outdoort unit (5 min job) vaccum the inside condenser and clean the inside blower. Also the taking down degasing and refilling is very wastefull and shortens the lifespan of the unit. my panasonic inverters are now 8 yrs old and still run almost flawless even though they run 24/7.

It's RM150 if it involves gassing/degassing. My local AC tech charges RM30 for both inverters/non inverters if just the cleaning that you require

PJUSA, I know Kim Sim has done a video on another thread re: cleaning for certain models. It would be good to share some of this for the sake of DIY for those wants to learn more. I certainly would. How to clean indoor, outdoor, blower, drainpan, etc. Thanks for enlightening as this goes a long way to reduce household costs esp w AC maintenance and upkeep.

actually for panasonic inverter models its simple: for the outdoor blower i use a diluted kitchen cleaner solution, spray, let it soak for a a minute or so and hose down. if any dirt still stuck at the back, can give a gentle wipe with a wet cloth. done.

indoor unit: take of casing: remove louvre carefully, take out filter, remove the front casing (two screws). if you want to clean like that you can already clean the condenser (spray with water after vacuuming the dust if any). water goes down the drainpan. then what i do is clean the drain pipe by pouring around 100 ml chlorine directly in the water outlet (its corrisive so dont let it touch the metal parts. ideally use a syringe to inject. let the chlorine rinse through the drain pipe, wait for the solution to come out at the other end of the pipe then flush with 2-3 l plain water to flush out any debris.

next and last is the blower. i normally remove the drain pipe (just clipped on anyway) and then use a wet brush to remove the dust from the blower. if you want to do it more detailed you can remove the blower fan as follows: lossen the maste screw at the right ahnd side of the blower then you need to just pull the condenser gently (!) at the left hand side towards you. this will allow you to access the rubber holder for the blower fan. pull out towards you, then pull to the left, blower fan is out. take it and wash fan and the drain pipe under running water with some cleaning solution (kitchen cleaner works great) dry and put back (dont forget to tighten the master screw!!) and reverse assemble. done. wipe all covers that you put back beforehand and also clean the part behind the blower wheel before you put it back!

normally either way will take a total of 15-20 mintutes for this depending on your experience with the unit. it can be done by one person but two is quicker and easier. i dont see why i would want to pay a lot of money to AC people for that. if they dismantle i get a clean unit but reduced lifespan if they do without taking down, they just clean very cincai so its dirty soon after (albeit you only pay like 30 bucks for that... still not worth the money...).

unit is cleaned every 3 months that way. no problems. no refill or service ever required.

hope this helps.

Hi I just installed my new aircon .


Sanyo Sap-KC12bgs3.1290w /12000 but/h 1.5hp non-inverter.

Living room 7mx3.5mx3m

Did I get the correct size?

By setting to 25dg already cooling. 18c very dingin gigit Liao.

Did I oversized or just right?

What if I say it is undersized? You will change?
For living room, you need to cool down to 25-26°C, no need to set lower. You only need to set lower when you have a crowd of > 6.
As the cool air from blower unit will be on maximum.

Haha lan lan Liao ma. I think is very cooling already at 25c .

Just wondering if 1pk will be cool also. But I believe if 1pk outdoor unit will need to work Harder to achieve the temp.

So non-inverter for living room did I made a right choice ? Usage is 5 hr/day. Got consider inverter but scare not cooling compare to non-inverter .

You must understand the working principle of air cond.
When the room is warm, both of them will go to the max.
When the temperature reached the set temperature, non inverter will cut off totally while inverter will ramp down the power.
What makes an air cond to safe power is how fast it cuts off.

Ic, so let's say my ac is 1290 watt so power consume will be 12.9kw/h. From power on to reach 25c say need 15mins. Then outdoor unit will cutoff . after cut off is it still calculate 12.9kw/h?

In this case go for inverter..

Cause inverter got part load, once the temp are reached will be runing minimum of power input just 350w only.

If you has check with specs would indicate on Min. 350-1250w Max (normal 1050w)

Is 1.2 units per hour, 12.9 units per hour you will be a dead duck already
When the outdoor unit cutoffs, it should using minimum power only, still have to depend how you set it.
If you set fan to Auto, then it will cut off the fan also.

i don't see much saving too .. my inverter ac

What model?

How big of your area

What is the capacity?

wat is ur usage trend ?

Thanks!

If the duration daily are < 4-5 hours, it is same as non inverter.

agreed , it cool down kinda slow ... normal non-inverter really a lot faster...

Because the non inverter when working will work at max and totally stop when not working.
