In short if the AC pattern works like federal hwy jam ie used at sensible temp 25C get inverter. The INV save lots of energy from the frequent stop start because 25C quite easy to achieve target.

If the AC pattern constantly full tekan like empty highway ie used at 16C then NON will be the same as INV power usage.

INV pro in situation where many stop starts of the compressor. If never stop (16C freezer target) it also work at full speed so no savings.

Also if the aircon seldom use like storeroom only use few days in a whole year, NON also good enough coz INV OPEX savings cannot cover the INV higher CAPEX for such little usage.

Hi guys, need some some advice here.
I'm thinking what kind of aircond to get for my kitchen + dining area.
Currently aiming Daikin cassette 2.0hp (FCF50C). Is it necessary to install a cassette or just a wall mounted will do?

Install a wall mounted so that you can position the vent to blow towards the dinning table and kitchen area.

Good point. Decided to go for wall mounted. Kitchen and dining no need to be very cold also.
Thank you!

Anyone extends warranty for air cond? Am going to install Daikin inverter series in condo, is it worthy to extend another 3 years (RM205 for 1.0HP; RM219 for 1.5HP) as advised by salesperson? According to him, Daikin has 35% of becoming faulty zzz.

Guys, for 1.0 non inverter air cond, between pana and daikin, which is recommended if the price is the same? I am being offered the same price for this 2 brands, so wondering which to take.

Any reason u still go for daikin even when it is 35% faulty rate? What about the rate of other brands?

Generally, better known brands will less likely to fail and that is one reason why it cost more than lesser known brands unless one is unlucky to receive a lemon unit.

Extended warranty by retailers are normally insurance based coverage and all claims are subject to waiting period pending approval similar to a vehicle claim.

If you are looking for extended warranty I suggest you buy a brand that is directly provided by the manufacturer. If at all there is a fault, repairs or replacement will be provided with no questions.

Is not feasible to buy extended warranty for a product which is of low value where repair cost is 30 to 50% of a new set.

I have been using Pana non invertor for many many years and have a total of 15 units. Is a good choice for me. No major issues other than 1 lemon unit received.

I've never bought extended warranty especially with Sharp brand

Then you'll probably choose which one has higher efficiency thus saving you some $$ long run

Nope. More like upselling because that 200 sth can replace almost everything in terms of parts..except compressor which usually warranted for 5/7/10 yrs..

If you gonna use it frequently ie everyday, a NON is cheaper by 2 or 3 hundred but the increase in TNB bill at 0.518 per unit gonna add up prettt fast that it makes more sense to get inverter.

Thanks guys for the feedback.

Thanks for the feedback. If in term of reliability, will a inverter or a non inverter will last longer in the long run?

Reliability of any appliances mainly depends on the user.

For my current place, the non invertor ACs are used daily and 80% are more than 10 years.

Temperature are set between 23 to 25 depending on weather. Filters are cleaned every 3 months. General diy cleaning yearly and major every 2 years.

Finally, you need the correct hp, otherwise, the best brand or tech will also fail.

Ya, totally understand it. What i mean is assuming all other factors are constant, wondering which is more reliable. By right should be non inverter right since it has less parts and is a old tech.

Yes, if there is more or different parts, generally there will be more to replace if things goes wrong and is not always necessary that 'extra' parts in invertor.

Invertor and non operate differently and hence the need for 'extra' or different parts, otherwise it wont work.

Each have different end result albeilt both are air cond.

Why would a manufacturer makes an invertor less reliable than a non if is providing the same warranty period for both ?

I have experienced and also known few pana non invertor users kaput within 5 years. I maintained it like all other ACs in my house and yet it kaput.

Unless there are available data, is difficult to confirm your doubt.

Generally a NON's compressor will be harsher use than an INV and thus the wty period of compressor motor also reflect that Assuming no hardware failure, the usual cause of AC failure after ten plus yrs would be the electronics failing due to capacitor leak or aging (old age electronic failure)

Hmm, icic. Thanks for the valuable input.

Hi sifus, my house has only 10ft ceiling height before the plaster, but I would like to install cassette aircond without sacrificing the height too much. I was told by the contractor that the minimum clearance is 1ft.

Anyone know which brand & model has the lowest/minimum ceiling clearance, for a 1.5/2.0hp cassette? Thank you.

Legit just saw your post.. apologies for the late reply..

In regards to your questions aforementioned:

1. My room is about 400sq feet ;

2. 1.5hp x 2 units (as mentioned in my post, a 1.5hp x-deluxe and a 1.5hp x- premium.. i do have a door partition between my “living room” area of my bedroom and my actual “bed area”.. soo at one time, i only turn on 1 a.c. based on room occupancy..;

3. My usage for Hot season i.e. March till July is about 82kwh/month ( for my bed area unit) and about 20 kwh for my living area)… my preference temp is 26 degrees on high fan with auto swing)… take note that on average the unit is powered on for 7 hrs in my bed area and around 2 hrs for my living room area daily.. during rainy season, i sometimes do not turn on the a.c. Case in point: since 20/8, i’ve mostly used my ceiling fan as my room temp hovers around 26 degrees at night and around 24 in the early morning.. KK has been raining extensively lately ( i live next to a forest area and with the rainy season, u could really feel the fresh crisp air billowing through the windows which btw have mosquito netting )

Short answer: outstanding energy savings.. just ensure that your set temp is achievable and your a.c. Is at the right size / oversize.. never ever undersize, then you’ll see the savings

4. I am not really good at suggesting… however, just get yourself a 2.0hp inverter unit, it can easily match / exceed your cooling requirements.. you may never know when you need the extra oomph.. and with inverter, it’ll continually adjust the speed of the compressor to match your set temperature.. you’ll never go wrong with inverter ( unless it breaks down, so choose wisely).. I’ll always go with Panasonic or Daikin since both are manufactured in Malaysia, hence an abundance of parts and top notch after sales (based on my own experience)… for Panasonic, hands down x-premium inverter if you have the budget or to save cost, x-deluxe inverter ( the 2.0 hp model even has a left right swing compared to the 1.0 n 1.5hp models)… for Daikin, Smarto series hands down as its the only one with a streamer technology ( equivalent to Nanoe-x) and has an added PM 2.5 filter built it… but its costly vis a vis with Panasonic, you’re not getting that “bang for your buck” purchase.. Gree is another option (my sister installed a 2.0hp Queen series inverter) and it does its job well.. except the indoor unit is quite noisy (at medium to high fan speed) and the remote is mehh, the wifi function only turns the a.c. On/off, nothing fancy unlike Panasonic’s iteration.. the outdoor unit is silent though, I’ll give them that.. oh and the Gree is only 4 stars rated but at RM2150, its s bargain!!! But I still cant say how it will fare long term vs heavyweights Panasonic and Daikin.. LG is a good option too, but its quite pricey compared to locally manufactured Panasonic and Daikin (when compared to LG’s 2.0hp dual inverter premium).. the advantages include ability to control your compressor speed (at 40%, 60%, 80% or 100%) and that it has a lower operating frequency (circa 3400 btu at its lowest vs 3750 btu for the Pana x-premium… the difference is negligible though)… the LG only has 4 star energy rating though ( cant confirm this, but seen it somewhere before)…

Anyways do research and good luck on your purchase!

Hi, I know I asked this before, but my final choices are these, hope to get some feedback before I place ordered,

Planned to go with below for 4 rooms 1.0hp and 1 living room 2.0hp with all Sharp

SHARP AHX9VED2 R32 1.0HP INVERTER
AHX9VED2 (INDOOR)+
AUX9VED2 (OUTDOOR)
9700 BTU

SHARP AHX18VED2 R32 2.0HP INVERTER
AHX18VED2 (INDOOR)+
AUX18VED2 (OUTDOOR)
18000 BTU

Or should I go with mixed brand with Panasonic? Currently planned for living room and main room with Panasonic if quality is much difference or able to sustain for longer duration/maintenance because of frequent usage

Able to find 1.0hp Panasonic but might need your comment on 2.0hp

PANASONIC CS-XPU10WKH-1 1.0HP X-DELUXE INVERTER R32 AERO SERIES
WITH NANO TECHNOLOGY AIR COND
CS-XPU10WKH-1 (INDOOR) +
CU-XPU10WKH-1 (OUTDOOR)
9680 BTU

I login this forum everyday just to check whether you have reply or not no problem mate

1. Wow 400sqft so big.

2. Luckily you have partition between living room area of bedroom and actual bed area so you can separate between 2 ac. Can choose which ac to on or off - save electricity.

3. 82kw for 1 month for daily 7 hours used - freaking save electricity dude. I also normally set 26-28 depends on climate on a day. My bad i undersize my ac on my master bedroom coz im not considering heat coming from roof as my bedroom on top floor.(living an apartment before).

4. My LG is also good but the problem is it really struggling to maintain the set temperature even at 28 on hot day maybe due to underpower ac. After considering what you have said and comparing between LG Dual Inverter 2hp and this Panasonic X-Premium Inverter 2hp i'll go with Panasonic because this model got higher rated btu 19,000 comparing LG only got 18,000 rated btu.

Many thanks to your explanation and advice
