I think most of the time, premium came with extra such as ionizer, better filter, and even AI cooling. Some like LG only has WiFi on premium model whereas others usually offers wifi on deluxe and premium model.

My brother is using XPU (he's a Panasonic fan). I'm surprised with his power consumption graph as well. He installed a 2.0HP to replace his aging 1.5HP and consume less than 3 kWh/day for 8 hours. Even my son room Samsung 1.0HP premium inverter consume roughly 1.5~1.8kWh/day for same amount of usage. Now interested to test out my LG unit which has a manual setting to set power usage at 100/80/60/40%.

Update:

Just noticed that with Panasonic XPU 1.5hp can reach RM1.7k on Lazada with Sen Heng after voucher and bonus. Installation probably another RM300. Dont forget to redeem tng from Panasonic as well, if not mistaken, around RM80.

After used midea inverter switched from sharp 5 star inverter,  my bill surprisingly dropped RM20 per month/aircond. Same usage same timing daily.. Dont say prc aircond not good liao.. It is as good as japanese brand. And VERY CHEAP somemore.

I realised in KL macam very hard to find Midea aircond in physical shop

My panasonic A/C is only 7-month old, and casing already starts to turn yellow-ish.

It's sad to see how A/C manufacturer are using cheap quality plastic.

X-Deluxe Inverter 1.0HP.
Now that you mentioned it, the plastic cover is indeed very thin, I need to be extra careful when open the case to clean the dust filter.

1.3k after lazada bonus discount

spent another 750 on installation with proper techniques eg: vacuuming, testing etc

Is it normal to have the airconditioner compressors NOT BOLTED to the metal brackets?

Would there be any issues screwing into the metal brackets?

Kinda scared it could easily topple and kill someone.

I'm using the same model too, weirdly the dust filter is clean, but blower is already full of dust after just 3 months.

I used daiso filter more than 12 years? After got daiso then use for my Mitsubishi electric inverter ac
Panasonic not very cold type of ac. Their pre-filter mesh very fine, would be block the airflow. Remove the filter then apply daiso filter should be alright

Not sure if I'm just pure bad luck or Panasonic is really bad.

My Panasonic X-Deluxe Inverter is so problematic.

In just 14 months, Panasonic technicians already came to my house 6 times to fix various problem, gas leak, faulty sensor, faulty blower etc. Thank god all this is covered by warranty.

Now my warranty has ended, suddenly there is a loud vibration coming from the left side of my indoor unit.     

Hopefully yours will not have vibration noise issue.

And do take note that the blower will get dusty very fast, dunno why Panasonic filter is so shitty.
