1) How come inverter ACs need to be 0.5hp more than conventional ACs if we are cooling the same sized room

2) When does inverter ACs do not make sense?

3) Are there Malaysian websites that review ACs?

So that isn't how inverter ACs are marketed in Malaysia?

BTW I'm from the Philippines and this is one of the few forums that talks about inverter ACs without ASEAN.

I honestly cannot sleep.

My worry is that I underloaded the ACs I got for the rooms. I also worry that I will be paying more on my power bill.

17sqm
- East facing window that has tint and blackout curtains
- Cement walls all around
- 2.5m ceiling
- Top floor
- Wooden floor and ceiling
- Two wooden doors
- One person
- One desktop with LED display
-- 2.0hp LG HS-18ISM
--- EER 13.9 Kj/h.W
--- Cooling capacity of 19,438 Kj/h or 18,423 Btu/h
(Non-inverter AC would be 1.0 to 1.5hp for 17sqm)

Thanks kimsim.

Since reading the 0.5hp increase allowance for inverter ACs I wondered why this was a Philippine-specific rule. I say this because I cannot find any non-Philippine reference on this. The Malaysians I asked on a forum never heard of it. India's "Consumer Voice" magazine does not mention this either.

I think this started with older or some inverter AC models that did not have a rapid cooling function like LG's "Jet Cool". This feature I have.

It's something I did not expect so I am half disappointed

I talked to the surveyor and he said 1.5hp inverter can cool 17sqm but countered the extra 0.5hp would give give me the adequate overhead when days become warmer and my power consumption would be better in the long run with the extra leg room. I hope he's right or else I just bought extra performance that i will never or rarely use.

It is also possible that is that they are compensating for poorly insulated rooms to avoid complaints from unhappy customers. To which I cannot blame them for doing so.

Or they just wanted to push models that are slow sellers or gave them a better margin per unit sold.

In future purchases I suggest those buying to read carefully the inverter ac they are eyeing for rapid cooling functionalities like LG's "Jet Cool". Other brand owners should see and share what it is named with their units.

I knew this function was present in LG ACs but under the name of "Himalayan Cool" for the South Asian market but seeming the functionality wasn't named in any PH specific product I didn't bother looking for it. Renaming the function from one market to the next may make it better understood in different cultures but it is confusing leading to wrong purchases. Bad move LG.
