currently I'm a small house.
the master bedroom already installed an aircond, but an old one.
sucks bill like hell (daily use for 5hrs costs me RM200).
Mivea brand, require abour 15mins to feel the chill after turning on.

thus, planning on replacing it.
asking recommendation for brand/model which is most economical.
however, I have limited budget, best if can get less than <RM1000, but can stretch only till RM1200

Gree

RM1200 can get 1HP (non-inverter) including installation.

I think firstly we should determine whether you need a 1 or 1.5hp aircon..by your room sizing

yes....determine your room size first (to see how many hp aircond you need)

then see you need to install new copper piping (usually newer aircond uses new piping)

for long hour usage, just go for inverter (even though its slightly pricier than non inverter)

10ftx10ft bedroom.
1hp should be enough right?

planning to keep it on long (~10hrs/day)
- inverter type is more economical right?

I had surveyed some.
interested in Sharp brand (due to price range <RM1500, +inverter).

I found 2 models (forgot to note down the model name/no., sorry),:
both rated 5-stars,
but 1 is rated for about 800kwt/H per year,
another one is rated ~1600kwt/H per year (I hope I get the unit right),
which one is more economical?
(aiming on reducing electricity bill from RM200 to around RM100, while using the aircond daily)

10 x 10ft same with my room
1hp more than enuf

i would suggest haier 1hp inverter

my fren office using haier 2.5hp inverter, monthly electric bill saved rm600++ surprisingly

not sure if the power consumption of one model can be double of the other.

1hp more than enough for 100 sq ft

Yes Inverter

You should be looking at EER = (BTU rating / Watts) to compare efficiency of AC.

https://home.howstuffworks.com/ac5.htm

https://www.techlicious.com/how-to/select-t...ir-conditioner/

A room air conditioner's efficiency is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling capacity (in British thermal units [Btu] per hour) to the power input (in watts). The higher the EER rating, the more efficient the air conditioner. Each increase of 1.0 on the EER scale represents a 10% increase in energy efficiency.

When buying a new room air conditioner, information about the EER can be found on the EnergyGuide label for the unit. Look for an EER of at least 12

Different aircon sizing even from same model line can have different EER ratings.
