hi all sifus,I 've read through this post and is looking at the Sharp AHX9VED2 ,so I went to a Expo exhibition last weekend ,almost all the aircon seller were shocked by me asking for Sharp ,they strongly advised me to not go for Sharp
Reasons:
1. Sharp is going to close down
2. All OEM products (aircons)
3. Terrible aftersales service from their/customer experiences(This is the first thing they mentioned whenever I bring up the Sharp brand)

Anyone can share some insight?Is Sharp really that bad?

Hi sifus, need some help with picking the HP for my room icon_question.gif

Room size: 185sqf
Level : 30+ (not top floor)
west facing windows

Here are some of my usage habits:

1.With ceiling fan turn on all night
2. preferred temperature around 25c -28c
3. AC on for 12hrs (8pm to 8am)


Some websites (1 2)is giving me 6k to 8k BTU (if this is true,then 1hp will be sufficient while 1.5 will considered oversizing? )
while some website like https://www.daikin.com.my/heat-calculator/ is giving me a 13k to 15k BTU (if this is true ,then 1hp will be underpowered ,and 1.5 will be borderline sufficient)

why is there a big difference between the BTU calculation rclxub.gif
So should i go for a 1 hp or 1.5hp (1.3hp)?
I dont mind paying more for a 1.5hp upfront, my concern is more on the long term power consumption and lifespan of the AC

because from i 've read online,other than issue caused by undersizing , it seem like oversizing will also lead to short cycle and causing some issue:
increase in humidity and temperature fluctation ( loss of comfort)
increase in wear and tear of the AC from constantly turning on and off,even with an inverter (decrease in AC lifespan)
increase in electrical bill (use more energy starting up and shutting down the motor )

Any sifus can share some idea? nod.gif

First thing to note a 1.5 is actually a 1.3 by virtue of 12k class btu vs 9k class btu of 1.0.
Your room size still got plenty of space to walk around and hold a yoga session so its not a tiny one - 1.3hp inverter will suit your use case well as it has enough capacity (12k nominal btu) and yet slow mode is around 3k btu once it gets to target temp.

Angmoh website calculator is based on their cooler ambient than ours.
