Hi sifus, need some help with picking the HP for my room
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
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?
