8HP or 1HP AC for a 5sqm Bedroom + Occasionally Cooling a 13sqm Sala?
Hi guys! Need some advice on aircon sizing.
Our condo has two bedrooms (5 sqm each) and a combined sala + kitchen that’s around 13 sqm. The ceiling is pretty low, so the overall air volume isn’t that big.
The problem is the sala doesn’t have an aircon provision, so I can’t install a separate AC there.
For now, I’m only planning to install an AC in one of the bedrooms. I feel like a 1 HP unit might be overkill for a 5 sqm bedroom, but I’m also thinking of leaving the bedroom door open sometimes so it can help cool the sala area (13 sqm) too.
Would it make more sense to get a 1 HP instead of a 0.8 HP?
I also don’t know yet how often I’ll actually use it to cool the sala. Most of the time, it’ll probably just be for nighttime use in the bedroom.
For those who have a similar setup, will my electric bill be significantly higher if I get a 1 HP and mostly use it only for the bedroom? Or should I just stick with a 0.8 HP and accept that it probably won’t be enough if I want some cooling in the sala?
Would appreciate your thoughts and real-world experiences. Thanks!
