Dear all, wanted to know about aircond sizing for my 500sqft living room. If according to Daikin, Acson and Panasonic online sizing, seems like I need 3HP to cooldown the room. But if I look at other countries or online calculator, seems like a 1.5-2HP aircond should do the job.

Hi everyone, my Daikin Smarto 2hp r32 aircond compressor pressure is 100psi to 110psi. The person checking said it is not enough and needs to be charged/increases to 150psi. Is this correct? Can’t find any information on this. Thanks!
