Hello sifus, hope to understand more about AC from you all.

I just got the keys to my condo, here is the floor plan. Ceiling height is 10ft.



I am trying to calculate the proper size AC for my unit. Plan to install 3 units. One in Living, one in Bedroom 1 and 1 in Master Bedroom.

Currently only will have 2 occupants in Master Bedroom. Bedroom 1 will be rarely used.

I used this website to calculate:

Bedroom 1 is around 100sqft, and it just requires a 1hp. Since it will be rarely used, I plan to get a non inverter.

Master Bedroom according to my rough calculation is around 167 sqft. Using the calculator I would need a 1.5hp. and this will be frequently used >8hrs every night, so it is better to get an inverter type for energy savings.

Living Room I calculated to about 385 sqft. This will require a 3hp. This unit will most likely be turned on quite frequently so it will be a inverter type as well.

So in total I will require 1hp non inverter, 1.5hp inverter and 3hp inverter.

Is my estimation correct? Before I got the keys I showed my floor plan to an electrical store and they recommended 1hp for master bedroom and bedroom 1, and 1.5hp for living room. I am wondering why is it so different.

Thank you in advance!

Thanks ceo684 for your help!

I will look to get a 1.0hp NON for bedroom 1, 1.5hp INV for Master Bedroom and 2.5hp INV for Living Room.
