This is my aircond list. The living, dining, kitchen, are all connected as seen in the floor plan. It's about 12.3 meters in length and 6.7m in width so about 82.4 sqm or a hair under 900 sqft.



The orange circles are where we intend to put them. We can't put them on the shortest beams because we've got light fixtures on the beams. It's inefficient but I hope, still effective enough.

The dining, living, will run in 8 hour intervals except when we're sleeping in which we'll turn them off. The kitchen ac will be turned on to assist if it gets too warm as that's the most powerful one.

We've an earth tube that's placed 1 meter underground and rigged it  through an ERV + a whole house dehumidifier to move air from the outside and hopefully by the time it's chucked into the house, it's cooled down and drier.

The plan is to keep the house at or below 24c and humidity around +-55% at all times.

My question is, based on the conditions built, is this a realistic expectation from my ac? I'm going under the assumption of 20 btu per square feet which assumes I'll need 18,000 btu. I'm getting the 22,500 btu and 30,000 btu ac's to account for the insane heat Malaysia's been smacked with.

Our ac compressors are also underneath the eaves to avoid being in the sun and we've got plants flanking the compressor to hopefully cool the area.

Also, we're getting daikin and mitsubishi because everyone keeps repeating that these two are the best, and also the worst. So we figured we'll just get both and try.
