June 17, 20242 yr Hi It's me again! Sorry for all the posts, just handling different sections and would love some expert opinions, to check installers ideas against! A Few Notes Bed 1 is 6m x 6m Lounge is 12m x 6m Bed 3,4,5 are 4x4m Blue = internal units Yellow = Condenser and suggested piping route We've placed the condensers on concrete roofs, the rest of the roofing is thatch. North is towards the bottom right. House is thatch with a higher internal height. There are lots of windows and glass sliding doors. A Few Quick Questions Where would you place aircons? What sizing would you go for in each room? Any particular brands you'd recommend? I really appreciate any insights and help!
June 17, 20242 yr Author NOTE: Condensers on concrete roofs will be about 1m higher than the indoor units.

What sizing would you go for in each room? Any particular brands you'd recommend? I really appreciate any insights and help! For the smaller bedrooms I would go with 9000 BTU, the larger bedroom 12000BTU. The living area has 2 units, so probably two 12kBTU units. One thing I would recommend is to make sure the aircon is placed in the living room where it does not blow air directly over a place somebody will be sitting, I made that mistake in my house. The installer told me I can change the direction it blows air, that is a lie, it mainly blows air directly forward. I would recommend LG Dual inverter aircons, they are great. Very quiet units both inside and outside. A lot of this advise is dependent on where your house is. In Upington for example I would recommend bigger units. Also, if your ceiling is not well insulated you might also want to bump up the capacities. Edited June 18, 20242 yr by HendrikBigChief

Thanks for the detailed response! 1) For smaller rooms, do you think it's enough? https://www.curries.co.za/aircon-size.html While the room is 16m2 surely the high thatch ceiling and glass sliding door mean we need a larger model? 2) Where in the lounge would you place it then?

When in doubt, bump up the capacity. As you have high ceilings, yes, go for 12000BTU in the smaller rooms. 2. I would move it down on your map, more towards to door away from the seating area. You also don't want the aircon above a TV. They can leak water and pieces of ice sometimes. That will kill a TV very fast. Edited June 18, 20242 yr by HendrikBigChief
June 18, 20242 yr I remember it being recommended that you should try not to oversize the aircon for a room as the compressor would be switching on and off a lot more frequently when cycling which causes more wear and tear on the unit and uses more inrush current when it starts up. I guess this is no longer the case if the aircon is an inverter type as it can ramp up and down the compressor to meet demand
