During my architectural apprenticeship days, we had this one project where I was assigned to do a mechanical layout. I dread doing that. I spent long hours studying the sizes of air-conditioning systems that will be installed and plot the areas where they would be located. I can remember browsing a lot of brochures with all those air-conditioning specs. One of them is Split System Air Conditioners which I find to be one of the most interesting air-conditioners out in the market. They’re more affordable and splitting the hot side from the cold side of the air conditioner, and are flexible for zoning, heating, or cooling individual rooms.
