Buying a new AC for your home? It is indeed a huge investment that you are making. Care should be taken that you choose the right system for your home that will ensure maximum cooling but minimum energy bills. Before you go in for a new AC installation, you have to calculate the size of the rooms , do a heat gain and loss calculation, see the duct design of the equipment and other features to get maximum benefit from the cooling equipment. This is where tools like Manual S come handy.
Any AC installation should follow the strict procedures of Air Conditioning Contractors of America (ACCA) using tools like Manual J (for load calculations), Manual D (for duct designs) and Manual S (for equipment sizing and choosing).
Manual S is a tool that helps you to choose the size and capacity of your AC that will be required to cool your home efficiently. Any AC that is too small for your room produces hot and cold spots in your room, and any AC that is too big switches on and off frequently.
