To design your heating, venting, and air conditioning systems, Custom Engineering starts with a comprehensive energy modeling analysis. We take into account your building materials, windows, and orientation to the sun. We then calculate the right cooling or heating load and determine the proper equipment. Throughout the project, we follow all industry specifications established by the American Society of Heating, Refrigerating and Air-Conditioning Engineers. As members of the U.S. Green Building Council, we can also customize your system to attain your desired level of LEED certification.
