Load Calculation

A load calculation is the process of figuring out how much heating and cooling capacity a space actually needs. It factors in square footage, ceiling height, insulation quality, window placement and size, sun exposure, and even how many people typically occupy the space. The output tells you what BTU size system will actually keep the room comfortable without being oversized or undersized. Skipping this step and just guessing based on square footage alone is how you end up with a system that short-cycles, struggles in extreme temperatures, or can't keep up on the hottest days.
