Overview: Bigger is not always better with HVAC systems. Determining the correct size of residential heating and cooling equipment is key to achieving comfortable interior conditions ? temperature and humidity ? and saving on initial and operating costs. Size of cooling systems is particularly critical for optimal energy efficiency and comfort. When equipment is oversized, initial costs are higher, efficiency is reduced, energy costs increase, and comfort may be compromised. One Florida study showed a typical 9 percent increase in annual space cooling electricity usage for units that were oversized by 50 percent or more.
