Many factors affect the sizing and specifications of your system, including square footage, insulation, window surface and configuration, geographic location of your home, and duct sizing and arrangement. A technician from iHome Services can perform an in-home load analysis to determine which equipment combinations will perfectly suit your home and your family’s needs. Depending on the construction of your home, one (1) ton of air conditioning can cool anywhere from 300 to 800 square feet. You can ensure that the system you purchase is the right size and not smaller or larger than you require, by having your heating and cooling needs evaluated by a licensed professional.
