Conventional air conditioning has been the norm since it was created in the early 1960s. Central air systems offer comfort across your entire home by circulating the cooled air through ductwork that runs through the home. Most conventional systems work by having a split system with indoor and outdoor components. On the outside of the home is a condenser and compressor, while the inside houses the evaporator coils and air handler. Together, this system can remove heat from the air in your home, leaving you with a crisp, cool environment to beat the heat of Minnesota’s summers.
