Split-system Air Conditioning

Central air conditioning, like any refrigeration system, works by moving heat energy from one location to another. A split-system air conditioner includes an evaporator coil located inside a home, usually within ductwork otherwise used for forced-air heating. Air is moved through the ductwork and across the air conditioning coil by the furnace blower. Heat energy contained in this air flow is absorbed by a refrigerant, usually R-22 in residential systems, that circulates quietly within the evaporator/condenser loop. The now-heated, gaseous refrigerant is transported through tubing to the outdoor component of the split-system where it enters the condenser coil. A fan in the outdoor unit blows outside air across this coil, thereby reducing the temperature of the refrigerant which then enters a compressor for conversion to its liquid form. The cooled refrigerant re-enters the home on its way to the evaporator coil where a pressure let-down valve allows it to vaporize in order to efficiently collect another load of heat energy.

This quiet, efficient design uses some existing equipment, the furnace blower and forced-air ductwork, in addition to highly reliable air conditioning components to provide whole-house comfort on those sweltering Ontario days and muggy, sleep-depriving nights.

While the split-system air conditioner is the most common for whole-house cooling, other options are available depending on your needs and installation circumstances.
