A true split system will have both indoor and outdoor units and relies on ductwork to deliver treated air. Go ahead and choose split system even if you have a furnace only, as long as your current equipment isn’t geothermal or packaged.
A geothermal system has piping underground, or in a well or pond, and uses a special heat pump to provide treated air through ductwork. Choose geothermal if you have a geothermal system—or would like to switch to one.
Packaged products are complete heating and cooling or cooling-only systems that sit entirely outside the home, either on the roof or the ground and use ductwork to deliver treated air. Choose this option if your current system is packaged, or if you want to switch to a packaged solution.
DUCTLESS MINI SPLIT SYSTEM
Whereas traditional heat pumps and central air conditioning systems force cooled and heated air through ducts, ductless systems deliver air directly into different zones. They are comprised of a small outdoor unit and one or more indoor units that require nothing more than mounting capabilities and access to electricity.
Sometimes referred to as split systems, multi-split systems, or split-ductless systems, ductless cooling and heating offers home and business owners a cost-effective way to replace inefficient window units, space heaters and electric baseboard heaters. They can be installed in home additions, new construction, condominiums and apartments, or to improve temperature control in specific rooms. Ductless systems can even be fit for buildings that currently use ducted forced-air systems.
