Split System and Hybrid Heat Split System
The most typical heating and cooling systems are split systems, so named because they have an outdoor component with a condenser/compressor and an indoor component with an evaporator coil.
A split system typically includes:
- An air conditioner that cools the refrigerant
- The furnace and evaporator coil, or a fan coil that converts the refrigerant and circulates the air
- Ducts that carry the air throughout your home
- Thermostat, the interface for controlling your system
- Optional air quality accessories such as air cleaners or ventilators that clean the air before it circulates throughout your home
A hybrid split system is a more energy-efficient variation of the split system, and includes all the components of a traditional split system, with a heat pump in place of the air conditioner.
More About Heat Pumps...
Heat pumps provide both heating and cooling in one integrated system, and are much more efficient than traditional central air systems. ASHPs (air source heat pumps) use outside air as a heat source, and GHPs (geothermal heat pumps) use the ground instead of outside air to provide heating and cooling. Because they use the earth's natural heat, GHPs are among the most efficient and comfortable heating and cooling technologies currently available. Although initially expensive, the long-range savings can be substantial.
Heat pumps are widely used in the U.S. and are the best option for maintaining comfort in areas that experience high humidity. They use SEER ratings, and the higher the SEER, the more efficient the system. To get the best performance and highest efficiency possible from your new system, the ACEEE (American Council for an Energy-Efficient Economy) recommends a SEER rating of at least 14.5.
