A “split system” simply means that a home’s heating and cooling systems are “split” both inside and outside your home. In most cases, a split system will consist of the following parts.

• Gas Furnace – Provides heating white also circulating air year round through a blower motor
• Evaporator coil – The indoor part of the outdoor AC unit that chills the warm air
• Air conditioner or Heat Pump – Works with the evaporator coil to cool the home 
• Air Ducts ― Distributes the conditioned air throughout your home through air ducts and returns
• Control or Thermostat ― The brains and control point of the HVAC system 
• Indoor Air Quality Accessories ― Designed to purify, humidify, and freshen the air for a healthier indoor environment, they include air filtration, humidifiers and dehumidifiers.
