Hybrid Heating and Cooling System

Hybrid Heating and Cooling System or Dual fuel is a dynamic system that exhibit both constant and isolated dynamic behavior. It means that a system has tendency to manage flow and jump activities to be performed at a same time.  The dual fuels system works on a simple principle i.e.  They use outside air as a source for operating the system.  When the temperature falls outside then the system switches to gas fuel furnace. 

How Hybrid Cooling and Heating System works

A Dual-Fuel or hybrid system uses heat pump with a gas furnace for work. The outdoor section is works as a heat pump and the indoor section, instead of using air handler, uses gas furnace with a coil.  Outdoor system is used to set the temperature of the house until the outdoor air reaches to a specific degree. As soon as the temperature falls below the set degree the system switches to gas furnace for heating.
