80% Dual Fuel Split System

An 80% Dual Fuel Split System is a hybrid heating and cooling system that combines two energy sources-typically a gas furnace and an electric heat pump-to maximize energy efficiency and comfort. The term “80%” refers to the efficiency rating of the gas furnace, meaning it converts 80% of the fuel it uses into heat, while the remaining 20% is lost through exhaust.

In a dual fuel system, the heat pump is the primary source for heating and cooling. Heat pumps are highly efficient because they transfer heat rather than generating it. During milder weather, the heat pump handles heating, significantly reducing energy costs compared to relying on gas. However, as outdoor temperatures drop, heat pumps become less effective, and the system automatically switches to the gas furnace for heating, which is better suited for very cold conditions.

The “split system” aspect means that the system consists of two separate components: an outdoor unit (the heat pump) and an indoor unit (the furnace and air handler). These components work together to provide seamless heating and cooling throughout the year.

This system is ideal for regions with varying seasonal temperatures because it optimizes energy use by leveraging the strengths of each energy source. By using the heat pump for much of the year and the gas furnace during colder months, an 80% dual fuel split system provides cost-effective, reliable, and energy-efficient climate control for homes and businesses.
