According to the Department of Energy, heating your home typically represents about 45% of your utility bill.[1] That’s a lot! And, that’s why there is so much interest in high efficiency heating and cooling systems. When it comes to furnaces, “efficiency” refers to how effectively they can convert heating energy from a fuel source into warm, comfortable heat for your home. Today’s highest efficiency furnaces can provide comfort with up to 98.5% AFUE efficiency. These energy-efficient heating machines offer great appeal to homeowners interested in having the most recent technology available.

These models do a great job at converting fuel into heat. Less heating fuel is needed for comfort, resulting in less emissions, reducing energy costs and environmental impact. In many cases Carrier high efficient furnaces include technology that can produce enhanced comfort benefits and quieter operation.

Regardless of which benefit appeals to you the most, we’ve come a long way from the days of 56 – 70% AFUE efficiency, furnaces that wouldn’t even meet the Department of Energy’s current minimum requirement. Keep in mind that generally, furnaces that deliver higher efficiency heating often come with higher price tags as well. The price difference is partially offset by reduced heating bills over the life of your new heating equipment.

Available in variety of types, from a variable-capacity gas furnace to a two-stage gas furnace. A range of options to meet everyone’s heating needs.

Also, keep in mind that other heating systems, such as air-source heat pumps and geothermal systems, operate on different principles.
