Life Cycle Cost Savings

For most applications, energy-efficient furnaces have the lowest life-cycle cost. For example, EPA has estimated that an Energy Star-qualified gas furnace can save a typical user $995 in energy costs over the life of the furnace, while avoiding 15,325 pounds of greenhouse gas emissions.

An efficient product is cost effective when the energy costs saved over the life of the product exceed the additional upfront cost (if any) of the more efficient model. Energy Star considers both upfront costs and lifetime energy cost savings when setting required efficiency levels. Federal purchasers can assume that Energy Star-qualified products are life-cycle cost effective. On its Purchasing & Procurement page, Energy Star offers MS-Excel-based calculators to estimate how much money and energy you can save purchasing ENERGY STAR furnaces.

Additional Guidance

Energy Star notes that different gas furnace efficiency requirements and labels are used for different regions of the country. Certified gas furnaces in the southern half of the U.S., where homes require less heat, will be labeled with a unique “U.S. South” ENERGY STAR logo. Certified gas furnaces in the northern half of the U.S. will be labeled with the standard ENERGY STAR logo. 

The ENERGY STAR Most Efficient program identifies the most efficient products among those that qualify for the ENERGY STAR in particular product categories. Product categories were selected and recognition criteria were established to ensure that products that receive this recognition demonstrate efficiency performance that is truly exceptional, inspirational, or leading edge. There are Most Efficient criteria for furnaces.

Included products: Non-weatherized residential gas furnaces, as defined below, are eligible for ENERGY STAR® Most Efficient recognition in 2017. Residential Furnace: A heating unit with a heat input rate of less than 225,000 Btu per hour whose function is the combustion of fossil fuel (natural gas, propane) for space heating with forced hot air. Unit must include burner(s), heat exchanger(s), blower(s) and connections to heating ducts. Unit may also provide hot water for domestic or other use. Excluded products. The following products are not eligible for ENERGY STAR Most Efficient recognition in 2017:  Furnaces intended for commercial installation and/or with a rating of 225,000 Btu/h or higher  Mobile home furnaces  Weatherized gas furnaces  Oil furnaces
