In October of 2011, the Department of Energy (DOE) released new minimum furnace efficiency standards for the U.S., effective May 1, 2013. At that time, the Annual Fuel Utilization Efficiency (AFUE) for newly installed, non-weatherized (indoor) residential gas furnaces will increase from 78 to 90 percent for the 30 states in the northern region of the U.S., which includes Ohio. For all other states, the new standard will increase from 78 to 80 percent.

These standards were initiated and submitted to the DOE by a collective group of energy and environmental conservationists, manufacturers and efficiency advocates. Analysis of these new furnace efficiency standards points to several long range as well as immediate benefits for both the consumer and the environment. 

Long-range environmental impact
Across the U.S., residential heating system use generates a sizable portion of the country's greenhouse gases collectively every year. It is estimated that the new standards will greatly boost the overall savings in energy usage. That savings equals a reduction in greenhouse gas emissions by millions of metric tons of CO2. 

Savings for the consumer
The 12 percent increase in furnace efficiency directly affects consumers in the northern region by reducing energy costs up front and over the life of the furnace. Since the efficiency ratings do not take into consideration residual heat loss from external factors such as leaky air ducts, filters and insulation, proper maintenance and other energy-efficient measures are crucial for ensuring the best possible performance of the furnace system.
