What is 13 SEER?

The U.S. charges the Department of Energy (DOE) with managing the country’s use of gas, electricity, natural gas, and other forms of energy. In accordance with their goals, the DOE is focusing on initiating regulations to create air conditioners and heating systems that operate using less energy.

In other words, the DOE gradually raises the requirements for SEER ratings:

• Seasonal
• Energy
• Efficiency
• Ratio

For almost 10 years, the minimum efficiency standard has been 10 SEER. On January 22, 2006, the minimum standard will be raised to 13 SEER. The new 13 SEER standard requires manufacturers to cease production of 10 SEER components on January 22, 2006.

No one can predict how long current equipment rated less than 13 SEER may remain in use, but manufacturers will be prohibited by law to build less-efficient components as of January 23, 2006. The law will ultimately result in a phase-out of less efficient components altogether.

The 13 SEER minimum requirements affect everyone: consumers, HVAC dealers, and manufacturers of air conditioners and heat pumps. The 13 SEER minimum efficiency law is unavoidable.
