DOE Publishes Final Air Conditioning, Heat Pump Standards

DOE published in late May a final rule that raises the minimum energy efficiency levels for most air conditioners and heat pumps by 20 percent. The new rule establishes a minimum Seasonal Energy Efficiency Rating (SEER) of 12 for most central air conditioners (including central air conditioning heat pumps) and a minimum Heating Systems Performance Factor (HSFR) of 7.4 for heat pumps. The rule goes into effect on August 6th.

The new rule also withdraws a previous rule, published January 21, 2001, that would have established an SEER of 13 for most central air conditioners. DOE determined that the higher SEER standards were not economically justified. The rule was published in the May 23rd Federal Register and is posted on EREN.
