As of January 1, 2015, there are New DOE Efficiency Standards implementations that have gone into effect. 76 Fed. Reg. 37408
Northern States – Minimum 13 SEER air conditioning remains the standard, but heat pumps efficiency's went up to 14 SEER and 8.2 HSPF.
Southern States – Minimum efficiency went up to 14 SEER for both air conditioning and heat pumps and 8.2 HSPF for heat pumps. The 8.2 HSPF/14 SEER heat pump rating will become a national standard.
Southwestern States – Minimum efficiency went up to 14 SEER for air conditioning, but there is a new standard for EER that will call for 12.2 EER for systems less than 45,000 BTUH and 11.7 EER for systems over 45,000 BTUH. Heat pumps require national standard of 14 SEER and 8.2 HSPF
Customers in all regions (Northern, Southern and Southwestern) have the ability to purchase and have shipped lower efficiency rated equipment from our website to any state within the contiguous 48 United States of America. It is the customers sole responsibility to abide by these NEW DOE efficiency standards.
