{"abstract":"The Department of Energy (DOE or Department) has determined that revised energy conservation standards for central air conditioners and heat pumps will result in significant conservation of energy, are technologically feasible, and are economically justified. On this basis, the Department is today amending the existing energy conservation standards for central air conditioners and heat pumps.","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF ENERGY","name":"Energy Department","id":136,"url":"https://www.federalregister.gov/agencies/energy-department","json_url":"https://www.federalregister.gov/api/v1/agencies/136","parent_id":null,"slug":"energy-department"},{"raw_name":"Office of Energy Efficiency and Renewable Energy","name":"Energy Efficiency and Renewable Energy Office","id":137,"url":"https://www.federalregister.gov/agencies/energy-efficiency-and-renewable-energy-office","json_url":"https://www.federalregister.gov/api/v1/agencies/137","parent_id":136,"slug":"energy-efficiency-and-renewable-energy-office"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2001/01/22/01-1790.html","cfr_references":[{"chapter":null,"citation_url":null,"part":430,"title":10}],"citation":"66 FR 7170","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The effective date of this rule is February 21, 2001.","disposition_notes":null,"docket_ids":["Docket Number EE-RM-98-440"],"dockets":[],"document_number":"01-1790","effective_on":"2001-02-21","end_page":7200,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2001/01/22/01-1790.xml","html_url":"https://www.federalregister.gov/documents/2001/01/22/01-1790/energy-conservation-program-for-consumer-products-central-air-conditioners-and-heat-pumps-energy","images":{"ER22JA01.169":{"large":"https://img.federalregister.gov/ER22JA01.169/ER22JA01.169_large.png","medium":"https://img.federalregister.gov/ER22JA01.169/ER22JA01.169_medium.png","original_size":"https://img.federalregister.gov/ER22JA01.169/ER22JA01.169_original_size.png"}},"images_metadata":{"ER22JA01.169":{"large":{"identifier":"ER22JA01.169","content_type":"image/png","size":4710,"width":441,"sha":"6d274288dbcc57d0c5200a2b637223f7","url":"https://img.federalregister.gov/ER22JA01.169/ER22JA01.169_large.png","height":61},"medium":{"identifier":"ER22JA01.169","content_type":"image/png","size":1704,"width":208,"sha":"dac94884309d164d1f75955256728709","url":"https://img.federalregister.gov/ER22JA01.169/ER22JA01.169_medium.png","height":29},"original_size":{"identifier":"ER22JA01.169","content_type":"image/png","size":1160,"width":188,"sha":"3eeb4563c0ab828046c7a3854e65c7a4","url":"https://img.federalregister.gov/ER22JA01.169/ER22JA01.169_original_size.png","height":26}}},"json_url":"https://www.federalregister.gov/api/v1/documents/01-1790?publication_date=2001-01-22","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2001-01-22/01-1790/mods.xml","not_received_for_publication":null,"page_length":31,"page_views":{"count":405,"last_updated":"2026-04-04 14:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2001-01-22/pdf/01-1790.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2001-01-22","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2001/01/22/01-1790.txt","regulation_id_number_info":{"1904-AA77":{"issue":"200204","html_url":"https://www.federalregister.gov/regulations/1904-AA77/energy-efficiency-standards-for-central-air-conditioners-and-heat-pumps","title":"Energy Efficiency Standards for Central Air Conditioners and Heat Pumps","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200204&RIN=1904-AA77&operation=OPERATION_EXPORT_XML","priority_category":"Economically Significant"}},"regulation_id_numbers":["1904-AA77"],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-02-27T17:18:49Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":7170,"subtype":null,"title":"Energy Conservation Program for Consumer Products: Central Air Conditioners and Heat Pumps Energy Conservation Standards","toc_doc":"Energy conservation standards","toc_subject":"Consumer products; energy conservation program:","topics":["Administrative practice and procedure","Energy conservation","Household appliances"],"type":"Rule","volume":66}
