Residential air conditioners and heat pumps were first required to carry an energy label in 1987 and have been subject to Minimum Energy Performance Standards (MEPS) since 2004. Larger three phase air conditioners that are normally used in non-residential situations have been regulated for MEPS since 2001 and have a voluntary labeling scheme.
