Energy Efficiency Standards
Air conditioning manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards since 1992. In January, 2015, a new “regionalized standard” for residential products went into effect. Today, the minimum efficiency standard that effects you is determined by the location where the system is to be installed. The standards are not retroactive, so you do not have to replace older, less efficient equipment. However, when you decide that it is time to replace your comfort system, the new system must be compliant.
