Dept. of Energy Seeks Comments on A/C Rating Methods
As the Jan. 1, 2015, implementation date for split system central air conditioner regional standards approaches, the U.S. Dept. of Energy (DOE) seeks comments on proposed guidance for rating and application of this equipment. One of the draft guidance documents related to system installation vs. component retrofit is of particular interest to installing contractors.
The DOE has maintained that split air conditioner and heat pump systems must be tested and rated in a specific process. The result produces SEER- rated systems for compliant installations. This guidance considers whether an outdoor condensing unit may be actually classed as a component allowing retrofit installations with existing indoor coils, possibly not tested or rated as a system. For installers, this would define whether they would install a system with parts or be able to use components, an option that could save consumers money.

PHCC first learned of this comment period during a regular meeting of the DOE’s Appliance Standards and Rulemaking Federal Advisory Committee, of which PHCC Vice President of Code and Technical Services Chuck White is a member.
