Single Package Vertical Air Conditioners and Heat Pumps



Department of Energy

Manufacturers have been required to comply with the Department of Energy’s energy conservation standards for single package vertical air conditioners and heat pumps as a separate equipment class since 2008. Before 2010, this equipment was regulated under the broader scope of commercial air conditioning and heating equipment. Single package vertical air conditioners and heat pumps are commercial air conditioning and heating equipment with its main components arranged in a vertical fashion. They are mainly used in modular classrooms, modular office buildings, telecom shelters, and hotels, and are typically installed on the outside of an exterior wall or in a closet against an exterior wall but inside the building.


Ongoing Rulemakings
Test Procedures for Single-Package Vertical Air Conditioners and Heat Pumps

Summary: The Department of Energy (DOE) is examining whether to amend the current test procedure in place for single-package vertical air conditioners and heat pumps. As a result of this effort, DOE may propose and amend the test procedures for this equipment, or issue a determination that no amendments to the current test procedures are required.

Current Efficiency Standards

For the purpose of this regulation, single package vertical air conditioners include any air-cooled commercial package air conditioner that is factory-assembled as a single package, and that (1) has major components arranged vertically, (2) is an encased combination of cooling and optional heating components, and (3) is intended for exterior mounting on, adjacent interior to, or through an outside wall. Single package vertical heat pumps are a single package vertical air conditioner that uses reverse cycle refrigeration as its primary heat source.

Single package vertical air conditioners and heat pumps manufactured on or after January 1, 2010 and distributed in commerce, as defined by 10 CFR 431.92, must meet the energy conservation standards specified in the Code of Federal Regulations, 10 CFR Part 431.97(b).


Each single package vertical air conditioner and single package vertical heat pump manufactured on and after September 23, 2019 must meet the applicable minimum energy conservation standard level(s) set forth in this section.
