As defined in the Code of Federal Regulations (CFR), “single package vertical air conditioner” means air-cooled commercial package air conditioning and heating equipment that:

(1) Is factory-assembled as a single package that—

(i) Has major components that are arranged vertically;

(ii) Is an encased combination of cooling and optional heating components; and

(iii) Is intended for exterior mounting on, adjacent interior to, or through an outside wall;

(2) Is powered by a single-or 3-phase current;

(3) May contain 1 or more separate indoor grilles, outdoor louvers, various ventilation options, indoor free air discharges, ductwork, well plenum, or sleeves; and

(4) Has heating components that may include electrical resistance, steam, hot water, or gas, but may not include reverse cycle refrigeration as a heating means. 10 CFR 431.92

As defined in the Code of Federal Regulations (CFR), “single package vertical heat pump” means a single package vertical air conditioner that:

(1) Uses reverse cycle refrigeration as its primary heat source; and

(2) May include secondary supplemental heating by means of electrical resistance, steam, hot water, or gas. 10 CFR 431.92

Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for single package vertical air conditioners and heat pumps since 2008.

Recent and Ongoing Activities

DOE has published a Federal Register notice of proposed rulemaking (NOPR); notification of proposed determination (NOPD) pertaining to energy conservation standards for single package vertical air conditioners (SPVACs) and single package vertical heat pumps (SPVHPs), collectively referred to as single package vertical units (SPVUs). The Energy Policy and Conservation Act (EPCA) prescribes standards for various consumer products and certain commercial and industrial equipment, including SPVUs. EPCA also requires DOE to periodically review standards. In this NOPR; NOPD, DOE proposes to amend the current standards for SPVUs such that the existing standard levels would be based on a new cooling efficiency metric of Integrated Energy Efficiency Ratio (IEER) for SPVACs and SPVHPs, and the current heating efficiency metric of Coefficient of Performance (COP) for SPVHPs (but without any increase in stringency), In addition, DOE has initially determined that more-stringent standards for SPVUs would not be economically justified and would not result in a significant conservation of energy. DOE also announces a public meeting to receive comment on these proposed standards and associated analyses and results.

  • DOE will accept comments, data, and information regarding this NOPR; NOPD until February 6, 2023. 
  • Interested persons may submit comments identified by docket number EERE–2019–BT–STD-0033, by email (SPVU2019STD@ee.doe.gov), Federal eRulemaking portal (http://www.regulations.gov).
  • DOE will hold a webinar on Monday, January, 9th, 2023, from 1:00 p.m. to 4:00 p.m.
  • Click here to register for the webinar.
  • Foreign Nationals interested in participating in this webinar, must be screened by DOE Headquarters Security prior to being granted access. Please email Regina.Washington@ee.doe.gov to complete the necessary documentation at least two weeks prior to scheduled meeting date.
  • Additional webinar registration information, participant instructions, and information about the capabilities available to webinar participants will be published on DOE’s website: https://energy.gov/eere/buildings/public-meetings-and-comment-deadlines

DOE has published a Federal Register final rule amending its test procedures for single package vertical air conditioners and single package vertical heat pumps (SPVUs). DOE is incorporating by reference the most recent version of the relevant industry test standard, AHRI 390-2021, and amending certain provisions for representations for SPVUs. DOE is also establishing definitions for “single-phase single package vertical air conditioners with cooling capacity less than 65,000 Btu/h” and for “single-phase single package vertical heat pumps with cooling capacity less than 65,000 Btu/h” to distinguish such equipment from certain residential central air conditioners and heat pumps.

  • The effective date of this rule is January 6, 2023.
  • The final rule changes will be mandatory for product testing starting December 4, 2023.
  • The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register January 6, 2023.

For the latest information on the planned timing of future DOE regulatory milestones, see the current Office of Management and Budget Unified Agenda of Regulatory and Deregulatory Actions. All planned dates are preliminary and subject to change.

Current Standard

Single package vertical air conditioners and heat pumps manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(16), must meet the energy conservation standards specified in the Code of Federal Regulations at 10 CFR 431.97.


Current Test Procedure

To determine that single package vertical air conditioners and heat pumps that are currently manufactured or distributed into commerce are in compliance with DOE standards, manufacturers must follow the test procedure methods specified at 10 CFR 431.96.


Helpful Links

Compliance

DOE has established regulations on certification, compliance, and enforcement in the CFR at 10 CFR Part 429.  These regulations cover statistical sampling plans, certified ratings, certification reports, record retention, and enforcement.  More information on these regulations is available here.
