AHRI 1340 (I-P): Performance Rating of Commercial and Industrial Unitary Air-conditioning and Heat Pump Equipment

Standard Scope

This standard establishes definitions, classifications, test requirements, rating requirements, minimum data requirements for published ratings, operating requirements, marking and nameplate data, and conformance conditions that include the IVEC and IVHE efficiency metrics for commercial and industrial unitary air-conditioning and heat pump equipment.

AHRI 1340 applies to factory-made commercial and industrial unitary air-conditioning and heat pump equipment as defined in Section 3. This standard applies only to electrically operated, vapor compression refrigeration systems.

Note: Units can include furnaces that can be used for building heating and as auxiliary heat for heat pumps.


AHRI 1340 does not apply to the following:

  • Commercial and industrial unitary air-conditioning condensing units with a capacity greater than 135,000 Btu/h as defined in AHRI 365 (I-P)

    Note: Condensing units with a capacity ≤135,000 Btu/h are rated as a matched system with fan coil or air handler.

  • Performance of fan coil units rated in accordance with AHRI 440 (I-P) or AHRI 441 (SI)

  • Air-cooled unitary air-conditioners and unitary heat pumps as defined in AHRI 210/240-2023 (2020), with capacities less than 65,000 Btu/h

  • Water-source heat pumps as defined in ASHRAE/AHRI/ISO 13256-1 and AHRI 600 (I-P)

  • Variable refrigerant flow air-conditioners and heat pumps as defined in AHRI 1230 (I-P)

  • Rating of units equipped with desuperheater/water heating devices (as defined in AHRI 470) in operation

  • Units with adiabatically pre-cooled condensers
