UL2-40 Transition and Amana-Goodman Air Handlers

by HVAC Distributors

The UL standard governing electric heat kits in air handlers are changing on January 1, 2024. This will cause a change to the equipment and to the electric heat kits. The new standard is UL Standard 60335 2-40 (short name “UL2-40”).

AHVE, AMVE, AMVT, and AMST Air Handlers:

  • All air handlers manufactured after December 31, 2023 must comply with UL2-40.
  • Air handlers made before December 31, 2023 can still be sold after.
  • The new UL2-40 compliant air handlers are only compatible with the new UL2-40 compliant electric heat kits.

ACSF, AWSF, and AWST Air Handlers:

  • These are also affected by the new requirement, but they come with the heat kit factory-installed, so new part numbers are not needed.

MBVC Blowers:

  • These are affected by the new requirement and there will be new model numbers for the new blowers (TBA).

What to Keep in Mind About AHRI Ratings:

  • The AHRI-rated performance is not affected by this change.
  • Daikin lists the air handlers with the major rev, so the AHRI rating numbers will change.
  • The Amana-Goodman Equipment Selector will be updated as the information becomes available from Daikin.
