Daikin Atmosphera Series SEER2 Update

Daikin Atmosphera Series SEER2 Update

by HVAC Distributors

Daikin is updating the Atmosphera Series mini-split heat pump to meet SEER2 requirements.

The Atmosphera has two updates:Daikin ATMOSPHERA Wall Mount | Daikin AC

  • The new models comply with the UL 60335 2-40 safety standard, which goes into effect January 1, 2024.
  • The new models are SEER2 rated.

Like the old Atmopshera models, the updated version has these same features:

  • Built-in Wi-Fi, eliminating the need for an external Wi-Fi Adaptor
  • Heating capacity at low ambient temperatures
  • In addition to heating and cooling modes, it also has a Dry mode, where the primary function is dehumidification.
  • A field-removable drain pan makes periodic maintenance easier and faster.
  • Pre-charged with more refrigerant (49.2 feet), reducing the need to add refrigerant in the field, making for faster installations.
  • Uses R-32 refrigerant, not R410a. Though R-32 has been in use for years on tens of thousands of systems outside the US, this is the first Daikin mini-split system in the US
    to use R-32.

Note: Daikin requires that a dealer who wants to purchase Atmosphera must be A2L-certified. We encourage the use of the certification class available on Daikin University or webinars offered through HVAC Distributors.


There is NO forward-backward compatibility between the old and new Atmosphera units.


HVAC Distributors will continue to stock the old Atmopshera models, then transition to the new models when inventory is depleted.
