The largest Sapphire ducted head certifies at 22 SEER2 and 9 HSPF2, with 22,000 BTU cooling and 24,000 heating, rated to -22F. Against the Vireo version of the same size - which manages only 19.5 SEER2 - this is a two-and-a-half point gain, the widest Sapphire margin anywhere in the ducted and cassette range.

That gap matters because a 24k unit runs a lot of hours. If the install has to be concealed at this capacity, this is clearly the one to buy rather than the Vireo.

Purchase channel policy

GREE publishes an online/retail warranty-claim path for equipment purchased online, Home Depot, or Lowes rather than treating online purchase as a warranty voidance.

Warranty impact
Online purchase changes the claim path: routine parts use GREE's online claim form, while compressor failures and refrigerant leaks require tech-support confirmation before the online claim.
Installation condition
Warranty claims for online/retail purchases must be completed by a contractor after an on-site diagnosis, with required documentation such as purchase receipt or installation invoice and data-plate photos.

Structured ratings
Certification: ENERGY STAR certified. Refrigerant: current low-GWP R-32. Minimum heating ambient: -22 F.

Strengths

  • 22 SEER2 against 19.5 for the Vireo equivalent - the widest Sapphire advantage in this range.
  • 24,000 BTU of heating, completely concealed.

Weaknesses

  • Cooling is 22,000 BTU, not the 24,000 implied by the badge.
  • A low-static head at this capacity has very little margin for duct design error.
  • Concealed filter and coil access makes neglect easy.

Frequently asked questions

Can I install the GREE Sapphire R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / SAP24HP230V1R32AO) myself, or do I need a pro?
GREE Sapphire R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / SAP24HP230V1R32AO) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
Will the GREE Sapphire R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / SAP24HP230V1R32AO) keep heating in a cold winter?
The AHRI/ENERGY STAR certification lists 21,000 BTU/h of heating capacity at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 9 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
What electrical circuit does the GREE Sapphire R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / SAP24HP230V1R32AO) need?
Published electrical requirements: 230 V voltage, 25.5 A minimum circuit ampacity, and 30 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
How far can the outdoor unit be from the indoor head?
The published maximum line-set length is 131 ft. The outdoor unit's factory charge covers up to 25 ft of line; longer runs need added refrigerant. Measure the planned routing before ordering.
What warranty does the GREE Sapphire R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / SAP24HP230V1R32AO) carry?
The manufacturer publishes these warranty tiers: Base: 5 yr parts / 7 yr compressor (eligible residential system). Score uses Base.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
