The largest Envo ducted head certifies at 19.5 SEER2 and 9 HSPF2, with 22,000 BTU cooling and 24,000 heating, rated to -22F. That 19.5 is the weakest certificate in this batch, tied with the Vireo equivalent.

The Sapphire version of this same head certifies at 22 SEER2 - two and a half points better. At 24,000 BTU running daily, that is the single widest efficiency gap in the GREE range and the clearest case for spending up. If the budget will not stretch, consider whether a cassette could be used instead.

Alternatives

Availability and price context

We could not verify a current retail price for this model. This model is sold through dealers, so we link to contractor quotes rather than a retail price.

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.
Authorized channel
GREE distributor path for distributor purchases; GREE online warranty claim form for equipment purchased online, Home Depot, or Lowes; GREE Select dealer installation and registration for the 10-year extended warranty.

GREE online purchases have a manufacturer-published warranty path, but buyers should keep purchase and installation documents and use a licensed HVAC contractor for diagnosis and claims.

Review methodology

Model context

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

Strengths

  • 24,000 BTU of heating, completely concealed, with a -22F low-ambient rating.
  • Covers a large area from a single hidden head.

Weaknesses

  • 19.5 SEER2 is the weakest certificate in this GREE batch.
  • Two and a half points behind the Sapphire version of the same head.
  • Cooling is 22,000 BTU, not 24,000; and a low-static head at this size has no design margin.

Frequently asked questions

Can I install the GREE Envo R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / ENV24HP230V1R32AO) myself, or do I need a pro?
GREE Envo R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / ENV24HP230V1R32AO) 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 Envo R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / ENV24HP230V1R32AO) keep heating in a cold winter?
The manufacturer publishes 19,600 BTU/h of heating output 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 Envo R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / ENV24HP230V1R32AO) need?
Published electrical requirements: 230 V voltage, 22 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, and the included line set comes pre-charged for 25 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
What warranty does the GREE Envo R32 24,000 BTU Concealed Ducted R-32 208/230V (DUC24HP230V1R32AH / ENV24HP230V1R32AO) carry?
The manufacturer publishes these warranty tiers: Standard: 5 yr parts / 7 yr compressor (eligible residential system). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
