The Envo slim-duct head at 9,000 BTU certifies at 22 SEER2 and 9.2 HSPF2, rated to -22F, with 9,100 BTU cooling and 10,500 heating. It disappears above a ceiling or into a soffit and feeds a register, leaving nothing visible in the room.

It certifies identically to the Vireo version and only 0.3 behind the Sapphire, so the line choice barely matters here. What does matter is duct design - this is a low-static head, and a long or unbalanced run will cost far more performance than any difference between GREE's condensers.

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.

Strengths

  • Completely concealed; only a supply grille is visible.
  • 9.2 HSPF2 with a -22F low-ambient rating.
  • Can serve two small adjacent rooms where the layout allows.

Weaknesses

  • Low static pressure - short, well-designed runs only.
  • Concealed filter access makes neglected servicing likely.
  • Quote-only; no verified retail listing.

Frequently asked questions

Can I install the GREE Envo R32 9,000 BTU Concealed Ducted R-32 208/230V (DUC09HP230V1R32AH / ENV09HP230V1R32AO) myself, or do I need a pro?
GREE Envo R32 9,000 BTU Concealed Ducted R-32 208/230V (DUC09HP230V1R32AH / ENV09HP230V1R32AO) 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 9,000 BTU Concealed Ducted R-32 208/230V (DUC09HP230V1R32AH / ENV09HP230V1R32AO) keep heating in a cold winter?
The manufacturer publishes 9,500 BTU/h of heating output at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 9.2 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 9,000 BTU Concealed Ducted R-32 208/230V (DUC09HP230V1R32AH / ENV09HP230V1R32AO) need?
Published electrical requirements: 230 V voltage, 10 A minimum circuit ampacity, and 15 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 66 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 9,000 BTU Concealed Ducted R-32 208/230V (DUC09HP230V1R32AH / ENV09HP230V1R32AO) 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.
