The largest Envo cassette certifies at 22.5 SEER2 and 9 HSPF2, with 22,000 BTU cooling and 24,000 heating, rated to -22F. It is half a point behind the Sapphire version and identical to the Vireo.

As with every 24k in this range, the badge describes the heating figure. Size on the 22,000 BTU cooling number if you are in a cooling-dominated climate, and budget for the install as seriously as the equipment - ceiling structure and return path drive the cost at this size.

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.

Frequently asked questions

Can I install the GREE Envo R32 24,000 BTU Four-Way Ceiling Cassette R-32 208/230V (CAS24HP230V1R32AH / ENV24HP230V1R32AO) myself, or do I need a pro?
GREE Envo R32 24,000 BTU Four-Way Ceiling Cassette R-32 208/230V (CAS24HP230V1R32AH / 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 Four-Way Ceiling Cassette R-32 208/230V (CAS24HP230V1R32AH / ENV24HP230V1R32AO) keep heating in a cold winter?
The manufacturer publishes 16,800 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 Four-Way Ceiling Cassette R-32 208/230V (CAS24HP230V1R32AH / 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 Four-Way Ceiling Cassette R-32 208/230V (CAS24HP230V1R32AH / 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.
