GREE / Vireo R32
GREE Vireo 18k Concealed Ducted R-32 208/230V Mini-Split
At 18,000 BTU the Vireo ducted head certifies at 22.5 SEER2 and 9 HSPF2 - notably better than the 12k version of the same head, which is the opposite of the usual pattern. If you are already committed to a ducted install at roughly this size, that makes this one of the better-value points in the range.
It is still a low-static unit. Eighteen thousand BTU tempts people into feeding three or four rooms from one head, and that is where these installations go wrong. Keep the runs short and balanced, or accept that the certificate on paper will not be the performance in the house.

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 Vireo R32 18,000 BTU Concealed Ducted R-32 208/230V (DUC18HP230V1R32AH / VIR18HP230V1R32AO) myself, or do I need a pro?
- GREE Vireo R32 18,000 BTU Concealed Ducted R-32 208/230V (DUC18HP230V1R32AH / VIR18HP230V1R32AO) 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 Vireo R32 18,000 BTU Concealed Ducted R-32 208/230V (DUC18HP230V1R32AH / VIR18HP230V1R32AO) keep heating in a cold winter?
- The manufacturer publishes 15,000 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 Vireo R32 18,000 BTU Concealed Ducted R-32 208/230V (DUC18HP230V1R32AH / VIR18HP230V1R32AO) need?
- Published electrical requirements: 230 V voltage, 16 A minimum circuit ampacity, and 20 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 Vireo R32 18,000 BTU Concealed Ducted R-32 208/230V (DUC18HP230V1R32AH / VIR18HP230V1R32AO) 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.
