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+ Ultra 36,000 BTU R-410A 208/230V (VIRU36HP230V1AH / VIRU36HP230V1AO) myself, or do I need a pro?
GREE Vireo+ Ultra 36,000 BTU R-410A 208/230V (VIRU36HP230V1AH / VIRU36HP230V1AO) 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+ Ultra 36,000 BTU R-410A 208/230V (VIRU36HP230V1AH / VIRU36HP230V1AO) keep heating in a cold winter?
The manufacturer publishes 34,000 BTU/h of heating output at 5F. Rated heating operation extends down to -31 F. Certified heating efficiency is 8.5 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+ Ultra 36,000 BTU R-410A 208/230V (VIRU36HP230V1AH / VIRU36HP230V1AO) need?
Published electrical requirements: 230 V voltage, 30 A minimum circuit ampacity, and 50 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 165 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+ Ultra 36,000 BTU R-410A 208/230V (VIRU36HP230V1AH / VIRU36HP230V1AO) 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.
