Air Innovations shall provide a three (3) year extended warranty (5 years total) on the Wine Guardian compressor ONLY. Warranty covers the cost of a new replacement compressor should the "born with" Wine Guardian compressor be deemed defective anytime during the three (3) year extension. Warranty covers the cost of a new compressor, which must be supplied by Air Innovations. All shipping and labor charges for replacement of the new compressor are not covered under this extended warranty. The Wine Guardian "born with" compressor must be returned to Air Innovations as proof of compressor replacement. Effective date for any extended warranty is the original invoice date for the Wine Guardian unit, not the purchase date of the extended warranty.
