I submitted a request to replace one AC Infinity fan on Saturday. I sent them four order numbers (two from Amazon, two from ACI) and explained that I didn’t know which order was used to purchase the one loud fan. As KGBSkunky also experienced, AC Infinity in turn decided to replace all fans and is shipping FOUR fans to replace all of my old oscillating fans. Apparently they’ve upgraded the motor and gears for longer life. (They claim that a larger brushless EC motor with carbon steel gears and IP44 rating is redesigned to maximize oscillation lifespan)
I didn’t have to send invoices…..I simply provided order numbers.
Thanks again to
@KGBSkunky for sharing this information!
