Saw this apparently ridiculous statement from Airbnb on social media today,
A fan legally constitutes an air conditioner
It's unclear by what law that might be the case - the situation took place in Mexico, and Airbnb is a US company. What I managed to find is Definitions concerning commercial air conditioners and heat pumps, which doesn't concern fans, and that "The [air conditioning] term excludes window units" (which suggests that a fan is in no way an A/C unit).
However, my experience at large companies suggests that support agents are trained to not make risky statements involving legal matters, so is there some legal ground for a fan to be considered an air conditioning unit?
