Any thoughts on whether AMEX PRG extended warranty would apply to a new home air conditioner?

The warranty description of coverage notes "business fixtures" are excluded, and lists air conditioners as one example of this. However, this would be a home A/C unit, not one for a business, so I'm not sure if the exclusion is applicable. That section also lists refrigerators as an excluded item, but post 114 indicates this item was covered, presumably for a home unit.
