Narrative:

While approaching the gate the number 1 engine came in contact with a cart that was parked in the 'operational safety zone.' as I approached the stop point following the guideman's instructions I notice another person standing beside him gesturing wildly and pointing to the left wing. Based on this I stopped the aircraft. Approximately 5 seconds later the guideman directed that I stop the aircraft. By this time the parking brake was set.we ran the parking checklist and then I went outside to see what the issue was; at this point I noted that the #1 engine had hit the air conditioning cart. I also noted that the nose wheel was short of the stop line. If I had followed the guideman's instructions I would have pushed the cart about 18 inches to reach the stop line.the reason that I stopped the aircraft was because of the concerned expression and gestures of a [company] employee that was observing the parking operation not because I was directed to by the lead marshaller. I believe that the lead marshaller was focused on the nose wheel and not looking at the other guide men or the entirety of the aircraft.
