Whistling Trane Air Conditioner System

Ac-Appliance Pros of Richardson, Texas installed two Trane A/C systems in the Spring of 2007. The compressor for one of the two systems often emits a high-pitched whistle when the system is running. This happens multiple times per day. This whistle was present the day the systems were installed, and has continued ever since. Ac-Appliance Pros has not been able to resolve this problem.
