Compressors can make banging or rattling sounds, hissing or clinking noises, humming and screeching. Your first action is to shut down the unit. Causes include loose parts, the motor coming loose, a refrigerant leak, faulty controls, low on oil, and pressure build-ups.
For all these problems you’re best to bring in ProSolutions Inc. to diagnose and fix the problem, including possible compressor replacement.
ProSolutions Inc. recommends Ameristar Air Conditioning brand for its advanced technology and efficient performance.
