Hello, kind of hard not being there but if a tensioner did not correct the tensioner noise with Ac on? then the AC system/compressor is likely under a load. This means the compressor is straining and will cause the tensioner to bounce /jump or make noise. I too lean to compressor BUT when you do a compressor, you always want to change the accumulator, That item is a filter and when opened to outside air, it gets contaminated. oil? you drain the oil from old compressor and if less than 2 oz? add oil to make 2 oz back into new compressor. Accumulator? you add 2 oz of new oil to it. The system takes 2 lbs of R 134
