2007 Ford Fusion Chirping noise from passenger side

Noises problem
2007 Ford Fusion 4 cyl Automatic 52,000 miles

Some mornings at start-up my Fusion makes a QUICK chirping or screech noise (like crickets) its not a constantly noise it just does it real quick and that is it. Sometimes if I let it set for a while maybe 5 or 6 hours it will do it also. This same cricket noise I get from passenger side I hear it also when I turn my ac on and shift my car from park to reverse its a little worse like screech. Screech, I hear it like 2 times kind of a short not quick chirp, if I put it back in park I do not hear it. I hear this same exact nosie when AC is on or off BUT worse when its on. It does not do it constantly while its on just at the very beginning sometimes you can hear it squeaking as its turning, So Far I have replace my Serpentine belt and no luck still the same problems, what could be causing this my pulleys? Please help me out here< I don't want to take it to the ford dealership when I can maybe get it fixed cheaper. I have never had the idler or tensioner pulley replaced, I just bought both of them but not sure if that is the problem.
