Light buzzing squeeling noise

Hi, I just had my belt tensioners and belts replaced. Everytime I start up the car I hear a slight buzzing/squeeling noise. This noise also happens at idle too. Is this possibly the belt tensioners? Are they too tight and need to be adjusted? The other thing I was thinking that it could be the alternator failing but a voltage test was run and all checked out ok. But if the coils in the alternator are failing it may be making the noise. Anyone any inputs on tweeking or adjusting the tensioners? Or could it be the belts themselves?
