My mechanic said I needed to have them replaced and I'm just wondering if this could be causing my heat inside the car to be going in and out and my temp gauge to be rising and falling a bit.

Is this right?
no, you probably have an air bubble in the system. webracin explained how to fix that. Take a pic of the hoses and post them, we'll tell you if they're good.
