    Confused Suction Line Noise & Shaking

    I have a 2-1/2 ton Carrier whole house a/c system about 8-9 years old. Recently the suction line has started making a high pitched noise and the whole line will start shaking. This is heard & is visible in the basement from the furnace to the exit point in the foundation where the lines go outside. It doesn't do this each time the a/c runs. Can anyone tell me what might be causing this and do I have a problem I might try to fix or do I need a pro?

    Could be related to a problem in the outdoor unit. The best thing to do to prevent more issues is call a reputable service company.
