Compressor growling noise

I have 2 ac units 410a. One is 3.5 ton and the other is 4 ton. 3.5 ton cools the farther end of the house. This unit growls always when it starts, and on and off when it runs. The 4 ton unit doesn't make the noise at all. There is a sight glass in the discharge line of the noisy unit. The growling noise is associated with lots of bubbles. It cools the house. (house set 78 deg, vent 65 deg). Why the noise? And do I need to call a professional? Thank you.

Since both aren't growling, there is an issue. I would get a qualified HVAC person to look at it.
