This noise is loud and happens on and off. I had the same problem last year. The issue is air in the copper water line (from garage to roof). I drain the unit and recharge with water then the hammer noise goes away temporarily.
This unit is only 1 year old and generally works like a charm.
I'm not much of a DIY but would like to avoid a service call. It wakes me at night.
