ave this unit installed Feb. 2007,, all indications are low on refrigerant. R 404 a unit, service stubs so removed charge installed tube type access fittings on the stubs,,,weighed in an exact charge, monitored the unit pulldow lasat night. Tonight she calls me at 9:00 and tells me that the box is forty degrees. I had her remove all o9f the product from the unit and turn it off. Yesterday. when I was there I checked for leaks in all accessable regrigeration piping etc.
What do I do to gain access to the evaporator? Do you repair this equipment, or just condemn it?
