Don was very conversant about the repairs and is obviously very capable. I appreciated his approach and the work was done very well. We are pleased that you offered service for our Sub-Zero refrigerator. It is 24 yrs. old and now is "still" going strong. Don is the type of technician we want in our home. Trustworthy, knowledgeable and pleasant. Will definitely recommend Northgate to our friends in the area.
