Unedited reviews from Sub-Zero owners across the Bay Area. Named technicians, real repairs, real results.
"Freezer now produces ice. Very knowledgeable and professional."
Our Sub-Zero refrigerator and freezer stopped producing ice. I called Winline and they sent a technician the next day. He identified one defective part, ordered it, and installed it the next day. Highly recommend.
"I now have basically a new Sub-Zero refrigerator/freezer."
Sub-Zero ice cube door was frozen open. The senior technician replaced the defective part, identified and replaced a defective door switch, and also cleaned the condenser and compressor. Thank you Winline!
"Conscientious, dedicated, knowledgeable. Highly recommend."
The refrigerator needed to be repaired and the technician replaced the control board. However, it stopped again, and he returned and continued to work on it until he found the real problem.
