Our Sub-Zero refrigerator was not working when we called. The technician arrived the next morning in Dunwoody Village, traced the issue to failing condenser fan motor, and replaced it with a genuine Sub-Zero part. The full job took under two hours with thorough testing before he left. Highly recommend.

We noticed Sabbath mode or demo mode stuck on on our Sub-Zero refrigerator after a long weekend in Perimeter Center. This team ran a full diagnostic and confirmed damaged ribbon cable from door to body. They installed an OEM component and the unit has worked flawlessly since. Respectful of our home, clear communication throughout.

Two other companies couldn't fix our Sub-Zero refrigerator that was not working. The technician identified torn or cracked rubber seal on the first visit in Winters Chapel, replaced the part the same day, and walked us through the warranty. Punctual and clearly experienced with Sub-Zero units.

Scheduling was simple online and they kept me updated until arrival in Mount Vernon Forest. My Sub-Zero refrigerator had freezer too cold, fridge too warm that turned out to be airflow blockage from overstuffed shelves. The technician used Sub-Zero-approved parts and explained the fix clearly. Best appliance service we've had in Dunwoody.
