★★★★★

“Same day Sub-Zero repair — super professional”
Called in the morning when our Sub-Zero built-in refrigerator stopped cooling, and a technician arrived the same afternoon. He diagnosed a failed evaporator fan motor, had the genuine OEM part on the truck, and finished within the hour — professional from start to finish, no surprises.

Daniel W., Alpharetta
★★★★★

“honest service and real expertise”
Our Sub-Zero wine cooler started running warm overnight and we got an upfront flat-rate inspection before any work began. The licensed technician walked us through the failed compressor relay, the service matched the consultation exactly, and the warranty gave us real peace of mind.

CM
Catherine M., Alpharetta
★★★★★

“Fast, clean, and reliable service”
Our Sub-Zero ice maker stopped producing ice right before guests arrived. They were out within hours, swapped the failed water inlet valve with a genuine OEM part, and left the kitchen cleaner than they found it — truly impressive service.

AJ
Anthony J., Alpharetta
★★★★★

“Finally found a company I trust”
After a previous company couldn’t identify the issue, this team actually fixed our Sub-Zero freezer drawer on the first visit. Quick diagnosis of the burned-out defrost heater, same-day repair, and a genuinely professional attitude from arrival to cleanup — we won’t call anyone else.
