Our Sub-Zero freezer was not cooling when we called. The technician arrived the next morning in Kennesaw Mountain area, traced the issue to loose internal tubing, 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 moisture on the exterior cabinet on our Sub-Zero freezer after a long weekend in Roswell Road corridor. This team ran a full diagnostic and confirmed unlevel installation tipping unit forward. They installed an OEM component and the unit has worked flawlessly since. Respectful of our home, clear communication throughout.

Built-In Sub-Zero Freezer Repair
★★★★★
Two other companies couldn't fix our Sub-Zero freezer that was not cooling. The technician identified blocked drain line preventing meltwater removal on the first visit in Marietta Square, replaced the part the same day, and walked us through the warranty. Punctual and clearly experienced with Sub-Zero units.

Sub-Zero Freezer Column Service
★★★★★
Scheduling was simple online and they kept me updated until arrival in East Cobb. My Sub-Zero freezer had evaporator coils only partially cold that turned out to be capillary tube partial blockage. The technician used Sub-Zero-approved parts and explained the fix clearly. Best appliance service we've had in Marietta.
