Our customers in Alpharetta highlight attention to detail, accurate diagnostics, and reliable Sub-Zero freezer repairs that hold up for years.

★★★★★
Our Sub-Zero freezer started showing alarm sounding intermittently late one evening. The technician arrived the next morning in Halcyon, diagnosed refrigerant leak in sealed system, and replaced it with a genuine Sub-Zero part. The full job took under two hours, with thorough testing before he left. Highly recommend.

Built-In Sub-Zero Freezer Repair
★★★★★
We noticed condensation pooling at the bottom seal on our Sub-Zero freezer after a long weekend in Windward. This team ran a full diagnostic and traced the issue to failed defrost thermostat. They replaced the part with an OEM component, and the unit has worked flawlessly since. Respectful of our home, clear communication.

Samantha L., Alpharetta
Sub-Zero Freezer Column Service
★★★★★
Our Sub-Zero freezer kept showing compressor never shuts off after two other companies couldn't fix it. The technician identified fan motor running at reduced speed on the first visit, replaced it the same day in Country Club of Roswell border, and walked us through the warranty. Punctual, courteous, and clearly experienced with Sub-Zero units.

Integrated Sub-Zero Freezer Drawer Repair
★★★★★
Scheduling was simple online and they kept me updated until arrival in Avalon. My Sub-Zero freezer had loud buzz before compressor starts that turned out to be compressor mount wear creating vibration. The technician used Sub-Zero-approved parts and explained the fix in plain language. Best appliance service we've had in Alpharetta.
