Signs of compressor problems: unit not reaching temperature despite running constantly, compressor making loud knocking or grinding sounds, compressor starting and stopping rapidly (short cycling), compressor not starting at all, or high pressure shutdowns. Compressor failure is typically the most expensive refrigeration repair. Early diagnosis can sometimes allow for less costly repairs — don't wait if you hear unusual compressor noises.

Installation time varies significantly: single appliance with existing connections 2-4 hours; single appliance requiring new utility connections 4-8 hours; full kitchen buildout 1-3 weeks depending on scope, permit timelines, and contractor scheduling. Work with your installer to create a realistic timeline that accounts for utility work, inspections, and health department walkthroughs before opening.

Commercial refrigerators must maintain 40°F (4°C) or below for food safety compliance. Walk-in freezers should be at 0°F (-18°C) or below. Many food safety programs require refrigerators to run at 35-38°F for proper margin. If your unit struggles to maintain proper temperature, especially during busy service periods or in hot kitchen environments, call a technician — compressor capacity or refrigerant levels may be the issue.
