Systems We Service

• Gree walk‑in coolers and freezers
• Reach‑in refrigerators and freezers
• Display and merchandiser cases
• Prep tables and line coolers
• Undercounter units and bar refrigeration
• Ice machines and condensers

From intermittent temperature swings to complete compressor or control failures, we diagnose the full system—refrigeration circuit, airflow, controls, electrical, and insulation envelope—to restore stable, uniform cooling.

Our Repair Process

• Intake and stabilization: We triage product risk and stabilize temps where possible.
• OEM‑based diagnostics: Measure pressures, superheat/subcool, amp draw, and verify control logic and sensors against specifications.
• Root‑cause confirmation: Leak check, airflow assessment, coil condition, defrost verification, and electrical integrity testing.
• Precise repair: Replace or reclaim refrigerant per best practices, repair leaks, restore controls, clear drains, and recalibrate setpoints.
• Performance verification: Hold‑temperature test and documentation so you can pass internal checks and health inspections.

Our goal: a durable fix that reduces energy waste, eliminates nuisance alarms, and prevents product loss—especially during peak load and hot Fontana afternoons.

Preventive Maintenance That Pays Back

Proactive care dramatically extends equipment life and reliability. We tailor Gree maintenance plans to your load profile and hours of operation.

• Coil cleaning, airflow optimization, and door gasket inspection
• Defrost system checks and condensate management
• Electrical tightening and component testing
• Refrigerant circuit health checks and leak surveys
• Setpoint, sensor, and controller calibration

You get fewer breakdowns, steadier temperatures, lower kWh per pound of product, and cleaner audits.

Industries We Support

• Restaurants, bars, and coffee concepts
• Grocery, markets, and convenience stores
• Distribution centers and cold storage
• Food manufacturing and commissaries
• Healthcare, education, and corporate facilities

Whether it’s a single reach‑in or a multi‑unit cold chain, our engineering‑driven approach scales to complex commercial demands.

Common Issues We Resolve

• Warm cases, icing coils, short cycling, or nuisance high‑temp alarms
• Door gasket failures and infiltration leading to frost and energy waste
• Compressor, fan, or control board failures
• Drain clogs, water on floors, and sanitation hazards
• Uneven temperatures across bays or shelves

We fix the immediate problem and address the underlying cause so you don’t see the same failure twice.
