Commercial Refrigeration Repair in Fontana, CA

Protect your inventory, safeguard food safety, and restore business continuity with #1 AC Guys—Fontana’s go‑to engineering team for Commercial Refrigeration Repair. We specialize in complex diagnostics and durable fixes for restaurants, supermarkets, convenience stores, hospitality, pharmaceutical/medical cold storage, and distribution. From erratic temperatures to compressor short‑cycling, icing, fan failures, and controller faults, our engineers resolve issues at the root cause to extend equipment life and reduce energy waste.

Systems We Service

• Walk‑in coolers and walk‑in freezers
• Reach‑in coolers/freezers and prep tables
• Supermarket and convenience store display cases
• Ice machines and storage bins
• Glycol and process chillers
• Beer caves, beverage systems, and specialty cold rooms

Our approach starts with a thorough site assessment: airflow and load analysis, electrical and control checks, refrigerant circuit testing, and verification of defrost, door heaters, and case controllers. We document findings and explain options clearly so you can choose the best path—repair, component upgrade, or strategic retrofit.

Engineered Repairs That Last

As a 4th‑generation family of engineers with 80+ years in engineering, we apply rigorous standards to every repair. Expect clean brazing, proper evacuation and dehydration procedures, accurate charge by weight and superheat/subcooling validation, verified airflow and case balance, and calibrated controls. We focus on restoring factory performance and preventing repeat issues—saving you time, stress, and money.

Parts, Brands, and Supply Readiness

We maintain strong local sourcing to minimize downtime, including OEM‑grade components available through trusted distributors such as AC PRO. Whether you operate equipment supplied by AC PRO or other major supply channels, we ensure fast access to compatible parts and materials. Our team has factory training from Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), bringing manufacturer‑level insight to field service across diverse commercial applications.

Common Issues We Resolve

• Temperature swings, product loss, and nuisance alarms
• Compressor failures, head pressure issues, and oil return problems
• Evaporator icing, defrost failures, and blocked drains
• ECM/PSC fan motor failures and airflow imbalance
• TXV/EEV malfunctions, refrigerant leaks, and moisture contamination
• Control board faults, sensor errors, and case lighting/heater issues

We also tackle energy efficiency upgrades—ECM fan retrofits, case door gaskets/sweeps, anti‑sweat control optimization, floating head/low‑condensing strategies, and smart monitoring—so your system runs colder, cleaner, and cheaper.
