Our Diagnostic Process

We don’t guess — we measure and prove. Our engineers perform a structured diagnostic that includes:
• Electrical testing under load (voltage drop, amp draw, insulation checks)
• Refrigeration readings (suction/discharge, superheat, subcooling, saturation temps)
• Airflow and heat load verification
• Leak detection and moisture/acidity screening
• Control logic review, defrost programming, and sensor calibration
• Visual inspection for oil traces, corrosion, and sanitation compliance

Every repair is documented with before/after readings so you know your York system is back within spec.

Engineered Quality You Can Feel

Our family has 80+ years in engineering across four generations. Team members train at manufacturer facilities including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That rigorous foundation shows in our refrigeration work — clean brazing, correct evacuation and dehydration, precision charging, and control tuning that improves stability and efficiency. We excel at complex jobs others avoid, from multi‑evaporator balance issues to intermittent electrical faults.

Food Safety, Compliance, and Clean Work

Protecting your inventory and guests comes first. We prioritize temperature recovery, sanitize work areas, and set defrost/airflow to reduce moisture and bacteria risks. Our methods align with health code best practices and industry standards for commercial refrigeration service, and we leave your site as clean as we found it.

Based in Southern California, we serve Los Angeles County and nearby regions — including Fontana and neighboring Inland Empire cities, Western Riverside County, Orange County, and Ventura County. We arrive with stocked service vehicles, quality parts, and the instruments required for on‑the‑spot repairs whenever possible.

Preventive Maintenance That Pays Back

• Coil cleaning, drain clearing, and airflow optimization
