Commercial Refrigeration Repair in Rialto

When a walk-in warms up or a line cooler drifts out of range, every minute matters. #1 AC Guys blends rapid response with fourth-generation engineering rigor to get your commercial refrigeration back to setpoint—safely, efficiently, and with lasting results. We proudly serve Los Angeles County and nearby areas, routinely supporting commercial clients in Rialto and the surrounding Inland Empire.

What We Repair and Optimize

• Walk-in coolers and freezers: temperature stabilization, defrost performance, door heaters, gaskets, and thresholds
• Reach-in refrigerators and freezers, prep tables, chef bases, and undercounters
• Display cases and merchandisers (open air and glass-door)
• Ice machines (cubes, flake, nugget) and bin sanitation
• Refrigeration controls: thermostats, sensors, EEVs/TXVs, controllers, and monitoring
• Compressors, condensers, evaporators, fan motors, and airflow management
• Refrigerant leaks, recovery, charging, and superheat/subcool tuning

We service most major commercial makes and models. Our technicians are EPA 608–certified and follow best practices for recovery, handling, and documentation.

AC PRO-Compatible Sourcing for Speed

Uptime is everything. To shorten lead times, we leverage AC PRO supply channels for OEM-grade and compatible components—motors, contactors, capacitors, fan blades, filters, and controls—so your equipment is repaired faster with the right parts. Our goal: fewer callbacks, stable product temperatures, and predictable operating costs.

The Engineering Difference

Our family has 80+ years of cumulative engineering experience, and we bring that depth to every service call. #1 AC Guys’ technicians have trained with manufacturers at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That background shapes our process: we verify load conditions, airflow, refrigerant circuit health, defrost logic, and controls before recommending repairs. The result is accurate diagnostics that address causes, not just symptoms.

Rapid Response in Rialto

From restaurant rushes to market restocks, we understand the rhythms of your business.
• Same-day diagnostics, when available
• Emergency repair availability to protect perishable inventory
• Clear ETAs and proactive communication
• Technicians equipped to resolve the most common issues on the first visit

Preventive Maintenance That Pays Back

Unplanned failures are costly. Our commercial refrigeration maintenance programs reduce risk and energy waste.

• Coil cleaning and case airflow balancing for faster pull-down and lower kWh
• Gasket inspection and door alignment to eliminate warm-air infiltration
• Drain and pan sanitation to prevent odors and health-code issues
• Electrical and control checks to catch weak components early
• Refrigerant leak screening and performance baselining (amps, superheat, subcool)
• Defrost schedule optimization for stable case temperatures

Every visit includes a written report with prioritized recommendations, so you can plan repairs and budgets with confidence.

Health, Safety, and Compliance

Food safety and air quality are central to our mission of healthy indoor environments. We calibrate sensing, verify case temperatures, and restore reliable defrost and drainage. Technicians follow manufacturer service procedures and safety protocols, including lockout/tagout and proper refrigerant recovery, to protect your team and facility.

Transparent Pricing and Strong Warranties

No surprises. You get clear, line-item estimates before work begins, options when possible, and workmanship warranties we stand behind. We can also document repairs for insurer or landlord requirements.
