Get matched with a licensed proRefrigeration in Sylmar serves walk-in coolers, commercial kitchens and industrial plants — not the same as residential HVAC even when both use refrigerant. EPA certification for handling refrigerants is separate from the state licence.
Equipment selection ties to electrical service and ventilation. A contractor who sizes only the box, not the heat rejection path, creates short cycling and high power bills.
Walk-in panels ship knocked down and need square rooms. Measure diagonals before ordering — out-of-square walls produce gasket gaps that frost the floor.
Class C-38 (Refrigeration) is refrigeration — CSLB authorizes installation and repair of refrigeration systems. Residential air conditioning is usually Class C-20 unless the scope is commercial refrigeration equipment. Remote condensers on rooftops need structural and electrical coordination that is easy to forget on small commercial jobs.
Contractors hold an active Class C-38 (Refrigeration) licence at a Sylmar address. Commercial installs often need mechanical permits through LADBS. Condensate drains from coolers must route to an approved receptor, not across a walkway where ice can form. Log case temperatures for a week after startup because commissioning proves performance before product goes in.
The register does not record EPA Section 608 credentials. Ask for technician certification before anyone vents refrigerant. Defrost cycles on walk-in evaporators must be programmed for the product load, or ice builds on coils and warm spots appear.
Night covers on open display cases save energy in grocery retrofits. Ask whether operating cost estimates include covers and anti-sweat heaters.

Licence first. References second. Reviews last. Why that order.
Get matched with a licensed proClass C-38 (Refrigeration) covers refrigeration systems. Comfort cooling in homes is typically Class C-20. A restaurant project may need both.

Mechanical and electrical permits are common for commercial refrigeration through LADBS. The contractor should list submittals in the schedule.
Manufacturer maintenance intervals apply. Dirty coils raise energy use long before the equipment fails.
Sound ratings and placement relative to bedrooms matter. Ask for decibel data and a suggested pad location before equipment is ordered.
