The Program
Electrical Contractor for Cold Storage Facilities
Direct Source provides electrical contracting for cold storage and refrigerated warehouse facilities across Southern California — from the LA Basin through the Inland Empire and Orange County. Our work covers refrigeration electrical systems, classified area installations, motor and drive maintenance, MCC work, and preventive maintenance programs for cold storage operations.
Schedule: Scheduled refrigeration electrical PM and emergency response — 24/7.
Refrigeration Electrical
Compressor motor and drive electrical installation and maintenance, condenser fan motor and drive work, evaporator fan motor replacement, refrigeration panel and MCC maintenance, and ammonia system electrical.
We work on both ammonia (NH3) and HFC refrigeration systems — electrical and controls, not refrigerant.
Ammonia Classified Area Electrical
Class I Division 1 and Division 2 electrical installation for ammonia refrigeration facilities — explosion-proof motors, classified area panels, conduit systems, and NEC Article 501 compliance.
Ammonia machinery rooms and high-pressure receiver areas require classified electrical. We install and service them.
Compressor Motor & Drive PM
Refrigeration compressor motor insulation resistance testing, VFD inspection and cleaning, soft starter service, and compressor motor electrical PM for cold storage refrigeration systems.
Compressor motor PM catches winding degradation and drive issues before a compressor failure causes product loss.
MCC & Distribution
Cold storage MCC maintenance and upgrades, electrical distribution panel work, bus duct inspection, breaker replacement, and electrical distribution troubleshooting for refrigerated warehouses.
Cold storage facilities often have large electrical distribution systems serving multiple refrigeration circuits. We service them.
Refrigeration Controls & PLC
Refrigeration system controls troubleshooting, PLC and HMI support, sensor replacement, I/O troubleshooting, and control system maintenance for cold storage automation and monitoring systems.
Refrigeration controls failures can cause temperature excursions that damage product. We respond fast.
Emergency Electrical Response
24/7 emergency electrical response for cold storage facilities — compressor electrical failure, MCC fault, refrigeration panel trip, or any electrical issue that threatens refrigeration system uptime.
Cold storage electrical emergencies risk product loss in hours. Emergency response is prioritized.
Why Direct Source
What Makes Our Program Different
Ammonia and HFC system experience
We work on both ammonia and HFC refrigeration system electrical — compressor motors, condenser and evaporator fan drives, refrigeration panels, and classified area electrical. Refrigerant handling is separate, but we cover everything electrical.
Classified area certified electricians
Ammonia machinery rooms require Class I Division 1 or Division 2 electrical. Our electricians are trained and certified for classified area work in cold storage and refrigeration facilities.
24/7 emergency response
A refrigeration electrical failure is an emergency — product is at risk within hours. We provide 24/7 emergency electrical response for cold storage clients, and PM contract clients are prioritized.
Full SoCal coverage
LA Basin, Inland Empire, and Orange County — we serve cold storage and refrigerated warehouse facilities across all three Southern California markets.
Every Visit Includes
- Electrical and mechanical inspection
- Infrared thermography (thermal imaging)
- Written condition report
- Deferred items ranked by priority
- Emergency response priority between visits
Cities served: Los Angeles, Vernon, City of Industry, Ontario, Chino, Riverside, Long Beach, and all SoCal cold storage markets.
FAQ
Frequently Asked Questions
Do you work on ammonia refrigeration electrical systems?
Yes. We install and maintain electrical systems for ammonia refrigeration — compressor motors, VFDs, classified area electrical (Class I Division 1 for NH3 machinery rooms), refrigeration panels, and controls. We don’t handle the refrigerant itself, but we cover all the electrical and controls.
Do you provide 24/7 emergency electrical response for cold storage facilities?
Yes. Cold storage electrical failures risk product loss within hours. We provide 24/7 emergency electrical response for cold storage and refrigerated warehouse facilities. PM contract clients are prioritized for emergency response.
Can you do preventive maintenance on refrigeration compressor motors and drives?
Yes. We provide scheduled PM programs for refrigeration compressor motors (megger testing, connection inspection, thermal imaging) and VFDs (cooling system cleaning, capacitor inspection, parameter backup) for cold storage facilities.
Do you serve cold storage facilities in the Inland Empire?
Yes. In addition to the LA Basin, we serve cold storage and refrigerated warehouse facilities in the Inland Empire — Ontario, Chino, Riverside, Rancho Cucamonga. Our Santa Fe Springs shop provides reasonable response times to all three SoCal markets.
What classified area certifications do your electricians hold?
Our electricians are trained and certified for Class I Division 1 and Division 2 electrical work (vapor/gas classified areas, including ammonia). We install explosion-proof motors, classified area panels, conduit systems, and sealing fittings in compliance with NEC Article 501.
