Commercial Lighting & Electrical

MacDonald-Miller provides proactive electrical maintenance that meets current NFPA 70E requirements, helping you reduce risk, improve documentation, and stay prepared for insurance, fire marshal, or L&I reviews. From arc-flash studies to infrared scanning, our code-compliant electrical services deliver a safety-first approach and audit-ready documentation, including clear records and recommended corrective actions.

Our integrated team coordinates electrical work with HVAC, controls, and service to reduce handoffs, speed up fixes, and provide a single accountable partner when issues span multiple systems.

Electrical System Maintenance

Through proactive inspections, thorough testing, detailed documentation, and safety-focused evaluations, we provide full operational maintenance of your electrical distribution systems in compliance with NFPA 70E standards.

Panel Maintenance

Our proactive panel care helps prevent overheating, arcing, and costly failures. Our maintenance plan is designed to keep your electrical systems at their peak while keeping them safe, reliable, and compliant.

Infrared Electrical Testing

Advanced infrared thermography detects hidden faults such as overheating components, loose or faulty connections, and hidden electrical issues before they cause failures or safety issues. This non-invasive testing method helps reduce downtime and improve the reliability of your building.
