Preventative Maintenance Services

M&I Electric’s preventative maintenance programs provide our customers with the peace of mind that their power system is functioning, properly, safely, and reliably. Our structured programs are custom designed to work with any type or size of system.

M&I Electric designs programs that work with our customer’s budgetary and operational needs. Our programs will ensure that any applicable regulatory and  reliability compliance requirements are met.

A properly maintained electrical system will function correctly and its protective features will minimize equipment damage when called upon to perform. Fewer equipment failures will keep operational costs to a minimum and can extend the life of the system as a whole.
