Preventive Maintenance: common questions
Why pay for preventive maintenance?
Most electrical failures give warning signs first: loose connections, hot spots, and worn parts. Catching them on a scheduled visit costs far less than an emergency call, lost production, or a shutdown.
What is an infrared thermal scan?
A thermal camera shows heat you cannot see with your eyes. We scan panels, switchgear, and connections while they are running under load to find hot spots before they fail, with no shutdown needed for the scan.
How often should our building be serviced?
It depends on the building and the equipment. Many facilities run lighting rounds monthly or quarterly, and electrical inspections and thermal scans once a year. We set a schedule that fits your building, your insurance requirements, and your budget.
Will maintenance visits disrupt our operations?
Most inspection work, thermal scans included, happens with your equipment running. Anything that needs a shutdown gets scheduled for nights or weekends so your building stays open.
Can one program cover all of our locations?
Yes. Multisite and multi tenant portfolios get one program, one point of contact, and the same standards at every location in our service area.
Do you handle arc flash labels and electrical safety audits?
Yes. We update arc flash labels and run electrical safety audits so your equipment is marked correctly and your team knows what they are working around.
