Gaston Blog Series / Electrical Systems Preventative Checklist

Greetings from the Gaston Electrical Service Division. 2018 is off to a busy start and many companies have already begun their planned projects and improvement programs – including preventative maintenance for building systems. While we stand ready to provide all electrical and technology infrastructure solutions (along with 24-hour emergency service), we prefer to work with our customers in identifying potential issues before an emergency arises.

Preventative Maintenance of critical building equipment can help identify and rectify issues before they escalate into major problems for property management and tenants. These actions will ensure that electrical systems are performing at optimal levels – significantly reducing costly downtime. To help with your proactive planning, we have compiled a helpful checklist of considerations for improved electrical building maintenance.
