Monthly or Quarterly Maintenance Inspection
Minimum Four Visits
Commercial generators need a minimum of four maintenance visits per year.
We don’t just “take a look”—we go through a 40-point maintenance checklist.
We Include ATS Inspections
The automated transfer switch is a critical but often overlooked component of your generator system.
According to the National Fire Protection Association’s 110 standards, you need a minimum of four maintenance visits per year to keep your equipment operating properly. All equipment manufacturers agree with this minimum standard.
However, businesses typically request more frequent visits when equipment reliability is critical to health, safety, or profitability. When in-house weekly or monthly maintenance checks cannot be performed and documented regularly, we recommend 6-12 visits per year.
When we aren’t performing annual maintenance on specific systems, these visits will be standard maintenance and inspection (MI) visits. During an MI visit, we will do the following:
- Perform a 40-point maintenance inspection
- Inspect the automatic transfer switch (ATS), if appropriate
- Test the unit
- Provide you with maintenance inspection reports and recommendations
- Clean the unit of dirt and debris
Each time we visit your equipment, we’ll evaluate the need for special services. If any work is required, we will inform you immediately and give you a proposal on how to proceed.
