Operation and Maintenance (O&M) services are the essential tasks performed to keep a facility, equipment, or system functioning efficiently and reliably. These services can encompass a wide range of activities, from routine inspections and preventive maintenance to troubleshooting and repairs.
The primary goal of O&M services is to ensure that assets are operational and available for use when needed. This is achieved by:

Preventing problems through regular maintenance tasks like cleaning, lubrication, and part replacements.
Identifying and addressing potential issues before they can cause significant downtime or equipment failures.
Responding promptly to problems that do occur to minimize downtime and restore functionality as quickly as possible.
