Frequently asked questions about O&M

How often should my system be serviced?
At least once a year – depending on the size, location and technology of the system.
Can I also have older systems serviced?
Yes - we also take on existing systems and optimise them as needed.
How much does O&M cost?
The costs depend on the scope and size of the system. We would be happy to provide you with a customised quote.
How can I tell if my system is working properly?
Our monitoring system detects deviations at an early stage – and our team initiates prompt measures as part of 24/7 monitoring.
