What is a maintenance contract?

A maintenance contract regulates the regular inspection, care and maintenance of technical systems such as heating systems, heat pumps or ventilation systems. It defines clear agreements between client and service provider — including services, intervals, duration, costs and legal framework conditions.

Regular maintenance increases operational safety, optimizes energy consumption and extends the life of the system. In addition, a maintenance contract helps to maintain warranty claims and comply with legal requirements.
