Service is an important part of the life cycle of a hot water system. From the very first commissioning we can assist in optimizing the user comfort by programming the installation exactly to the needs. Annually water side maintenance, and if it concerns a gas appliance – gas side – maintenance, directly contributes to the operation and the life of the installation.

Technical support

Of course there is also the service that you would expect from a manufacturer of high quality products. This includes troubleshooting and having technical support available on site.


A.O. Smith believes that good service does not end with the delivery of an installation, but remains available throughout the entire operational life of your water heating system. It starts, for example, with the commissioning of your system. A.O. Smith can play a major role by inspecting the entire installation.


On request, A.O. Smith can also provide both preventative and regular maintenance for your installation. Keeping vital parts in good working order is not only essential for a consistent supply of hot water; it also ensures the appliance’s efficiency.
