SERVICE AND MAINTENANCE
At Grunau Company, we offer service capabilities for the repair, retrofit
and maintenance of many systems including mechanical, automatic temperature
controls, plumbing, electrical, underground utility, fire and life
safety, and indoor air quality.
Our customers regularly work with the same technician, allowing them
to develop friendly relationships based on trust that result in greater
peace of mind. We use communication and data storage technology, like
FieldCentrix, a hand-held wireless system, that allows technicians
to access service and maintenance information on every piece of your
equipment. They stay up-to-date on its status so you don't have
to. In addition, every Grunau service truck is equipped with a Global
Positioning System (GPS), allowing the rapid dispatch of the closest
qualified technician.
