When your building is completed, Mueller & Wilson doesn’t walk away from the job. In addition to providing warranty service for the systems we install, we also offer a variety of service and maintenance contracts to keep them running at peak efficiency.


No matter how complex or specialized your system requirements are, Mueller & Wilson has the capabilities to complete the project. The installation shown at the left is one such example.

Mueller & Wilson installed the Liebert units and ductwork system at the San Antonio Express-News, where large, computerized presses must operate in a controlled environment. The Liebert units maintain constant temperature and humidity, and also filter out paper dust, ink fumes, and ink overspray from the interior environment.
