Maintenance testing is a test that is performed to either identify equipment problems, diagnose equipment problems, or confirm that repair measures have been effective. It can be performed at either the system level (e.g., the HVAC system), the equipment level (e.g., the blower in an HVAC line), or the component level (e.g., a control chip in the control box for the blower in the HVAC line).
In minimal maintenance concepts, there may be minimal or no I-level maintenance, a system known as two-level maintenance (O-level & D-level). A system deploying a typical I-level repair capability would be known as a three-level maintenance system (O-, I-, and D-level).

In heating, ventilation, and air conditioning (HVAC), testing, adjusting and balancing (TAB) are the three major steps used to achieve proper operation of heating, ventilation, and air conditioning systems. TAB usually refers to commercial building construction and the specialized contractors who employ personnel that perform this service.
Maintenance, and hence maintenance engineering, is increasing in importance due to rising amounts of equipment, systems, machineries and infrastructure. Since the Industrial Revolution , devices, equipment, machinery and structures have grown increasingly complex, requiring a host of personnel, vocations and related systems needed to maintain ...
The roots of the industrial engineering profession date back to the Industrial Revolution.The technologies that helped mechanize traditional manual operations in the textile industry including the Flying shuttle, the Spinning jenny, and perhaps most importantly the Steam engine generated Economies of scale that made Mass production in centralized locations attractive for the first time.
The CxP typically does not actually perform the hands-on testing, as these are actually performed by the manufacturer, vendor, or trade contractors, and directed and observed by the CxP utilizing testing procedures and expected performance outcome previously identified by the CxP during the commissioning document development process.
Facilities engineering evolved from plant engineering in the early 1990s as U.S. workplaces became more specialized. Practitioners preferred this term because it more accurately reflected the multidisciplinary demands for specialized conditions in a wider variety of indoor environments, not merely manufacturing plants.
