Our factory trained Field Service Engineers are rigorously trained and tested on how to efficiently service our products, as well as on safety practices and electrical codes, offering our customers the highest level of service available in the industry today. Cleaning your system of dust and grime accumulated during normal operation will extend the life of the hardware. In order to ensure that your system is installed in a suitable environment for optimal functionality, we will inspect the site for conditions that might damage your system, such as excessive heat or humidity. During each Preventive Maintenance visit, our Certified Field Service Engineers will run tests to verify your system is functioning correctly in all operational modes, stopping problems before they start. Part of maintaining your system is ensuring the unit is operating with the most recent firmware version. Firmware upgrades are provided at no extra charge. All Preventive Maintenance contracts include free firmware upgrades. If you are like most businesses, you want your systems up and running during your busiest hours. In order to accommodate your busy schedule, APC offers an option to schedule services off hours. We will work with you to find a time when servicing your system is least likely to impact your productivity, saving your business time and money.
