A Maintenance Technician oversees all the work involved in the upkeep of property or campus. As a Maintenance Technician, you are a jack-of-all-trades and need to know how to repair almost anything, from fixing broken windows and unclogging toilets to replacing carpeting and painting walls. When you receive the repair request, you complete the project in a timely, cost-effective manner. You also perform routine, preventative maintenance to mechanical systems, including the HVAC and plumbing systems, to increase their efficiency and longevity.
