Systems Engineering prides itself in providing the best customer service in the industry.  We stand by all of our products, even the SEM 500, our first mechanical control system, introduced in 1970.

Our service department can be contacted Monday - Friday, 0900 - 1800 PST at 206.633.4972, or at


Systems Engineering recognizes that each customer is as different as their installation needs.  That's why we allows the customer to perform as much or as little of an installation as they want, always making sure that the customer has access to the necessary resources.  In addition we can integrate a new installation with components from previous systems, which saves you time and money.


Systems Engineering understands that part failures can directly impact your bottom line.  In turn, we understand the importance of providing service parts in a timely fashion.  To that end we maintain an extensive stock of parts for all SEI products, including critical parts that have low turn-over.  We  maintain close relationships with our partners to ensure that we can provide  replacement parts as quickly as possible.  In the event that a part is not available we can sometimes custom manufacture substitute parts to get you running.


Systems Engineering offers a full range of maintenance services, with factory trained technicians.  Our in-house service departments is available for repairs locally or internationally, and offers preventive maintenance consulting.
