Yestramski Electrical Services Inc. & Emergency Power Systems

About Us

Yestramski Electrical Services was started in 1989 by Tom Yestramski.  The business began as an electrical contracting business, and developed a strong clientele across the Northeast.  Our commitment to providing quality services and holding our customer's needs first has built the foundation on which YES has grown.  In 1998, we became a certified Kohler Platinum Dealer and began providing Emergency Power Systems to our residential and commercial customers.
Our team of generator technicians work on every make and model of generators and are certified with Kohler, Generac, Cummins and Briggs & Stratton systems. Generator service and repair are their primary focus.  Because of this, they are experts in their field and, as such, guarantee complete customer satisfaction.


We have been providing superior electrical work since the origin of the business in 1989.  Our team of licensed electricians are committed to ensuring that the work they provide is compliant with the National Electrical code.  This ensures the safety and peace of mind for all of our customers.  From a simple switch install to a large home remodel, every job is given the same expert attention to detail and quality customer service.

Our Mission:

To provide exemplary service and peace of mind to our customers.


Project: Install a Generator
I can't say enough about this company!! We had a horrible ice storm here, and we had them come out. Tom spent 3 hours with us at first and explained absolutely everything, answered all of our questions. The techs were fantastic!! The would come and update us about the next phase of the job, and even warned us of noises with such care. They are wonderful at following up to take care of us as well. Marvelous, charming people who can be trusted.
