Generator Installation, Repair & Maintenance

Shepp Electric Co., Inc.'s technicians have been factory trained and certified for both residential and commercial generators for over 30 years. Even during the warranty period it is highly recommended by the factory that the generator units be inspected and serviced on at least a yearly basis to keep them in top running condition. Shepp Electric Co., Inc. offers that service under contract and has factory trained and certified technicians performing this important service. Unlike some companies with little experience who may claim to know what they're doing, our technicians are highly experienced since they have years of experience on ALL sizes of units and engine types. Behind the scenes our incredible office staff will keep a complete service history record on every unit installed from day one. This helps each technician to offer the highest level of service and maintenance for each customer, over 2,000 every year!

Below is a listing of checks and services that are performed on the yearly maintenance inspection and can vary according to size and model of unit.
