Old Lyme, CT - I conducted a comprehensive annual service on a 22KW Generac guardian standby generator. This involved a thorough inspection of all components, including the engine, fuel system, and electrical connections. I cleaned and replaced air and fuel filters, checked and adjusted the oil level, and ensured all moving parts were lubricated. The battery was tested and, if necessary, replaced to ensure optimal performance. I also performed a full system diagnostic to identify any potential issues. Additionally, I completed a firmware update to ensure the generator operates with the latest software enhancements, improving efficiency and reliability. The generator was then tested to confirm it functions correctly and is ready for use in emergency situations.

Old Lyme, CT - A 24kW Generac standby generator was diagnosed with error code 2098, indicating an issue with the communication between the control board and the engine control module.

Review
Residential Generac Generator was inherited with the purchase of my house but pulled offline due to significant renovations. It took 2 years but finally found a business nearby, Generators on Demand, who are specialists (and well trained) in Generacs. I originally just scheduled a service call to get the unit up and running but immediately signed up for annual maintenance with them. Ron was so helpful, explained everything that they were doing and why. He also gave me some very helpful recommendations to keep the unit in perfect condition. Extremely happy I waited to find the best group for service.
