I use Hickey Electric to do annual maintenance on my whole house generator. I have over $10,000 invested and want to make sure it performs as required and will last me a long time. John, the service technician found that my main electronic control board was malfunctioning and determined it was covered under warranty by the manufacturer. It would have cost me about $2,000.00! Instead it only cost me $340.00. That was the cost of labor and I needed a new battery for the generator.....As long as I own this generator, Hickey Electric will be performing my maintenance and repairs!!
