The transformer pad mount installed cornering my backyard has been humming since the day we moved in to the house in 2007. After figuring out the source of the noise, I had been fighting with Xcel Energy to get this resolved. They behave like an elephant mammoth which would not even feel touched even when a poor consumer like a moth hits it with full force. After many complaints, I was able to force them to have the transformer replaced, but the noise has not died down and my sleepless nights continue. Wakeup! Xcel.
The complaint has been investigated and resolved to the customer’s satisfaction.
