Sunday night our water heater decided to stop working, on our house that is only 3 years old (including new utilities). Being out of builder warranty, we had to call someone to come out and check it out. We called Advantage in the morning, lady on the phone was very friendly and helpful. They were able to get someone in the morning, despite an initial ETA of 2PM-4PM.
