I called and made an appointment for one day, the service provider call me back to say that he couldn't fill my appointment that day. He said I can call and rescheduled with someone else if I wanted to. So we rescheduled for another day that he can come out on an he did. He was punctual and he asked me about what was the problem and I inform him that I wanted an estimate on my hot water heater. He consulted with me and gave me an estimate of how much the work would cost.
