The Service Man talked down about my hot water tank and furnace. I did not like his approach. He was very knowledgeable about his job. I did not like the way he came into my home hitting a light switch, trying to turn on a light, and it wasn’t the right switch, I thought that was very rude. The representative made me feel like my equipment in my home was garbage. I got a second opinion and was told something totally different about my furnace. I feel he should not come into a person's home trying to sell because I feel I paid $90 to be insulted.
