I just wanted to let you know that the technician from Sandy Hamilton Plumbing and Heating was over today to help me with the issues I was having.  He was wonderful. He explained everything thoroughly to me so I would have a good understanding.  I feel much more comfortable knowing how things are working.  He worked extra hard trying to find the noise in the furnace.  Because of the ambient noise around us and the outside noises, it was difficult to say whether it was still present.  He tried several things he felt may be causing the unwanted noise.  I told him that if he didn’t see/hear anything out of the ordinary and it was throwing heat, then I wasn’t too concerned.  He did a great job!
