    "I contacted Mark shortly after my heating system failed to produce hot water. Mark responded in very short order and arranged to visit during his evening. Mark is extremely knowledgeable, professional, and importantly, delightful to have around. Mark not only took the time to solve the issue, but explained to me the inner workings of the problem, and my heating system at large. If you are within Mark's remit, do not hesitate to contact him. I have worked with numerous gas technicians over the years, and it is challenging to find another as professional as Mark."
