Ben solved some very thorny problems with my boiler. I have a 325 MBH Burnham 2009 steam boiler in…read moremy brownstone that was failing to start up especially after it had been down for a while. I mistakenly thought it was a worn out thermocouple and tried to replace it since I saw it done last time the problem arose. Unfortunately I was doped up on Benedryl to treat a bad head cold and caused a major short circuit of the controls while attempting the work. Having no idea of the extent of the damage and how to repair it and having bad luck with my previous contractor, I submitted inquiries to several contractor referral sites. Ben is on Yelp & Thumbtack and responded to me quickly. It was the weekend and the house was getting cold so I thought I should try him. He was very methodical and thorough in his work. It took several days while he was testing and replacing wires and testing the controls. While prepared to replace all the controls, he found that he only had to replace the 12 volt transformer and low water cutoff. He drained and cleaned out the boiler prior to installing the new cutoff. Apparently the boiler had been failing to start due to sediment from the dirty water on the water level probe of the low water cut off. He advised me how to periodically clean out the boiler to prevent the problem from recurring. Contrary advice I got from my prior company led to this problem. Unlike me he knew exactly what he was doing. His solutions followed an expert step by step diagnosis which lead to finding what needed to be replaced and not replacing more than was necessary and then checking all controls to make sure the boiler is operating properly and safely. He was also a pleasure to work with: friendly and respectful. I learned three major lessons from this experience: 1. Don't assume that the solution to a problem will be the same solution next time the same problem arises. The main original problem was not a worn out thermocouple but rather dirty water. Correlation is not causation. 2. A little bit of knowledge can be a dangerous thing and never try to do possibly hazardous work when you are not clear headed no matter how smart or brave you think you are, and 3. Always call Ben if you have another problem with the boiler even if it is just replacing a thermocouple! Thanks again Ben
