The first visit from was Florent, who was very knowledgable about radiator boilers (mine is a pressure type with one exhaust in the basement). After checking electrical and gas connections, it was clear the electrical switcher to open gas to the furnace was not responding. Initial idea was to replace the furnace ($$$). I paid nothing at the conclusion of the visit, and was to await a response from Mr. Templin (owner). Mr. Templin then called within 1-2 days later and arranged a personal visit, as he explained steam boilers are often reparable. Having located a replacement electric switch for natural gas boilers, Mr. Templin replaced the switch, and also replace the 30 year-old thermostat for under one thousand dollars. A significant savings over a boiler replacement. They know their trade and you will be delighted.
