Called Day and Night Plumbing to do a service for my gas furnace and the service person Christopher Bryant found an unsafe condition in my furnace (CO2 levels were high) and looked into it further and found that it was improperly installed and the secondary heat exchange had rusted out. He ordered a new one and installed it in now time. He was a true professional and probably saved our lives. I would hate to think what would have happened if I had turned the furnace on in the fall without it being fixed.
