When the heating system went out last winter, I had to call a repair service. They diagnosed the issue as a faulty ignition sensor, which was causing the furnace to shut off randomly. The technician replaced it and cleaned the burners, and the heat has been steady ever since. It cost a few hundred, but it was worth it to avoid freezing pipes.
