The most typical type of heating repair includes problems with the furnace's ignition system. Ignition problems can be caused by a malfunctioning igniter, thermocouple or pilot light. These components are required for igniting the fuel and initiating the heating process. Ignition problems can cause heating inefficiency, intermittent heating, or complete system failure. Prompt identification and repair of ignition issues is critical to ensuring the heating system's sustained operation and efficiency.
