Does furnace work without power
In short, a furnace requires electricity to operate. Without power, it won’t be able to function. The furnace uses electricity to power the blower motor, which circulates the warm air throughout your home. The furnace’s ignition system also requires electricity to ignite the fuel and create heat.
However, some furnaces have a backup power source, such as a battery or generator, that can keep the furnace running in case of a power outage. It’s important to note that these backup power sources are typically only designed to keep the furnace running for a short period.
In a power outage, it’s always best to have a backup plan for staying warm, such as a generator or alternative heating source. If you’re unsure about your furnace’s backup power capabilities, it’s best to consult with a professional HVAC technician.
