What are the consequences of neglecting furnace maintenance?

Neglecting furnace maintenance can lead to reduced heating performance, increased energy bills, and even safety hazards. A dirty or clogged furnace can cause it to work harder, increasing energy consumption and reducing its lifespan. Moreover, a malfunctioning furnace can produce carbon monoxide (CO), a colorless, odorless gas that can be deadly in high concentrations. Regular maintenance helps prevent these issues and ensures your furnace operates efficiently and safely.
