Excessive dust accumulation in a gas heating system can lead to potential system failures. This is primarily because dust can obstruct airflow, which is crucial for optimal combustion and heat distribution. When airflow is restricted due to built-up dust, components of the system may overheat or function improperly, leading to malfunctions. Additionally, the accumulation of dust can hinder the operation of essential parts, such as filters, burners, and heat exchangers, resulting in a failure to operate efficiently. Ultimately, this can cause the system to break down or necessitate costly repairs, making it essential to maintain the system free of excessive dust for reliable operation.

The other potential choices do not accurately reflect the implications of dust accumulation. For instance, higher humidity levels are not directly linked to dust buildup in gas heating systems, and increased efficiency contradicts the idea that dust would hinder performance. Furthermore, while a decrease in operational lifespan can occur as a consequent issue of system failures, the most direct and immediate concern related to dust accumulation is related to the potential for actual system failures.
