What type of maintenance can help prevent excess energy use in heating systems?

Regular cleaning and filter changes play a crucial role in maintaining heating systems and preventing excess energy use. When filters are clogged or dirty, they restrict airflow, forcing the heating system to work harder to circulate air throughout the space. This increased workload not only leads to higher energy consumption but can also shorten the lifespan of the heating system due to additional strain on the components.

Moreover, keeping the heating system clean ensures optimal performance and efficiency. Regular maintenance tasks, such as cleaning components and replacing filters, allow the system to operate at its designed capacity, effectively distributing heat without unnecessary energy expenditure. This proactive approach helps in maintaining consistent indoor comfort while minimizing energy bills and system wear.

On the other hand, increasing appliance size would not directly contribute to energy efficiency and could lead to higher energy costs if the system becomes oversized for the space. Avoiding inspections fails to address potential problems before they escalate, leading to inefficient operation. Using unsealed ducts would lead to significant heat loss, further contributing to excess energy use rather than mitigating it. Therefore, regular cleaning and filter changes represent the most effective maintenance strategy for preventing excess energy use in heating systems.
