Which maintenance task can help prevent overheating in heating systems?

• A. Replacing old insulation
• B. Regularly checking thermostat settings
• C. Cleaning the air filters
• D. Draining the system regularly

Answer: (C)

Cleaning the air filters is crucial in preventing overheating in heating systems because clogged or dirty filters restrict airflow. When airflow is limited, the heating system has to work harder to maintain the desired temperature, which can lead to overheating. This not only decreases efficiency but also poses a risk of damage to the system and can reduce indoor air quality. By regularly cleaning or replacing air filters, the heating system can operate efficiently, ensuring proper airflow and reducing the likelihood of overheating. The other options, while relevant to the overall maintenance of heating systems, do not directly address the airflow issue that contributes to overheating as effectively as cleaning the air filters does. For example, replacing insulation is important for improving energy efficiency but does not directly manage airflow. Checking thermostat settings ensures proper temperature control but does not affect how well air circulates. Draining the system can help in certain contexts but isn’t a regular maintenance task aimed specifically at preventing overheating. Thus, maintaining clean air filters is the most direct action to prevent overheating.
