If an oil furnace is not achieving proper airflow, what is a likely outcome?

When an oil furnace does not achieve proper airflow, one of the most significant outcomes is reduced heat output. Airflow is crucial for the combustion process and for transferring heat throughout the home. If the airflow is insufficient, it can lead to incomplete combustion of the fuel, meaning not all the oil is being burned effectively. This results in less heat being produced, as the furnace is not able to generate the necessary temperature to heat the air adequately.

Moreover, the lack of proper airflow can also lead to other issues such as increased carbon buildup, burner malfunction, or overheating components, further diminishing the furnace's efficiency and performance. Therefore, maintaining optimal airflow is essential for ensuring that the furnace operates effectively and delivers the intended level of heat to the living space.
