What is the first step in performing the annual tune-up for oil heating systems?

The first step in performing the annual tune-up for oil heating systems involves talking to the customer. Engaging with the customer provides valuable insights into the system's performance and any issues they may have encountered since the last service. This interaction helps gather information regarding unusual noises, fluctuations in heat output, or any other concerns that might affect the tune-up process. Understanding the customer's perspective allows the technician to prioritize specific areas to address during the service, ensuring a more efficient and effective tune-up.

While inspecting the burner, checking the oil supply, and testing safety devices are all crucial components of the tune-up process, these actions can be more effectively performed after initial communication with the customer has taken place.
