Rob D. was very professional, genuine, and educational - he was able to explain clearly what he was working on, what issues that may arise in the future, etc. He replaced a nozzle that was too big for our heater, explaining how the size was allowing too much oil in and burning unnecessary amounts of oil for our heater to use.
He worked efficiently, as well as updating me along the way as to what he was working on next, and an estimated time on completing the whole job.
I would recommend Rob D. to anyone who needs maintenance on their oil heater.
