Julie, the account manager has always helped us navigate policies and plans. Roger and his apprentice Mike were prompt for an 8AM appointment to service the oil-fired water heater and furnace. He was very knowledgeable and took the time to explain what they were testing and answer all of my questions. He was great at contextualizing his answers to help me plan for future costs (ie. oil tank, furnace replacement) down the road.
