I performed a thorough plumbing maintenance check, ensuring no leaks, and flushed the hot water tank to ensure optimal performance. I also discussed the client's previous experiences with Dormar and addressed their concerns about the air conditioner and electric bills. I discovered a failing heat exchanger in the furnace, requiring immediate attention. I provided options to the client and advised them to do more research on different furnace styles before making a decision. I will reach out to the client this week or next week to discuss the next steps.
