I am a highly skilled and experienced home service professional. I recently completed a job where I went to inspect a furnace and found severe amounts of rust in the heat exchanger. The heat exchanger was red-tagged due to safety issues, and I shut off the breaker to prevent it from starting. The client was advised to look into a dehumidifier to help extend the lifetime of the heat exchanger. I also provided estimates for heat exchanger replacement with a dehumidifier and estimates for longer-lasting solutions. The client was grateful for my advice and appreciated the detailed information I provided.
