My Bryant system was installed 6 years ago by another dealer. During a routine maintenance check, the company's tech told me my heat exchanger was rusted and carbon monoxide levels were high. He said they had dropped Bryant because they wouldn't stand behind their products, and tried to sell me a Carrier system (red flag: Bryant and Carrier are made by the same company). I called John Waters for a second opinion. Turned out the heat exchanger was fine (some dirt but no rust) and CO levels read zero. Honesty is critical; John Waters will be doing my maintenance in the future.
