17FEB2025 Jason Brown Arrived for a replacement bid. Spoke with Yilmaz about his systems performance. He showed me the furnace and explained that there is a crack in the heat exchanger. Found the system to be a downflow, homeowner mentioned that they were getting some sand from the registers years ago but not now. I asked to inspect the ac and ductwork, but the attic access is blocked and homeowner showed me a picture of the model and serial of the AC. Inspected furnace and evap and sized equipment based on what was available. Discussed financing and warranties. I explained we can change the system out but without addressing the ductwork it can cause major problems. Attached are discussed quotes. It was good meeting you thanks for giving us a call!
