I had no idea that the internals of my heating and cooling system was this far gone. The heat exchanger was leaking just a tiny bit, but that’s deadly because of the carbon monoxide. The coils were rusted and seemed to have a small leak too. I have to give the old system kudos though as it made it 25 years! The crew was impressed that it made it this far. Mostly sunny and 99F is forecast for today, perfect!
