I replaced an American Standard condenser and a Goodman evaporator coil this past spring, and I got 7 years out of it. It cost me $7000 or $1000 a year. The condenser leaked, and the coil also leaked. Thought I was OK until late August and the same thing happened to the other unit. In this case, it was just the defective coil, but as the tech said, replace the condenser since it is the same age as the last one, and if it goes bad next year, it will be much more expensive. Seems that the refrigerant that the units use is being discontinued at the end of 2024, and no replacement parts can be sold for the older units. The coils leak because the pan they sit in doesn't fully drain and the condensate attacks the metal. The new units have a new pan, but they haven't fixed the problem. The tech told me that had I had the units cleaned every year, the problem wouldn't have existed. When the new unit gets installed, he is going to put a tee into the drain line so the line can be cleared with a round brush in the future.
The unit at my wife's store was just replaced. It was 41 years old, and the case looked like it had been in a war, but it still was working, but extremely inefficiently.
