I think you may be confused. In most places it is illegal for a scrap dealer
to buy a used evaporator coil - because the thieves have been chopping them
loose to sell for scrap - but a homeowner can still buy a new one.

That does make more sense.

In any case find the leak if possible first. If they can't find it,
charge the system and see how long it lasts. Charging once a year may
fit better with your situation if you need to get by for a few more
years. It is normally a small amount of loss to cause the evap temps
to drop below freezing, sometimes just a few ounces. Beyond that the
system stops cooling completely.
