The AC repairman came out to diagnose my problem. He said that is was low on coolant and added some for free (besides the diagnostic fee). He did say that there was high head pressure at the compressor but he wasn't detecting any odd amp readings (he said that usually go hand-in-hand).
Long story short, he said that I am living on borrowed time with my existing 1974 air conditioner. But he also said that there is no sense in replacing it until it finally dies.
The old Rheem is older than I am and is still blowing cold air. I hope the new ones are built to last that long!
I'm impressed, too. But you should start saving for your new unit now. You don't want to be caught buying it on credit when this one dies, and a new unit will be so much more efficient that it will pay for itself in maybe two years max.

Reason: OK, maybe not in two years. But pretty close. That thing's less efficient than a $99 room A/C!
