ARS/Universal scam artists (Stefon to be specifici) and Moncrief rep said I had a R22 system and needed to be replaced to upcoming R410. Each quoted a new system at either $7000 or $9000. Maxwell's Jeremy and Thomas evaluated the problem. Solution: I need 3 pounds of refrigerant, total cost with service call: $320! I let you draw your own conclusion. Call me if you have questions: 404-441-2858. You too, Stefon.
