Nice response, thanks. I definitely say at that age it’s not ready yet. But I do understand your need for cooling over there is very important. But do a good cleaning with a hose like I did on the outside unit. Then use a hand held sprayer for the indoor coil. Clean you air filter monthly. Plus try to run water through the drain of the indoor coil. But that should happen anyway if you use enough water for the coil. Use some viper foaming coil cleaner spray on coils prior to spraying water on them. Wait a couple minutes for it to soak and then rinse them well. God speed!
