find out anything new on yur ac prob reds
alot of good info did yuh try any yet
simple math first
clear yur debri if any from the cooler fins
you can usually stick a small pin in the drain hole of the condensor , if its not draining , it will be harder to cool, mine drains like the water faucet was left on.
then check yur damper doors like jones said could be hangin up
best of luck
