Whats the right settings for the window air conditioner.

What you describe is what window air conditioners do.

How do I tell the age of a Fedders furnace or air conditioner from the serial number?
Although the Fedders brand is used for window units nowadays, this encoding only applies to when they manufactured unitary (split) systems years ago. The second letter of the serial number indicates the year of manufacture (from 1966 to 1977):
A = 1966 B = 1967 C = 1968
D = 1969 E = 1970 F = 1971
G = 1972 H = 1973 I = (not used)
J = 1974 K = 1975 L = 1976 M = 1977
An ancient Fedders unit we recently inspected had the serial number AH11877, indicating that it was manufactured in 1973. The home was built in 1973, which provided a secondary verification of the manufacture date indicated by the serial number

It prevents the unit from short cycling and killing the compressor. The air vent brings in outside air to "refresh" the indoor air.

Hi There,
It needs to be re-charged with freon.

Dirty coils, restricted air flow, broken fan blades, faulty thermostat, Gas leaks are a few possible causes for this to happen.
