If it is not freezing up freon is ok. Make sure compressor is running.If humidity in house is high It will not feel as cold as it should until air drys out some. Do not try to run just after house heats up as it may never catch up. LEAVE ON a set stat to cycle. Window units have no customer acess fittings and would need to be installed. Then you need gauges to read pressures. this is not auto refrigerant. 90% of the time the outside coil is dirty and needs washed out. fan blows back through coil so build up is on fan side you can't see. You may be able wash with hose from side you can see with a 30 degree down angle going from top to bottom side to side. careful to not bend fins Also do not spray water into fan motor. Also some times coil is too dirty to clean without taking apart.

R410 units are cheaper now but not as effecient as R22, also R22 is much more expensive and most likely you would have to use R22 a to recharge unit if it as allowed where you live .
