Air Conditioners don't 'Use' freon per se. A common fallacy is the thinking that if "It's not getting cold, then it needs freon." If your unit lost freon, it has a leak and adding freon will only be a very short term fix.

If you're certain that you need freon, you'll have to take the unit to a certified HVAC technician. EPA regulations make it nearly impossible for the average handyman to service A/C units, since the freon must be handled in a very specific way with equipment not generally available to the average owner, was well as R-12 freon gas which can be bought only by licensed HVAC technicians.

However, there are many other problems that are far more likely to be the cause of no cooling than loss of freon. It could be something as simple as dirty condenser coils (you'd be surprised how common it is that a simple cleaning of these coils will 'fix' a non-working window A/C), to a defective thermostat switch, to other defective switches/controls.

Unless it's a very obvious leak, I always suspect a loss of freon LAST on my list of possible cause of non-cooling in these units.

There should be a metal tag with the identification number and all details stamped and riveted to the back, sides or even underside. But usually on the back of the unit. But whatever is written on it is meaningless if your unit is not cooling to your satisfaction, plus it may have lost the refrigerant over the years and become less efficient. So depending on the room size you can buy a new unit. Or depending on which county you are in you may be able to have it recharged with the refrigerant.

it depends the temperature,never is the same time,depends how hot or cold is the weather.depends the thermostat regulation by the user. colder sets get more time running at hot weather

Hello, Usually on a window AC there is no drain plug. It relies on the tilt of the of the AC. The AC should be installed with a slight rear tilt so the water flows to the rear to where there should be two factory drain holes. Besure to get proper drainage otherwise the fan will pick up water and blow it into you house and cause humidity. I have also drill a hole on the lowest location on the bottom of the chassis to help drain it seven better. Your AC depending on where you live and how humid it is will collect more water on a humid day than a dry day and also the effenciancy will be worse on a humid day.
