old refrigerant is a gas and needs to be pumped out or removed via vacuum with the proper machine which deposits it into the same type of tank that new refrigerant is contained in because of pressure.
evacuating refrigerant into the air is dangerous and if inhaled is poisonous to people. not to mention illegal if in California. You could try one of those conversion kits from r12 to r134 hooking up the hoses may allow refrigerant to flow into an empty refrigerant btl.
Is it a new or an old window unit? Assuming your looking to refill it I will assume it is an old window unit which most likely uses R-22 refrigerant. R-22 is an ozone depleting refrigerant that is being phased out but should be available until 2010. There should be a label on the window unit stating which refrigerant is used.
Look on the outdoor compressor, there should be a sticker that tells you what kind of refrigerant it uses. If it says r22, it is the old type.
You really need to flush out the old stuff. But any garage can do it if they will.
Well, It depands on what kind of guy it is. If it is a Jerk and Jokey guy, then NO! If it is a nerd kind of guy, sure! Knock yourself out!
Probably not completely a do-it-yourself job, unless you want to become an ozone hole creator. Basic steps are as follows. This is a bit of a complex job to answer in sort of forum. For specifics on the nuts and bolts of removing the actual compressor, check your Chilton or Haynes manual or hopefully someone else will chime in. Connect the car to a refrigerant recovery machine, pump the refrigerant into the recovery tank, remove the belt, remove and replace the compressor, reconnect recovery machine, pump out air and moisture, and recharge the refrigerant and oil. When the system is opened, it's recommended to replace the filter drier (moisture will kill the a/c system). A few notes: A refrigeration tech will collect the old refrigerant rather than releasing it to the atmosphere. It is a CFC, which neutralizes ozone in the atmosphere - hello global warming. Venting refrigerant is a federal crime. Refrigerant is very costly nowadays. Even replacing it yourself you will spend about $60 or more on the refrigerant alone, if you can find it at all. If you do it yourself, it's best to have a pro handle the refrigerant removal and recharge. If you don't, the open lines will likely collect moisture, which can lead to system failure of you new compressor or evaporator.
No. You absolutely cannot mix any refrigerants. You should completely recover all the old refrigerant and charge the system, with the new refrigerant, using the superheat method.
It is a refrigerant. R134a is the common type. The old generic name is Freon.
I like to collect stikers, but also i collect old Coins and 2 Dollar bills.
A hole.
THere are people like me who collect old tubas. What are the markings on the instrument?
The term "lid" has its origins in Old English, where it referred to a cover or top of a container. Over time, it has evolved to refer more broadly to any kind of covering or cap.
