when the air does not comes out cold in your ac will be a good time
Unfortunately, I do not know of anyone who does this. They are, I'm afraid, a throw away item. It must be replaced with a new one.
No, not even a little. it needs to be reclaimed with a specialized piece of equipment. odds are that no one will know but if you are caught there are big fines involved
If your air conditioner blows air but it's not cold air then you probably need freon in your air conditioner
Well, I know when a tire on my car needs to be replaced when there is no tread left on it. What are YOU referring to
if you had the gauges,the know how,and the epa card to purchase freon.Then sure.
To know when an air conditioning unit (non-window unit) needs to be charged (needs freon), it will not cool properly or you can test it with the appropriate gauges (see related link below).
Possible freon leak in the coil of the unit and the fan is circulating it into the air. As we know freon is toxic to the environment imagine what it can do to a human body.
refrigerant 135a is the the standard freon used and sold at most auto parts/retail stores. You can even do it yourself.
How do you know if it needs to be replaced
it goes out and your heat will be gon
Requires instruments and knowledge of the refrigeration cycle. Casual observation of a system, won't allow you to properly determine if it's overcharged.
There is a misconception that all refrigerants are freon. The EPA has band use of freon R12 in the USA. It is no longer produced stateside. The only refrigerant that is acceptable for automotive use is R134A. If you are to attempt to service your air conditioner you will need to know the exact amount needed. It is very critical on cars.
