Yes, it is used in home central A/C units and heat pumps as well as commercial chillers and other large refrigerated units. Products using R22 will cease production by 2010, and the production of R22 will cease by 2020. It, like R12 is being replaced by R134a.

The refrigerant level can get to a point so low that the compressor will not run. If you don't hear the "clicking" of the compressor relay now and then, it means the level is too low to allow the compressor to kick in.

The refrigerant will only flow if the compressor is running. If this is the case, a pro will have to do it for you.
