I love this board.
You can ask any question about anything on here and someone who is an expert - and probably who works in the field - will have a correct answer.
So here I go:
I live in Atlanta...and it gets freaking hot and humid here (duh) so my air conditioners require that they be in tip-top shape so they can keep up.
My downstairs A/C is struggling a bit, so yesterday I gave both my upstairs and downstairs units the full treatment that I am capable of - I took apart the outside unit and cleaned the coils - they were dirty for sure - I gently vacuumed them clean of fuzz and grass and pollen and leaves and crap that had gotten in there careful so as to not bend the fins, and then I sprayed a can of that coil cleaner that Home Depot sells on them and rinsed them gently with the garden hose...they are now shiny and silver once again.
Then, I put brand new filters on the inside units.
My question is about refrigerant. I know about cars...R12 is the banned stuff that is going to ruin the Ozone layer and kill us all that is super expensive if you can find it , R134 is the new stuff that replaced the R12 that is safe for Earth but doesn't work as well, but you can buy at any auto parts store...but what about R22 that is in my home air conditioners?
Is R22 "controlled" and I need to be licensed to put some in? Can I go buy some gauges and do it myself? There is a temperature / pressure chart on the unit I could use if I can get my hands on the gauges and some of the R22. Or is it also now banned and super expensive, with a modern replacement in newer units?
Hit me with the skinny!
