Manual For Replacing R22 With New drop In replacements
Can anyone reccomend a manual that gives full details on using R22 drop in replacement Refrigerants? Any info will be greatly appreciated. I have retired from HVAC work but hearing about the new stuff whets my interest and I still do an ocassional service call to help out at my former shop.
have heard lots of discussion and talk about the subject but can find little info. Iggie
