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

Do you mean dry ship R22 units? Just get the install guide on the condensing unit. They ship with a holding Nitrogen charge. They are only available in 13 SEER

You will need a 13 SEER indoor coil to be sure you have enough coil surface area to avoid problems.
