 drop-in replacements. So if the caller or a text messenger is asking because they feel R22 is too expensive or they can't get their hands on some, we can convert an R22 over to a different compressor, or I'm sorry, a different refrigerant that's more like a drop-in to replace the R22. Unfortunately, we just can't do the compressor arrangement. Everything changes at that point. Your condenser coil is different size.
