Derek Cole explains why drop-in refrigerants don't work in R22 systems. Substitutes have different chemical makeups and won't perform the same, potentially causing extra problems and higher costs down the line. He uses a ketchup and blood analogy to show why they're incompatible.
Whoever is dropping in this refrigerant is never going to get it correct 100% of the time because it's not the same chemical makeup. The manufacturer made that unit to work on R22. It didn't make it to work on the drop in refrigerant for R22. It didn't make it to work on R410, a refrigerant. Okay. You can't put a foreign refrigerant into that system and expect it to act the same. It's kind of, you know, if we talk about your body and the blood a lot, if you put in ketchup just because it's the same color as your blood, your system will not operate the same. Okay? So it's kind of, it's kind of ridiculous. But think about drop in refrigerants. Yes, they're drop ins for R22. But never think that is going to be the solution to your problem because drop ins could cause more problems, could be more expensive over time because you're having to go back and share that over and over again.
