Hey I'm still fairly new to the game so please pardon my ignorance, but I was wondering the other day, what is the actual detriment to a HCFC system (eg, R22) if a HFC refrigerant (eg, R404a) is used. I've heard all through my training that the two do not mix but no-one ever actually gave me a reason what happens and what the effect on the system is. If some one could give me an answer to this annoying burning question that would be great!
