Has anyone converted a home split HVAC system from r22 to one of the replacements, such as HC22a or M099?

Dennis I think Matt Colie did a roof AC unit once with some success.
A residential unit would be a really bad idea. Someday a professional will work on it and will contaminate some amount of R-22 (could be a lot) when he tries to reclaim what he thinks is R-22 from the HC charged system.
Thanks for the input.
In this case it is a HVAC person giving the option of a new coil and converting to Mo99, a DuPont substitute for r22.
I have just not heard about Mo99 nor much about other substitutes.

Hi Matt
Thank you. The evaporator coil is leaking, 18 years old, so new as an option versus repair.
And of course their other option is a new 410 system, both outside unit/compressor and new evaporator.

If the leak is in a joint or u bend I would just fix it. I believe you can find r22 on Craigslist or e bay still at an afordible cost. Just as it happened with r12 the original installed refrigerant r22 is the best choice.

Thanks Roy. The actual leak location/source has yet to be determined.
