Sorry mate but I completely disagree.
R410a systems are much better, and for the environment as well. As long as your pipe work does not exceed 5/8 the old copper "SHOULD" be fine.
Just remember to have a pro do the job and make sure he fushes the old oil and crap out if the pipe. Don't get dodgy dave refrigeration serives to do the job.
R22 is a HCFC and is nasty to the environment. The next phase of refrigerants you'll see coming on the market will be CO2. In 6 yrs time cola-cola amital will only use merchandisers which run on CO2.
