A quick question. I am a homeowner in NJ. I've been told by my heater repairperson that my AC will need to be replaced in 2010 as the refrigerant it uses, R22, will no longer be available from Jan 2010. A friend of mine tells me that R22 would still be available until 2020 and the ban refers to the fact that no new units could be fitted using R22. If the latter is the case and R22 remains available at a reasonable price for a few more years, then it would make no sense for me to replace the unit as I need to move within 2 years. Could you please clarify the above matter? Thanks in advance for any advice.
