Be aware that prices of R-22 refrigeration may increase while supplies will likely wane. After January 1, 2010, original equipment manufacturers will no longer be able to sell equipment using R-22. The phase out of R-22 will be a lengthy process and market conditions may not be as greatly affected by the volatility that resulted in refrigerant price hikes characterized by the phase out of R-12.
Existing equipment using R-22 can continue to be serviced with R-22. However, chemical manufactures will no longer be able to produce R-22 after January 1, 2020. After 2020 the servicing of existing equipment will rely exclusively on re-claimed and recycled supplies of R-22.
If your equipment is more than ten years old, you may save significantly on your cooling energy cost by replacing it with a new more efficient model using R-404a or Scroll compressor technology.
Energy efficiency, system performance, hourly run time of equipment, reliability, and actual cost to operate (amp draw, run time, etc.) should be considered when deciding to purchase new equipment.
To help speed the transition away from ozone depleting refrigerants, choose a system that uses ozone friendly refrigerants.
