Why should owners of air conditioning using R22 refrigerant consider replacing it?
Any air conditioning over 10 years old probably uses R22 refrigerant, an ozone-depleting CFC which was banned in most new systems in 2002. By EU law R22 systems will become unserviceable at the end of 2014, meaning that it will be illegal to repair them in the event of any failure. It is not economical to repair the systems as spare parts and recycled R22 are expensive and in short supply.
Modern replacement systems use more environmentally friendly refrigerants and are up to 60% more energy efficient than R22 systems, meaning that owners often pay back replacement costs in energy savings alone within 3 or 4 years.
