Moving house can be a very exciting time for many, especially those who are leaving their parents home for the first time. For others, it is an unfortunate consequence of the recession, with many renting their own home and moving to smaller properties. What both groups have in common is their haste, and this is what makes them vulnerable to landlords who do not comply with current UK gas safety legislation. At the end of 2014, R-22 refrigerant will be banned under EU legislation. So air conditioner systems with R-22 gas will effectively become redundant as any loss of gas cannot be replaced. It is estimated that there are still millions of R-22 systems still in operation, but the main reason for businesses delaying implementation of R-22 replacement systems is, putting it simply, the expense.
