From the end of 2009 the use of virgin R22 Refrigerant was banned. It is however permitted to use recycled R22 until the end of 2014 for repair and maintenance purposes. Our experience is that supplies of R22 are very short and whatever R22 is available is very expensive. Specific parts for R22 systems are now no longer in production so any parts available are very expensive or often obsolete.


R22 Refrigerant is often found in 2 main categories of equipment – Category 1 (Light Commercial and Domestic) and Category 2 (Industrial and Commercial).

Category 1 systems tend to be contained “leak free” systems such as portable and through the wall Air Conditioning, fridges and freezers etc. these systems tend not to have large quantities of Refrigerant gas and often for a small charge your local council will collect and dispose of them for you.

Category 2 systems tend to be anything from a small single split type Air Conditioning system through to a large process refrigeration plant. The basic guide lines for this type of system are if the system has multiple parts connected or fabricated on site that have a risk of leakage this is a category 2 system. Category 2 systems must have all the refrigerant reclaimed by a qualified engineer who is trained to contain passible leakage during the reclaim process. It is very important the qualified engineer has the correct equipment to reclaim and store the refrigerant until its disposal via the appropriate manner.

Moving forward

All the Air Conditioning systems Chilly Heat provide utilise the refrigerant R410a. R410a was developed by Honeywell in 1991 although its production still contributes to the greenhouse effect the refrigerant has been proven not to have ozone depilating tendencies. R410a refrigerant is a more energy efficient Refrigerant than R22 and therefore saves on the energy bills.
