R22 is found in older air conditioning systems normally pre 2000 and this has been phased out and was banned from the 1st January 2015 therefore making the equipment non serviceable. This could be potentially catastrophic if, for example, your system is being used to cool a server room. In the case of system failure, the system will be non-repairable. Focus Air Conditioning offer R22 replacement solutions including equipment upgrades to current more efficient refrigerants such as R32 or R410A. The latest equipment from leading manufacturers will have the updated modern controls and we are able to offer up to 7-year warranties.
