London Air Conditioning
Our air Conditioning engineers were called to an air conditioning system failure in London. This would not be worthy of a case study due to it being a common every day occurrence but there is an important issue to be raised.
The air conditioning system was reported to be not providing heating or cooling which was the sole system for these functions within the building, and so was an urgent requirement. The external units are situated on the roof at height and therefore required a tower to be erected to gain access. The Air Conditioning system fault was soon diagnosed as there being no refrigerant gas within the system. So the engineers carried out the visual checks to see if there was any failures causing the refrigerant gas to escape which there was not. So the system then under went a series of tests one being a pressure test of the air conditioning system which passed.
Following all the required tests and procedures required to re gas the air conditioning system new R407C gas was installed. The system was fully tested and back in full working order.
R22 Refrigerant Gas
Now the question to be raised is what would happen in 12 months time if the system has used R22 refrigerant gas ? The outcome would be completely different as from the end of 2014 air conditioning systems using R22 refrigerant cannot be re-gassed. Unfortunately its not a simple case of using another refrigerant gas the system may be totally unusable requiring a new air conditioning system installation.
If your Air Conditioning system uses R22 refrigerant gas now is the time to consider your options.
