Maintaining Air Conditioning Systems in your Block of Flats

Air conditioning regulations for blocks of flats

Up until 2001, air conditioners would mostly use a HCFC (Hydrochlorofluorocarbon) called R22. Although R22 is an effective refrigerant and can absorb a great deal of water, it was discovered to have a negative impact on both the environment and people exposed to the gas over long periods of time.
RSS regulations:

• As of 2001, the UK government has banned the production of new air conditioners which use R22 refrigerant gasses.
• In 2015 it was declared illegal to maintain or service air conditioners with R22 gas.
• Although it is still legal to use HCFCs in your old air conditioner, a service technician cannot break into the circuits to fix your system.
