Get a quoteNote:the term "air conditioning" refers to any form of "Heating, ventilation and air-conditioning".This article deals specifically with units used as part of a cooling system. An air conditioner is a system or a machine that treats air in a defined, usually enclosed area via a refrigeration cycle in which warm air is removed and replaced with cooler air.

In order to stabilize the system, put the fan switch in the HIGH position and operate the system for a minimum of 10 minutes. For systems that have air conditioner quick disconnects, the dryer can be removed without recovering the refrigerant.
Get a quoteIt depends what you mean by 'air conditioner'. If it is just an air recirculation system that does not contain a pressure vessel then the answer would be no. However, some air conditioners are cooling systems that could contain a 'relevant fluid' (see PSSR regulation 2 for a definition of a 'relevant fluid').
