Can you recharge an air conditioner with refrigerant?

You personally? Probably not ... but an Air Conditioning mechanic, by all means, yes.

This is not a Do-It-Yourself job.

Because refrigerant gas is very dangerous to handle - you could suffocate yourself or someone else in the room - you need to have the right tools and test equipment and must have been trained so that you know what you are doing.

Any appliance that contains refrigerant gas - such as an air conditioner unit or a refrigerator - which has developed a fault must be thoroughly checked by an expert to ensure that a) it is running safely and b) there are no leaks of refrigerant gas.

The only advice anyone should give you is to call a Licensed Heating, Ventilation and Air Conditioning (HVAC) Technician to do this job for you.

For personal safety reasons only technicians who are licensed to work on HVAC (Heating, Ventilation and Air Conditioning) should do this kind of work because they have the right test equipment and tools and have been trained in how to do this work safely.
