With the still sun making an appearance these days, I thought it time to get the air-con re-gassed; as it seemed to be pretty much useless when turned on.
 
This machine first checked the system for leaks, then extracts out any remaining oil and gas, then refills it.
 
Good news, no leaks in the system.
 
and the reports suggests over time it had evaporated away. But with a re-gas up to 700g, all is cool again 🙂
