It's that time of year in SA huh? Had our first 90+ day the other day and noticed the AC would not cool well unless on the highway. Vent temp was ~80f. Brought her home, put the can of 134 on there and "topped" up the system. Vent temps vary due to conditions, but got it down to 48f while charging it and stopped there as I did not want to over-fill the system.


I'd suggest topping up your refrigerant first... it's cheap, and usually solves the issue. If you have to do it more than once or twice a summer, the leak should be put on a "to-do" list for upcoming repairs. That's how "I roll" anyway.
