You yourself cant unless you are licensed to do so...
WRONG ANSWER: Anyone can do it if they know how. All you need is the gauges and the proper freon your system is using. My advise to you is be sure you know what you're doing or you can really screw your system up good. The reason someone told you that you need to be certified is in order to purchase the freon you have to have your certification card. There are ways of getting around that though. I have been working on my own HVAC all my life and I'm not certified. I do vehicles at work and homes. I guess this person thinks the air conditioning cops will come and get you if you repair your own system. It's not hard at all just be sure to read up on it first. Good luck. With more people doing their own work on HVAC the rip-off prices will come to a stop.
