With a set of manifolds and a vacuum pump from Harbor Freight, you can do this repair yourself. Also had to buy an adapter to better puncture the cans to add refrigerant from Amazon or O'Reilly Auto.
I just bought a set of their gauges and I am having issues with the adaptor I bought and what seems to be a resealable can of refrigerant. Works like crap. Not sure if I got the wrong adaptor or what. The gauge kit is nice, got it on clearance.
