Used this on my 30 year old system last year. I was hoping to get out of the air conditioner for another year before replacing it. All summer long the air remained pleasant and cool, no less warm than usual. I bought another set this year to do the same thing as last year. My AC guy came in to add sealant and charge the system but to our surprise nothing was needed! The system wasn't low at all and still blows nice and cold. The AC guy has been using this stuff since we built my system last year and he's a big fan of it. Definitely worth trying.
