Its about a year old, at most. I replaced it before, and then i broke my condensor. So its been sitting with a open system for maybe a month, hten I taped it up in hopes i would save it. Then I bought a new condensor, put it in and tried to recharge my system when the shrader valve on my a/c line wont close right so it leaks a little. Im gonna buy a new compressor, a/c line and get it charged and I wanted to know if I should get a new dryer too. Its sickening, i havent had a/c in a year in a half but ive been through 3 condensors, 2 a/c lines and a dryer already. Now I need another a/c line and a compressor. A/C is a pain in the ass!
