Are they any good? I was down in Calais, Maine today and looking around the Walmart there. Ah, the oil selection! Anyway, I happened to notice these DIY A/C recharge kits. Only 20 bucks, and it comes with the little hose too. Bottle included the refrigerant, compressor oil, and other stuff. I notice the A/C on the wagon isn't terribly cold, so I figured maybe I'd give one of those kits a try sometime. the wagon is a 1990, but I'm pretty sure it was converted to run R-134a sometime in 99, according to a receipt I found. It was recharged in 99, and I would assume with R-134a. Enough about that, does anyone have any experience with these kits? If I could get one of these kits for something like $30 Canadian (depending on exhange) and recharge my A/C system, I'd be pretty happy. Just a basic A/C system checkup around here is 45-50 bucks, and a recharge would probably be at least that much. If these kits are any good, I'll make a run down across the border and get one, and maybe pick up some Supertech oil filters while I'm there. One more thing, why don't we see these DIY kits anywhere in Canada?
