I know this thread is almost a year old but I'm digging it up anyway.

A few weeks ago I noticed the A/C in my daily driver just wasn't blowing as cold as it should any longer so I picked up a recharge canister made by InterDynamics. I heard about it on the forum I frequent for that particular car and last week I met the folks from ID at the Advance Auto Parts Manager's Conference. They were telling me that they're struggling to get people to accept this as a DIY process even though you can do for more easily than changing your oil (which has a very high DIY rate) and save a heck of a lot more money in the process than you do with a DIY oil change.

I understood completely - I change my own oil and always have, dating back to my first car in the late '70s. But this was my first experience with recharging an A/C system, although I've paid in excess of $100 previously with other cars. The operation was quite simple with this $30 canister/gauge package, and my A/C has been blowing ice cold ever since. For those of you with 2004 or 2005 MY cars that may be seeing a reduction in cold air output from your A/C, I highly recommend this product for a quick DIY fix that will save you time and money.
