Time to recharge the AC?
Used the AC for the first time this year just to see how it worked. The outside temperature here today was 80, but it felt like the car just wasn't cooling down too well. In used a thermometer to test how cold my air was coming out of the vents, and it was at 49 degrees after 20 minutes of driving. I thought this was too warm, so I tested both of my parent'* vehicles (2001 Silverado, 2000 SSEi) and both of them had air vent temperatures of 35 degrees after only 5 minutes of driving. I'm assuming I'm in need of a recharge? If so, can I just buy one of the 'recharge' kits that they sell at say, autozone? If so, that'd only be around a $30 job. Do you have to have the system "evacuated" professionaly like the R12 systems? Thanks for the help! it'd be nice to have nice and cold AC for the hot summer!
