Spring is over, and it's time to start using the a/c while I drive, but when I tried to use it for the first time this year, it wasn't cold. Room temperature at best. I decided to try recharging it myself with A/C Pro.
I checked to make sure the compressor was turning. It was. I turned my a/c all the way to maximum, and started to recharge. The pressure was super low according to the a/c pro gauge. After a while it was getting into the green area, but then the pressure started dropping again. Eventually the can of freon was empty, so I stopped. The compressor was still fine, no funny business suggesting that I overcharged the a/c. I checked the air blowing inside my car, and it was definitely colder, but not really cold like it used to be :-(
When I turned my car off to start cleaning up, I noticed I could hear a hissing sound from under the hood. I turned my car back on and noticed I could hear it a bit in the car as well.
I guess I'll know tomorrow if the freon leaks out and my a/c doesn't work again, but in the mean time, could there be a problem here? I considered using Super Seal and then putting in more freon. Would this be a bad idea? I'd really like to avoid a trip to the mechanic.
