I added some Ac Pro to my car but instead of turning the A/C to the max like it said to to I accidentally turned it to the heat to the max well adding the Ac Pro. I was wondering if that will damage the car in anyway or anything?

Welcome to 2CarPros.

It won't hurt anything. However, the A/C needs to be on max to engage the compressor. Chances are the pressure that you saw on the gauge was indicating a pressure that was with the compressor off (since the heat was on). I would reconnect it and with the A/C on high, see what the pressure is.

Let me know what you find.

Take care,
