DO NOT USE A/C PRO!!!

[SirDigby]

this is a warning: DO NOT USE A/C PRO! It will ruin your a/c system and cost you thousands of dollars!
A/C pro contains stop-leak. stop-leak is aerobic, meaning it reacts with oxygen. when it reacts it becomes rock hard.
if your system has a leak, r134a has exited the system, and outside air has entered in it's place. this means EVERY COMPOINENT HAS OXYGEN CONTAMINATION. If you do not pull the system into a deep vacuum before using this product, (remove oxygen from system) every item in the system will be covered with stop leak and will become rock hard and will not function. this means that EVERY COMPOINENT WILL HAVE TO BE REPLACED. compressor, condenser, evaporator, expansion valve, sensors, lines, receiver/dryer, FOT's, etc. EVERYTHING!
do not try to save $150. you will cost yourself $4000
