Dispatched through my home warranty company, the tech was dispatch 3 day later for - AC unit not keeping up with the high temps of the summer days. The tech arrived and let 2 pounds of refrigerant out of my system and told me I need my liquid line filter dryer replaced, and that he would return another time to complete the work. Over the next 24 hours, I noticed an even more prevalent, lack of cooling in my home. Come to find out the tech let Freon out of my system to further define the low refrigerant issue I already had. My advice is - choose someone else for your repair and/or diagnosis.
