Men that showed up were rushed, rude, and belligerent in dealing with me. I may be a woman but I am also a landscaper. I know how to run, program, and design systems. I called them because I am super busy and needed my home system checked for leaks. They spent 4 minutes standing in my garage at the program box and said system was okay. They didn't look at each individual head, and then when I questioned that they said they didn't need to because if they pop up then they are fine. DO NOT TRUST THESE GUYS!!!
