The first time my husband contacted AMS was a few weeks ago to get our sprinklers fixed. The first guy who came out was not familiar with the system so they had to reschedule and bring somebody different. Regardless, my mother in law gave the first guy instructions and told him specific instruction on what needs to be done on certain sprinklers (which sprinklers need to be shut off, need to be turned on etc.), she was happy since this guy was writing everything in his notes.
The second guy came and "fixed" some of the sprinklers, only for us to find out that they were not working. We had to call last week (or the week before) to ask them to re-check everything since the sprinklers were not going off.
The third guy came out and made the sprinklers come off, however, still did not work on the sprinklers that needed to be shut off and the ones that need to be turned on.
