We have had shamrock come out to fix our a/c four times now in less than 3 weeks. They fixed it the first time, had the same issue a week later which a technician bypassed something in order to allow us to use it while the part got ordered and returned and fixed what they thought was the issue. Now the fourth time he was not able to fix it recommended we keep it off and couldn't tell us when they can come back. We are now without ac for at least the weekend and couldn't even get an answer on when they could return because the scheduling department handled that and no one answers the line, not even an emergency option. I don't normally write reviews however an ac company should be a little courteous to their customers during the 100+ temperatures. Would not recommend simply for leaving us hanging with absolutely no follow up.
