Air standards has been extremely hard to work with. Two technicians have come out in the past week, and have been unable to fix or address any issues. Our A/C has not been running at all for over a week, and we were told that the company would reach out to us after our last appointment to set a new one. Never heard back, and left several voicemails with no response. Extremely disappointed- it is summertime in AZ and they have zero sense of urgency or lack of respect for their wrong diagnosis'!!
