Thank you Air Maker and Shabnam for your excellent customer service !
Our AC was down on July 21, a recording breaking weather temperature day unfortunately. I could't find the real problem, so I called Air Maker who installed the AC four years ago. It was 4:30 pm already , for such a short noticed request , my expectation for a quick fix was low, worried it would be a sleepless night without AC. To my surprise, Shabnam called me back within a few minutes, after knowing the main failure symptoms she kindly arranged a technician visit at 7 PM ! A technician arrived my home on time, a friendly and informative young man. He made a quick diagnosis of the whole AC system, found the issue was not with AC but with the defective thermostat. He helped to replace a new thermostat and the problem was solved, our AC started working again ! We had a sound sleep that night.
I highly recommend Air Maker to everybody, for its fantastic Customer Services.
