I scheduled Sahara Air to give me an estimate on installing a whole-house humidifier. They were pleasant when I scheduled the appointment for 12-4. I was told that I would receive a call from the technician when he was on his way. However, on the day of my appointment, I had two missed calls from Sahara. When I called the office, I was told that Sahara sent my tech to another appointment because I did not call them back. This was 15 minutes after my first call, which was received at 3:30 PM. I asked the receptionist why the technician would not be coming to my home during the agreed upon scheduling time. Her reply was "that we call to see if you are home." There is no reason to set an appointment time if you are not going to hold up to your end of the agreement. I am disappointed with the service that I received from Sahara, and I will be taking my business, elsewhere.
