I am writing because was deeply unsatisfied with my recent service of my Central AC unit on 10/4. Let us start from the beginning. I had first done my annual maintenance check up that is part of my protection agreement in mid to late August. After that visit my pregnant wife (has since delivered) and I notice slowly a certain order coming from the AC when it was running that grew stronger as the days went by. I then called again to schedule an appt to have a tech look and the unit which was originally scheduled for 9/28 but that was cancelled by sears because of weather. so It was rescheduled to the 4th of October. So I get a call the day of my service from the technician, Erik, who proceeded to drill me with so many questions almost as if I was making things up. Its as if he was looking for any excuse to not come. He finally shows up and after asking me for the manual to the unit he proceeds to read it. He took the cover off the electronic filter and then proceeds to bend these metal flaps all the way back. He completely bends these into the unit, which I assume is not supposed to happed as technicians prior didn't have any issues with them. he then went to his truck and after a little while he came back in and told me that. the problem was that when Sears installed the unit they installed it improperly. the electronic filter is not supposed to be plugged into an outlet that is on 100% of the time. The manual says doing so can lead to overproduction of Ozone. when I checked multiple resources exposure to Ozone can be fatal and cause many respiratory complications, ESPECIALLY IN PREGNANT WOMEN AND UNBORN CHILDREN. as I stated earlier my wife is pregnant (has since delivered) so this is extremely unacceptable. When we first bought our house in 2009 we started to only buy strictly Sears products because the service experience had always been great. It is sad to say that it is not the case anymore.
