My in-laws purchased a kenmore air conditioning unit, model r-410a about 5 years ago. It worked great for the first summer, but they have had nothing but problems with it ever since. The last 4 years Sear's technicians have come out and simply refilled the freon supply but never checked for leaks or cracks in the system. Finally 4 weeks ago the unit stop working again. Sears was called out and a technician named Ignacio determined that there was a large crack in the unit and it was leaking large amounts of freon. He stated that sears had stopped making this model because several of these units were going bad. So ignacio ordered the part and said he would return in 5 days. Well its been 4 weeks. He came back today fixed the cracked piece but then stated that the fan was bad and it would take 10 days to get the part!!! My father in law is terminally ill and housebound, my mother in law is incapable of getting this taken care of so i am stepping in. The service has been beyond horrible and no thought has been given to the ocuupants who need their home cooled. They need a new unit installed NOW!!!
