Technician was to be there sometime in the afternoon. After calling office after 4:00 PM I received a call that he was going to be there at 6:30. When he showed up he said my stairs to attic was only rated at 300LBs and he weighed 360lbs and I could tell he was reluctant to go up. He than asked if there was a floor and when I explained there was a walkway I knew I did not want him walking around up there. He said he would contact the office to reschedule the quarterly service. Have not heard anything yet.
