Weather King contact info

Question

Our AC unit is not working, a local technician came and concluded we need to have the compressor replaced and he said it should still be under the original 10-year warranty. But I was not able to locate any contact/support phone number in the origianl installation guide (that's the only document I have related to the AC) we got from the builder when we moved in 5 year ago. Does anyone know how/who to contact (Weather King) in a situation like this?
