A/c Not blowing air inside
A/C Unit not blowing air inside. It does get cold or hot depending on if I set the t stat to a/c or heat it just doesn't blow air at the vents. Outside unit turns on. I use 3 month filters and last changed it 3 days ago. I cleaned cold air intake vents. I don't see anything really strange but it still won't blow. I have turned off unit and turned on the fan as I saw suggested in other posts. Landlords say if it is something we did we have to pay for it. This unit has never been serviced nor have the ducts been cleaned in the 8 years we have been here. Could it be something we did that caused this?
