Could be a lot of reasons. Mine was a starter unit for the A/C. Honestly, it's worth having One Hour come out to make sure, as the unit is quite expensive, and you wouldn't want to waste that money without getting it fixed.
Hi Amanda, There are many reasons that could cause your air conditioner to blow hot air. Typically, if your air conditioner is blowing hot or warm air, it's likely an issue with low refrigerant or the compressor unit. Please give us a call at (864) 303-1451 if you ever run into this issue again. We answer calls 24/7 so you can have your emergency service problems solved right away. Charles Crumpton, Owner/Operator
