Carls air conditioning left my family in the cold. I can say they were on time but the technician had a difficult time figuring out why my heat wouldn't turn on. He spent over 1 hour and said it was a switch. That wasn't the problem as that night the temps dropped and the heat didn't work. We have two children's bedrooms that are freezing and our master bedroom. They came back the next day which was on a Saturday and the technician spend over 2 hours to finally tells us it was the board that needed to be replaced. Ok great we'll it's a Saturday and we can't get the part. We'll now my family will be sleeping in the cold for 3 days. Why come on a Saturday if you can't fix anything. The manager was rude and didn't care that my family had to sleep in the cold. I will never use Carls again.
