What Causes Your AC to Freeze During Hot, Humid Days?
Seeing frost on an air conditioner when Manor is sitting near 98 degrees can be confusing. Nothing outside is remotely close to freezing, yet the larger copper refrigerant line may turn white with frost, the indoor evaporator may become coated in ice, and the airflow from the vents can steadily disappear. Before long, the AC is still running but the rooms are getting warmer instead of cooler. ATX Heating & Air Conditioning LLC handles these freeze-up calls throughout Manor during the summer because outdoor heat does not prevent the indoor coil from dropping below 32 degrees.

During normal operation, the surface of that coil commonly stays in the mid-40-degree range. It is cold enough to cool the air and condense moisture but warm enough for that moisture to remain liquid. Under healthy ...
