A broken AC fan leaves your system running without moving air, and in a Texas summer you feel it within the hour. If the fan stops, the cooling stops. Call a technician from Thayer Air Conditioning before the heat builds up inside the house. Key Points Why Did My AC Fan Stop Working? A broken AC fan means your system cannot circulate cool air, and the house heats up fast. Prompt AC repair gets the unit running again and gets you back out of the heat. The Two Vital AC Fans Your AC runs two fans, one in the indoor unit and one in the outdoor unit. Both are essential. If either breaks, you have no cooling.
