  Tiffany SmithAug 18, 2025
  If your Senville Air Conditioner starts and stops frequently, it could be due to: 1. Too much or too little refrigerant in the system. Check for leaks and recharge the system with refrigerant. 2. Incompressible gas or moisture has entered the system. Evacuate and recharge the system with refrigerant. 3. The compressor is broken. Replace the compressor. 4. The voltage is too high or too low. Install a manostat to regulate the voltage.
