    What to do if my CLIVET Air Conditioner has poor cooling performance?

      If your CLIVET Air Conditioner isn't cooling well, it could be due to several factors. First, ensure the temperature setting is lower than the room temperature. Other potential causes include a dirty heat exchanger (clean the heat exchanger), a dirty air filter (remove and clean the filter), blocked air inlet or outlet (turn the unit off, remove the obstruction, and turn it back on), open doors and windows (keep them closed), excessive heat from sunlight (close windows and curtains), or low refrigerant (check for leaks, re-seal if necessary, and top off refrigerant).

      Joanna SmithAug 13, 2025
      If your CLIVET Air Conditioner is not heating well, it could be because the outdoor temperature is lower than 7°C (44.5°F). Other causes include cold air entering through doors and windows (ensure they are closed) or low refrigerant due to a leak or long-term use (check for leaks, re-seal if necessary, and top off refrigerant).

      Elizabeth JohnsonAug 20, 2025
      Your CLIVET Air Conditioner might not be working due to several reasons: a power failure (wait for the power to be restored), the power switch being off (turn on the power), a burned-out fuse (replace the fuse), dead remote control batteries (replace the batteries), or the unit’s 3-minute protection being activated (wait three minutes after restarting the unit).

    Why does my CLIVET Air Conditioner start and stop frequently?
    • J
      Jessica DayAug 27, 2025
      Your CLIVET Air Conditioner might be starting and stopping frequently due to several reasons: * Too much or too little refrigerant in the system (check for leaks and recharge the system). * Air, incompressible gas, or foreign material in the refrigeration system (evacuate and recharge the system). * A blocked system circuit (determine which circuit is blocked and replace the malfunctioning piece of equipment). * A broken compressor (replace the compressor). * Voltage that is too high or too low (install a manostat to regulate the voltage).
