  Several factors can cause poor cooling performance. The heat exchanger on the indoor or outdoor unit might be dirty; clean the heat exchanger after removing the filter. Obstructions in the air inlet or outlet can also be a cause; turn the unit off, remove any obstructions, and then turn it back on. Ensure all doors and windows are closed. Close windows and curtains to reduce excessive heat from sunlight. Reduce the number of heat sources in the room. Finally, low refrigerant levels can be a factor; check for leaks, re-seal if necessary, and add refrigerant.

  If your unit isn't working, there could be several reasons. Check for a power failure and wait for the power to be restored. Make sure the power is turned on. Replace the fuse if it's burned out. If the unit’s 3-minute protection has been activated, wait three minutes after restarting the unit. Also, ensure the timer is off.

Why does my Cooper & Hunter Air Conditioner start and stop frequently?

  Frequent starting and stopping can occur if there’s too much or too little refrigerant in the system; check for leaks and recharge the system. It could also be due to incompressible gas or moisture in the system, requiring evacuation and recharge. A blocked system circuit can also cause this issue; determine which circuit is blocked and replace the malfunctioning component. Alternatively, the compressor might be broken and need replacement, or the voltage may be too high or low, requiring the installation of a manostat to regulate it.

  If you're experiencing poor heating performance, it could be due to extremely low outdoor temperatures; in this case, use an auxiliary heating device. Ensure that all doors and windows are closed to prevent cold air from entering. Also, check for low refrigerant levels due to leaks or long-term use; inspect for leaks, re-seal if necessary, and top off the refrigerant.
