    If your Carrier Air Conditioner isn't cooling well, several factors could be the cause. First, check if the temperature setting is higher than the room temperature and lower it if needed. Ensure the air filter and the heat exchangers on both indoor and outdoor units are clean. Remove any blockages from the air inlet or outlet of either unit. Also, close all doors and windows, and reduce heat sources in the room, such as computers or electronics. If the SILENCE function is on, turn it off. Finally, low refrigerant could be the issue; in this case, check for leaks and refill the refrigerant.

    If your Carrier Air Conditioner starts and stops frequently, it could be due to several reasons. There might be too much or too little refrigerant in the system, so check for leaks and recharge the system with refrigerant. Another possibility is that incompressible gas or moisture has entered the system; in this case, evacuate and recharge the system with refrigerant. The compressor could be broken and may need replacement. Lastly, the voltage might be too high or too low, requiring the installation of a manostat to regulate it.

    If your Carrier Air Conditioner isn't heating well, consider these points: If the outdoor temperature is extremely low, try using an auxiliary heating device. Make sure all doors and windows are closed to prevent cold air from entering. Also, check for refrigerant leaks, as low refrigerant due to a leak or long-term use can cause poor heating performance. If necessary, reseal any leaks and top off the refrigerant.
