Why is my Carrier 42QHG018D8S Air Conditioner not cooling properly?
- TTara EatonJul 26, 2025
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.
