Your unit isn’t cooling properly
Your refrigerant could be low or leaking. Call a trained technician to repair the leak and recharge the system.
If you have a window unit, the thermostat sensor could be knocked out of position. Carefully bend the wire holding it in place to properly position it.
Check Your thermostat to make sure it is set properly and it is reading the correct temperature.
Check Your unit’s drain to make sure it isn’t clogged.
A clogged filter restricts airflow through the unit, decreasing its efficiency and reducing its ability to effectively cool the air.
