If your air conditioner is running, but the space is not cooling as expected, it could be due to several factors. First, check if the air filter is clogged, as this can restrict airflow and reduce the unit's efficiency. Dirty coils or low refrigerant levels can also be the cause of poor cooling. It’s important to check both the evaporator and condenser coils for dirt or debris. If the refrigerant is low, the system will not be able to absorb or expel heat properly, and a technician will need to recharge it. Another possible reason is a malfunctioning thermostat. If the thermostat is not reading the temperature correctly, it might not signal the AC to cool the air effectively. If the thermostat is damaged, it should be replaced to ensure proper operation. Make sure the thermostat is properly calibrated and located away from heat sources such as windows or lamps.
Keep your AC coils clean and replace the air filter every couple of months to avoid poor cooling. Additionally, have a professional inspect your system annually to ensure it’s working efficiently.Regular maintenance can help ensure your AC cools your space effectively and reduce the chances of these problems occurring.
