Here’s what to check if AC is not cooling,
Dirty Air Filter: A clogged air filter blocks airflow. When air cannot flow freely, the AC cannot cool the room well. Clean or replace the filter regularly to keep the AC working efficiently.
Dirty Condenser Coil: The condenser coil is outside the unit and releases heat. Dust, leaves, and dirt can cover the coil and stop heat from escaping. Clean the coil to improve cooling performance.
Low Refrigerant Level: Refrigerant is the gas that cools the air. If there is a leak or low gas level, the AC will not cool properly. Call a technician to check and refill the gas.
Frozen Evaporator Coil: The indoor coil can freeze if airflow is blocked or the AC runs too cold. Turn off the AC and keep the fan on to melt the ice. If the problem continues, contact a technician.
Faulty Thermostat: The thermostat controls the temperature. If it sends wrong signals, the AC may not cool correctly. Check the settings or replace the thermostat if needed.
Compressor Problem: The compressor pumps the refrigerant through the system. If it fails, the AC will not cool or may not turn on. A technician must repair or replace the compressor.
AC Unit Too Small: If the AC is too small for the room size or climate, it cannot cool the space properly. Choose the right AC capacity based on room size and weather conditions.
These are the main things to check when your AC is not cooling. Regular cleaning and timely servicing can prevent most problems and keep your AC running smoothly.
