What to do if my TCL Air Conditioner is not cooling properly?
- MMichelle ParkerJul 29, 2025
If your TCL Air Conditioner isn't cooling as expected, consider these possibilities: * Ensure that curtains, blinds, or furniture aren't blocking the front of the unit. * Lower the thermostat temperature. * Clean the air filter. See the maintenance section for instructions. * Allow time for the room to cool down after turning on the air conditioner. * Check for open furnace registers and cold air returns. * If the cooling coils are frozen, switch to high fan speed and set the thermostat to a higher temperature. * Make sure the temperature sensor behind the air filter isn't touching the coil. If it is, reposition it.
