Inadequate cooling: This can occur due to various reasons, such as insufficient refrigerant levels, dirty or clogged air filters, or malfunctioning components like the compressor or condenser.
Airflow issues: Restricted or inadequate airflow can result in reduced cooling efficiency. It can be caused by dirty or blocked air filters, obstructed vents, or damaged fan blades.
Water leakage: Window AC units produce condensation, which is typically drained outside through a condensate drain. If the drain is clogged or the unit is not properly installed, water may leak inside the room.
Noisy operation: Window AC units can generate noise due to various factors, including loose or damaged components, faulty fan motors, or compressor issues.
Electrical problems: Faulty wiring, loose connections, or issues with the power supply can lead to electrical malfunctions in the window AC, causing it to not operate properly or fail altogether.
Thermostat problems: A malfunctioning thermostat can result in inaccurate temperature control, leading to insufficient cooling or excessive energy consumption.
