Air conditioning systems experience various malfunctions due to wear and tear, lack of maintenance, or incorrect installation. One of the most common issues is restricted airflow caused by clogged filters or blocked vents, leading to uneven cooling and increased strain on the compressor. Refrigerant leaks not only reduce cooling efficiency but also pose environmental hazards if left undetected. Faulty thermostats often result in inconsistent temperature control, making rooms either too hot or too cold. Electrical component failures, such as capacitor malfunctions, can cause AC units to stop working abruptly. Addressing these problems early prevents system failure and costly repairs. Regular maintenance and professional servicing ensure a well-functioning HVAC system that delivers reliable performance year-round.
