Air conditioners can develop issues over time, especially during heavy use in summer. Some of the most common problems include low refrigerant, clogged filters, frozen coils, and thermostat malfunctions. Most of these issues can be prevented with regular cleaning and timely servicing. Keeping your filters clean, ensuring proper airflow, and getting professional tune-ups once or twice a year can save you from expensive repairs. Prevention is always cheaper than breakdown fixes, so stay ahead by maintaining your AC regularly.
