Expert Tips for Air Conditioning Maintenance

  1. Regular Maintenance: Schedule routine service calls with a professional technician to inspect and maintain your AC system. They will clean the coils, check refrigerant levels, and identify any potential issues before they become major problems.
  2. Filter Replacement: Replace your AC filter every 30-90 days, depending on the manufacturer’s recommendations and the air quality in your area. A clean filter improves airflow, enhances energy efficiency, and keeps your indoor air clean and healthy.
  3. Coil Cleaning: Dusty coils can reduce your AC’s efficiency. Regularly clean the coils to remove dirt and debris, ensuring optimal heat transfer and cooling performance.
  4. Check for Leaks: Inspect your AC unit for any signs of leaks, such as water pooling or unusual moisture. Leaks can indicate a refrigerant or condenser problem, and a professional technician should address them promptly.
  5. Maintain Air Ducts: Clean and seal your air ducts to prevent air leaks and ensure efficient airflow throughout your home. Properly sealed ducts help your AC system distribute cool air evenly, improving comfort and energy efficiency.
  6. Clear Surrounding Area: Keep the area around your outdoor AC unit free from debris, plants, and other obstructions. Restricted airflow can strain your system and lead to performance issues.


By following these air conditioning maintenance tips, you can fix common AC problems, optimize your system’s performance, and prevent breakdowns.
