How Often Should You Schedule AC Coil Cleaning?

AC coil cleaning is one of the most important maintenance tasks for keeping your cooling system running efficiently. Over time, dust, dirt, and moisture build up on your coils, reducing airflow and forcing your AC to work harder than necessary. But how often should you actually schedule AC coil cleaning?
For most homes, AC coils should be professionally cleaned at least once a year. Annual cleaning ensures that your system stays energy-efficient, cools your home properly, and avoids unnecessary strain on the components. If your AC runs heavily during hot months especially in regions with frequent dust or humidity you may benefit from cleaning the coils every 6 months.
Homes with pets, allergies, or high indoor dust levels should also consider more frequent maintenance. Dirty coils not only reduce cooling performance but can also affect indoor air quality, making your AC less effective and more expensive to run.
Regular AC coil cleaning helps prevent breakdowns, improves energy efficiency, and extends the lifespan of your system. Whether you choose yearly or twice-yearly maintenance, staying consistent is the key to a healthier, smoother-running AC unit.
