AC Maintenance: 5 Techniques to Keep Your Air Ducts Clean

Air conditioning is a necessary service in the hot summer months. However, a poorly maintained AC system can lead to dirty air ducts, which can cause health problems and increase energy costs. Air ducts are responsible for circulating air throughout your home. It’s important to keep them clean to ensure good air quality and the longevity of your AC system.

Here are five ways to keep your air ducts clean longer:

1. Change Your Air Filters Regularly

The air filters in your AC system collect dirt, dust, and other particles that float around in the air. Over time, the filters can get clogged, reducing your AC’s efficiency and increasing your energy bills. Additionally, dirty air filters can cause pollutants and allergens to circulate in your home, harming your health.

To keep your air ducts clean, changing your air filters regularly is important. Experts recommend changing your filters every 90 days, depending on your usage and filter type. You can also invest in high-quality air filters that capture smaller particles and improve air quality.

2. Keep Your Home Clean

Dust and dirt can accumulate in your home quickly, especially if you have pets or kids or live in a high-traffic area. The more dirt and dust you have in your home, the more it will circulate through your AC system and into your air ducts.

To prevent this, it’s important to keep your home clean. Vacuum regularly, dust surfaces, and clean your floors. You should also avoid smoking indoors and limit the use of candles, which can release pollutants into the air.

3. Seal Your Ducts

Leaky air ducts can cause your AC system to work harder to cool your home, leading to higher energy bills and a shorter lifespan for your AC system. Leaks can also allow dirt and dust to enter your ducts, reducing air quality and increasing the need for AC repair.

To prevent leaks, it’s important to seal your ducts properly. You can use duct sealant or tape to seal any gaps or cracks in your ducts. You should also check your ducts regularly for signs of leaks, such as dust or debris around the ducts.

4. Schedule Regular AC Maintenance

Regular AC maintenance is essential for keeping your air ducts clean and your AC system running efficiently. During routine maintenance, a professional AC repair technician will inspect your system for any issues and clean your ducts to remove any dirt or debris.

Regular maintenance can also prevent costly AC repairs in the future. A professional technician can catch any issues before they become major problems and help you extend the lifespan of your AC system.

5. Invest in an Air Purifier

An air purifier can help improve air quality and reduce the need for AC repair. An air purifier can capture pollutants and allergens that circulate in your home and prevent them from entering your air ducts. This can help reduce the dirt and debris that collects in your ducts, leading to cleaner air and a longer lifespan for your AC system.


Keeping your air ducts clean is essential for good air quality and the longevity of your AC system. By changing your air filters regularly, keeping your home clean, sealing your ducts, scheduling regular AC repair and maintenance, and investing in an air purifier, you can keep your air ducts clean and get them running for longer.
