how often should i have my air ducts cleaned

As a homeowner, there are plenty of things to stay on top of; homeowner’s insurance, property maintenance, storm preparedness, the list goes on and on. As if that doesn’t keep you busy enough, you also have to make time for AC maintenance to ensure that your air conditioner works efficiently and lasts as long as possible. Part of that maintenance includes cleaning the air ducts.

How Often Should You Clean AC Air Ducts?

The National Air Duct Cleaners Association (NADCA) recommends that you clean the ducts every three to five years. Factors that influence that timeframe include:

  • The amount of pollution in your geographical area
  • How many people live in your home
  • Whether anyone in your household smokes
  • Whether anyone in your home suffers from allergies

Benefits of Cleaning Air Ducts

In order for an air conditioner to work efficiently, airflow needs to be unobstructed. This will help your system reach the temperature set on the thermostat quicker, which translates into energy efficiency and lower utility bills.

In addition, clean air ducts reduce the likelihood of mold formation, and the accumulation of allergens, they also prevent insects and rodents from nesting inside your home.
