Air Duct Cleaning Explained

First things first, what exactly is air duct cleaning? Air duct cleaning is the process of removing contaminants like dust, dirt, mold, and other pollutants from the ductwork of your heating, ventilation, and air conditioning (HVAC) system. It can help improve the air quality in your home or building and ensure your HVAC system runs efficiently. Plus, it can also help reduce the risk of respiratory problems, allergies, and other health issues associated with poor indoor air quality.

The Best Time to Schedule Air Duct Cleaning

Now, when is the best time to schedule air duct cleaning? We recommend spring or fall. You’re less likely to rely on your HVAC system for heating and cooling during these seasons, which means you won’t be disrupting your daily routine by having your ducts cleaned.

Signs of Dirty or Clogged Air Ducts

How do you know when it’s time to clean your air ducts? Look out for these signs from the National Air Duct Cleaners Association, or NADCA:

  • Musty odors coming from your vents
  • Dusty surfaces in your space
  • Rodents or insects in ducts
  • Increased energy bills due to reduced HVAC system efficiency
  • Newly renovated or constructed homes

If you notice any of these signs or experience inconsistent temperatures throughout your home, your air ducts could be to blame. If anyone in your household suffers from allergies or respiratory problems, cleaning your air ducts to remove any potential irritants is essential.

How Often to Clean Your Air Ducts

So, how often should you clean your air ducts? It depends on several factors, such as the age of your HVAC system, the number of occupants in your home, and your air quality. Generally, it’s recommended to get your air ducts cleaned every three to five years. However, if you have pets, smoke inside your home, or suffer from allergies, you may need to get your air ducts cleaned more frequently.

Types of Air Duct Cleaning

There are several types of air duct cleaning, including source removal cleaning, negative air cleaning, chemical treatment cleaning, and biological control cleaning. The effectiveness of each method can depend on the specific circumstances and the type of contaminants present in the ducts. It’s best to consult a professional air duct cleaning service to determine the most appropriate method for your situation.
