Air ducts are responsible for carrying heated and cooled air throughout the home all year long. While they require very little attention from homeowners, they do occasionally need cleaning to ensure their effectiveness and the quality of indoor air. Here’s how to know when it’s time to book an air duct cleaning for your home. 

How to Know Your Air Ducts Need Cleaning

1. Consistent Allergy Symptoms

HVAC systems rely on filters to help catch and remove dust, dirt, and pollen from the air. However, they’re not able to collect all the contaminants as they pass through, which can allow them to build in the ductwork over time. Temperature differences between the ducts and the air surrounding them, like in the attic, can cause condensation, resulting in mold and mildew growth. 

When air is forced through, it can push some of these particles out into the home. As a result, residents may experience allergy-like symptoms, like sneezing, coughing, and itchy eyes, especially if they’re sensitive to such elements. Cleaning the ducts every three to five years helps remove this buildup to improve indoor air quality. 

2. Rising Energy Costs

If left long enough, accumulation of debris can end up creating a blockage and limiting airflow. As a result, the system attempts to work overtime to compensate for the temperature fluctuations within the home. 

The increased energy usage can lead to rising utility costs, especially during peak temperatures in the summer and winter. For that reason, air duct cleaning can end up saving the homeowner a significant amount of money in the long run. 

3. Recent Renovation

From new flooring to removing walls, home updates can transform a space in a matter of days. However, these projects can end up producing dust and construction debris that gets trapped within the ductwork. As such, additional duct cleaning after home projects is often a necessity.
