Air duct cleaning: why it’s important and why you may need one

Duct cleaning refers to the process of cleaning the ductwork inside a house or a building using a high-power vacuum and professional tools. Duct cleaning can improve indoor air quality and lower your utility bills by increasing airflow and optimizing your furnace’s performance.


Why should I schedule a duct cleaning?

The extensive build-up of dust, grime, and particles in your ducts lead to restricted airflow. When airflow is restricted throughout the home, you might experience warm and cold spots and inconsistent temperatures throughout the house. 

Modern HVAC systems detect when the air has reached its desired temperature and adjust accordingly. When there’s a blockage in your ducts, your system might run for much longer than it should, which can result in a higher utility bill. 

Furthermore, dust can blow into other rooms and cause poor indoor air quality. Scheduling a professional duct cleaning ensures that your HVAC system runs efficiently and contributes to a more comfortable environment.

When should I get my air ducts cleaned? 

Most HVAC service companies in Calgary will recommend scheduling a professional duct cleaning once every two to three years. If you have pets or a member of your household smokes, duct cleaning should be performed more frequently. 

However, if any of the following issues arise, call your HVAC technician as soon as possible. They can assess if there is a blockage in your ducts and check your furnace to see if it’s working at an optimal level. 

  • You notice dust particles spewing out of the vents.
  • There is inconsistent airflow in some areas of your house.
  • There is little to no airflow coming out of one or more vents.
  • A musty smell is coming from the vents, which could indicate mould.
  • You suspect that there are mice or insects in the ducts.
  • You suspect that an object has fallen into the ducts.
  • You’re experiencing higher than usual allergy symptoms.

Another reason to schedule a professional duct cleaning is if you’ve had a major renovation or if you’re moving into a newly built house. Combined with regular furnace maintenance, having your ducts cleaned helps keep your HVAC system running efficiently and increases the lifespan of your furnace.
