Why Your Air Ducts Should be Cleaned Professionally

If the air ducts in a residence or business look dirty, they probably are, and should be cleaned by a professional company. Cleaning dirty air ducts frequently reduces indoor pollution (that can cause health problems), reduces energy use and may prevent unexpected disasters, as well as costly repairs.

The main reasons to clean air ducts:

  • Reduce indoor pollution and health risks
    • Each year, up to 18 kilograms of contaminants (dust, chemicals, dander, etc.) are created in a 6-room residence through everyday living. These contaminants are pulled into the heating, ventilating and air conditioning (HVAC) system, and recirculated 5 to 7 times a day, on average. As a result, a build-up of contaminants in the ductwork is created over time.
    • Having a clean and properly functioning HVAC system is important for maintaining a good level of air quality and a healthy living environment.
    • Individuals who suffer from allergies, asthma or other respiratory diseases may risk aggravating their condition if the ducts are polluted with contaminants.
  • Save energy
    • If the ducts are clogged with dirt and other contaminants, between 25 to 40 percent of the energy used for heating or cooling may be wasted.
    • Although filters block some of the pollutants that would otherwise get into the ducts, the ones that do enter will cause the heating and cooling system to work harder and consume more energy. If the HVAC system is clean, it works more efficiently and consumes less electricity.
  • Other reasons
    • Duct cleaning is necessary when there is a substantial amount of mould inside the ducts. Mould spores may be released into the building, affecting the health of the occupants.
    • If vermin, such as rodents or insects, live in the air ducts, a pest control company should be contacted immediately.
    • The air ducts should be cleaned after a home renovation, when a significant amount of debris, dust and other particles (especially asbestos and lead paint) have migrated into the air ducts.
    • It is advised to service the heating system (fuel burning furnace, stove or fireplace) and ducts before the heating season. This helps prevent carbon monoxide poisoning.
  • Cleaning the dryer vents
    • When using a clothes dryer, lint accumulates in dryer vents over time, restricting the airflow. This is a fire hazard. The lint buildup can also contribute to excess indoor humidity and dust.
    • A clean dryer vent also allows the dryer to operate more efficiently, using less energy in the long run.

Air duct and vent cleaning should be conducted every 3 to 5 years for a healthier home and business environment. PuroClean can help property owners to achieve that goal. We provide full air duct cleaning services, including sanitization, deodourization and encapsulation of duct systems where needed.
