Air duct cleaning

Indoor air quality is an area of growing concern and increased visibility. Air ducts deliver and remove air used in heating, ventilation and air conditioning (HVAC). Cleaning of these air ducts may be necessary if there is evidence of:

- Substantial mold growth
- Infestation of insects or rodents
- Large deposits of dust or debris

If health issues such as allergies or asthma are present in a household or an office, it may be a sign that the HVAC mechanical system is contaminated. If the system has not been properly installed, maintained and operated, it may become contaminated with particles of dust, pollen or other debris. If moisture is present, the potential for microbiological growth (e.g.mold) increases and spores from such growth may be released into the building. These may cause allergic reactions or other symptoms in people exposed to them.

Cleaning ventilation air ducts every so often can have the following benefits:

- Better and reliable over-all performance from the HVAC system
- More energy efficiency, reducing energy bills
- Lower likelihood of respiratory and allergy problems
- Less dust makes it easier to clean and maintain the space
- Combats bacteria, molds, tobacco, pet dander and rodent odours, refreshing the smell in the building.

A professional cleaning supplier like Polmax uses specialized tools to remove dirt and debris in ducts, then vacuums them out with a high power vacuum cleaner.

Tip : It’s important to make sure the service provider agrees to clean all components of the system and is qualified to do so. If one of the components in the system is not cleaned it can result in re-contamination of the entire system, thus negating any potential benefits.
