If you live in or manage a strata property in Vancouver, you may be wondering who is responsible for maintaining the air ducts and ventilation systems—and how important this maintenance really is. The truth is, clean air ducts are essential not only for the health and comfort of residents but also for maintaining property value and HVAC efficiency.
In this post, we’ll break down what you need to know about air duct cleaning for strata units, including who’s responsible, how often it should be done, and why it matters.
Why Air Duct Cleaning Matters in Strata Living
Strata buildings often have shared HVAC systems or individual systems within each unit. In both cases, dust, debris, allergens, and mold can accumulate in the ductwork over time, affecting:
- Indoor air quality for residents
- HVAC performance and efficiency
- Energy bills
- The spread of odors or contaminants between units
A neglected duct system can also contribute to humidity issues, leading to mold growth, or even cause your heating or cooling system to overwork and break down prematurely.
Who is Responsible for Duct Maintenance?
Responsibility for air duct cleaning in strata buildings usually depends on the strata bylaws and whether the ductwork is part of a common or limited common area.
- Common Area Ducts: Typically the responsibility of the strata corporation, especially in systems serving hallways, lobbies, or multiple units.
- Individual Unit Ducts: Often the unit owner’s responsibility, especially if each unit has its own HVAC system or ducts.
It’s important to review your strata bylaws and maintenance schedules to determine who handles what—and to ensure no part of the system is neglected.
How Often Should Ducts Be Cleaned?
While there’s no one-size-fits-all answer, the general recommendation for strata properties is:
- Every 2–4 years for individual unit ductwork
- Annually or bi-annually for common area ventilation systems, especially in high-traffic or high-use buildings
- More frequently if there are pets, smokers, allergy sufferers, or construction/renovation work occurring

Benefits of Regular Strata Air Duct Cleaning
- Improved air quality for all residents
- Better HVAC system performance
- Fewer maintenance issues or unexpected repairs
- Enhanced energy efficiency and reduced utility costs
- Compliance with strata maintenance regulations
