To check for air flow in a residential or commercial HVAC system, start by feeling for air coming from supply vents in each room. A significant temperature difference or weak airflow indicates a potential problem. Use an anemometer to measure the actual velocity in feet per minute (FPM) at the registers. Compare readings across the house; inconsistent flow often points to ductwork issues like leaks, blockages, or improper sizing. Ensure all vents are open and unobstructed by furniture or drapes. Inspect the air filter—a dirty filter is a common culprit for reduced airflow. For a comprehensive diagnostic procedure, including checking static pressure and duct integrity, refer to our detailed guide, Air-Flow Check.
While Melbourne generally enjoys good air quality compared to many global cities, it is not immune to air pollution. Key concerns include seasonal spikes from bushfire smoke, which can significantly elevate particulate matter (PM2.5) levels, and wintertime wood heater smoke in some suburbs. Traffic emissions also contribute to nitrogen dioxide levels in urban corridors. For residents, especially those with respiratory conditions, these periodic events can pose health risks. Maintaining impeccable indoor air quality becomes crucial during such external pollution events. Effective HVAC maintenance, including regular duct cleaning and using high-grade filters, is a professional standard to protect indoor environments, a principle detailed in our internal article Because The Air You Breathe Should Be Impeccable..
