FAQs
Why is proper ventilation so important for homes and businesses in Cowan?
Cowan’s bushland setting means there is a high level of pollen, dust, and wildfire smoke during parts of the year. Without a balanced ventilation system, these contaminants accumulate indoors, causing respiratory irritation and stale, humid air. Modern mechanical ventilation brings in filtered outside air while exhausting stale air, dilutes pollutants, helps control humidity, and supports the efficiency and lifespan of your heating and air-conditioning equipment.
What type of mechanical ventilation system should I install—HRV, ERV, or a fresh-air fan—and how do they differ?
A Heat-Recovery Ventilator (HRV) captures heat from outgoing air and transfers it to the incoming fresh air, making it ideal for colder winter nights in Cowan. An Energy-Recovery Ventilator (ERV) exchanges both heat and some moisture, helping control indoor humidity during Cowan’s warmer, muggy summer days. Simpler fresh-air fans provide outside air but do not reclaim energy, so they are cheaper upfront but cost more to run. We recommend an HRV for well-insulated homes focused on winter efficiency, an ERV for balanced year-round comfort, and fresh-air fans only where budgets are tight or space is limited.
How often should I service or clean my ventilation and ducted air-conditioning system?
Filters on HRVs, ERVs, and return-air grilles should be inspected monthly and cleaned or replaced every 3 months. Supply and return ducts generally need professional cleaning every 3–5 years in Cowan’s dusty environment, or sooner if you’ve renovated, notice visible mould, or suffer unexplained allergy flare-ups. Fans, heat-exchange cores, and condensate drains should receive an annual tune-up by a licensed HVAC technician to keep airflow rates and energy recovery at peak levels.
What steps can I take to improve indoor air quality if someone in my household has asthma or allergies?
Start with a sealed duct system and high-MERV (or HEPA) filtration on both the ventilation unit and the central air handler. Run the ventilation system continuously on a low setting to ensure a steady supply of filtered outdoor air. Maintain 40–50 % indoor humidity with an ERV or stand-alone dehumidifier, because dust mites and mould thrive above 60 %. Choose low-VOC paints, furnishings, and cleaning products, and schedule a professional IAQ assessment every two years to test for particulates, formaldehyde, and carbon dioxide levels.
How can I tell if my existing ducts or ventilation equipment need upgrading?
Warning signs include rooms that always feel stuffy or hard to heat/cool, whistling or banging noises in ductwork, visible mould on registers, excessive dust on surfaces, or energy bills that keep climbing despite thermostat settings. A blower-door test can reveal hidden leaks, while an airflow and static-pressure check identifies undersized or damaged ducts. If your equipment is over 15 years old, replacing it with a modern, energy-recovery system can cut ventilation-related operating costs by up to 40 % and noticeably improve comfort.
Are there any rebates or incentives in New South Wales for upgrading my ventilation or HVAC system?
Yes. Under the NSW Energy Savings Scheme (ESS), high-efficiency heat-recovering ventilation units, variable-speed air-conditioning compressors, and smart thermostats may qualify for Energy Saving Certificates (ESCs), which lower upfront costs. Additional rebates are sometimes offered by Ausgrid and local councils for homes that install energy-recovery ventilation or upgrade to heat-pump heating and cooling. We can prepare the paperwork and connect you with accredited certificate providers to maximise your savings when you install a new system in Cowan.
