Clear air, happy days.

Home Ventilation: Control window condensation, improve air quality.

Home ventilation is essential to control condensation, purify indoor air and create a drier healthier home that's more energy efficient to heat.
Moisture is created in a home just from everyday living: showers, cooking, laundry and simply breathing. Excess moisture trapped in the home will cause dampness to the air and contents causing crying windows and ideal conditions for mould and mildew growth.

What types of ventilation systems are there?

  • Negative pressure systems - are extractors typically used to remove moist or stale air from a room such as a bathroom, laundry, kitchen, or hot air from a roof space.
  • Positive pressure systems - are systems used in older homes (pre-2000) and are designed to duct fresh, dry, filtered air into the home that pushes out stale, moist air though gaps around doors and windows.
  • Balanced (neutral) pressure systems - are an advanced ventilation system reflecting the airtight nature of modern homes. The system balances the pressure of gently blowing fresh, filtered air into the home while mechanically extracting the same amount of stale, moist air.
  • Heat Recovery Ventilation (HRV) & Energy Recovery Ventilation systems (ERV) - these balanced ventilation systems ensure the heat from your heat pump or other heat source is not lost with the introduction of fresh air.

3 steps to address a damp home:

  1. Limit moisture at it's source via bathroom and kitchen extractors, lids on pots, drying clothes outside or in an externally vented clothes dryer, keeping ensuite doors closed.
  2. Air out your house. Open doors and windows for 10-20 minutes per day. Aim to create a cross breeze to quickly flush damp air out of the house.
  3. If dampness remains, invest in a ventilation system to protect your health and home from the harm associated with mould and mildew.
