Whole Home Ventilation

Whole home ventilation ensures your entire house enjoys constant dry airflow year-round, reducing unwelcome dampness, mould, condensation, and stale air.

A well-ventilated home is a home that minimises stale air, mould, and condensation.

Unfortunately, Wellington is afflicted with many mouldy homes, with as many as 12,700 houses that are sometimes or always mouldy – that’s almost one in five houses in the capital, according to recent Census data.

Aside from the unpleasantness of living in a damp home that smells of mould, this issue can be a health risk, especially for those dealing with allergies or asthma. Those with allergies may have reactions such as shortness of breath, whereas asthmatics who are allergic can experience asthma attacks.

Even for those who are not allergic or otherwise at risk, mould can cause health issues such as irritation to the eyes, skin, throat, and nose.

How can you prevent mould, stale air, and condensation?

Opening windows and doors on fine days to allow for a natural airflow is a great way to air out a home and reduce dampness and stale air. However, the weather won’t always be warm or dry enough to lend a hand.

Fortunately, full-home mechanical ventilation can minimise the occurrence of mould, stale air, and condensation. From the bathroom to the living room to the bedrooms, ventilation throughout the house will keep the air moving, and even extract moisture from the air.

For rental properties, the Healthy Homes standards require all bathrooms and kitchens to have mechanical extract ventilation (in addition to opening windows in habitable rooms), so property owners may choose to install whole home ventilation to ensure a healthy environment for tenants throughout the house, and to protect their investments long-term.

Installing whole home ventilation

MC Electrical has the skills, experience, and knowledge to install ventilation systems throughout the home for a drier, healthier, and happier living environment. There are two systems you can consider for your home; positive pressure systems and balance pressure systems.

Positive pressure systems take the dry air from your roof cavity, filter it, and distribute it throughout the home through vents and ducting. This dry, warm, filtered air moves through the home to push out stale air, and is ideal for older homes that breathe naturally.

Balanced pressure systems are suited for newer, air-tight homes. This mechanical system introduces fresh air from the outdoors to circulate through the home, while also extracting old air out an exhaust vent. These systems are also beneficial as they can be upgraded for improved efficiency, recycling heat energy and tempering incoming cool air.
