Central Coast Exhaust and Ventilation

As noise, pollution and security concerns grow, more and more Australian homeowners are choosing to keep their windows closed. Unfortunately, this not only limits natural ventilation, but also raises the risk of inhaling dangerous pollutants and dust particles. Many are not realising the need for proper Exhaust and Ventilation systems including on the Central Coast.

To enhance energy efficiency, modern homes are carefully insulated and tightly sealed. However, this can lead to inadequate ventilation as they are unable to “breathe.” While opening doors and windows may not always be feasible, it does not effectively facilitate the necessary air movement and exchange required for proper ventilation

Your home in Tuggerah may be damp or mouldy which is typically the result of insufficient ventilation. In newer homes constructed to be airtight, issues with poor ventilation may not be immediately apparent. This can lead to excessive moisture buildup and hidden dampness over time.

Allergens are widespread in our daily life and can cause an allergic reaction.

Common allergens include pollen, mould, animals, dust, etc.

Over the last 15 years, cases of environmental allergies, such as hay fever, eczema, and dust mite allergy, have noticeably increased.

One of the key reasons for the rise in such cases, as shown by research, is the condition of their homes, which are often characterised by damp and cold air.

When we refer to the smell of a stuffy home, we, first of all, mean an unpleasant and sometimes unhealthy smell of cooking, musty clothes and basements, animals, and cleaning agents.

To improve the smell and the quality of the air, it is essential to air a stuffy home, making sure that fresh and clean air frequently fills the room, replacing the stale and possibly contaminant air that causes the smells.

A home ventilation system provides various advantages.

Mechanical ventilation is the controlled movement of outdoor air in and out of a building using fans. This may involve supply fans that push air into the building (positive pressure), exhaust fans that pull air out (negative pressure), or a balanced system that maintains equal airflow without affecting interior pressure.

It is important for home ventilation systems to continuously ventilate the occupied space. There are two types that can achieve this – positive pressure systems or balanced pressure systems. These systems have the ability to filter incoming air and remove harmful pollutants such as dust, pollens, allergens, mould spores, VOCs, smoke, and diesel fumes. However, in certain areas of the home such as bathrooms and laundries, negative pressure systems may be necessary for targeted extraction of moisture. It should be noted that these types of systems can bring in unfiltered outside air with all its potential pollutants.

There are two main types of home ventilation systems: centralised and decentralised. When creating your ideal indoor environment or making changes to your current system, it’s important to consider which type of unit would best suit your needs.

Sub Floor Ventilation

Are you in need of a Sub Floor Ventilation system? It’s important to remember that the area underneath your home requires proper ventilation. Although it may not be an area you frequent, neglecting its air quality can have significant impacts.

 A lack of ventilation can result in musty Odors and sunken floorboards due to moisture, which also contributes to timber decay and mould growth. Additionally, this damp environment provides the perfect breeding ground for termites, and in severe cases, can even lead to health issues.

By addressing any potential dampness or fixing it early on, you can ensure the well-being of yourself and your loved ones. Don’t overlook the importance of having adequate sub floor ventilation as it is crucial in preventing these problems from occurring.

Exhaust fans

To select the best exhaust fan for your area, it is essential to have a good understanding of your specific demands and desires. There is a diverse selection of choices, such as bathroom, kitchen, and light-equipped exhaust fans, allowing you to make an educated choice based on your space’s individual needs.

The bathroom exhaust fan is a critical component of a healthy environment in a sanitary facility. Many specific activities are performed in this room, which often results in dampness. For example moisture is generated through daily activities. The main function of the exhaust fan is to get rid of this moisture. As a result, the bathroom remains dry and hygienic.

Adequate ventilation is crucial for a healthy environment inside the room. The fan will help the airflow and to eliminate stale and polluted air inside the bathroom.

Note ventilation outlets are required such as a door should have a small gap below or a window should be open.

Also outlets to the outside either directly or via ducting are required.

Otherwise, the air will not be circulating, the fan will not be able to function, and moisture as well as volatile organic compounds will be accumulating inside.

Kitchen exhaust fans are a must-have for eliminating cooking smoke, grease particles, and odours from your kitchen. Not only do they enhance air quality, but also keep the space spotless. To optimise their effectiveness, it is recommended to install them directly above stovetops or cooking ranges. When choosing an exhaust fan, look for features such as powerful suction, grease filters, and the ability to adjust fan speed or install without ducts.

For more spacious kitchens or avid cooks, depending solely on range hoods may not suffice in eliminating cooking smoke, grease particles, and odours from the air. This is where kitchen exhaust fans come in handy. These strong ventilation options exceed the capabilities of regular range hoods, ensuring a fresher and cleaner kitchen environment, even when preparing elaborate meals.

Centralised ventilation systems

Centralised ventilation systems are known for their efficient whole house ventilation. These systems use a central unit to supply and extract air from all areas in the home through a series of ducts. Some units can be installed in the roof space outside the thermal envelope, while others require installation inside the thermal envelope on a wall within the home.

The ducts and ventilation grilles are responsible for connecting to your different spaces. It is crucial to keep these ducts in excellent condition to maintain efficient energy consumption in the system. A single leaking duct can significantly impact the overall efficiency of the system. In comparison, centralised units typically offer a wider range of features, better heat recovery, and stronger ventilation capabilities.

The installation of ducting to most rooms in a house can make it challenging to retrofit these systems within the thermal envelope. In contrast, centralised systems intended for high-performance homes that can be installed inside the thermal envelope are typically incorporated during the building process. On the other hand, systems that can be placed outside of the thermal envelope can be easily retrofitted if there is available space in the roof cavity or subfloor for the unit and ducting. When deciding whether whole house centralised ventilation is suitable for your renovation, it’s important to consider the availability of ducting space.

Decentralised ventilation

Instead of having one large central ventilation system, decentralised ventilation utilises smaller units strategically placed throughout a home. For instance some units contain a comprehensive unit with an enthalpy heat exchanger that continuously balances ventilation. Smaller options are typically installed together, with one unit extracting stale air and the other supplying fresh air. These units work in sync for about 30 seconds before switching roles.

A single controller manages this process for convenience and efficiency. Decentralised ventilation is especially useful in compact living spaces such as apartments and can easily be incorporated into renovation projects without the need for extensive ductwork. This makes it an ideal solution for addressing specific issues such as moisture or mold in individual rooms, without major structural modifications – a simple wall installation is all that’s needed to improve the indoor climate.
