How Do I Ensure Proper Ventilation with a Split System?

In every Australian home, having an effective and efficient air conditioning system has become pivotal, especially considering the country's increasingly hot summers. Among the plethora of options, split-system air conditioners have emerged as an increasingly popular choice.

This blog provides an in-depth understanding of split system air conditioners, addresses key concerns, and guides you towards maximising proper ventilation. We will also consider power consumption issues, cost implications, and how to choose the best model for your needs.

Defining Split System Air Conditioners

Amid the summer heat in Australia, an air conditioner isn’t just a luxury – it’s a necessity. One of the most popular choices among Aussies is the split-system air conditioner.

But what exactly is a split system? Simply put, the split system is a type of air conditioner with two parts: an indoor unit and an outdoor unit.

The indoor unit, often wall-mounted, extracts the hot air inside the house by absorbing its heat into a refrigerant. The hot refrigerant is then sent to the outdoor unit to dissipate the heat.

In the cooling process, the indoor unit also filters the air, improving the indoor air quality. Contrary to its name, the split system air conditioner not only cools your home in summer but also can produce heat during winter. Its versatility can keep your house comfortable all year round.

Different models of split-system air conditioners have varying capacities, suitable for heating or cooling smaller single rooms or larger open-plan areas. They can be installed close to the floor or onto the wall, depending on the particular home setup and owner’s preference.

Efficiency of Split Systems

A usually asked question is whether split systems are energy efficient. With advances in technology, many new models of split-system air conditioners are designed with energy efficiency in mind. Brands like Mitsubishi Electric and Mitsubishi Heavy Industries have focused heavily on creating systems with low power consumption.

To further answer the question “Do split systems use a lot of electricity?”, check the zoned energy rating label provided on each system. In Australia, the more stars shown on the label, the lower the running costs and the more energy-efficient the model is.

Choosing a more efficient split system air conditioner not only allows you to save on electricity bills but also reduces the environmental impact. Energy-efficient models, combined with correct installation, operation, and maintenance, can provide effective and efficient heating and cooling for your home.

Split vs Ducted Systems

So, which is better – split or ducted air conditioning? Both have their benefits and limitations. Therefore, the decision will generally depend on factors such as the size of your house, the room layout, and your budget.

The main advantage of the split system is flexibility. They can be installed in specific rooms based on your needs, and each unit can be individually controlled. This is better for smaller houses or for most homes where certain rooms are often unused.

On the other hand, ducted systems are usually installed in houses during the construction phase. They are typically more expensive than split systems but deliver air throughout the home via ducts in the ceiling or floor. This can be more aesthetically pleasing due to the hidden air conditioning units.

Running Costs and Power Consumption

Another common question is how much it costs to run a split-system air conditioner. This can vary per model, frequency of use, temperature settings, house insulation, and current power prices in Australia.

To reduce running costs, do not run frequent short cycles in your split system as it uses more energy. Also, regularly clean and replace the filters for peak performance.

Keep your windows and doors closed when the conditioner is running, and use the system’s wi-fi-enabled remote control to maximise its operation.

Choosing the Right Split System

With so many models and brands available in the market, how do you choose the right split-system air conditioner? You might compare models for factors like cooling and heating power, energy efficiency, noise levels, and smart features like Wi-Fi control.

Trusted brands such as Mitsubishi Electric and Daikin offer a range of split-system air conditioners with excellent performance and energy-efficient features.

The best prices can often be found during end-of-season sales. Doing your research, comparing different brands and models can help you find a split system that fits your needs and budget.

Proper Ventilation with a Split System

A split-system air conditioner can contribute to good indoor air quality by circulating and filtering the air. To maximise these benefits, you want to operate your split system correctly. Here are a few steps to secure proper ventilation with your split-system air conditioner:

  • Set optimal temperatures: Avoid setting the temperature too low in summer or too high in winter. Maintain a consistent room temperature of around 24ºC in summer and 19ºC in winter. This allows for better air circulation and prevents overworking the system.
  • Clean or replace filters regularly: Most split-system models have filters that need regular maintenance. Check the manufacturer’s recommendations for specific time frames and follow them diligently. A clean filter helps improve air quality and prolongs your split system’s life.
  • Consider indoor unit placement: The indoor unit should be installed where it can circulate air most effectively. Ideal locations include a central open-plan area for a whole-house system or the area of a room where you spend the most time if it’s a single-room system.
  • Proper outdoor unit installation: Make sure the outdoor unit is installed correctly and sufficiently far from walls or other obstructions, allowing proper airflow and heat exchange. This contributes to effective ventilation and efficient system operations.
  • Integrate with natural ventilation: Whenever possible, open windows or doors to facilitate natural ventilation and air exchange. This can help maintain healthy air quality and reduce the reliance on your split system as the sole source of ventilation.
  • Regularly maintain your split system: As mentioned earlier, working with a heating, ventilation and air conditioning (HVAC) professional for regular maintenance will guarantee your system operates at peak performance. This will increase efficiency and help maintain optimal air quality in your home.

Engaging an HVAC Professional

For the installation, maintenance, and troubleshooting, working with a qualified HVAC professional is key. The benefits of working with an HVAC professional greatly outweigh the temptation to perform a DIY installation or maintenance.

Firstly, HVAC professionals fully understand how split system air conditioners work, and they’re well equipped to install indoor and outdoor units correctly and safely.

Secondly, regular maintenance conducted by a qualified technician will extend the system’s life and make sure it operates at peak efficiency. This equates to saving on energy costs in the long term.

Lastly, in case of technical issues that may arise, trained HVAC professionals will diagnose these problems accurately. They will have ready access to the required tools, spare parts, and have the necessary skills to carry out the repairs safely.

Versatile and Practical Climate Control

A split-system air conditioner is a versatile and practical choice for most Aussie homes. It provides adequate cooling in the scorching summer and warm heating for the chilly winter days.

Armed with knowledge, you can now confidently explore a multitude of brands, models, and options, choosing the split system air conditioner that best fits your needs. With proper care and maintenance, you can enjoy comfortable, energy-efficient air conditioning and optimal air quality throughout the year.
