Ducted Air Conditioning FAQ
Thinking about installing ducted air conditioning in your home but not sure if its the right choice for you? We’ve put together a list of some of the most commonly asked questions.
What is Ducted Air Conditioning?
Ducted AC is designed to cool multiple rooms or large, open spaces from an internal unit installed within the roof space of the premises.
A series of ducts run from the unit to each room, allowing you to cool or heat each area using individually. This is known as ’zoning’ and gives you complete control over cooling the entire house.
A typical system consists of:
Outdoor unit positioned outside usually in a utility area
Indoor unit positioned in the ceiling cavity
Interconnecting piping and cabling
Ducting hidden in the ceiling cavity that supplies air to rooms
Ceiling outlet registers and return air grill
Air flow control system, know as a zoning system
How Does Ducted AC Work?
The Ducted unit draws air from the return air grill and conditions the air (changes the temperature and humidity content) at the indoor unit concealed in the ceiling. Once the air has been conditioned it is supplied to the outlet registers at the chosen zones/rooms. This air is continually filtered and recycled.
What Does Zoning Mean?
The term ‘zoning’ refers to the way that ducted systems are split to provide different areas of properties/buildings with specific air solutions. This allows for quite a flexible solution for individual spaces and gives users the ability to create unique airflow solutions based on the specific needs of each room.
Can I Have Ducted Air Conditioning Installed in my Existing Home?
Yes. 75% of our ducted air con installations are in existing homes.
How Long Does Ducted Air Conditioning Installation Take?
For an existing home, most installations can be done in one day, but larger or difficult installations may take a day longer. For a new home or business, the installation is done over two days.
I Have Children With Allergies. Will Ducted Air Con Improve the Air Quality in my Home?
Definitely. The built-in air-purifying filter traps fine airborne particles such as dust and lint and prevents them circulating through your home, resulting in a cleaner and healthier environment for your family.
Australia has one of the highest rates of asthma, seasonal hay fever and other allergies in the world so it’s important to take this into account when choosing the right air con solution for your home…If you or someone in your family suffers from asthma or serious allergies, look for a system with filters that will help to remove allergens from the air and absorb and deactivate bacteria and viruses such as HEPA grade air filters, air purifying filters, mould proof filters or photocatalytic filters. Some systems also include a sterilising function at the end of the filtration process to ensure any nasties that weren’t already removed in the filtration process are eliminated.
I am Replacing an Existing Ducted Air Conditioning system. Can I Reuse The Ducting From the Previous Installation?
As long as the existing ducting work meets the requirements of both the unit and the air conditioned space, and is in good condition, then it is fine to keep the original ducting. Your technician will let you know if this is possible. We don’t recommend re-using existing piping and cabling for new units as different systems have different requirements.
What Size System Will I Need For My Home?
We design every ducted air conditioning system to your specific requirements taking into account a number of factors including:
- How many rooms/square meters that need to be air cooled/heated
- The construction and design of your home
- The number of zones you need
- How many people are living in the home and their lifestyle
A well designed, zoned system usually consists of an 11 to 15 kW ducted system for a small to large medium house. We recommend you talk to one of our consultants who will work with you to plan the perfect system for your home, lifestyle and budget.
Should I Turn My Air Conditioner off During a Storm?
Storms are a part of life in Queensland, and your Ducted Air Conditioning system, like all electrical appliances, is at risk during a thunderstorm. Whilst the risk of a lightning strike is minimal, it can and does happen. An electrical surge can be very serious, causing damage to the internal electrical circuits in your air conditioning, and the controls of your entire system. The repairs from this type of damage can be very expensive, and may result in you needing to replace your whole system. Running your system during heavy rain is ok, as long as you keep the area around your outdoor unit clear of debris and there is sufficient drainage to avoid flooding.
My Uncle is a Plumber/Electrician/Really Good Handyman. Can he do my Ducted Air Con Installation For Me?
No. Government requirements specify that only people appropriately licenced can install the systems. Using an unlicensed operator is not only dangerous and will attract a hefty fine, but can also lead to below par workmanship, damage to your unit, and will void your warranty.
How Much Does Ducted Air Conditioning Cost to Run?
A well-designed system is a lot more economical than you think and a lot more efficient and cost-effective than having multiple split system air conditioners running at the same time
There are a few factors that will affect the running costs of your DUA including;
The type, size and energy efficiency of your system
The electricity tariff you’re paying
How your home is constructed – room size and layout, location and size of windows, insulation
The temperature your system is set to
