What is an air handler in a ducted air conditioning system?

An air handler is a key component of a ducted air conditioning system that circulates and regulates air throughout your home. It houses essential parts like the blower, heating and cooling elements, and filters.

How do I know if I need to upgrade my air handler?

Signs that you may need to upgrade include inconsistent temperatures, increased energy bills, unusual noises, or frequent repairs. If your air handler is older than 15 years, it may also be worth considering an upgrade.

What key features should I look for when upgrading my air handler?

When choosing a new air handler, consider features such as energy efficiency ratings (SEER or EER), variable-speed blowers for better air flow control, noise levels, and compatibility with existing ductwork.

How can I maintain my air handler to ensure its longevity?

Regular maintenance includes changing or cleaning air filters every 1-3 months, scheduling annual professional inspections, and keeping the area around the air handler clear of debris to promote adequate airflow.

What is the average cost of upgrading an air handler in Australia?

The cost can vary widely depending on the model, features, and installation requirements. On average, you might expect to pay between $1,500 to $4,500 for an air handler replacement, including installation.

Strategies for Minimising Duct Noise

Energy Efficiency and Duct Sizing

e velocity pressure. Total pressure is the sum of static pressure and dynamic pressure caused by the air movement. Assessing the pressure loss across various system components helps identify potential problem areas. Regular monitoring ensures that airflow remains within the desired ranges, which is particularly important in variable air volume systems that rely on precise control for energy efficiency and comfort.
Noise Control in VAV Systems
Noise generated by airflow in ducted air conditioning systems can lead to discomfort in occupied spaces. Proper duct sizing and layout play pivotal roles in controlling these noise levels. The selection of duct material also significantly influences noise transmission. Smooth, insulated duct surfaces reduce turbulence. This helps in minimising sound levels while ensuring efficient airflow.
A careful assessment of fan speeds and airflow paths is necessary for effective noise control. Reducing the speed of fans might decrease noise but can also impact the system's efficiency. Other design strategies include the installation of acoustic liners or sound attenuators, which absorb and dissipate sound energy. Implementing bends and offsets in duct design also aids in diffusing noise. Additionally, strategic placement of VAV boxes can further mitigate sound transmission into occupied areas.
Strategies for Minimising Duct Noise
Effective noise control is crucial in maintaining a comfortable indoor environment when using VAV ducted air conditioning systems. One common strategy involves the use of acoustical duct liners, which can absorb sound and buffer vibrations within the ductwork. These liners are typically made from sound-absorbing materials and can significantly reduce airborne noise produced by the system.

Another approach focuses on the careful design and layout of the duct system. Avoiding sharp bends and using gradual transitions can help minimise turbulence and airflow resistance, which in turn reduces noise levels. Additionally, maintaining appropriate sizes for the ducts ensures that air velocity remains within desirable limits, thus further limiting potential noise issues. Implementing these strategies contributes to a quieter operation of air conditioning systems while enhancing overall occupant comfort.
