A ducted air conditioner is essential for maintaining a comfortable home environment, especially during extreme weather conditions. However, like any appliance, regular and timely maintenance is required for it to function efficiently.
Knowing the signs that your ducted AC needs servicing can prevent costly repairs and ensure the system continues to operate effectively. This article outlines the key indicators your ducted air conditioner might need attention.
Unusual Noises: A Clear Indicator
Clanging, Whistling, or Banging Sounds
If your ducted air conditioning system is producing unusual noises, this is often a sign that something is wrong. Clanging, banging, or whistling sounds can indicate issues with internal components. For example, loose parts, damaged fans, or debris trapped in the ducts can cause these noises.
Grinding or Screeching Noises
Grinding or screeching noises can signal a more serious problem, such as a malfunctioning motor or worn-out bearings. If the issue lies in the motor, immediate servicing is necessary to prevent a complete breakdown of the unit. These sounds should never be ignored, as they can result in costly repairs if left unattended.
Reduced Airflow and Uneven Cooling
Weak Airflow
One of the most common signs that your ducted AC requires maintenance is reduced airflow. If the air coming from your vents feels weak, this could indicate a clogged filter, a blocked duct, or even a failing compressor. Over time, dirt and dust accumulate in the system, obstructing the airflow and reducing efficiency.
Uneven Cooling Throughout the House
If some rooms in your home feel colder or warmer than others, your ducted air conditioning system may be struggling. This uneven cooling can be due to various factors, including blocked vents, leaking ducts, or an issue with the thermostat. Poor airflow can reduce comfort and increase energy bills as the system works harder to regulate temperatures.
Strange Odours: A Warning Sign
Musty Smells
A musty or damp smell from your ducted air conditioner can indicate mould or mildew growth inside the system. Mould is a common issue in units that haven’t been cleaned or serviced regularly. Mould not only affects the air conditioner’s performance but can also pose a health risk to occupants, particularly those with allergies or respiratory conditions.
Burning Smell
This could indicate an electrical problem or overheating components, such as the wiring or motor. Electrical issues can be hazardous, so it’s essential to turn off the system and call for a professional maintenance service right away. Addressing the issue quickly can prevent more severe damage or safety hazards.
Increased Energy Bills: A Hidden Sign
Unexpected Spikes in Electricity Usage
If you’ve noticed a sudden spike in your energy bills, it could be a sign that your ducted air conditioner is not operating efficiently. When the system struggles to cool your home, it consumes more energy. Common culprits include dirty filters, blocked ducts, or a failing compressor, all of which force the unit to work harder than necessary.
Older Systems and Reduced Efficiency
As air conditioners age, their efficiency naturally decreases. If your system is over 10 years old and you notice rising energy bills, it may be time to consider a maintenance service or a replacement. An older system that requires frequent repairs may no longer be cost-effective, and upgrading to a more energy-efficient model could provide long-term savings.
A well-maintained ducted air conditioning system ensures comfort and efficiency in your home. However, it is crucial to recognise the signs that your system requires maintenance. By addressing these issues promptly, homeowners can extend the life of their system and enjoy consistent, reliable cooling throughout the year. Regular servicing by a qualified migration agent in Australia is essential to keep your ducted AC in peak condition.
