Avoid These Common Air Conditioning Mistakes in Lake Macquarie Homes
Air conditioning is an essential part of life for many households across Lake Macquarie, the Central Coast and Hornsby. It provides comfort during the heat of summer and reliable warmth in the cooler months when using a reverse-cycle system. But like any appliance, your air conditioner must be used and maintained correctly to ensure it performs efficiently and lasts for years to come. At Airflow, we specialise in air conditioning repairs across Lake Macquarie and often see the same mistakes made by homeowners. Fortunately, most of these issues are preventable with a little knowledge and regular servicing.
In this blog, we share the most common air conditioning mistakes made in homes across Lake Macquarie and surrounding areas and how to avoid them. Avoiding these missteps will help you save on energy costs, improve system reliability and enjoy year-round comfort.
Running the System with Dirty Filters
One of the most frequent issues we encounter in residential homes is dirty or clogged filters. Over time, dust, pollen and other airborne particles collect on the filters inside your indoor unit. If these are not cleaned or replaced regularly, the system struggles to circulate air efficiently.
This puts extra strain on the fan motor, reduces airflow and increases your energy use. It also affects the quality of air inside your home. In some cases, this can even lead to more serious faults requiring air conditioning repairs in Lake Macquarie.
At Airflow, we recommend checking your filters every one to three months, especially if you use your system frequently or have pets. Regular servicing will ensure filters are cleaned properly and the unit is running efficiently.
Ignoring Routine Servicing
Many homeowners assume that if the system is still blowing cold or warm air, everything must be fine. However, air conditioners need regular professional servicing to identify hidden issues and maintain performance. Neglecting maintenance can lead to reduced efficiency, high energy bills and eventually a system breakdown.
Professional servicing from Airflow includes checking refrigerant levels, inspecting internal components, cleaning coils and testing electrical connections. These steps are essential for preventing expensive faults and keeping your system in top condition.
We provide air conditioning servicing and repairs across the Central Coast and Lake Macquarie, ensuring your unit is ready for peak performance when you need it most.
Setting the Temperature Too Low or Too High
It is tempting to set your air conditioner to the lowest possible temperature during a hot day, but this does not cool the room any faster. Instead, it makes the system work harder and longer, consuming more energy and putting unnecessary strain on its components.
In summer, a comfortable temperature is generally between 23 and 25 degrees Celsius. In winter, setting the system to around 20 degrees Celsius is usually sufficient. These settings balance comfort with energy efficiency and help your system last longer.
By choosing a consistent, moderate temperature, you avoid the risk of overworking the system and needing air conditioning repairs in Lake Macquarie during high-demand months.
Blocking Air Vents or Outdoor Units
Airflow is critical to your system’s performance. If air vents are obstructed by furniture or curtains, or if the outdoor unit is blocked by garden debris, airflow is restricted. This leads to uneven cooling or heating and forces the system to run longer to reach the set temperature.
In Lake Macquarie homes with outdoor units located near shrubs or fences, it is particularly important to maintain clear space around the condenser. We recommend at least 30 to 50 centimetres of clearance on all sides.
During servicing, our technicians inspect both the indoor and outdoor units to ensure air is flowing freely and the system is operating at peak efficiency.
Not Using the System’s Timer or Eco Settings
Many modern air conditioning systems include features such as programmable timers, eco modes and motion sensors. These options help reduce energy use by turning off or adjusting the system when it is not needed.
Failing to take advantage of these features results in higher energy bills and greater wear on the system. Setting your unit to turn off automatically after you fall asleep or before you leave the house is a simple way to reduce operating costs.
At Airflow, we take the time to show our clients how to use these functions as part of our air conditioning installation and servicing across the Central Coast and Lake Macquarie.
DIY Repairs or Installations
Attempting to repair or install an air conditioning system without the proper qualifications is both unsafe and potentially illegal in Australia. Electrical faults, refrigerant handling and incorrect mounting can all cause significant damage or injury.
DIY installations often lead to long-term problems including poor airflow, water leaks and electrical issues. These errors can also void the manufacturer warranty and result in the need for costly air conditioning repairs in Lake Macquarie.
Our team at Airflow is fully licensed and trained to install and repair all major air conditioning brands to industry standards. We provide safe, compliant and high-quality workmanship backed by experience.
Forgetting to Check for Refrigerant Leaks
A slow refrigerant leak can reduce the cooling performance of your air conditioner over time. Signs of a leak include ice forming on the indoor or outdoor coil, hissing sounds or a noticeable drop in cooling output.
Refrigerant leaks can also cause the compressor to overheat and fail, which is one of the most expensive components to replace. If you suspect a leak, it is important to call in a professional as soon as possible.
We offer fast diagnosis and repair of refrigerant issues across the Central Coast and Lake Macquarie, helping you avoid major faults and expensive system failures.
Skipping Seasonal Servicing
Many homeowners use their systems heavily in summer and then switch them off for the cooler months. By the time the next summer arrives, the system may be full of dust or suffering from internal wear.
Booking seasonal servicing ensures your air conditioner is ready to perform when needed. Ideally, you should have your system checked in early spring or late winter to prepare for increased use.
At Airflow, we recommend annual servicing for all residential systems and provide convenient scheduling for clients across Lake Macquarie, Hornsby and the Central Coast.
Not Updating or Replacing Old Systems
Air conditioning systems have a lifespan of around 10 to 15 years, depending on how well they are maintained. Older units are often less efficient, noisier and more expensive to run.
If your system requires frequent repairs or is struggling to cool your home, it may be time to consider a replacement. New systems offer improved energy efficiency, quieter operation and smart controls for better comfort and convenience.
We supply and install modern, energy-efficient systems that suit your home’s layout and usage requirements, providing reliable air conditioning installation across the Central Coast and Lake Macquarie.
