14 Tips for Extending the Life of Your Air Conditioner

November 29th, 2022
Extending The Life Of Your Air Conditioner

The average air conditioner lasts between 10 and 12 years before it needs replacing, but that doesn’t mean you can’t extend the life of your system.

There are many steps you can take to extend the lifespan of your air conditioner, but as with everything, how long your system lasts will depend on how well you treat your unit.

A well-cared-for air conditioner will work efficiently, save you money, and last for many years. A poorly-cared-for air conditioner will consume more energy, cost more money, break down more regularly, and ultimately need replacing before its time.

Whether you have LG split system air conditioners or a Brivis ducted heater with add-on refrigerated cooling, we can help you take care of your AC.

Here are 14 simple ways you can extend the life of your air conditioner according to our Melbourne air conditioning team.

1. Make Sure Your AC Is Properly Installed

If you haven’t installed your new AC yet and you want to maximise its lifespan, make sure you take the following steps:

    • Ensure indoor and outdoor units are placed in the correct location
    • If you’re installing a ducted air conditioner, partner with an expert in ductwork design
    • Ensure your air conditioner is not oversized or undersized, as this will cause it to work harder from the very beginning!
    • Choose a professional who uses quality materials, including pipework, ductwork, and drainage materials
    • To ensure all these steps are followed and your system is expertly installed, choose a licenced, qualified, and insured team to install your air conditioner

    2. Set the Right Temperature to Reduce the Burden on Your System

    Every time you set your thermostat, you have a choice.

    You can set the temperature excessively high or low, which increases running costs and accelerates wear and tear.

    Or you can set the temperature closer to the outdoor temperature, which will provide effective heating and cooling that is affordable and easier on your system.

    In winter, we recommend setting your system between 18°C and 20°C, and in summer, we recommend setting your system between 25°C and 27°C. 

    These temperature ranges will help your air conditioning unit last longer while reducing your electricity bills.

    3. Turn Off Your Air Conditioner from Time to Time

    Even if you take good care of your air conditioner, excessive use will cause the end of its life to arrive faster.

    If you’re not at home or you’re going into another room for a couple of hours, turn off your air conditioner. If you’re going away for a few days, make sure your system isn’t programmed to turn on automatically.

    So, when it comes to your air conditioner just remember: If you overuse it you will lose it, so turn it off like a light switch.

    4. Clean and Change Your Dirty Air Filters

    Cleaning and changing dirty air filters is one of the most important things you can do to take proper care of your system and increase its life expectancy. Excess dust can affect your air conditioning sensors and obstruct other internal parts, which eventually leads to malfunction.

    We recommend removing, washing, drying and reinserting air filters regularly, generally every one to three months. You should also replace filters that are damaged or excessively dirty. It’s usually easy enough to clean and replace filters yourself if you have a split system. Refer to your user manual to get started. 

    You might find that your system has multiple different filters, such as titanium apatite photocatalytic filters. Some filters need checking more or less often than others, so keep an eye on this when reading your manual.

    As well as scheduled filter cleaning and replacement, you should give filters a clean after activities like dusting the home, moving around furniture, or renovations, as these activities will generate dust that can end up in your air conditioner.

    5. Clean Other Parts of Your Air Conditioner Regularly

    As well as cleaning your filters, there are other parts of your AC that you can clean yourself to extend its life. You can wipe the louvres and the front panel of a split system’s indoor unit with a dry or damp cloth. You may also be able to remove the front panel to clean the underside of this panel. Refer to your owner’s manual for more information on removing the front panel. You can also wipe down the exterior of the indoor unit and outdoor unit with a soft cloth. 

    Taking the time to wipe dust and dirt off these areas regularly will prevent the dust from travelling further into your system and help to extend the life of your air conditioner.

    6. Take Care of the Area Around Your Outdoor Unit

    Whether you have a ducted air conditioner or a split system, your AC will have an outdoor unit. As well as removing dust and dirt from the exterior of your outdoor unit, you should also ensure that the space around the unit is clear and open.

    If leaves, trees, and shrubs have started invading the space, make sure you cut them back and clean them up. Also, make sure there isn’t any loose concrete or other debris that could blow into the system. 

    If your outdoor unit is obstructed by greenery or debris, this could cause a major malfunction that wipes years off your system’s life. So, make sure you take care of that critical outdoor area, especially after periods of rain and strong winds.

    7. Make Sure There Are No Airflow Problems

    Every few weeks, take a moment to make sure furniture isn’t sitting on top of ducts and bookshelves haven’t been moved in the way of indoor air conditioning units. These obstacles will limit your airflow and cause your system to work harder to cool your room – which leads to increased wear and tear.

    You might not think anything is disrupting your air conditioner, but over time, furniture gets shifted, items get dropped, and new pieces are haphazardly placed.

    Moving these obstructions is an easy fix that will result in more effective heating and cooling, reduced wear and tear and cheaper utility bills!

    8. Take Advantage of the Different Modes on Your Air Conditioner

    Using the different modes on your air conditioner not only results in more affordable and effective heating and cooling but also a longer-lasting air conditioner.

    Here are a few tips.

    • Auto mode is a convenient way to regulate room temperature, but it can cause your system to regularly switch between heating and cooling, which gives your air conditioner a workout. Instead, consider using the Heat mode for heating and the Cool mode for cooling.

    • If your main priority is reducing humidity rather than reducing the temperature, try your air conditioner’s Dry mode. This mode is generally less energy intensive, which reduces the demand on your system.

    • Night mode or Sleep mode is designed especially for when you’re in bed. If you want the AC on while you sleep, try this mode. It gradually alters the temperature to help you sleep comfortably, sometimes changing the temperature by as little as half a degree at a time. This will be less demanding on your system than trying to maintain a set temperature as the weather gets cooler throughout the night.

    • If you just want a natural flow of fresh air and you’re not bothered by the current temperature, save your AC the strain and use its Fan mode instead. This mode won’t have to work hard to change the temperature as it merely circulates fresh air around the room, much like a ceiling fan.

    • Finally, many systems have an Eco mode or Econo mode, and this one speaks for itself. With a focus on energy savings, this mode is easier on your wallet, easier on the environment, and easier on your air conditioning system!

    9. Use Fan Speeds Wisely

    As well as the modes mentioned above, you can also alter fan speed.

    Generally speaking, a higher fan speed is more demanding while a lower fan speed is easier on your system. 

    However, using a higher fan speed for a few minutes when you first turn on the system can help you reach a comfortable temperature sooner. Then your air conditioner merely needs to maintain that temperature, which is less demanding. At this point, you can switch to a lower fan speed. Remember to alter the fan speed but not the temperature when using this method.

    So, in summary, low fan speeds are useful for temperature maintenance (e.g. overnight or when you have already reached the target temperature) and when you want to reduce humidity. 

    Higher fan speeds should be used sparingly but can assist in reducing wear and tear by making you comfortable sooner, thus allowing your AC to quickly switch into a low-demand temperature maintenance mode.

    10. Make the Most of Technology

    Technology can make your life easier and it can also make your air conditioner’s life easier.

    Smart thermostats and timers can ensure your AC turns off when not in use, even when you forget to switch it off.

    Wi-Fi controls allow you to remotely turn your air conditioning on or off using your smartphone. This means you can gradually pre-heat or pre-cool your home rather than blasting your system and wearing out its parts when you arrive to a hot home.

    Of course, being able to turn your system off from anywhere is always useful. It allows you to double-check that you (or your kids) haven’t forgotten to switch the AC off when nobody is using it.

    Modern air conditioners like LG split systems are also equipped with other smart technology features that make it easier to monitor and adjust energy levels. This results in improved efficiency, less power consumption, and an AC that can last for years and years!

    11. Use Other Household Appliances and Features to Assist

    You can use other parts of your home to make your AC’s life easier and increase its overall lifespan. Here are a few tips:

    • Check your ceiling insulation and install new insulation if required. This will help you to maintain the target temperature without overworking your air conditioner.

    • Close your curtains and blinds in hot weather to keep out the sun and give your air conditioner less work to do. On cold days, keep your curtains and blinds open during the day to let the natural warmth of the sun into the home. If you want to turn the heater on, simply close the curtains and blinds again – this will make it harder for the heat to escape and give your AC less work to do.

    • Using ceiling fans alongside your air conditioner allows you to circulate air throughout the room faster, meaning your AC doesn’t need to work as hard.

    • If you use a clothes dryer, try switching it on at night when it’s cooler outdoors. Clothes dryers will generate a bit of extra heat that makes things easier for your AC.

    • In warmer weather, make sure any unused electrical appliances are switched off. This will prevent excessive heat from being generated and give your air conditioning less warmth to fight against.

    • On a similar note, make sure heat-generating appliances aren’t kept too close to wall-mounted controls or indoor air conditioning units, as this can affect the temperature reading and cause your system to work harder.

    12. Keep an Eye (and an ear) On Your Air Conditioning System 

    Apart from a bit of cleaning, the tips above don’t really delve into DIY air conditioning care. That’s because servicing or repairing your own AC can be more hassle than it is worth.

    However, one DIY task you can do to extend the life of your air conditioner is a visual inspection. Some things to look for include:

    • Water or refrigerant leaks, including dripping water
    • Dust or smoke blowing from indoor or outdoor units during operation
    • New or excessive movement of the indoor or outdoor unit during operation
    • Exposed electrical parts
    • Cracks in the unit
    • Stones and debris lodged in the outdoor unit


    You can also keep an ear out for problems, including:

    • Increasingly loud whistling, humming or squealing
    • Banging, buzzing, or rattling noises
    • Any other strange sounds or abnormal noises

    If you see or hear anything out of the ordinary, DO NOT investigate further by trying to pry open the unit with your fingers, a screwdriver or any other tool. This could be dangerous and may ultimately jeopardise the condition of your air conditioning system.

    If you notice something, call a professional heating and cooling technician. Addressing these issues as soon as you notice them will give you the best chance of fixing the issue fast and ultimately extending the life of your system.

    This brings us to our next point… 

    13. Don’t Hesitate to Schedule Air Conditioner Repairs

    It’s unwise to use your air conditioner if you’re worried that something is wrong with it. In the best-case scenario, your air conditioner just won’t work as well. But in the worst-case scenario, using your AC could be dangerous and it will result in permanent damage that wipes years off your system’s life.

    That’s why you should arrange air conditioner repairs as soon as you notice a problem. Partner with a fully trained, highly qualified, and comprehensively insured heating and cooling technician to fix the immediate problem fast and extend the life of your system in the long term. Not all air conditioning issues require emergency repairs, but even the most basic AC problem should be seen to as soon as possible to avoid costly repair bills.
