Is it Time to Say Goodbye to Your Air Conditioner? 8 Signs You Need to Update Your Air

Have you been concerned about the performance of your air conditioner lately? If you're unsure about whether it's time to upgrade, there are vital signs you can watch out for. Here are some top reasons to consider before you update your air conditioner.
8 Signs You Need to Update Your Air Conditioner

As the temperature begins to drop, it’s natural to start thinking about your home’s heating. Are you confident it can handle the colder months ahead, or is it time for an upgrade? Keep an eye out for these signs that may indicate your air conditioner needs replacing.


1.  Age of your air conditioner:

The typical lifespan of an air conditioner is around ten years. If your air conditioner is out of warranty, older than ten years and has been causing issues frequently, you may consider replacing it.


2. High energy bills:

Newer air conditioning units are typically more energy-efficient than older ones, which can result in lower energy bills. It could be a contributing factor if your energy bills are high on the days you use your air conditioner. An older or malfunctioning air conditioning unit may consume more energy to cool or warm your home, leading to higher energy bills.

New model Mitsubishi Electric air conditioners can achieve up to 47% energy savings1 when comparing our current model MSZ-AP Series with an equivalent older model from 2002. With the rising cost of electricity, it’s worth considering how you can save energy.


3. Frequent breakdowns and repairs:

If you have to make regular repairs to your air conditioner, it may be a sign that it’s reaching the end of its useful life. Consider the cost of repairs versus the price of a new unit.


4. Your home is never warm or cool enough:

Is your air conditioner struggling to keep your home at the set temperature or blowing warm air in summer and cool air in winter? It could be a sign that your unit is no longer running efficiently.

If it has been a while since your last service by a qualified technician, consider booking one. Servicing your unit regularly can ensure it stays in optimal working condition throughout its life. The technician can also advise on the state of your system and if replacement is recommended.


5. Unpleasant odours and noise:

An unusual smell or noise from your air conditioning unit may indicate a more serious problem. Contacting a qualified service technician for their advice is recommended.


6. Poor indoor air quality:

If you have noticed a decrease in indoor air quality, such as more allergens or dust, it may indicate that your air conditioning unit is struggling to work effectively.

The air conditioner model will determine the type of filters installed. Most air conditioning units typically come with a standard filter and may have optional filter upgrades. Some filter models are washable and have a long lifetime. However, after several years it is worth checking if it is necessary to replace the filters. More information on the filters contained in Mitsubishi Electric split-system air conditioners can be found in the Split Systems Filters flyer.


7. The convenience of new technology:

Newer air conditioning systems have the option of Wi-Fi control. Giving you the ability to control your air conditioner anytime from anywhere you have internet access. No more wondering if you have forgotten to turn the air conditioner off after going out. Or having the convenience of turning on your air conditioner while coming home from work.

Many Mitsubishi Electric split system air conditioners and ducted air conditioning systems have the option of Wi-Fi control2. Your local dealer will be able to assist with more information.


8. Noise levels:

Is it hard to hear the television over the noise of your air conditioner? Updated models contain more advanced technology designed to decrease the noise level of both indoor and outdoor units.

All Mitsubishi Electric wall mounted air conditioners feature “quiet mode”, ensuring super quiet operation, allowing you to sleep, read and relax in peace. You will hardly notice the 18 dBA whisper of the MSZ-AP25 in heating mode when you turn it to quiet mode to enjoy a comfortable indoor environment.


Ultimately, the decision to update your air conditioner will depend on your individual circumstances and needs. It is recommended to consult with a qualified service technician to assess the condition of your current unit and determine whether an update is necessary.
