Even the best brand of air conditioning units has a limited lifespan. For the average, a well-maintained AC is said to last around 10 to 12 years. As your unit slowly comes to its peak age, problems are expected to be encountered.

Let us show you the signs that say the right time to replace your AC unit has come. Read on.


When Should You Replace Your AC Unit?


When to replace your air conditioner?

Here are the signs that will tell you about the right time to replace your AC.


You can hear strange noises

Do you hear these strange noises from your AC?

  • Grating
  • Rattling
  • Grinding
  • Squealing
  • Screeching

A properly functioning AC, especially the new upgraded types, operate silently. So, If you’re familiar with your AC and you suddenly hear these strange noises, then it’s time to have it checked. These sounds may be because of a loose part inside or a clogged mechanism.

If you here any of these sounds, it will be best to call for an expert AC technician to visit and check your unit. They can help you assess it and tell if it’s still repairable or you’ll need to buy a new one.

This same goes to foul odours that may be emitted by your aircon. Bad odours can be a nuisance and a sign that there’s a serious problem with your unit. It could mean your coil inside the unit is blocked, damaged pipework, gas leaks or mouldy ductwork, which can eventually lead to a unit replacement.

So, make sure to take note of the sounds and smell coming from your AC. These can tell you if there’s a problem with it and you need to act right away.


It’s experiencing short cycling

The on and off-cycle observed by your aircon is normal. This helps the unit in maintaining the set temperature to reach. However, if your unit is switching off itself randomly or it is taking too long to start, then most likely it’s experiencing short cycling. It means that your unit is malfunctioning.

This process of short cycling can stress out your AC. As a result, this can cause it to fail, especially if it is not fixed immediately. It can also increase your power bill. If it’s just a blown fuse problem, then you’re still lucky, but if not, then it’s time to replace your AC.


Repairs are becoming frequent

Does it seem like your AC technician is becoming a regular visitor at your doorstep? Then this means that the repairs for your AC are becoming frequent as well. Which also means frequent expense from your savings, right!

Typically, repairs and services shouldn’t bother you that much because AC manufacturers provide 5-year warranty for their services. If you’re getting 10, then that’s better for you. But if your unit is experiencing frequent repairs, especially outside the warranty period, then it’s time to get a new air conditioning unit.

By replacing your unit, you can get to enjoy both a new AC and a new services warranty at the same time. Which, by the way, can allow you to save on your savings rather than spending it on frequent repair services.

Your bills are increasing

The next sign that will tell you it’s the perfect time to replace your aircon is your increasing bill. If you haven’t added any new appliances but your energy consumption is increasing, especially when you’re using the air conditioning system, then most likely your unit is the culprit.

If your AC may look fine but your bills are dramatically increasing, then you may want to do an energy audit. It will help you check whether your aircon or not is the cause of the surge in your bill.

If it all goes down to your AC, it’s your sign that there’s a problem with your unit and it might be replacement time. You can also try to call for an aircon technician to clean your unit and see if it changes anything. But if it doesn’t do the trick, perhaps your unit might be reaching the end of its working days.

To help you make sure that your unit needs to be replaced, call for an expert AC technician to check your unit first.


It’s not cooling or heating your home properly

Is your AC unit not cooling or heating your home properly anymore? Even after having it serviced, cleaned, and maintained yet the airflow seems to be diminished?

Perhaps, your unit’s compressor is already on its last days or your system is running out of gas. This is another sign that will tell you that it’s time to get a new AC. Just make sure that you’ve checked filters or called for professional help to service your unit first.



These are just some of the evident signs that your unit is on its last days.  To keep your home comfortable in every season, it’s important to ensure that necessary maintenance and repair is applied. Otherwise, it might be the perfect time to invest in a new unit with a warranty.
