Keep reading to learn our top ten warning signs it’s time to invest in a new cooling system for your home.

1. There are Temperature Differences in Your Home

A well-functioning air conditioning system must keep temperatures regulated in all rooms in your house. Therefore, if you feel hot when in your dining room and cold when in the living room, your cooling system is wanting.

Temperature variations in different rooms may be due to clogged or damaged air ducts. The unit may also be too small to deliver adequate conditioned air in the rooms.

Replacing it with a new one will ensure a reliable supply of conditioned air in all the rooms.

2. You Have to Shout to Be Heard

Do you need to raise your voice for you to be heard while in your home? Of course not! If you find yourself having to shout when requesting that remote control, there could be problems with some components of your cooling system.

A system that has been in use for years will have its components and connectors tiring down. You’ll start to hear odd and louder-than-usual noises coming from the equipment.

Get a professional technician to assess the cooling system and find out whether it is fixable. If it’s beyond repair, invest in a new one to enjoy a cool and quiet indoor environment. Below you can see the noise levels of a Mitsubishi Air Conditioning Unit.

3. You Cooling System Is Old

Can you remember the year you installed your air conditioning system? If not, your unit has already reached the end of its usable life.


The average lifespan of a well-maintained central cooling system is around a decade or more depending on its quality. However, if the unit is more than ten years old, it starts to be inefficient.

Consider replacing it with a newer model with the Energy Rating Label. Usually, units that have been in use for more than ten years tend to consume more energy than new ones.

4. Everyday Is a Crisis Day

It’s not normal for a home cooling system to breakdown now and then. With regular maintenance and tune-ups, a functional unit should go for years without requiring repairs.

However, if you’re experiencing abnormal malfunctions and have to call a technician regularly for repairs, upgrade the unit. You’ll enjoy peace of mind and save money on HVAC maintenance and repairs.

5. You Have Excessive and Costly Repairs

When you’re always calling a technician for AC repairs, you end up spending a lot of money in the long run. The more you keep on repairing the unit, the more it continues to cost you money.

Remember, fixing parts of an air conditioner like the coils, motor, and the compressor is more costly than buying a new unit.

Repair Costs

The total cost of multiple repairs is worse than repairing an old unit. Save yourself from frequent and expensive repairs by investing in a new AC.

6. You Are Spending a Lot of Money on Cooling

Heating and cooling account for 20% to 50% of the energy used in Australia homes. However, if a unit isn’t efficient, the energy bills start to skyrocket without any changes in the home’s cooling demands.

Such changes indicate a problem in the energy efficiency of your cooling system. Clean the air ducts and change your filters to restore the effectiveness of the unit.

If these maintenance techniques don’t work, the system may be faulty. Replace it with a new one, and you’ll save a lot of money on cooling in the long run.

7. Your Cooling System Has Broken Parts

Having a home cooling system with broken parts is not safe for you and your family members. If you notice worn wires or defective components and parts, get a new unit as soon as possible to keep yourself safe.

Besides, a unit that goes off frequently may have faulty electrical components. Replace it before it becomes a source of electrical hazards in your home.

8. The Air Quality Is Not as Good as It Used to Be

When a cooling unit gets older, it starts to accumulate dust, allergens, and other air pollutants. Poor air quality can lead to a host of respiratory conditions and allergies.

If the air quality in your home is not as good as it used to be when the unit was new, you need to check the AC. Replace the old filters with HEPA filters.

However, if changing filters and cleaning the AC don’t work, buy a new air conditioning system. You’ll enhance the air quality and protect your loved ones from respiratory diseases.

9. Your Cooling System Is Not Smart

Do you have a smart cooling system? Does your unit have advanced features such as a smart or programmable thermostat or even Wifi? If not, you’re losing out on great convenience.

A smart unit promotes convenience and saves you money in the long run. For example, you can program it to turn on and off and save energy when you’re not home.

If your AC is an old-school unit, replace it with a smart one. The initial cost of installation may be high, but the convenience and energy savings you get are worth it.

10. You Want to Improve Your Home

Do you have a major home improvement project coming up? This is also the best time to trade your old air conditioning unit for a new model.

When remodelling your home, you might want to add some more rooms that require cooling and heating. An upgrade allows you to get a unit that can adequately cool the extra spaces.
