Your air conditioner is one of the most important appliances in your home during the summer months. If it is not working properly, it can make life very uncomfortable! In this blog post, we will discuss how to troubleshoot an aircon that is not cooling. We will cover common problems and solutions, so you can get your AC up and running again in no time!

Why Is My Aircon Not Cooling?

Before we get into troubleshooting, it is important to understand why your air conditioner may not be cooling properly. There are a few common reasons for this:

Air Filter Clogging

One of the most common reasons for an AC not cooling properly is a clogged air filter. The air filter is responsible for trapping dirt, dust, and other particles from entering the AC unit. Over time, the air filter can become clogged with these particles, which reduces airflow and makes it difficult for the AC to cool your home.

Dirty Condenser Coils

The condenser coils are responsible for releasing heat from the AC unit. If these coils are dirty, they will not be able to release heat effectively, which can cause the AC to work harder and not cool as efficiently.

Broken Compressor

It is also possible for the compressor to become damaged or broken. The compressor is responsible for circulating refrigerant through the AC unit. If it is not working properly, the AC will not be able to cool your home effectively.

Defective Thermostat

A defective thermostat can also cause the AC to not cool properly. The thermostat is responsible for regulating the temperature in your home. This means that if the thermostat is not working properly, it will not be able to regulate the temperature effectively, which can lead to an AC that does not cool properly.

Small Air Conditioner, Large Spaces

Always make sure that you are using the correct size air conditioner for the space that you are trying to cool. If you have a small AC unit, it will not be able to effectively cool a large space. This is because the AC unit will have to work harder to circulate air and cool the larger space.

Leaked Refrigerant

If your AC unit is leaking refrigerant, it will not be able to cool your home properly. Refrigerant is responsible for absorbing heat from the air inside your home. If there is a leak, the AC will not have enough refrigerant to absorb all of the heat, which can cause the AC to not cool properly.

Dirty Evaporator

The evaporator is responsible for absorbing heat from the air inside your home. If the evaporator is dirty, it will not be able to absorb heat effectively, which can cause the AC to not cool properly.

Tips for Troubleshooting an Aircon That is Not Cooling

Now that we have covered some of the common reasons why your AC may not be cooling properly, let’s discuss some tips for troubleshooting an AC that is not cooling.

Make Sure The Thermostat Is Set To Cool

The first thing you should do when troubleshooting an AC that is not cooling is to make sure that the thermostat is set to “cool.” If it is not, then the AC will not turn on. Before you do anything else, double check the thermostat to make sure it is set to “cool.”

Inspect Circuit Breaker Box

If the problem of your aircon is not cooling persists, check the circuit breaker box to see if the AC unit has tripped a breaker. If so, simply reset the breaker and see if that solves the problem.

Clean Dirty Aircon Filters

The next thing you should do is clean any dirty air filters. As we mentioned before, a clogged air filter can reduce airflow and make it difficult for the AC to cool your home. To clean the air filter, simply remove it from the AC unit and rinse it off with water. Let the air filter dry completely before putting it back in the AC unit.

Check If There’s Ice Build-Up In The Aircon

Ice can also build up inside the AC unit, which can reduce airflow and make it difficult for the AC to cool your home. To check for ice build-up, simply remove the air filter and look for any ice that has built up on the coils. When troubleshooting an AC that is not cooling, always make sure to check for ice build-up. To thaw the ice, simply turn off the AC unit and let it thaw on its own.

Wrapping it up

As you can see, there are a few different reasons why your AC may not be cooling properly. By following the tips we have discussed in this article, you should be able to troubleshoot an AC that is not cooling and get it working again in no time. When in doubt, always consult a professional technician for air conditioning repair service. They will be able to diagnose the problem and get your AC unit up and running again in no time.
