Posted by Ace Auto Electrical on September 21st, 2022

Think of a hot day where you have to drive a long way, your car air conditioner doesn’t help you with cool air. Instead, it gives out the air in limited quantity and you cannot bear the heat outside despite pulling down the windows. Whether you have been through this or not, the situation is annoying. The air conditioners are working by the airflow isn’t as normal as it should be.

Whenever you witness something of this sort, you must get in touch with an expert helping out with car ac service in Sydney who will ensure that things are fine before it is too late. Ignoring such an issue can lead to complications and then you will have to spend money for replacing the system altogether. Here are a few reasons why there is poor airflow in your car's air conditioner.

The Growth Of Mould In The Evaporator

Since there is moisture in the unit altogether, there are high chances of mildew and mould making their way. Their growth at the fins of the evaporator can block the airflow. Along with that, when you use the air conditioner despite poor airflow, you are putting your health at risk as their presence can cause issues such as allergies, breathing problems, sneezing, etc.

If you ask the Car Mechanics in Sydney, they would suggest using an anti-bacterial metal cleaner to clean the evaporator that will get rid of mould and mildew. When you use the defrost mode from time to time, the extra moisture in the duct is removed and mould doesn’t receive that environment to grow.

Loose Hoses

The air that has to come from the unit through the evaporator to you needs to flow through a hose. When the hose is loose for any given reason, the air will not reach you and will not keep the car cool. You may not be able to see a loose hose from the dashboard. Therefore, whenever you witness poor airflow, take it to an expert for auto air conditioning in Sydney and they will ensure that things are put in place and you receive cool air all over again.

Blocked Air Filter     

Your car air conditioning unit has a filter that traps dirt, dust, and other debris and allows you to breathe in fresh and clean air. This filter, also known as the pollen filter when blocked doesn’t allow air to pass properly. Therefore, when you aren’t finding the car to be cool when you have switched on the air conditioner, you need to visit the expert on car ac service in Sydney who will clean the filter and bring this to normal.

A Defective Fan

The fan in the air conditioning unit of your car allows the air to blow over the evaporator unit which is mixed with the refrigerant before it comes to the car cabin. If you switch on the air conditioner and do not find the airflow to be normal, there are chances that the fan is damaged or has a defect in it. When it is repaired or replaced, you will again have a comfortable car ride.  

All of these are possible reasons behind poor airflow in your car air condition unit but they need expert attention. The professionals may come up with another valid reason as well which prevents normal functioning. Get your car checked frequently and stay away from such troubles.
