Most people don’t appreciate their Car’s AC System, until the day it stops running of course! To keep your AC running at peak performance for longer, there are a few things you can do to maintain your car’s AC system. 

It is important to note, that although there are some things you can do yourself to look after your AC, we always recommend that any work on your AC system should be carried out by a licenced technician with the correct AC equipment. 

Regular Use

Switching on your car’s AC for a few minutes every week will help keep the system lubricated. We recommend running your air conditioning for at least 10 minutes at full power (on cold). This is especially important to do in Winter. If the system sits for long periods of time without use, this increases the risk of seals and hoses hardening or breaking, potentially causing leaks in the system. 

Keep It Clean

A simple way to help prolong the performance of your AC System is to regularly replace your cabin filter. This seemingly minor part is your evaporator’s first line of defence against the elements. It filters out the dust, dirt, leaves and other debris from outside, preventing it from entering the AC system and clogging up major components. Due to the nature of their function, they can become breeding grounds for bacteria and mildew. This is why we recommend getting them replaced every few years. 

It is important to note that in many vehicles, the cabin filter will only be filtering the air that is entering the vehicle from outside. If your AC System is on re-circulate is it pulling air from the cabin straight through to the evaporator. For this reason, we also recommend keeping the inside of your car free of pet hair, dirt and other debris (in particular the front seats).  

Should your system start to present some unusual smells or restricted airflow, this could be a sign of bacteria or mould in the system. Thankfully there are inexpensive Anti-Bacterial treatments that can be used to eliminate these contaminants. These treatments are great for keeping your AC system smelling fresh and free of allergens and other nasties. 

Dry the Evaporator

If you’ve been running the AC system non-stop this can cause moisture build up in the evaporator core. This can lead to a build-up of bacteria, mould or mildew. To prevent this, we recommend drying out the evaporator regularly by running the AC in defrost mode for 5-10 minutes. Another option is to turn the AC off (with the fan still running) a few minutes before you reach your destination. This gives the evaporator time to dry off excess moisture using the hot air from the engine.

Monitor for Changes

It is important to monitor your AC system for any changes in performance. This could be a change in how the system sounds when its running, or a strange smell coming from the vents, or a change in the air flow temperature. Noises can be a sign of mechanical fault, smells can be caused by bacteria build up and air flow can be affected by any number of things.

In almost all cases, the sooner the fault is identified the easier (and often cheaper) it is to repair. If faulty or damages components are left unattended to, they run the risk of damaging more components down the track. Consequential damage is all too common in AC systems. This is why we always recommend getting your vehicle assessed by a qualified technician as soon as you notice any changes in the performance of your AC system.   

Regular Servicing

Just like your car’s engine, the best way to keep your AC system at peak performance is to have it serviced regularly. Having your system thoroughly tested and inspected by qualified and licenced technicians is the best way to ensure its longevity. Regular servicing also helps to catch any issues or faults early, usually making it cheaper and easier to fix.
