CAR A/C Repairs and Regas PAY LESS at HAE Rockhampton
Regular Aircon services keep you cool and minimise expensive component failure. By maintaining compressor oil level and hose joint seals; your air stays cool
A car A/C service checks refrigerant pressures, compressor operation, airflow, electrical components, and cabin temperature performance. Unlike a basic regas, a full service identifies leaks, worn parts, and efficiency issues to ensure reliable cooling, especially in Rockhampton’s heat.
As time passes, the various components of your car’s air conditioning system can become clogged with moisture, dust, debris, pet hair, and bacteria, along with the general wear and tear of your aircon parts and hoses.
If the A/C is left unchecked, these build-ups can lead to damage to crucial parts, causing costly repairs or replacements. Regular maintenance helps mitigate this risk by allowing early identification of any potential issues through thorough inspections.
This is about your car air-conditioning system and why it doesn't cool as cold as you would like it to.
The diagram to the left is a map of the air-conditioner components and their respective relationships to each other. If one fails they all fail.
Regular maintenance is needed for all car A/C systems to work efficiently and to extend the life of parts. Unfortunately, refrigerants readily soak up water, which makes them corrosive. Some refrigerant loss from your car's system through rubber hoses is typical, meaning a recharge is eventually needed.

To ensure your car's air conditioning operates at its best and most cost-effectively, it should undergo annual servicing.
Second, this will prevent contaminants like air and moisture from entering your system, leading to pressure fluctuations and reduced performance, potentially causing more significant issues. Moisture in a car's A/C system must not exceed 4 ppm.
Your car's A/C system includes a filter/receiver/drier, essential for catching moisture and preventing corrosion. This drying process is a chemical reaction, so it has a limited lifespan. Thus, the filter/receiver/drier must be replaced regularly (e.g., every 2 years or when the system is exposed to air).
What is the Retrofitting all about and why it is necessary?
Car air conditioners used R12 refrigerant from day one until the nineties. R12's damage to the environment, specifically the ozone layer, is a proven fact.
Many world governments, Australia among them, have agreed through protocols to diminish, and finally remove, ozone-depleting substances.
To use R134a, the standard in new cars, old R12 systems need to be changed. This conversion of an old R12 system to R134a is often called retrofitting. Essentially, this involves changing R12 system's ports, replacing the filter, and switching oils.
What causes that unpleasant smell from my car's air-conditioning system?
In regular use, the air conditioner pulls in hot, wet air to the evaporator, causing the moisture to condense. Airborne debris like dirt, dust, hair, and lint clings to wet areas. The evaporator is supposed to self-clean via water droplets, but dust and dirt can trap mould, leading to a foul smell.
Special cleaning products can remove the smell of mould and mildew from your car's AC. We think you should allow us to provide this service. We suggest removing the evaporator for a complete cleaning; this will restore the air passages' functionality.
What is the white vapour that I sometimes see streaming from my car's air-conditioner vents? Is it escaping gas? Is it harmful?
Seeing an odourless, white vapor from your vents but still having a working A/C means it's unlikely to be refrigerant. Refrigerant gas is usually invisible, so if you see it, it's liquid and leaking badly. Then, your system would be totally empty in an hour or two, perhaps even sooner.
Humidity probably causes this white, odourless vapour; tiny water droplets condense from hot, humid air when cooled and then vanish as they vaporize in the warm car air.
The A/Cs cooling chamber causes this when air is too fast to condense moisture. The water vapour is not dangerous and doesn't last, but using recycled air can stop it.
Operational Tips:
In damp weather, using your A/C and heater together clears windows faster. (Your car's engine at normal operating temperature allows for warm, dry air by running the heater and air-conditioner together.
You should try to run your cars A/C system for at least 5 minutes a week regardless of summer or winter weather.
The main cause of poor airflow from the vents.
For a malfunctioning car A/C, early repairs save both hassle and money. Several usual issues cause a car's A/C to have weak airflow; you can fix some, but others need a professional.
The growth of Mould and mildew in your evaporator.
Moisture in car A/Cs creates a perfect space for mould and mildew. This can reduce airflow and cause foul smells, endangering you and your passengers.
Using a good metal cleaner on your evaporator usually removes mold and mildew. Also, be sure to use an antibacterial cleaner to eliminate any dangerous germs. Using defrost mode often will help dry your AC and prevent issues.
Loose hoses or seals
Weak airflow can also be caused by a detached blower hose, stopping air from circulating into the cabin. Also, one seal in the system, essential for proper airflow, might be faulty. Only a professional technician should ever repair or replace hoses and seals.
Blocked cabin air filters
The cabin air filter, also called a pollen filter, is typically located before your blower motor and acts a filtration system between the outside air and the cabin of your car. Any pollens, dirt and leaves or just general road debris gets stopped at the cabin filter to ensure you and your your passengers are only breathing clean air. Cabin filters do not last forever and should be changed every 20,000 km or sooner in severe conditions.
A Faulty fan
Air flows into the cabin after the ventilation fan blows over the evaporator unit, which is cooled by the refrigerant. Without adequate airflow, the fan could be broken, and you'll need a new one.
