A well-functioning car air conditioning system is essential, especially in hot, humid weather like that of Queensland’s Sunshine Coast. Whether you’re commuting to work or taking a road trip, you rely on your car’s A/C to keep you cool and comfortable.

Weak or No Cool Air Flow
Possible Causes: Clogged air filters, faulty blower motor, refrigerant leaks.
Weak airflow from your car’s A/C system can be frustrating, especially on a hot day. This issue is often caused by a clogged air filter, which restricts air from circulating through the system, or a faulty blower motor that needs professional attention.
What to do: Regularly check and replace your car’s air filter to avoid blockages. If weak airflow persists, bring your vehicle to Harmac Automotive in Maroochydore, where our skilled mechanics can inspect the blower motor and address refrigerant leaks.
Blowing Warm Air
Possible Causes: Low refrigerant levels, faulty compressor, leaks in the system.
If your car’s A/C is blowing warm air instead of cool, it’s a sign of trouble. The most common cause is low refrigerant, which could indicate a leak in the system. A faulty compressor may also be preventing the A/C from cooling effectively.
What to do: Recharge the refrigerant and check for leaks to ensure the system is sealed. At Harmac Automotive, we use the latest diagnostic technology to identify and fix refrigerant issues and compressor failures.
Strange Odours Coming from Air Vents
Possible Causes: Mould and bacteria buildup, clogged filters.
A musty or foul smell coming from your A/C vents is more than just unpleasant—it’s a sign of mould or bacteria buildup, often caused by moisture trapped in the system. Clogged air filters can also contribute to these odours. You can read more about this here.
What to do: Have your A/C system cleaned and replace any clogged filters. Harmac Automotive offers comprehensive cleaning services to remove odours and restore fresh air flow to your vehicle.
Unusual Noises When A/C Is Running
Possible Causes: Failing compressor, worn belts, or loose components.
If you hear grinding, rattling, or other unusual noises when your car’s A/C is running, it could indicate a serious issue. These sounds often point to a failing compressor, worn belts, or loose components within the system.
What to do: Bring your car to Harmac Automotive on the Sunshine Coast. Our experienced mechanics can quickly diagnose and repair the issue, preventing further damage and keeping your A/C in top condition.
A/C Only Works Intermittently
Possible Causes: Electrical issues, faulty thermostat, or sensor problems.
Does your A/C system only work sporadically? This could be caused by an electrical issue, such as a faulty thermostat or sensor malfunction. Without prompt attention, intermittent cooling may become a bigger problem.
What to do: At Harmac Automotive, we specialise in identifying and fixing electrical issues that affect your A/C system. Let our auto electricians perform a diagnostic test to pinpoint the exact cause.
Water Leaking Inside the Car
Possible Causes: Clogged drain hoses, faulty seals.
Water pooling on your car floor isn’t normal. This often occurs when the A/C system’s drain hose becomes clogged, preventing water from properly draining out of the vehicle. Faulty seals can also allow moisture to leak inside.
What to do: Don’t ignore water leaks—visit Harmac Automotive in Maroochydore, where we can clear clogged drain hoses and fix any seal issues to ensure water is properly drained from your A/C system.
A/C Compressor Not Engaging
Possible Causes: Electrical issues, low refrigerant, or a faulty compressor.
If the compressor isn’t engaging, your A/C system won’t cool properly. This issue could stem from low refrigerant levels, electrical problems, or a failing compressor that needs to be replaced.
What to do: Recharge the refrigerant and check the compressor for functionality. Harmac Automotive uses cutting-edge technology to test the compressor and related components, ensuring your A/C runs smoothly.
