Top myths about your car air conditioning system
Myth #1 - It’s a closed loop system, therefore needs no maintenance
Air con compressor oil is subjected to great heat & stress, second only to engine oil. Overtime, oil breaks down & becomes acidic, causing wear, corrosion, reduced cooling efficiency & increased fuel consumption. The compressor works harder, failing prematurely & requires costly repairs.
Myth #2 - Changing air con cabin filters regularly is sufficient to ensure clean air from your car’s AC
Unless your car is a top-end car using HEPA ( High efficiency Particulate ) air con filter, this is totally untrue. Bacteria & other harmful microbes thrive in dark & moist areas such as your air con evaporator. Our high humidity ensures that the evaporator remain wet for hours after the engine is switched off. In just a few months, any new car’s air con will be filled with mould & bacteria, which conventional air con filters are unable to remove. HEPA filters also reduce airflow drastically & thus are not suitable for normal cars.
Myth #3 - Wait a minute, I use a cluster ioniser in my car, I should be ok!
Ionizers cause dust & other particles to form clumps, which tend to settle more quickly. This means that you do breathe in fewer impurities, but those that you do not breathe in are likely to be in larger lumps. Sounds worse, doesn’t it?
Myth #4 - Air Con maintenance actually causes AC failure
If you have an old car & never performed air con maintenance, your air con evaporator can be corroded & your compressor may fail or jam soon. In this case, servicing the air con could lead to failure. However, with newer air con compressors, which are still working fairly well, regular change of air con compressor oil ( every 20,000km ) prolongs your air con compressor’s lifespan.
How many times do you have your home’s air conditioning serviced & maintained? Perhaps 2-3 times a year? The service job includes refrigerant top up, filter & blower cleaning to ensure you have a clean & cool air. The question is, how many times do you have car’s AC system serviced in a year?
