Why your car air-con is blowing hot air instead of cold air
Learn the common causes of problems with your car’s air-conditioning system, which is crucial in a tropical climate.
Nothing ruins a road journey faster than the air-conditioner in your car blowing hot air on a scorching afternoon. Understanding the root causes can save you a sweaty ride and the precious money in your wallet. Let’s cover the usual culprits and possible solutions for this problem.
1. Refrigerant level is low
Your car's all-important air-con system relies on refrigerant to cool the air. A leak in the system could cause the refrigerant level to drop, which would turn your cooling dreams into a frustrating nightmare. Get it topped up, or better still, have it inspected!
2. Compressor issues
The compressor is the heart of your air-conditioning system. If it’s malfunctioning, the refrigerant won’t circulate properly. A bad compressor might need repair or replacement.
3. Clogged air filter
A dirty air filter blocks the airflow, leading to poor cooling performance. Check and replace your air filter regularly to keep your car’s A/C running smoothly.
4. Faulty cooling fan
The cooling fan dissipates heat from the refrigerant. If it is damaged, the refrigerant stays hot, and so does the air piped into your cabin.
5. Electrical problems
Wiring issues or blown fuses could cause a breakdown in the air-con system. These need to be diagnosed and fixed by a professional.
