- A/C not cooling due to Freon leaks, low refrigerant, or compressor problems.
- Temperature fluctuates due to contamination, damaged hoses, or intermittent compressor.
- Airflow decreases from faulty radiator fan, dirty evaporator, cracked hoses, or clogged cabin filter.
- Follow four tips to extend A/C life: weekly use, defogging, winter use, checks.
The car’s air conditioning system is essential for comfort during trips, no matter the season. Like other components of the vehicle, the A/C system can develop problems that affect its performance and efficiency. Early recognition of fault signs can prevent costly repairs and extend the life of the entire system.
Main signs that the car’s air conditioning system has problems
Air no longer cools efficiently
- Freon leaks: Worn seals or damaged hoses can allow freon to escape from the system
- Defective compressor: Freon may reach the compressor due to leaks, affecting its operation
- Low Freon level: A reduced amount of refrigerant dramatically reduces cooling efficiency
If you notice this symptom, it’s crucial to visit a mechanic promptly. Early intervention can save the system and avoid the costly replacement of the compressor.
Temperature varies uncontrollably
- Air or water in the system: Contamination can cause blockage of the expansion valve
- Damaged hoses: Cracks in the lines affect pressure and freon flow
- Compressor in need of repair: Intermittent operation of the compressor
- Freon leaks: Gradual loss of refrigerant
It’s important to describe these symptoms exactly to the mechanic for an accurate diagnosis.
Airflow decreases in intensity
- AC radiator fan: The component responsible for circulating air does not function optimally
- Dirty evaporator: Accumulation of impurities blocks airflow
- Cracked hoses: Loss of pressure in the system
- Clogged cabin air filter: Restriction of airflow through the system
These problems require the intervention of a specialist, as diagnosing and repairing them involve specialized technical knowledge.
4 tips to extend the life of the A/C system
1. Turn on the air conditioning weekly
This practice:
- Keeps lubricant in circulation through the compressor
- Prevents seals and rubber components from drying out
- Keeps all moving components functioning optimally
2. Use the defogging function regularly
- Prevents mold growth in ducts
- Removes excess humidity from the system
- Keeps the evaporator clean
3. Use the A/C in winter
- Removes excess humidity from the cabin
- Prevents interior glass fogging
- Keeps all components in working condition
4. Perform preventive checks
- Check the refrigerant level at a specialized service
- Inspect hoses and seals
- Test all system components
- Replace the cabin filter if necessary
These preventive measures can help avoid costly failures and ensure optimal operation of the A/C system in the long term.
