4 Common Car AC Problems

May 07, 2024

Your car's air conditioning is invaluable, especially during summer or in hot climates, guaranteeing a comfortable ride. It eliminates the need to pull down windows and experience discomfort from the wind. Your vehicle's AC ensures better road safety by avoiding the drowsiness associated with being too warm and removing windscreen mist.

Besides regulating temperature, air conditioning also filters out pollutants, producing cleaner air in your vehicle. However, some issues can significantly impact the system's proper function, making your automobile uncomfortable. Discussed below are four common car AC problems.

1. Refrigerant leak

Your car's air conditioning heavily depends on refrigerants to keep you cool during summer. Refrigerant leaks are among the top car problems. Signs your vehicle's refrigerant is leaking include:

- Low airflow: If your vents have low airflow, it could be due to the low quantity of refrigerant, which makes the compressors harder than normal, resulting in poor cooling and reduced airflow

- Warm air: If your car is blowing warm air, it’s probably a refrigerant leak

Unpleasant smells and unusual noises are other symptoms of a refrigerant leak. Corrosion or damage to your components and age or wear and tear of your components could be the reason for a refrigerant leak. A refrigerant repair service or complete AC replacement can help prevent a refrigerant leak.

2. Dirty air cabin filters

Air cabin filters usually filter out exhaust gasses, pollen, and dust before going into your automobile's cabin. The filter ascertains that the air circulating in your car is contaminant-free and clean. Besides preserving the air quality in your vehicle, air cabin filters also safeguard critical HVAC parts from dust, helping maintain the system's longevity.

Neglecting your air cabin filter makes the car's AC work extra hard to circulate air, reducing the AC and heater's efficiency. This translates to longer cooling and heating periods in your automobile's interior and accelerates the AC's wear. A clogged filter implies that more allergens and pollutants will enter your car and negatively impact your health. Ensure regular cleaning of the air filters for property function and longevity.

3. Broken or blocked condenser

When your car's AC condenser isn't good, the air conditioning blows hot air. Since a condenser re-cools hot refrigerant, its blockage means it will have a hard time cooling well and will start blowing out hot air. If the condenser isn't blocked and is still not functioning, it could be because it's broken. Seal leakage could be another reason for your car's AC condenser failure. Signs your vehicle's condenser is in poor condition include:

- The air your vehicle emits isn't as cold as it should be

- Vents are releasing a burning smell

- Refrigerant is leaking

Replacing your car's AC or replacing its parts can help prevent the issues associated with a blocked or broken condenser.

4. Electrical problems

Car AC issues may occur due to electrical problems in your automobile, including:

- Broken temperature sensors

- Blown fuses

- Damaged wires and more

These issues can cause your car's air conditioning to stop functioning completely or not work correctly. If not addressed on time, electrical problems can lead to potential acid buildup, severe corroding, and damaging components, necessitating a complete replacement. Most electrical issues can also cause AC failure. Keeping up with car AC maintenance can help prevent these problems.
