This guide will walk you through some common car AC problems, their possible causes, and how we can help fix them, ensuring your drive is comfortable no matter the weather.

Common Car AC Problems and Their Solutions

1. AC Blows Warm Air

One of the most frequent issues we encounter at Cars Unlimited Auto Repair is an air conditioning system that blows warm air. This problem can often be attributed to:

• Low Refrigerant Levels: Refrigerant is essential for cooling your vehicle’s cabin and may need to be recharged.
• Solution: Our technicians can check for leaks, repair them, and recharge the refrigerant, ensuring proper AC function.

2. Unusual Noises When AC Is On

If you hear rattling or banging sounds when the AC is activated, this could indicate a mechanical problem.

• Loose or Broken Components: Sometimes, the noise may come from a loose belt or a malfunctioning compressor.
• Solution: We can inspect and replace any faulty components to restore the peace and quiet of your ride.

3. AC Emitting a Musty or Moldy Smell

A foul odor when turning on the AC is a common complaint and can make any drive unpleasant.

• Bacteria Build-Up: Over time, mold and mildew can accumulate in the AC system, especially within the evaporator.
• Solution: Our service includes cleaning the evaporator and replacing the cabin air filter to eliminate odors and improve air quality.

4. Intermittent Cooling

If your AC cools intermittently, this can be frustrating and uncomfortable.

• Faulty Thermostat or Electrical Issues: Intermittent cooling often stems from electrical problems or a failing thermostat.
• Solution: We utilize advanced diagnostic tools to identify electrical issues or thermostat failures and resolve them quickly.

5. Weak Airflow

Weak airflow can significantly reduce your system's efficiency, impacting comfort levels inside your vehicle.

• Clogged Air Filters or Blocked Vents: Debris and dirt can obstruct airflow, making the AC system work harder.
• Solution: We check and replace air filters and clear out any blockages in vents and hoses to ensure strong airflow.
