How to fix car air conditioning system repairs.

Common Car Air Conditioning Problems and How to Spot Them

​

If your car's air conditioning system isn’t working as it should, it could be due to a range of common issues. To help you identify potential problems before booking a service, here’s an overview of the most frequent AC faults, with insights from our informative videos shown below.

​

1. Warm Air Instead of Cold

If your AC is blowing warm air, this could be due to low refrigerant levels, a leak in the system, or a failing compressor. Low refrigerant often points to a leak, which should be addressed promptly to avoid further damage.

What to check:

• Does the system produce cool air when you first switch it on, but it gets warmer over time?

• Are there any hissing noises, especially when the AC is off?

​

2. Weak Airflow

Reduced airflow can be caused by a clogged cabin air filter, a blocked evaporator, or an issue with the blower motor. Over time, dirt and debris can restrict air from flowing freely through the vents.

What to check:

• Inspect your cabin air filter. If it’s dirty, replacing it might solve the issue.

• Listen for unusual noises when the fan is running, as this could indicate blower motor issues.

​

3. Unusual Smells

If there’s a foul smell when you turn on the AC, it could be due to mold and bacteria buildup in the system. This is especially common in humid conditions.

What to check:

• Do you notice a musty odor right after turning on the AC?

• Look into our antibacterial treatments or smell elimination services for a quick fix.

​

4. Leaking Refrigerant

Refrigerant leaks are a common problem, and they’re not always easy to detect. If your system has had UV dye added in a previous service, you can use a UV torch to check for leaks yourself.

Where to look:

• Around the condenser at the front of the car.

• Along the AC pipes and connections.

• On the compressor and evaporator.

​

5. Unusual Noises

Grinding, clicking, or squealing noises could indicate an issue with the compressor, belt, or other components. Ignoring these sounds could lead to more expensive repairs down the line.

What to check:

• Does the noise increase when you turn on the AC?

• Check for any visible damage to belts or components under the bonnet.

​

6. Excessive Moisture Inside the Car

If you notice moisture or fogging on your windows, this could be due to a clogged drain hose or a problem with the evaporator.

What to check:

• Inspect for water pooling under the car after using the AC. A lack of water might indicate a blocked drain.
