Car Air Conditioning Service
in Wing, Leighton Buzzard
Why is car AC important?
Car air conditioning is mostly used for comfort during warmer, summer months, but it plays a much more important role in your vehicle than simply keeping you cool. A properly functioning AC system contributes to demisting the screen during winter months. The air conditioning system also links with cooling systems on newer electric and hybrid vehicles.
One of the key benefits of air conditioning is maintaining a comfortable cabin temperature, which helps to reduce fatigue. Long journeys in the hotter, summer months can be exhausting without AC, which increases reaction times and therefore, reduces safety. By regulating the temperature, the AC system helps you to stay cool.
In addition to cooling, your car’s AC system is responsible for dehumidifying the air inside the cabin. This is particularly important in damp, colder months, as it prevents the windows fogging up. Clear visibility is important, and a properly working AC system ensures that your windscreen and windows can be demisted quickly, and effectively.
The AC system also plays a role in maintaining good air quality inside the vehicle. This can be especially beneficial for those with allergies or respiratory issues.
Beyond comfort and air quality, regularly using the AC system helps keep its internal components in good condition. The system relies on refrigerant and oil to function correctly. Running the AC periodically, even in the winter, helps maintain pressure, and prevents seals from drying out as it runs oil around the system.
How do I know if my AC is not working properly?
There are several signs that your car’s air conditioning system may not be working as it should. One of the most obvious indicators is weak or warm airflow. If the air coming from the vents is not as cold as it used to be, this may suggest low refrigerant levels, but could also mean there are other problems within the system. If the system is low on refrigerant, then carrying out a leak test is important to pinpoint the issue.
Unusual noises are another warning sign. If you hear rattling, or grinding sounds when the AC is running, it may indicate a problem with the compressor or other parts. These noises should not be ignored as a lot of time, the compressor ties in with the auxiliary belt system.
A musty or unpleasant smell coming from the vents is another common issue. This is often caused by mould, or moisture build-up within the system. This is definitely not a smell you want. Carrying out an air conditioning service can help to reduce moisture within the system. Additionally, running an AC bomb through the system can target mould buildup, helping to reduce the smell.
What causes car AC problems?
Car air conditioning systems are made up of several components, and problems can arise for many reasons. One of the most common causes is low refrigerant levels, often due to small leaks that develop over time.
Another common issue we see is a faulty compressor, which is responsible for circulating refrigerant throughout the system at pressure. If the compressor fails, the AC system will not work at all. Compressors can wear out over time or become damaged due to lack of lubrication, or incorrect lubrication.
Blocked or dirty components can also cause problems. A clogged condenser can reduce the system’s ability to release heat. Moisture build-up inside the system can lead to bacteria and mould growth, which not only affects ability to cool, but also causes a bad smell.
Lack of regular maintenance is a major contributing factor to AC problems in modern vehicles. Over time, refrigerant levels can drop, and components can wear out. Regular servicing helps identify these issues early, and keeps the system running efficiently. Most manufacturers recommend servicing every 2 years.
Frequently asked questions
Can I use my AC in the winter?
Yes, you can and should use your AC in the winter. Running the system helps remove moisture from the screen quicker, making it easier to demist windows and your windscreen. It also helps keep internal components lubricated, and prevents seals from drying out, reducing the risk of AC leaks.
What is the cost of an AC service?
R134a – £84
R1234YF – £144
These prices include VAT. Systems with over 600g will incur an added charge.
How often should I have my AC serviced?
It’s generally recommended to service your car’s AC system every 2 years. Regular servicing ensures the refrigerant is at the correct level, components are functioning properly, and any potential issues are identified early.
Can AC servicing prevent smells and mould?
Yes, regular AC servicing can help prevent unpleasant smells and mould growth by cleaning, and disinfecting the system. Replacing the cabin filter, and removing moisture build-up, reduces the risk of bacteria developing.
