Car Air Conditioning - Norwich

GC Motor Group services and repairs air conditioning systems on most makes and models, working with both R134a and R1234yf refrigerant gases.

If your air conditioning isn’t blowing cold, smells musty when it’s switched on, or seems weaker than it used to be, the system likely needs a re-gas or a closer look at what’s causing the fault.

What weak or warm air conditioning usually means

• Air that’s no longer cold, or noticeably weaker than before is often the first sign the refrigerant gas has dropped below the level needed to cool effectively
• A musty or unpleasant smell when the air conditioning is switched on usually points to bacteria or mould building up in the system, rather than a fault with the gas itself
• Air conditioning that only works intermittently can suggest a small leak somewhere in the system, allowing gas to escape slowly over time
• Unusual noises when the air conditioning is running may indicate an issue with the compressor rather than the refrigerant

Why air conditioning loses its cooling power

All air conditioning systems lose a small amount of refrigerant gas naturally over time, even without a specific fault, which is why performance gradually drops off if the system isn’t serviced. However, a larger or sudden drop in cooling is usually down to a leak somewhere in the system, whether that’s a hose, seal, or another component. Leaving a low system unserviced can also allow moisture to build up internally, which affects performance further and can damage other components over time.

R134a vs R1234yf gas

Most vehicles use either R134a or the newer R1234yf refrigerant gas, and it’s important the correct one is used for your specific car as using the wrong gas type isn’t just a performance issue, it can damage the system and isn’t something any competent garage should do. We identify which gas your vehicle requires and carry out the work accordingly, so there’s no guesswork involved.

What’s involved in an air conditioning service

A typical service includes checking the system for leaks, removing any old or contaminated gas, and re-gassing with the correct refrigerant to the manufacturer’s specified level. We’ll also check the compressor and other key components while the system is open, since catching a developing fault early is usually far cheaper than waiting for it to fail completely.
