The UK is currently experiencing its fifth heatwave of the year, and for many drivers the air conditioning has gone from an occasional luxury to an everyday necessity.
At AZ Autos, we’ve seen a noticeable increase in customers asking why their car is taking longer to cool down, producing unpleasant smells, or blowing warm air even when the system is set to its coldest setting.
If your air conditioning hasn’t been checked recently, now is the perfect time to make sure it’s working properly before the next spell of extreme heat.
Why your air conditioning matters
A functioning air-conditioning system does much more than keep the cabin comfortable. During hot weather it can:
- reduce driver fatigue on long journeys,
- improve concentration and reaction times,
- help remove humidity from the cabin, reducing misting,
- make travelling with children or pets much safer and more comfortable, and
- prevent unnecessary strain from driving in excessively high temperatures.
When temperatures rise into the high 20s or 30s, a poorly performing A/C system can make even a short commute unpleasant.
Signs your air conditioning needs attention
Look out for these common warning signs:
Weak airflow
If the fan is running but very little cool air is coming through the vents, the system may have a blockage or a failing component.
Warm air instead of cold
This is often caused by low refrigerant levels, but it can also indicate a compressor or pressure-related fault.
Unpleasant smells
Musty or damp odours usually mean bacteria or mould have built up in the system, particularly around the cabin filter or evaporator.
Strange noises
Clicking, rattling, or squealing noises when the A/C is switched on should always be investigated.
What is an air-con regas?
Your vehicle’s air-conditioning system contains a refrigerant gas that gradually reduces over time. Even a healthy system can lose a small amount each year.
An air-con regas involves:
- removing any remaining refrigerant,
- checking system pressures,
- vacuum testing for leaks,
- refilling the system with the correct refrigerant, and
- adding the appropriate lubricant for the compressor.
Many drivers are surprised by how much colder and more efficient their air conditioning feels after a regas.
Don’t wait for it to stop working completely
A common mistake is waiting until the system blows no cold air at all. By that stage, the compressor may have been working harder than necessary, which can lead to more expensive repairs.
Having the system checked early can help identify:
- low refrigerant levels,
- leaking seals or pipes,
- worn compressors,
- blocked condensers, and
- dirty cabin filters restricting airflow.
Simple heatwave checks you can do today
Before your next journey, especially during this period of excessive heat, take a few minutes to:
- start the engine and switch the A/C to its coldest setting,
- check that cold air is produced within a minute or two,
- listen for unusual noises,
- make sure airflow is strong from all vents, and
- inspect the cabin filter service history if you have it available.
If the system struggles with any of these checks, it’s worth having it inspected professionally.
