Car and Van Air Conditioning Servicing and Maintenance
Car air conditioning plays a key role in your driving comfort all year round. It keeps you cool in summer, helps demist your windscreen in winter and filters the air you breathe.
Just like engine oil or brake fluid, your air conditioning system needs regular checks to keep it working properly. Over time, things like air con gas and filters can wear out, which might affect how well your system runs.
If maintenance is skipped, you could notice weaker airflow, odd smells, foggy windows, or even a complete system breakdown. That’s why it’s a good idea to look after your air conditioning and keep it in great shape.
Whether you need a quick performance check, a full recharge, or a thorough clean and disinfection, we offer a range of air con services to suit your vehicle and your budget.

Risks of not maintaining your air conditioning
If your air conditioning system isn’t looked after, it can affect both comfort and performance. Over time, wear and build-up can lead to mechanical problems and unpleasant smells.
Here’s what might happen if you delay maintenance:
- Cooling not effective as it used to be
- Fogged-up windows and poor visibility
- Musty or unpleasant smells
- Bacterial or allergen build-up
- Increased fuel consumption
- Risk of compressor damage due to low refrigerant
If you notice any of these signs, it's time to schedule a check.

Air conditioning services for electric vehicles
Electric and hybrid vehicles use air conditioning to keep you comfortable and to help regulate battery temperature. Our centres have the right tools and refrigerants to service these systems properly.
If you drive an EV, make sure your air con service is done by a qualified technician. ATS Euromaster offers maintenance tailored to modern electric air conditioning systems, including high-voltage component safety.
Tips for maintaining your air con
Using your car’s air conditioning the right way helps keep you comfortable, extends the system’s lifespan, and can reduce running costs.
Here are some expert tips:
- Use your air con regularly, even in winter. This prevents the seals from drying out and helps keep the system clean.
- Avoid starting your journey with the AC on full power. Open the windows first to let the hot air out, then switch on the system.
- Don’t set the temperature too low. Aim for a comfortable setting to avoid overworking the compressor.
- If you notice bad smells or misty windows, it's time for a check.
- Regular servicing helps prevent unpleasant odours, poor airflow and expensive repairs.

Car air conditioning: your questions answered
We recommend a regas every 2 years. If you notice reduced airflow, smells, or warm air, get it checked sooner.
It’s often due to low refrigerant levels. In that case, your system likely needs a regas.

Moisture and bacteria inside the system can create unpleasant odours. An antibacterial clean eliminates these and refreshes the air.
Most cars use either R134a or R1234yf, depending on their registration year. Vehicles from 2017 onwards generally use R1234yf.
Every two years, unless you notice poor cooling or airflow earlier.
Cleaning the evaporator, removing bacteria, checking lubricant and refrigerant levels, and a free temperature check.
Yes — the refrigerant (coolant) absorbs heat from the cabin and releases it via the condenser.
Abnormal noises or no airflow may indicate compressor issues, leaks or electrical faults.
Yes. The heating and cooling systems are both part of the climate control circuit. A failure in one may affect the other.
