If your air conditioning system isn’t keeping you cool, then it could be time to book an air con regas.
Sometimes known as an air con recharge, the refrigerant in your car’s air con system will be refilled during a regas.
Read on and find out what an air con regas is, how much this costs and why you should book one.

What Is Air Con Regassing?
Air con regassing is a process in which the old refrigerant gas from your car’s air con system is removed and replaced with new refrigerant.
Without adequate refrigerant, the AC can’t cool the air effectively.
Why Should I Book an Air Con Regas?
Booking a timely air con regas offers a host of benefits for your vehicle, including:
- Improved cooling efficiency
- Enhanced fuel efficiency
- Prolonged AC system lifespan
- Improved air quality
Not to mention that this can help you prevent costly repairs and potentially even increase the resale value of your vehicle.
For your comfort and convenience, booking an air con regas is always a good idea.
How Much Is an Air Con Regas (UK)?
An air con regas can cost anywhere from £40 to upwards of £200 in the UK.
The price can vary depending on the type of refrigerant your car uses.
How Often Should You Regas Air Con?
Generally speaking, your car’s air conditioning system will need regassing every 2 years.
You should book an air con regas sooner than this if you use it more regularly.
Does My Air Con Need Regassing?
Your car air con may need regassing if it is no longer blowing cold air when you turn the system on.
If you notice that the AC system is taking longer to cool the space or there are any strange leaks, noises or smells coming from the AC unit, then you should definitely book an air con regas.
How Long Does an Air Con Regas Take?
An air con regas can take anywhere from 30 minutes to an hour to complete.
Not long at all to ensure your air con is working as it should!
Can You Recharge Air Con Yourself?
Whilst it is technically possible to top up your car’s air con gas yourself, we would strongly advise that you take your vehicle to a garage to minimise the risks.
If not handled safely, you could accidentally injure yourself or cause a chemical reaction if different types of air con gas are mixed.
Not to mention that you could do damage to integral parts of the air con system.
Given that an air con regas is a critical maintenance task that ensures your AC system is operating effectively, it’s best to leave this to a professional technician.
Don’t wait until a heatwave to sort out the problems with your car’s AC!
FAQs
Frequently asked questions
In January 2017, a new law was introduced that required all new cars be fitted with 1234yf gas, which is more environmentally friendly.
Since 2013, certain car manufacturers have fit their vehicles with this new gas – even before this law was enforced.
The EU banned the previous refrigerant gas – known as R134a – from being used in the AC systems of new cars back in 2011.
Even so, R134a will remain in production for some time if your vehicle is old enough to use this air con gas.
Regardless of whether your car is new or not, you should check which gas it needs if it was manufactured in or after 2013.
You can consult your owner’s manual or check the under bonnet label in your car to find out which air con gas your vehicle uses.
