Car Air Conditioning Leaks — What You Need to Know

Car air conditioning systems run at high pressure, which makes them more likely to develop leaks. The most common causes include:

Corrosion inside or outside the pipes.
Stone or debris damage to the condenser (the radiator-like unit behind the front grille).
Seal failures when the system is under pressure.
Faulty pressure relief valves on the compressor.

When a leak happens, the refrigerant gas escapes and your air conditioning stops cooling properly.

StayKool Leak Guarantee (with Extreme Leak Sealer)

For extra reassurance, if you request the Extreme Leak Sealer during your service, you’ll get our 3-month Leak Guarantee.

Here’s how it works:

If your air con leaks within 3 months, once the leak is repaired by either your own garage or one of our recommended mechanics, we’ll re-gas your car for free.
The Extreme Leak Sealer fixes over 90% of leaks, but there’s always a small risk that the leak could re-open under pressure.
If you were planning to repair the leak anyway, you have nothing to loose by trying it first.

⚠️ Important: Please don’t choose the Extreme Leak Sealer unless you are happy to accept a small risk that it may not work.

Fast Priority Booking

If your system leaks, we give you priority appointments so you can be booked in quickly — usually within 2 days — even during the busy summer months.

Terms of the Leak Guarantee

To qualify for the free re-gas:

You must report the issue (your air con has stopped working) within 3 months of the original service.
Repairs must be carried out by a recognized garage or one of our recommended mechanics, and you’ll need to provide the repair invoice.
Contact us by phone or text so we can book you in straight away for the free check — do not book online, otherwise an appointment charge applies.
Only one claim is allowed within the 3-month period.
You must have requested the Extreme Leak Sealer at the original service.
If the problem is mechanical (not a leak), a £35 appointment fee will apply.
We only recommend this guarantee if we believe there’s at least an 80% chance of success. If the chance is lower, we’ll explain your options.
If you use your own garage and the leak continues because of poor workmanship (e.g., a badly fitted seal), a £35 fee will apply. This charge does not apply if one of our recommended mechanics carries out the repair.
This guarantee does not apply to vehicles with rear air conditioning, as those systems can’t be fully tested.
The guarantee only applies to our full-price services and does not cover discounted promotions, such as the Winter Offer or other reduced-price deals.
