A Family business specializing in car air conditioning services which take no more than 30 minutes at our Derby-based unit. We do a comprehensive leak test before re-gassing using the latest leak detection equipment, we are the only company in Derby to offer this as part of the full AC service. All-most all garages just refill without doing a Nitrogen pressure leak test first, this is so important if you have no refrigerant in the system to test for leaks first otherwise it will just leak out again.


Once you have had your first service with us, all future services will only be £18 incl Vat plus the cost of any extra gas. For more info click here.

New Premises Now Open:- Our Exciting New Workshop Location is Now Open at "Great Northern Classics" on Osmaston Road Derby, While having your Car Air Conditioning Serviced you can visit the large cafe overlooking the workshops visit the museum, browse the car retail shops, or even view the Classic cars on display. Make it a day out with a difference and at no extra charge. You don't need a classic car to book with us, we cater for all vehicles. (We can not do motor-homes or vans at this location). 

Car air conditioning over the years has been given a bad name, due to garages misdiagnosing faults, and making false claims that repairs need doing when they generally DO NOT! Also, they charge huge unnecessary repair bills, due to their lack of experience. Staykool's Aim is to change this perception by offering a totally reliable and honest service and offering cheap repairs if they are needed. Most repairs are relatively cheap if they are needed and should not cost hundreds.

What Makes StayKool Car Air Conditioning Different From The Rest?


Car Air Conditioning servicing and repairs over the years have had a bad reputation from inexperienced operators diagnosing a fault wrongly and charging extortionate prices for repairs. Ring any garage and they will quote around £400 for a new condenser and main dealers around £700!! We can supply and fit for around £150, saving you a small fortune. Staykool offers a totally honest, reliable service and advice. We will diagnose most faults without second-guessing. If we don't know the exact fault we will tell you this, and point you in the right direction. 

Read our reviews on Google, Facebook, and Trustpilot as we have over 1000 Five Star reviews

and have been in business for 8 years and we only specialize in Car Air Conditioning. You can find cheaper alternatives, but do they have the experience and if they find a fault how much will they change? Don't forget that once you have had your first service with Staykool all future services are only £18 plus a small extra for any gas needed between October-April.
