ABOUT us
We are a father and son family-run car air conditioning servicing business with premises at Verbena Drive, Littleover, Derby. Most services take no more than 30 minutes. We only specialize in car air conditioning so you can be assured of a high-quality service.
Qualified to City & Guilds 7543 standards
We do not just top up your car with refrigerant, we always remove your old refrigerant. We vacuum the entire air conditioning system to -29 hg to remove any excess moisture; then test for leaks under vacuum. We also pressure test the system with Nitrogen to find any leaks that may be present.
Additional extras to Enhance the Perfomance
COOL-SHot Additive only £30 extra incl vat
Using Cool-Shot will improve the performance of the system, creating a cooler environment, whilst using less energy and increasing the ac systems lifespan saving money in the long term.
Cool-shot comprises of two synthetic catalysts and a lubricating agent, which removes the build-up of oil on the walls, allowing the refrigerant to improve its heat exchange properties.
Using case histories interesting data has emerged using cool-shoot.
-
Up to a 5-degree improvement in cooling at air vents.
-
Faster cooling performance
-
73% better heat exchange
-
20% reduction in fuel costs to run the compressor
-
54% increase in compressor lubrication
-
50% increase in compressor lifetime.
-
A decrease in compressor vibrations and noise.
-
Cool-shot acts without causing any chemical changes to the oils or refrigerant and is 100% ecological.
Using Cool-shot will pay for itself in no time at all, using less energy to run the compressor and fewer maintenance costs and quieter operating noises.
Extreme leak Sealer Additive only £30 extra
Safe-harmless to system and recovery components. Non-reactive to humidity and air. Compatible with all refrigerant gasses. Polymer-free- does not clog system compressor or recovery machine.
-
Fixes leaks up to 0.3mm
-
Reconditions seals
-
Lubricates Compressor and makes it run quieter.
-
Non-polymer based so will not clog the system like other sealers.
-
Saves money overtime as it works to stop any future leaks.
Free UV-Dye treatment
(Included in full service)
What Is UV Dye?
UV dye is a specially formulated fluorescent dye added to your AC system along with the refrigerant and oil. It circulates throughout the system and, if there’s a leak, the dye escapes with the gas. Using a UV torch, leaks become instantly visible under ultraviolet light.
Benefits of UV Dye in Your AC System
Quick & Accurate Leak Detection
Leaks can be hard to spot with the naked eye, especially tiny ones that cause slow gas loss. UV dye makes it easy to pinpoint the exact location of any leaks, whether it’s in the condenser, pipework, or seals.
Saves Time & Money on Repairs
Without UV dye, leak detection can be expensive and time-consuming, often requiring re-gassing multiple times before the problem is found. UV dye eliminates guesswork, helping us (or any mechanic) find the leak quickly and prevent unnecessary costs.
Works Over Time
Even if your AC seems fine today, UV dye stays in the system for future checks. If a problem develops later, you (or a technician) can inspect for leaks with a simple UV torch—no need for another full diagnostic session.
Prevents Further Damage
A leaking AC system isn’t just an inconvenience—it can lead to costly damage if left untreated. Running the system without gas can cause seals and valves to dry out, potentially leading to expensive repairs. UV dye helps catch issues early, protecting your system.
Standard in Our Service
At Koolcar, we include free UV dye with every air con recharge. That means if a leak develops later, you’ll already have a built-in detection system—just shine a UV light to check!

How Car AC works
The Air conditioning system consists of these parts:
-
Condenser
-
Compressor
-
Receiver
-
Dryer
-
Evaporator
-
Expansion Valve
The Refrigerant enters the compressor as a vapor and is compressed by the compressor, where the pressure increases and it enters the condenser at the front of your car (looks like a radiator) where it is collected and it turns into a liquid.
The liquid refrigerant then enters the evaporator under pressure (Look like a radiator, that is hidden behind the dashboard). It then turns back into a vapor, and due to the laws of physics it supercools, and warm air from the interior of the car is blown over the evaporator, which extracts the heat into the refrigerant, It then enters the compressor again and keeps repeating the cycle.
Using your air conditioning system keeps it working efficiently if you do not use it the seals may dry out and cause leaks. And, any moisture trapped in the system can cause acid to attack the components, so use it regularly to keep it working and prevent garage bills!
