Air Conditioning Refrigerant Recharge -
An air conditioning refrigerant recharge (often called a regas) is the process of restoring the correct type and amount of refrigerant inside your vehicle’s aircon system so it can operate efficiently and deliver proper cooling. Over time, small amounts of refrigerant naturally escape through seals, joints, and components, which reduces the system’s ability produce cold air.
Aircon systems lose small amounts of refrigerant over time, so a recharge can help restore colder air and better performance.
What is an aircon recharge?
An aircon recharge restores the correct amount of refrigerant in the air conditioning system. Our technicians tests the system for leaks then charges the system to the vehicle manufacturer’s specified levels using calibrated scales.
Key Points -
A recharge restores naturally lost refrigerant
Modern vehicles use different refrigerants (R134a or 1234yf)
A recharge restores correct system pressure for optimal cooling performance
A gradual drop in cooling is common over time. A proper regas restores the correct gas level and helps bring back colder, stronger air.
How much does a recharge cost?
The cost of a recharge depends on the type of refrigerant your vehicle uses. Most vehicles fall into one of two categories: R134a or R-1234yf.
R134a is typically used in vehicles older than 2016 and is more affordable due to lower gas costs. The cost of a R134a recharge is £59.99.
R-1234yf is used in vehicles 2017 and newer and is significantly more expensive due to higher production and supply costs. The cost of a R-1234yf recharge is £99.99

When do you need a recharge?
-
Air blows warm or not as cold as before.
-
Temperature fluctuates or cooling is inconsistent.
-
Hissing noises from the system or visible oil at pipe connections.
-
Cabin takes longer to cool down, even while driving
-
Sweet or unusual smell inside the car (sometimes a refrigerant or oil smell).
Symptoms that indicate low refrigerant
-
Slow leak from seals, hoses, or service ports.
-
Loss after repair work where the system was opened.
-
Normal gradual loss over many years in older systems.
-
Damage from collisions or rodent chew.

What We Do On Site -
Refrigerant Recovery
Any remaining refrigerant is safely extracted from the system using specialist equipment. This allows the current gas level to be measured, helping identify whether the system is low due to natural loss or a potential issue.
System Vacuum & Leak Check
The system is placed under deep vacuum to remove moisture, air, and contaminants that affect performance. This stage also highlights any leaks or pressure faults, ensuring the system is sealed and operating correctly before refilling.
Precision Recharge
The system is recharged with the exact manufacturer-specified type and quantity of refrigerant. Pressures are balanced to ensure efficient operation, restoring strong, consistent cooling while protecting key components like the compressor.
If a leak is found we explain repair options. Small seals and O-rings can often be fixed on site. Major repairs are quoted before work proceeds.
